The use of quality of life instruments to evaluate the effects of cancer and its treatments on patients has increased, but understanding the roles that fatigue and depression play on quality of life is still complicated. Earlier studies have examined the individual effects on the quality of life of cancer patients. The purpose of this study was to investigate whether gender is related to the effects of fatigue and depression on quality of life. This study also examined the interactional effects of fatigue and depression on quality of life. The current study found no significant differences on reports of quality of life between genders. Additionally, this study found that depression and fatigue were moderately correlated. Depression and fatigue were also found to account for a proportion of the variance in the quality of life domains of physical, functional, and emotional wellbeing. However, the interaction effects were minimal, but were significant predictors of total quality of life in females, but not male, cancer patients.

Studies assessing the reliability of the Borg rating of perceived exertion (RPE) scale for regulating exercise training intensity have reported mixed results. Differences in experimental designs and analytical techniques make it difficult to compare results. The purpose of this study was to examine the reliability of perceptually-based treadmill (TM) exercise. Eleven subjects (42.5 ± 19.5 yrs) completed a maximal test (GXT) and 3 RPEproduction trials (PT) on a TM. Each PT consisted of two 10-minute bouts where subjects selected speeds and grades to elicit an intensity equated with an RPE of 11-12 (RPE-L) and RPE of 15-16 (RPE-H). Speed and grade, heart rate (HR), oxygen uptake (V02), and ventilatory equivalent for oxygen (VE/V02) were assessed throughout the GXT and the last 3 minutes of each PT. Blood lactate concentration (BLC) was assessed at RPE-L and RPE-H during the GXT and at the completion of each PT intensity. Reliability was assessed using an ANOVA with repeated-measures, intraclass correlations, and absolute differences (ABS A) across the PTs at each intensity. No significant meangroup differences were noted in any of the physiological variables at either intensity across the PTs. Reliability coefficients were higher for the selected workload and the metabolic measures than for HR or BLC. Reliability increased across trials for all measures, and as a function of intensity for V02 (L = 0.91 & H = 0.98), HR (L = 0.60 & H = 0.84), and BLC (L = 0.50 & H = 0.64). Mean ABS A evaluated the inter-trial reliability for HR (bpm) and V02 (METS) at the low intensity PT 1 vs. PT2 = 013 bpm; A3.3 METS, PT 1 vs. PT3 = 010 bpm ; A3.3 METS, and PT2 vs. PT3 = A7 bpm; 01.6 METS and the high intensity PT 1 vs. PT2 = 011 bpm; A2.5 METS, PT 1 vs. PT3 = 011 bpm; A3.4 METS, and PT2 vs. PT3 = A9 bpm; A2.2 METS, respectively. Mean ABS A decreased for HR and V02 between PT2 vs. PT3. These data suggest that reliability of perceptually-based TMexercise varies among physiological measures and various analytical techniques, and individual variation in physiological data across PTs should be considered prior torecommending RPE for the self-regulation of exercise.

ENGLISH ABSTRACT: The Job Characteristics Model (JCM) is one of the most widely used and researched models in the field of Industrial Psychology. It has provided industry with useful solutions for its people-related business problems through the rearranging of the physical and psychological characteristics of jobs in order to address demotivation, dissatisfaction and marginal performance. The JCM has also endured a fair amount of criticism, however, specifically pertaining to the mediating role of the psychological state variables. Research findings on the model are divided into two camps. Some researchers argue that the model is empirically sound; while others believe the model should be discarded or adjusted. These studies were done circa 1990, however, when most of the advanced statistical analysis techniques utilised today were not available. Research related to the JCM has been decreasing steadily since then, and it seems that no final verdict was reached regarding the utility and validity of the model. The overarching objective of this study is to provide closure regarding this discourse by testing the three major theoretical postulations of the JCM in the South African context on a sample of 881 students with an ex post facto correlational research design. This was achieved by utilising structural equation modelling via LISREL. Three separate structural models were fitted and compared. The first model was a simplified version of the original model (Hackman & Oldham, 1980). The second model excluded the mediating psychological states proposed by Boonzaier, Ficker and Rust (2001). The final model had the same basic structure as the first model, but more causal paths were included between the job characteristics and the psychological states. The results show that more variance in the outcomes is explained with the inclusion of the psychological state variables. The psychological states are therefore a crucial component of the model. Although these findings corroborated the original model, the third model displayed superiority in terms of accounting for significant amounts of outcome variance in the dependent variables. These findings indicate that the job characteristics predict the psychological states in a more comprehensive manner than originally proposed in the literature. Job design interventions thus remain a useful tool and industry should utilise the suggested interventions. Furthermore, this study proposes preliminary equations (a Motivating Potential Score and resource allocation) that may be used to determine the relative importance attached to each job characteristic in the world of work.
AFRIKAANSE OPSOMMING: Die Taakeienskappe Model (Job Characteristics Model, JCM) is een van die Bedryfsielkunde-modelle wat die meeste gebruik en nagevors word. Dit het aan die bedryf bruikbare oplossings vir mensverwante besigheidsprobleme verskaf deur die herrangskikking van die fisiese en sielkundige eienskappe van werk om probleme soos demotivering, ontevredenheid en marginale prestasie aan te spreek. Die JCM is egter ook al baie gekritiseer, spesifiek rondom die bemiddelende rol van die sielkundige toestand veranderlikes. Navorsingsbevindinge oor die model word in twee groepe verdeel. Die een groep argumenteer dat die model empiries foutvry is, terwyl die ander groep glo dat dit weggedoen of aangepas moet word. Hierdie studies is egter in die 1990’s gedoen, toe die meeste van die gevorderde statistiese tegnieke wat vandag gebruik word, nie bestaan het nie. Navorsing oor die JCM het sedertdien stadig maar seker afgeneem, en geen finale besluit oor die bruikbaarheid en geldigheid van die model is al geneem nie. Die oorkoepelende doel van hierdie navorsing was om van die bogenoemde probleme te probeer oplos deur drie vername teoretiese uitgangspunte oor die JCM in die Suid-Afrikaanse konteks te toets deur middel van ‘n steekproef van 881 studente. Dit is met behulp van struktuurvergelykingsmodellering deur middel van LISREL gedoen. ‘n “Ex post facto” korrelasionele navorsings ontwerp is benut. Drie aparte strukturele modelle is gepas en vergelyk. Die eerste model was ’n vereenvoudigde weergawe van die oorspronklike een (Hackman & Oldham, 1980). Die tweede model het die bemiddelende sielkundige toestande uitgelaat wat deur Boonzaier, Ficker en Rust (2001) voorgestel is. Die finale model het dieselfde basiese struktuur as die eerste een gehad, maar nuwe oorsaaklike weë is tussen die werkseienskappe en sielkundige toestande ingesluit. Die resultate toon dat meer variansie in die uitkomstes verduidelik word wanneer die sielkundige toestand veranderlikes wel ingesluit word. Die sielkundige toestande is dus ’n kritieke komponent van die model. Hoewel hierdie bevindinge die oorspronklike model staaf, het die derde model die noemenswaardige variansie in uitkomstes van die afhanklike veranderlikes beter verklaar. Hierdie bevindinge dui daarop dat die werkseienskappe die sielkundige toestande meer omvattend voorspel as wat aanvanklik in die literatuur voorgestel is. Werksontwerp-intervensies is dus nog steeds ’n bruikbare hulpmiddel en die bedryf moet die voorgestelde intervensies gebruik. Hierdie studie stel ook voorlopige vergelykings voor (Motiverings Potensiaal Telling en hulpbrontoewysing) wat gebruik kan word om die relatiewe belangrikheid van elke werkskenmerk in die wêreld van werk te bepaal.

Mutations in BRCA1 and BRCA2, the first two breast cancer susceptibility genes identified, carry as much as an 85% lifetime risk of developing breast, ovarian or other cancers. Genetic testing for mutations in these two genes has recently become commercially available. There have been varying amounts of psychological distress noted among women with a family history of breast cancer. Distress has been observed to impact psychological functioning, activities of daily living, and the practice of breast cancer surveillance behaviors. Within the genetic screening process, psychological distress has been shown to impact the decision to undergo genetic screening, the comprehension and retention of risk assessment information, as well as affecting the subject following the receipt of the genetic test results. Little work has been done to examine predictors of distress within at risk subjects. This study examines psychological distress among 52 community women presenting for BRCA1 and BRCA2 genetic mutation testing. Predictors of distress included family cancer history, education, age, Ashkenazi ethnicity, and Internality and Powerful Others Health Locus of Control. Vulnerable sub-groups of patients include younger women, women with higher levels of education and women of Ashkenazi ethnicity.

This research was a pilot study at improving the medical, psychiatric and addiction care provided to women detainees at the jail. Few studies have been completed with women atjail intake, yet the population is suspected of having a multitude of medical, psychiatric and addiction in jail treatment and community reentry needs. Utilizing a descriptive, cross-sectional survey design, the following aims were completed for this pilot study: documented the creation of a nursing research infrastructure within a large jail; compared the results of the traditional 16- item paper and pencil Intake Service Center Screen with the 8-item paperless Brief Jail Mental Health Screen obtained via Audio Computer Assisted Self Interviewing (ACASI) technology; compared Addiction Severity Index scores and addiction treatment motivation and readiness scores obtained via ACASI technology with normative data; assessed the frequency of HIV risk behaviors and the medical, psychiatric and addiction treatment needs obtained via ACASI technology; while assessing the frequency and the average length of time for screening by providers at the jail via medical chart review. The results showed that the ACASI technology proved to be more effective than paper and pencil methods. This technology not only assessed detainee treatment needs, but simultaneously created reentry/discharge plans. The study demonstrated that HIV risk behaviors and the prevalence of past suicide attempts were high among the participants. The Addiction Severity Index scores and the Circumstance Motivation and Readiness scores demonstrated that methamphetamine addiction, and mental health severity is high among this population however motivation and readiness for treatment arc low. Therefore, recommendations for the most suitable jail psychiatric Advanced Practice Registered Nurse candidates could be given as a result of the study. This study was the first phase at improving the medical, psychiatric and addiction care provided to detainees at the jail. In future phases of this study more valid and reliable assessment tools and treatment planning aimed at reduced recidivism rates will be established. Future phases will build on the lessons learned here about working with security staff, collaborating with experienced researchers in the community, and seeking advice from the Department of Justice recognized experts.

Since 2008, the United States (USA) has resettled thousands of Bhutanese refugees, providing brief financial support and pathways to citizenship. Despite the efforts of governing bodies and voluntary agencies which facilitate resettlement, many refugees struggle with adapting to the vastly different lifestyle, economy, language and social structures. In particular, effectively addressing psychological needs of this population is a challenge for service providers operating within an expensive health care system based on Western constructs of mental health. In response to this challenge, refugee resettlement agencies throughout the country use community gardens to promote psychological healing, self-sufficiency, community engagement, and a return of human dignity. Though success of these programs is being shared in the media, there has yet to be empirical data examining their impact. The current study tested whether Bhutanese refugee engagement in a community garden impacts symptoms of depression, anxiety, PTSD and somatic complaints. The study also investigated whether community gardening is associated with perceptions of social support and adjustment to life in the United States. Quantitative and qualitative data was collected from 50 adult Bhutanese refugees in Fort Worth, Texas. Gardening was significantly related to increased social support overall, a key factor in overall functionality within communal cultures; and specifically perceived tangible support was increased. A significant effect of gardening was also found for adjustment. Although a significant effect was not found for psychological and somatic symptoms, there is still evidence of effects on somatic complaints. Varying results from quantitative and qualitative data warrant further investigation into the nuanced work of clinical research and advocacy with refugee populations.

This thesis examined if a combination of variables would yield a higher recall for printed news than previously recorded. Some subjects, after reading a printed news story were exposed to rehearsal (a discussion), a cue (aided recall), a combination of both, and neither variable. It was hypothesized that subjects exposed to a combination of rehearsal an a cue would record the highest net recall, or hypermnesia effect, over subsequent testing and that subjects exposed to either one would record higher net recall than those exposed to neither variable.Subjects exposed to rehearsal and/or a cue did not record a higher net recall, gross recall, or correctly recalled details for the printed news story than those who were not exposed. However, rehearsal and a cue were found to have a significant effect on the amount of errors made by subjects: those exposed to a cue made significantly less errors on the recall test. Suggestions for future research include increasing rehearsal time and using a stronger episodic cue than employed in this study.

The process of social problem-solving appears to consist of several general stages including problem orientation, problem definition, generation of alternatives, and decision making. A significant number of studies have found that depressed individuals have a more negative orientation towards their problems and generate a smaller number of less effective solutions on pencil-and-paper measures. Rumination in response to a dysphoric mood has been found to exacerbate feelings of sadness and social problem-solving deficits, while efforts at distraction have been found to reduce or eliminate these effects. To date, nearly all of the research on social problem-solving has utilized pencil-and-paper measures of how individuals feel they would respond to hypothetical problems. The current investigation was designed to evaluate the social problem-solving ability of dysphoric and non-dysphoric participants while talking with a counselor in an analogue counseling interview.More specifically, this study examined the effects of dysphoria and the use of temporary distraction techniques on the social problem-solving ability of 84 female undergraduate students. A structured problem-solving interview and corresponding coding system was designed to measure D'Zurilla and Goldfried's (1971) stages of problem-solving. The coding system yielded high levels of internal consistency, content validity, and construct validity. Forty-one dysphoric females and 43 non-dysphoric females were randomly assigned to either a rumination or distraction task. Dysphoric participants in the rumination condition reported increased levels of sadness, whereas dysphoric participants in the distraction condition reported decreased levels of sadness. After engaging in the rumination or distraction task, each participant was asked to talk with a female counselor during a structured problem-solving interview. Results of a 2 (dysphoric/non-dysphoric) X 2 (rumination/distraction) MANOVA yielded a non-significant interaction effect and a significant difference for the main effect of dysphoria on participants' ratings of problem severity and confidence in solving the problem. Dysphoric participants, whether given a rumination or distraction task, reported a more negative orientation towards their problems, but did not display any deficits in their ability to describe the problem, generate effective solutions, or choose an effective solution. The current findings underscore the need for more naturalistic, behavioral measurements of problem-solving ability and call into question the assumption that depressed individuals exhibit social problem-solving deficits.

The purpose of this study was to examine the influence of self-efficacy on attentional deployment in a coincidence timing (CT) task.
Hypotheses stating that high self-efficacy would incur less performance error than low self-efficacy and that increasing task difficulty, or stimulus speed, would increase CT error as a result of decreased reserve attentional capacity were tested. MANOVA procedures were used to compare CT error scores over three experimental conditions, two levels of task condition (single/dual) and two speeds (15/25 mph). Alpha was set at the.10 probability level for all statistical comparisons.
As predicted, the positive feedback group reported significantly higher levels of self-efficacy than did the control and negative feedback groups, who were statistically similar in self-efficacy. Less variable, absolute, and total error was incurred by positive feedback than by the negative and no feedback treatments. A significant difference between the negative and no feedback groups was also noted in reserve attentional capacity.

Shared characteristics and predictors of psychological distress are beginning to be identified in research on women seeking genetic testing for BRCA1 and BRCA2 gene mutations. This study further explored patterns of psychological distress for 51 community women waiting to receive such genetic test results. There was no significant relationship between psychological distress and family cancer history, personal cancer history, social support networks, and family environment. Women in this sample tended to rely more on females and relatives for support than males and friends. Social support satisfaction was not related to gender or number of relatives providing support. Thirty-four of the 36 women classified on the family environment type were from Personal Growth-Oriented families. Comparisons with normal and distressed family means revealed increased cohesion and expressiveness with decreased conflict, indicative of supportive family environments. Limitations and implications are discussed.

[Truncated abstract] Background: A review of the literature indicated there was a need for more long-term randomised controlled studies on the effects of BRCA counselling/testing on high risk women, including improved strategies for risk communication. Reviews have also shown women are confused about the significance of inconclusive or non informative results with a need for more research in this area. Aims: The general aim of this study was to evaluate the impact of breast cancer genetic counselling on psychological distress levels, perception of risk, genetic knowledge and understanding of BRCA testing/test results in a cohort of 207 women from high risk breast cancer families who were referred for genetic counselling in Perth during the period 1997 to 2001. Short- and long-term impact of BRCA genetic counselling/testing was determined in women with and without cancer in a randomised controlled trial as part of which women were randomised to either receive immediate versus delayed genetic counselling. This included family communication patterns before BRCA testing, anticipated outcomes of testing on oneself and family including intentions for result disclosure. Comprehension of index and predictive BRCA testing with possible results was assessed both in the short- and the long-term and understanding of individual or family BRCA test results was evaluated at long-term. The effect of genetic counselling on breast cancer risk perception in unaffected women was evaluated. This study considered a theoretical framework of educational learning theories to provide a basis for risk communication with possible relevance for future research. ... Only 25% of the original study population (52/207) reported BRCA results and women's understanding of results is concerning. Key findings were: 1. The majority of affected women received an inconclusive result. 2. Out of twelve unaffected women who reported results, seven were inconclusive which are not congruent with predictive testing. This implies that these women did not understand their test result. 3. A minority of untested relatives did not know whether a family mutation had or had not been found in their tested family member or what their actual test result was. This implies either a lack of disclosure or that woman did not understand the rationale for and significance of testing for a family mutation. 4. Three relatives did not understand a positive result was a mutation. Conclusion: The implication of this research for breast cancer counselling and testing services is that women who wait for counselling are no worse off in terms of short- or long-term general psychological distress than women who receive the intervention early. There is a suggestion that unaffected women without the disease found counselling more advantageous than affected women. The meaning of BRCA results as reported by women is concerning particularly women's understanding of negative and inconclusive results and further research is needed in this area. Too much information presented at counselling may affect women's comprehension of risk, BRCA testing and future test results and further research is required to evaluate the effects of information overload.

The purpose of this investigation was to compare associative and dissociative psychological strategies of attentional focus for their effects on self - report ratings of perceived exertion (RPE), and heart rate during endurance exercise. Trained cyclists (n = 7) performed three 60 minute experimental rides on a bicycle ergometer which consisted of an association ride (attention focused on heart rate feedback), a dissociation ride (attention focused on responding to a cue word on a videotape), and a control condition ride in which focus of attention was not purposely manipulated. Results indicated that the deliberate application of a cognitive strategy designed to encourage an individual to associate or dissociate did not differentially effect either actual efficiency (heart rate) or perception of exercise intensity (RPE scores). Overall, it was concluded that there was a trend for the dissociation condition to result in higher RPE scores than the association condition or control condition.

The Contact Hypothesis (Amir, 1969) suggests that attitudes toward a minority group can be modified. However, attitudinal change depends upon the nature of the contact. The main purpose of this study was to examine the effect of the B.C. Wheelchair Sports Demonstration Team Presentation on attitudes of junior high school students toward physically disabled persons This was measured by the Attitudes Towards Disabled Persons Scale (ATDP) (Yuker et al., 1960) and the Modified Issues in Disability Scale (MIDS) (Makas, 1985). The treatment consisted of a one hour structured program that included contact with physically disabled persons and information about their disabilities. One hundred and thirty-one able-bodied students (ages 13-15) from four junior high schools in two British Columbia school districts participated in this study. Students from one school in each district attended the British Columbia Wheelchair Sports Demonstration Team Presentation. Students from the other school did not attend and were assigned to the control group. This research used a one-group pretest-posttest design with a posttest-only control group as a follow-up . four weeks after the treatment. Subjects in the experimental group completed the ATDP prior to and immediately after the treatment. As a result of the high correlation (r=.91) between the MIDS and ATDP with a prior sample of 15 year old students, both experimental and control groups completed only the MIDS four weeks after the treatment. All subjects completed the Social History Questionnaire (SHQ) (Makas, 1989) on each occasion. The SHQ gathered information on gender, birth date, place of residence and prior contact with physically disabled persons. A t-test for dependent samples comparing differences between pre- and posttest MIDS scores of the experimental group was not significant (p=.112 for a 2-tailed test). However, in the follow-up portion of the study, an analysis of variance of the ATDP found a significant difference between the experimental and control groups (p=.007). There were no significant interactions of gender, age or previous contact with treatment. The findings of this study show that able-bodied students' attitudes can be positively modified with an information plus contact program. Although the modification was not immediate, a delayed effect occurred. Three focuses of further investigations might include the following: a need for attitude modification research related to disabled persons particularly in the junior high school age group; continued reliability and validity testing of the MIDS, and a refinement of the SHQ to more accurately assess prior contact with disabled persons.

A descriptive study was conducted with the purpose of refining the Sexual Adjustment Questionnaire (SAQ) and further establishing reliability and validity. Twelve women receiving treatment for breast cancer and 22 women who were at least three months post-treatment for breast cancer voluntarily participated in the research study. Each was administered the Sexual Adjustment Questionnaire. Findings of the study revealed that the SAQ in its entirety was internally consistent. Repatterning of sexual behavior subsequent to having breast cancer did not occur in either group of women. Both the women receiving cancer treatment and those post-treatment experienced a noticeable change in their sexual behavior since having cancer.

The purpose of this research is to develop and empirically test a conceptual framework for examining the effects of advertising exposure on consumer memory so as to better understand the information processing of advertisements. Patterns and levels of performance on various tests of memory for different advertisement components are interpreted within the framework of a memory model adapted from the well-known SAM model in psychology. Predictions are made regarding the effects on recall, recognition, and indirect test performance of an ad's execution strength and relevance to the main message elements, and elaboration (semantic versus nondirected). The general diagnostic procedures are illustrated in a study of humor in advertising. Subjects viewed print ads with variations in the humorous execution's strength and relevance to the brand claims either without explicit instructions to elaborate or with a task requiring semantic elaboration of the links between the humor and the brand claims. Subsequently they completed a (direct) recognition or recall task, or an indirect test of memory for various ad components. The results, though not entirely systematic, show that memory for the brand name and brand claim components vary as a function of stimulus characteristics and the processing operations at encoding. Second, the findings show that the ad components may facilitate or interfere with each other. High levels of attention to one ad component may lead to lower memory performance on other components. Third, this research shows how a theory-based set of comparisons of memory test performance may be used to identify the locus of effects, viz., at encoding or at retrieval. Memory failures due to lack of encoding attention to the ad are distinguished from the inability to retrieve the encoded information later. Finally, the study demonstrates the use of indirect tasks in testing advertising effects that implicate implicit retrieval processes from memory. The patterns of parallel versus dissociated performance on traditional direct versus indirect tests offer insights into various types of advertising effects on memory. The academic and managerial implications of the findings are discussed.

The present study attempts to further define the neuropsychological characteristics associated with mild, moderate, and severe closed head injuries (CHI). The Dean-Woodcock Neuropsychological Assessment System (D-WNAS), a new neuropsychological battery, was administered to 119 CHI patients. The scores of the cognitive portion of the D-WNAS were then analyzed via cluster analysis in an attempt to further delineate neuropsychological impairment into more specific classifications occurring within types of brain trauma.Results suggested that the cognitive portion of the D-WNAS was effective in separating 4 subtypes within CHI, which are best interpreted as "profiles" or characteristics associated with "levels" of impairment. These levels of impairment were characterized by distinctly different subtest profiles, and were labeled as mild/high functioning, mild, moderate, and severe. The highest performing group, mild/high functioning, showed no neuropsychological deficits. The most severely impaired group was characterized by many deficits in short-term memory, visual stimuli, new learning, processing speed, visual-spatial abilities, abstract reasoning, attention/concentration, and remote memory tasks. A multivariate analysis showed that educational level was significant in differentiating between the subtypes and suggested that, depending on the severity of injury, educational level might also protect individuals from obtaining a poorer prognosis.From this investigation, the cognitive portion of the D-WNAS appears to offer valuable utility in identifying CHI patients and in further classifying their varied neuropsychological characteristics. Implications for diagnosing and differentiating between different levels or profiles of CHI was discussed.

The self concept is a critical variable in the overall development and functioning of hearing impaired pupils, yet the findings of research studies indicate that pupils may have difficulty forming a realistic, positive self concept. The consequences of the hearing loss appear to contribute to lowered self-esteem. The accumulated effect of unresolved psychosocial developmental stages may increase the probability of identity confusion in adolescence. The results of research on the self concept of the hearing impaired has been inconclusive and difficult to interpret partly due to the use of inappropriate self concept scales. There is a need for a relevant test which assesses pupils' strengths and weaknesses in dimensions of the self concept. In this dissertation, the 'Self Concept Scale for the Hearing Impaired' (SSHI) is developed with the purpose of designing an appropriate self concept scale specifically for use on hearing impaired pupils between the ages of 11 and 19 years. During the construction and administration of the SSHI, an attempt was made to control for confounding variables known to influence responses of pupils and to distort scores obtained. The SSHI was constructed primarily according to the homogenous-keying approach. Test-retest reliability coefficients were computed over a 4 to 5 week period for 198 pupils in three schools for the hearing impaired in the Western Cape.

The purpose of this study was to examine possible differences between the field and laboratory ratings of perceived exertion (RPE) when the performance and physiological measures for the two conditions were equated. Furthermore, the interactive effects of local, central and overall RPE were examined. Finally, the question of the potential effects of attitudes on RPE was addressed. Eleven well-conditioned adult male marathon runners voluntarily participated in the study. After a period of treadmill habituation, biographical and anthropometric data were collected. This was followed by a VO₂ max test and a speed-matching session at 70% of VO₂ max to determine overground running speed at 3.8% and 7. 5% grade. Subjects then completed an attitudinal questionnaire and ran 4km overground. Finally, the above test was repeated on the treadmill, with the gradient and running speed of the overground condition being replicated. Physiological measures and differentiated RPE were obtained during the final two sessions. There were no physical environmental, task characteristic or performance differences between the overground and treadmill conditions. No heart rate or VO₂ differences were observed between the two conditions, but VE was significantly elevated in the laboratory. Local and overall RPE were significantly higher in the laboratory than in the field, but there was no difference for central RPE. Attitudes were more favourable towards the field than towards the laboratory work task. The results suggest that neither heart rate nor VO₂ are major factors directly influencing the perception of exertion. VE however appears to be a potent central signal mediating RPE. The results also indicate that local factors play a more important role in the perception of exertion than was previously thought. Attitudes towards a work task could possibly mediate the self-reports of exertion. The findings of this study also suggest that RPE are influenced by cognition to a large degree. Finally, environmental cues, or the ambience of a particular working environment, can exert a substantial influence on RPE. Direct perceptual translations from laboratory to field situations may therefore be invalid.

Due to limited research in the field testing of youth sport, specifically with regard to females, this project was delimited to the examination of the responses of youth participants in relation to the nature of the sport, when participating under conditions of competitive stress. It further attempted to elucidate gender related differences within these responses. Forty four male and female subjects aged 15 - 19 years volunteered to participate in this study; all pupils were First team members who competed in a variety of team and individual sports. Subjects participated in a battery of psychological, physiological and performance tests before and after competing in a practice session and during competitive league matches. The data were statistically analyzed for the various parameters under investigation. The results of the Sport Competition Anxiety Test indicated that the females, and the male team players had the highest competitive anxiety traits (CTA). The Task and Ego Orientation in Sport Questionnaire scores showed that most subjects have a general dominance of task orientation to sport. The results of the Physical Self-Perception Profile revealed that the females' poorer perception of their physical was not as substantial as their difference in CTA compared to males. Team participants, particularly the males, had a poorer self-image than individual sport counterparts. Elevated heart rate responses were observed prior to performing in a competitive ambience, with significant increases in team, rather than individual, players. The Evaluation of Task Demands revealed that team players, especially the females, perceived the match demands as significantly higher than the individual athletes. No significant differences were observed in the players' Evaluation of Perceived Strain. Neither were any significant differences observed in the players' ratings of their performance. In conclusion, although differences appear to exist between male and female responses within a competitive ambience, the magnitude of difference was far more notable between team and individual responses to competitive stress, particularly for competitive matches as opposed to practice sessions.

The purpose of the study was to examine the effects of mental practice on the shooting accuracy performance of male water polo players at three skill levels. Thirty-six right handed athletes from the Quebec League, assigned by experienced coaches to novice, intermediate and elite groups according to their overall water polo playing ability, served as subjects. They were tested on shooting accuracy by the average score of ten shots in the beginning of the study, after a two-week mental practice treatment, and after a one-week break with no treatment.
A 3 way ANOVA with repeated measures on the last factor was conducted on the shooting accuracy scores. Those who received the mental practice program had significantly higher post-treatment scores than their control group counterparts who had received a relaxation training program during the treatment period. As noted above, the experimental group improved significantly from Pre to Post1 test-time, and there was no change in performance between the two Post-tests. There was no significant difference in shooting performance between Intermediate and Elite skill groups but both of them scored significantly better than the Novice group.

The purpose of the study was to investigate the perceived anxiety experienced by coronary care nurses working eight- and 12-hour work shifts. It was hypothesized that length of shift work affects the before- and after-shift anxiety for nurses working eight- or 12-hour work shifts. Anxiety differences between the eight- and 12-hour work shifts were examined as well as differences between the before- and after-shift anxiety for each length of shift.Thirty-two (32) coronary care nurses from a general medical and surgical hospital in the Midwest volunteered to participate in the research. The sample consisted of all females (18 Registered Nurses, nine Licensed Practical Nurses, three charge nurses, a supervisory nurse, and a rehabilitation nurse). The nurses had voluntarily selected the eight- or 12-hour length of shift work and understood that they would be committed towork that shift for one year. Twelve nurses worked the eight-hour shift; 20 nurses chose the new 12-hour shift.The State Anxiety Inventory (SAI) was used to measure the nurses' before- and after-shift anxiety. Baseline data were collected from the nurses prior to the initiation of the 12-hour shift. The Box-Jenkins Time Series Analysis was used to analyze the daily before- and after-shift anxiety scores and to establish a forecasted trend for both the eight- and 12-hour shifts.The first finding was that the before-shift anxiety scores for the eight-hour workers declined, while the anxiety scores for the 12-hour workers increased, following the implementation of the 12-hour shift. The same trend was forecast for the after-shift anxiety scores. The eight-hour nurses' after-shift anxiety scores declined while the 12-hour nurses' anxiety scores increased. A transfer function was conducted for both the eight-hour and 12-hour before- and after-shift anxiety scores. No predictive trend could be established for the eight-hour anxiety scores; however, the 12-hour after-shift anxiety scores were found to be consistently higher than before-shift anxiety scores.

The purpose of the present study is to extend past outcome-dependent models of Sport Competition Anxiety (SCA) to include attribution theory as an appraisal process of past performance outcome. It was hypothesized that unstable causal attributions for past unexpected performances would lead to uncertain expectations of future performance and subsequent SCA. Sixty-three male subjects were assessed for initial expectations of how they would perform in a cycling task, i.e., high and low, in which each subject received false feedback about his performance (success or failure). After completing the task, subjects completed questionnaires assessing the discrepancy between expected and actual outcome, attributions for past performance (Causal Dimension Scale), expectation for future performance, and the Competitive State Anxiety Inventory-2 which measures state cognitive and somatic anxiety and state self-confidence. Contrary to predictions, results indicated that attribution did not mediate SCA, but rather attributions were made systematically in response to success and failure and not unexpected outcome. However, path analysis carried out on a modified model of SCA that includes outcome and expectations of future performance, indicated that somatic anxiety and state self-confidence are mediated by expectation of future success. The findings are discussed in terms of attribution theory and other cognitive constructs (e.g., self-schemata and efficacy expectations) that might have an impact on attributional patterns that lead to performance expectations and SCA. It is noted that because only male subjects were used, generalizability to female competitors may not be appropriate due to differences in sport socialization.

Background: Motivation plays a vital role in dental students' learning experience and wellbeing. Self-determination theory differentiates between autonomous and controlled motivation and amotivation, where autonomous motivation corresponds to the most selfdetermined form of regulation. Previous research has found that several social educational factors, mediated by students' satisfaction of their basic psychological needs of feeling autonomous, competent and related to important others, predicts autonomous motivation. In turn, autonomous motivation leads to more positive educational outcomes compared to controlled motivation or amotivation. So far, however, few studies have investigated the process of motivation in health professions education from the perspective of the Selfdetermination Theory. A systematic review was conducted within this thesis, identifying determinants, such as an autonomy supportive learning climate and feedback, that predicted students' autonomous motivation. No studies were found that tested mediation effects between determinants and motivation. In turn, students' self-determined motivation was found to predict different affective, behavioural and cognitive outcomes. These studies, however, came mainly from medical education. Despite its relevance for students' development, very little is known about the process of motivation in dental students. This indicates a need to understand its various aspects, which may lead to evidence-based interventions to foster students optimal functioning. Purpose: To test a model of academic motivation in dental education by analysing the associations between autonomy-support and quantity and quality of feedback, as determinants, and self-determined motivation, mediated by students' basic psychological needs satisfaction. This, followed by testing the associations between self-determined motivation and the behavioural outcomes of deep and surface study strategies and academic performance, and the affective outcomes of vitality and self-esteem. Finally, we aimed to test whether the model worked different for female and male students, and by year of curriculum. Methods: We conducted a correlational cross-sectional survey study at the dental school of the University San Sebastian in Chile. All dental students from year 1 to 6 were invited to participate and to answer a questionnaire package containing demographic data and previously validated self-reported instruments. Data on academic performance were obtained from the administrative department. Data analysis involved five phases. First, internal consistency of all measures was assessed by means of Cronbach alpha. Second, descriptive and group comparisons were computed by means of independent t-test to assess gender differences and MANOVA to assess year-of-curriculum differences. Third, bivariate correlations were assessed amongst all measures. Fourth, mediation was tested through a series of regression analyses. Finally, the entire model was assessed by means of structured equation modelling, for the overall student sample as well as for the subgroups of females and males and different years of study. Data were analysed with the PASW and AMOS software. Results: A total of 924 students (90.2% response rate) agreed to participate and completed the questionnaires. Cronbach's alpha values of all instruments ranged from .641 to .912. Students' autonomous motivation for attending university was higher than controlled motivation and amotivation, showing an overall self-determined profile. Females endorsed higher than men both autonomous and controlled motivation, while men endorsed amotivation higher. The overall motivation profile, however, did not show significant gender differences. Across the six years, students showed an overall self-determined profile, in which autonomous motivation decreased when transitioning to clinical years, to rise again in the final year. The contrary was found for students' amotivation scores, while controlled motivation declined as they entered clinical-based years. Bivariate correlations showed that both determinants were positively correlated with students' basic psychological needs satisfaction and with autonomous motivation. In turn, the latter was positively associated with behavioural and affective outcomes. All these associations showed a decreasingly positive correlation from autonomous motivation to amotivation. Mediation regression analyses showed both determinants predicting dental students' autonomous motivation, however, this influence was not direct, it was mediated by students' perceptions of the satisfaction of their basic psychological needs. Finally, structured equation modelling indicated that the data fitted the model well, and showed both determinants positively predicting students' satisfaction of their basic psychological needs, which positively influenced autonomous motivation over controlled motivation. In turn, the gradual shift from controlled to autonomous motivation positively predicted affective and behavioural outcomes. Moreover, the associations followed a similar pattern, with minor deviations, when tested by gender and by year of study. Discussion and conclusion: In the context of this research, dental students' autonomous motivation was indirectly predicted by the social educational factors of teachers' autonomysupport and quantity and quality of feedback, being mediated by students' satisfaction of their basic psychological needs. Students' acting out of autonomous motivation showed enhanced deep study strategies and better academic performance, experienced higher vitality and self-esteem, and showed lower surface study strategies. This suggests that autonomous motivation leads to important outcomes, decreasing from controlled motivation to amotivation. Whilst students in different years of study showed an autonomous motivation profile, there were important differences that showed that students' transition from basic/preclinical to clinical years influenced their motivation and should therefore be taken into account when planning interventions to enhance students' motivation. Results are discussed in light of self-determination theory and considering its implications on curriculum development, teaching and learning, clinical training, assessment, faculty development, peer-assisted-learning and dentist-patient relationship. Significance: This is the first study, in health professions education, to test a Selfdetermination theory-based model including determinants, mediators, motivation and outcomes. This research also expands to dental education the study of motivation based on an empirically verified psychological theory. The results provide strong support for the Selfdetermination theory of motivation in dental education and provide acceptable evidence that the quality of motivation and satisfying students' psychological needs are important in determining positive educational outcomes amongst dental students. Therefore, many successes and failures in a number of elements of dental and health professions education may be understood through the lens of this theory. As such, efforts should be made in various aspects of dental education to support learners' sense of autonomy, competence and relatedness, which may have an extensive influence on dental education and on students' wellbeing. Future research should confirm or refute our results in other dental education settings.

An understanding of factors that enhance empathic parenting behaviors is of considerable importance to the study of child development and to the development of parenting interventions to promote child adjustment. Moreover, gaining a better understanding of the factors that predict empathic parenting with older children is of interest since most research examining parental empathy focuses on infants. These were the goals of the current study. Guided by Belsky's 1984 process model of the determinants of parenting that impact child development, an expanded model of the determinants of parenting is proposed that includes various parent, child, and contextual factors of influence. Using data from a community sample, a partial least squares path analysis approach was employed to test the model's strength in predicting empathically attuned parenting with children ages 5 to 10 years and, ultimately, the child's psychoemotional functioning. Results support the expanded model; however, a reduced model was found to be superior and revealed unique relationships between the determinants of parenting. Specifically, a parent's psychoemotional functioning and childrearing beliefs and attitudes were found to be critical to the parent's ability to engage in empathic parenting behaviors. Other parent factors such as the parent's developmental history of abuse, maladaptive personality traits, and age, along with contextual factors and child characteristics, were found to influence parenting only indirectly through their impact on the parent's level of psychoemotional distress or childrearing beliefs and attitudes. Ultimately, the current findings support Belsky's claim that parent factors are the strongest predictors of empathic parenting. Implications of these findings are many. The results highlight the importance of assessing a parent's childrearing beliefs and attitudes and level of distress in conjunction with characteristics of the child when a family comes in for treatment. Moreover, the results identify many points of intervention to stopping the cycle of abuse.

There is little consensus in the social-cognitive literature concerning the way in which prejudice and stereotyping are related, though a number of explanatory models have been proposed. The present research program empirically examines one recent model; Lepore and Brown's Associative Strength Model (ASM: 1997; 1999; 2002). The main premise of the ASM is that differential endorsement of stereotypic content leads to individual variation in the content that is automatically activated upon categorisation. Specifically, it predicts that high-prejudice people automatically activate negative stereotypic traits, and low-prejudice people automatically activate positive stereotypic traits. The current research used a primed lexical decision task to examine prejudicelinked differences in automatic stereotype activation. In addition, an impression formation task based on that of Lepore and Brown was included to measure stereotype application. Experiments 1A and 1B attempted to evaluate the predictions of the ASM using the category and stereotype of Asians. However, neither experiment was able to demonstrate a priming effect, prejudice-linked or otherwise, using this social category. Experiments 2 and 3, in contrast, successfully induced stereotype activation using the category of gay men. Furthermore, results were consistent with the predictions of the ASM. After priming with the category of gay men, high-prejudice participants exhibited greater activation of negative stereotypic traits and low-prejudice participants exhibited greater activation of positive stereotypic traits. However, parallel patterns of stereotype application were not found in the impression formation task, with participants forming positive impressions, regardless of prejudice. Experiment 4 used an honesty manipulation to investigate the possibility that self-presentational concerns were responsible for the discrepancies between stereotype activation and application. Consistent with this argument, Experiment 4 found prejudice-linked patterns of stereotype application that mirrored the patterns of stereotype activation when self-presentation concerns were reduced. When instructed to be honest, high-prejudice participants in the gay prime condition formed negative impressions and low-prejudice participants in the gay prime condition formed positive impressions. The current program of research provides the first direct empirical support for the predictions of the Associative Strength Model concerning stereotype activation. In addition, new questions have been raised that future research should seek to explore.

ENGLISH ABSTRACT: Pregnancy is a vulnerable time in settings such as sub-Saharan Africa, and is associated with exposure to a multitude of physiological, social and psychological risks. High HIV prevalence, and the fact that many women will test for HIV for the first time during their pregnancy, has raised concern about women‘s psychological health during pregnancy. Depression during the antenatal period is of public health concern as it has been shown to be associated with poorer foetal and delivery outcomes, risky behaviours, and poorer uptake of antenatal care. Antenatal depression is a predictor of postnatal depression, and postnatal depression has been associated with poor maternal sensitivity and attachment in mothers which is known to result in increased behavioural and developmental difficulties in children. The aim of this research was to provide a clear, in depth and culturally sensitive understanding of the manifestation of depression in pregnant women in a rural area with high HIV prevalence in South Africa. The research method included a diagnostic assessment of depression in 109 women in their third trimester of pregnancy, and an in-depth qualitative examination of the contextual framework within which HIV testing and depression are experienced with a sub-sample of 56 women. The quantitative results demonstrated that the prevalence of antenatal depression was high (46.7%), with close to half of the women being diagnosed with depression. Presentations of depression most frequently included disturbances in mood, loss of interest and suicide ideation. Symptoms which overlap with common side effects of pregnancy such as loss of energy and weight change did not result in an overestimation of depression. Likewise, very little evidence of the somatisation of depression, or particular cultural barriers to the diagnosis of depression based on DSM-IV criteria was found. Rates of suicide ideation were high and equally common among HIV positive as HIV negative women. Factors significantly associated with depression included living within a family homestead, access to a regular source of income and practical support from a partner. Both income and partner support had a negative association with depression. Living away from a family or parental home had a positive association with depression. The results showed that the Edinburgh Postnatal Depression Scale (EPDS) was effective in identifying depression and that a shorter three item version was as effective as longer versions. A positive score for depressed mood on the EPDS was significantly associated with HIV, suggesting that the EPDS is a good screening tool for elevated psychological risks among HIV positive women post HIV testing. Qualitative results showed that having an unsupportive partner and the occurrence of relationship or familial conflict played an important role in the development of emotional distress during pregnancy and resulted in a high number of unwanted pregnancies. Partner and familial conflict was intertwined with cultural practices which govern the acceptability of childbearing among unmarried women and the social recognition of partnerships and paternal responsibilities. Testing for HIV was considered a stressful life event for all women regardless of their HIV status and was a particularly negative life event for women who tested HIV positive or for women who had concerns over partner infidelity. Disclosure among HIV positive women frequently lead to increased partnership conflict. Qualitative findings suggested that depression and emotional distress after HIV testing did interfere with women‘s ability to engage with prevention messages. Women who were coping well with learning their HIV positive status had high levels of family disclosure and subsequent family support in common. The implication of this research is that it is important that public health programmes screen for depression among childbearing women. These data suggests that a shorter three item version of the EPDS along with screening for partner and family support or conflict would effectively detect most women at high risk for depression. Likewise, public health interventions for women with depression which are implemented in primary health care facilities and in isolation of the partnership and familial context within which depression occurs are not likely to be effective. Further research is needed to establish the precise prevalence of antenatal and postnatal depression in women at high risk for HIV; to validate the effectiveness of a shorter screening tool in resource limited settings; and to establish risk and protective factors, and trimester specific risks which could inform the design of cost effective interventions in poorly resourced settings.
AFRIKAANSE OPSOMMING: Swangerskap in Afrika, suid van die Sahara, is ʼn kwesbare tydperk met blootstelling aan ʼn menigte fisiologiese, sosiale en sielkundige risiko‘s. Die hoë voorkoms van HIV en die feit dat baie vrouens gedurende swangerskap vir die eerste keer vir HIV wil toets, het ‗n besorgdheid oor vrouens se sielkundige gesondheid gedurende swangerskap laat ontstaan. Depressie gedurende die voorgeboortelike periode is van belang vir publieke gesondheid, want daar is bewyse wat dui op ‗n verband tussen depressie en swakker fetale en geboorte resultate, riskante gedrag en verminderde gebruik van voorgeboortelike sorg . Voorgeboortelike depressie is ʼn indikasie van moontlike nageboortelike depressie en nageboortelike depressie word geassosieer met swak moederlike sensitiwiteit en die gebrekkige vorming van ‗n band tussen moeder en kind; wat reeds bewys is om te lei tot verhoogde gedrags- en ontwikkelingsprobleme in kinders. Die doel van hierdie navorsing was om ʼn duidelike, indiepte en kulturele-sensitiewe begrip van die manifestasie van depressie in swanger vroue in ʼn landelike omgewing met hoë HIV voorkoms in Suid Afrika te verkry. Die navorsingsmetode sluit in ʼn simptomatiese beraming van depressie by 109 vroue in hul derde trimester van swangerskap en ʼn indiepte kwalitatiewe ondersoek na die kontekstuele raamwerk waarbinne HIV toetse en depressie ondervind word met ʼn sub-steekproef van 56 vrouens. Die bevinding was dat die voorkoms van voorgeboortelike depressie hoog was, 46.7 %, met feitlik die helfte van die vrouens wat met depressie gediagnoseer is. In die meeste gevalle het die voorkoms van depressie gepaard gegaan met ʼn verandering in gemoedstoestand, ʼn verlies aan belangstelling en selfmoordgedagtes. Simptome wat ooreenstem met algemene newe-effekte van swangerskap, soos verlies aan energie en verandering in gewig, het nie bygedra tot ʼn oorberekening van depressie nie. Soortgelyk is baie min bewyse gevind dat somatosasie van depressie, of spesifieke kulturele grense, tot die diagnose van depressie gebaseer op DSM-IVkriteria bydra. Die oorweging van selfmoord was hoog en algemeen tussen beide HIV-positiewe en HIV-negatiewe vouens. Faktore wat aansienlik met depressie geassosieer word, sluit in om in ʼn familiegroep te bly, toegang tot ʼn vaste bron van inkomste en die praktiese ondersteuning van ʼn lewensmaat. Beide inkomste en die ondersteuning van ʼn lewensmaat het ʼn negatiewe verbintenis met depressive. Om nie by familie of in ʼn ouerhuis te bly nie het ʼn positiewe assosiasie met depressive. Alhoewel HIV-status verband hou met depressie, was dit nie uitermate die geval nie, alhoewel daar ʼn gebrek aan statistiese kragdoeltreffendheid was om die effek van HIV vas te stel, gegee die beperkte grootte van die steekproef. Die resultate het getoon dat die EPDS graderingsinstrument effektief was om depressie te identifiseer en dat ʼn korter driepunt weergawe daarvan net so effektief was soos die langer weergawe. ʼn Positiewe telling vir ʼn depressiewe gemoedstoestand op die EPDS het ʼn betekenisvolle assosiasie met HIV en dui daarop dat die EPDS ʼn goeie graderingsinstrument is vir verhoogde sielkundige risiko by HIV-positiewe vrouens, selfs al is HIV-positiewe vrouens in dié steekproef statistieksgewys nie meer geneig tot depressie as HIV-negatiewe vrouens nie. Kwalitatiewe resultate toon dat ʼn lewensmaat wat nie ondersteunend is nie en die voorkoms van verhoudings- of familiekonflik ʼn belangrike rol speel in die ontwikkeling van emosionele angs gedurende swangerskap en dit het gelei tot ʼn groot aantal ongewenste swangerskappe. Konflik met ʼn lewensmaat en met familie was verweefd met kulturele gebruike wat die aanvaarbaarheid van geboortes onder ongetroude vrouens beheer en die sosiale erkenning van verhoudings en die vader se verantwoordelikhede. ʼn HIV-toets is as ʼn stresvolle lewensgebeurtenis beskou deur alle vroue, ongeag van hulle HIV-status en was ʼn besondere negatiewe lewensgebeurtenis vir vroue wat HIV-positief getoets het of vir vroue wat bekommerd was oor hulle lewensmaats se getrouheid. Onthulling van die HIV-status van positiewe vrouens het gereeld tot verhoogde konflik in verhoudings gelei. Kwalitatiewe bevindings dui daarop dat depressie en emosionele angs na ʼn HIV-toets inmeng met ʼn vrou se vermoë om ag te slaan op voorkomingsboodskappe. Vroue wat die kennis van hulle HIV-positiewe status goed hanteer het, het hoë vlakke van bekendmaking van hulle status en die ondersteuning van hulle familie in gemeen. Die implikasie van die navorsing is dat dit belangrik is vir publieke gesondheidsorgprogramme om te toets vir depressie onder swanger vroue. Die resultate dui daarop dat ʼn korter driepunt weergawe van die EPDS, saam met ʼn ondersoek na die ondersteuning van of konflik met ʼn lewensmaat en familie, effektief kan wees om vroue met ʼn hoë risiko vir depressie te identifiseer. Soortgelyk, publieke gesondheidsingryping in primêre gesondheidsorg fasiliteite vir vroue met depressie wat in isolasie van die lewensmaat en familie konteks, waar depressie voorkom geadministreer word, is onwaarskynlik om te slaag. Bevindings onderskryf die belangrikheid van ondersteuning vir die familie om effektief te kan reageer en herstel van stresvolle faktore soos onbeplande swangerskappe en HIV-diagnose, in ʼn konteks wat swaar deur HIV geaffekteer word, aangesien dit ʼn voorkomende effek op depressie kan hê. Verdere navorsing is nodig om die presiese voorkoms van voorgeboortelike en nageboortelike depressie in vrouens met ʼn hoë blootstelling aan HIV vas te stel; om die sukses van ʼn korter graderingsinstrument in arm omgewings te staaf; en om die risiko en beskermende faktore vas te stel en trimester spesifieke risiko‘s wat die ontwerp van ʼn koste-effektiewe ingryping in gebiede met ontoereikende hulpbronne kan beïnvloed.

Aim. This study aims to investigate self-understanding in young males with high-functioning autism spectrum disorders (ASD) and to determine whether self-understanding is related to social functioning and theory of mind (ToM). In addition, this study aims to examine the characteristics and abilities of young males with high-functioning autism (HFA) and Asperger’s disorder (AD) to determine whether there are significant differences in selfunderstanding and whether self-understanding is related to social functioning and ToM between these two groups. The results have important implications for social skills interventions for young people with ASD. Method. Forty three young males diagnosed with one of the ASD (25 diagnosed with HFA and 18 diagnosed with AD) were compared with 38 TD males. Participants were assessed using the Autism Diagnostic Interview- Revised (ADI-R), the Kaufman Brief Intelligence Test (KBIT), the Vineland Adaptive Behavior Scales (VABS), the Peabody Picture Vocabulary Test- Third Edition (PPVT-III), Damon and Hart’s Self-understanding Interview, and two false-belief ToM tasks. Results. Children with ASD had difficulties recognising and attributing their own mental states and failed to integrate various aspects of the self. Specifically, the ASD group produced fewer self-statements that reflected agency (the awareness and understanding that one is in control of their actions), social aspects of self (such as personality characteristics and group membership) and psychological aspects of self (such as emotions, thoughts and cognitive processes). Instead, children with ASD produced more concrete physical self-statements (such as body characteristics and material possessions). A significant positive relationship was found between selfunderstanding and social functioning for the ASD group. Within the ASD group, the relationship held for the HFA group only. In terms of ToM, children with ASD were less able to correctly answer the second-order false-belief ToM question compared to the TD group. For the ASD group, there was a significant positive correlation between self-understanding and ToM. Within the ASD group, the relationship held for the HFA group only. Conclusions. The results show young males with high-functioning ASD are less aware of their own and others’ mental states perhaps reflecting a general delay in the development of self-understanding and ToM. Furthermore, a more developed self-understanding may translate to improved social functioning and ToM ability for young males with high-functioning ASD. For young males with HFA, self-understanding and ToM may stem from a common underlying cognitive framework. Consequently, treatments aimed at improving self-understanding may simultaneously improve ToM, or vice versa. For individuals with AD there may be a separate cognitive mechanism responsible for self-understanding and another for ToM. Therefore, different interventions may be required; one to improve self-understanding and another to improve the understanding of others’ minds. Overall, these results may assist in the development of practice parameters for social skills training for those with ASD.

The direct effect of spouse presence during graded exercise testing on anxiety and performance has not been previously delineated. Therefore, the purposes of this study were to (a) ascertain if spouse presence during graded exercise testing affects state anxiety or physiological performance variables, and (b) determine differences in psychological status between cardiac patients and healthy adults.

The Marital Interaction Dimension Inventory (MIDI) is an assessment that evaluates marital relationships on seven dimensions; sexuality, self disclosure, emotional affiliation, conflict resolution, power outcome, commitment, and identity. The MIDI provides scores on and individual's actual and desired relationship.

The Index of Receptivity to Tobacco Industry Promotion (IRTIP) is a model that is used by hundreds of articles. The causal claim based on findings from this model is even more pervasive, and has resulted in much of the modern post 1998 tobacco legislation that is still enforced. This thesis tested the link between adolescent receptivity to tobacco industry promotion and susceptibility to smoking. Pierce et al. (1998) reported that they had found a positive and causal association between receptivity and susceptibility by using IRTIP. They claimed that receptivity to tobacco industry promotion was the only significant causal factor affecting adolescent susceptibility to smoking. Exposure to peer and parental smoking was not found to be a significant effect. A review of the literature found that many sections of IRTIP differ from accepted marketing theory on how cigarette advertising and promotions affect adolescent adoption of cigarette smoking. The proxy measures used in IRTIP were shown to diverge from those previously used for measuring the constructs of Attention, Intention, Desire and Action (AIDA) in marketing communications. IRTIP also differs from previous theory by including measures that attempt to quantify the effect of tobacco premiums into a model that was designed to measure the effects of advertising.

ENGLISH ABSTRACT: The ability of organisations to be successful in the current global business environment will ultimately be dependent on their ability to be innovative. However, creativity and innovation will not take place spontaneously in any team setting and will be the result of meticulous planning and implementation efforts on the part of the team’s members. The current global business environment is characterised by constant change and this makes leadership more important than ever before as leaders are considered the drivers of change and ultimately responsible for organisational success. Leaders within organisational team settings have an essential role to fulfil in stimulating and facilitating innovative behaviour in their subordinates. The fact that some leaders manage to successfully stimulate and facilitate innovative behaviour in their subordinates, while others fail to do so, might well be contributed by some to a number of simplistic variables– but this is not the case. The fact that some leaders manage to successfully stimulate and facilitate innovative behaviour in their subordinates can be attributed to the fact that these leaders possess specific competencies based on different sets of knowledge, skills and attitudes. The innovation process consists of four distinct phases (idea generation, idea screening, feasibility and commercialisation) and innovative outcomes for a team will only result if team members successfully progress through each of these four phases. The reality, however, is that the innovation process itself is filled with challenges that will need to be overcome by team members if innovation is to flourish. Accordingly leaders should apply specific sets of knowledge, skills and attitudes during each of the phases in the innovation process to help guide subordinates successfully through the innovation process. It should hence be clear that being aware of the specific leadership competencies that will stimulate and facilitate innovative behaviour in subordinates will be of immense value to any organisation who wishes to act more innovatively. The primary purpose of this study was consequently to design a psychological measurement instrument that would provide a measure of the specific competencies leaders should possess to stimulate and facilitate innovative behaviour in subordinates. This instrument would enable management to customise training and development programmes to meet the specific needs of leaders and hence develop the necessary knowledge, skills and attitudes on their part. A pilot study was conducted with the experimental version of the ILQ to obtain information regarding the psychometric properties of the instrument. Results obtained from the pilot study provided evidence that the ILQ instrument possesses high levels of internal reliability and satisfactory levels of concurrent validity. It can therefore be claimed that the ILQ instrument would serve as a valuable diagnostic tool for organisations who wish to improve their innovative capabilities.
AFRIKAANSE OPSOMMING: Die mate waartoe organisasies suksesvol sal wees in die huidige globale besigheidsomgewing sal bepaal word deur hul vermoë om innoverend op te tree. Dit is belangrik om daarop te let dat kreatiwiteit en innovasie nie spontaan sal plaasvind binne ‘n spankonteks nie, maar eerder die resultaat sal wees van doelbewuste praktyke en gedrag deur spanlede. Die huidige globale besigheidsomgewing word gekenmerk deur konstante verandering en lei daartoe dat leierskap belangriker as ooit geag word vanweë die feit dat leiers beskou word as die dryfkrag vir verandering en verantwoordelik is vir organisasie sukses. Spanleiers in organisasies moet ‘n essensiële rol vervul met betrekking tot die stimulering en fasilitering van innoverende gedrag in hul ondergeskiktes. Die feit dat sommige leiers dit regkry om suksesvol innoverende gedrag in hul ondergeskiktes te stimuleer en te fasiliteer, terwyl ander leiers misluk om dit reg te kry, word deur sommige individue aan ‘n klein aantal eenvoudige veranderlikes toegeskryf – dit is egter nie die geval nie. Die feit dat sommige leiers dit regkry om suksesvol innoverende gedrag in hul ondergeskiktes te stimuleer en te fasiliteer, kan toegeskryf word aan die feit dat hierdie leiers oor sekere bevoegdhede beskik gebaseer op spesifieke stelle kennis, vaardighede en houdings. Die innovasieproses bestaan uit vier onderskeie fases (idee-generering, idee-evaluering, bepaling van uitvoerbaarheid en kommersialisering) en werkspanne sal slegs innoverende uitkomstes behaal indien hulle suksesvol vorder deur elkeen van hierdie vier fases. Die realiteit is egter dat die innovasieproses inherent gevul is met uitdagings wat oorkom sal moet word deur spanlede indien innovasie enigsins sal floreer in die spanne. Dit is dus noodsaaklik dat leiers ‘n spesifieke versameling kennis, vaardighede en houdings sal aanwend om die pogings van ondergeskiktes suksesvol te bestuur deur die verskeie fases van die innovasieproses. Om kennis te dra omtrent die spesifieke leierskap-bevoegdhede – gebaseer op kennis, vaardighede en houdings – wat innoverende gedrag in ondergeskiktes sal stimuleer en fasiliteer, sal van onskatbare waarde wees vir organisasies. Die doel van hierdie studie was gevolglik om ‘n meetinstrument te ontwerp wat die bevoegdhede sal meet waaroor leiers moet beskik indien hulle beoog om suksesvol innoverende gedrag in hul ondergeskiktes te stimuleer en te fasiliteer. ‘n Meetinstrument van hierdie aard sal organisasies en hul bestuur in staat stel om opleiding en ontwikkeling programme nommerpas te maak en sodoende spesifieke bevoegdhede in hul leiers te ontwikkel. ‘n Loodsstudie is vervolgens uitgevoer om inligting rakende die psigometriese eienskappe van die instrument te verkry. Die resultate het getoon dat die ILQ oor hoë vlakke van interne betroubaarheid beskik, asook bevredigende vlakke van samevallende geldigheid. Die aanspraak kan gevolglik gemaak word dat die ILQ as ‘n waardevolle diagnostiese instrument vir enige organisasie sal dien wat beoog om hul innoverende vermoë uit te brei.

The current study investigated the task performance and subjective preference for two color displays with differing image generation technologies, the standard cathode ray tube shadow mask (CRT) display and the newer liquid crystal/cathode ray tube (LC/CRT) display. Six subjects performed three different information processing tasks using each of the two color display technologies and expressed their display preference via evaluation questionnaires. Ambient illumination measurements were obtained to determine preferred conditions for each display. A four-way factorial design was used to collect task performance data and ambient illumination preferences; performance data were collected as errors per unit task quantity for each of the task types. Subjective evaluations consisted of 20 five-interval bipolar adjective scales and a forced choice rating on eight display parameters. An analysis of variance procedure and post-hoc Newman-Keuls analyses were employed in the analyses of the performance and subjective bipolar adjective scale data; the forced choice rating scales were evaluated using the Sign Test. The task performance results indicate that neither display produced better task performance. The subjective data revealed mixed results; while the bipolar adjective scales indicate no differences between the two display technologies, the forced choice rating shows a preference for the LC/CRT display on some display parameters. A significant difference between the two displays was demonstrated for ambient illumination preferences; the LC/CRT was viewed in greater ambient illumination than the CRT display.

The purpose of the study was to determine whether students' timbre preferences in the sixth grade remain stable through the tenth grade. The investigation also examined whether gender, band instruction, or musical home environment makes any difference in influencing the stability of students' timbre preferences from grade six through ten. Students' timbre preferences at the beginning of the study were compared to their preferences four years later. The students' timbre preferences were obtained by employing Gordon's Instrument Timbre Preference Test (ITPT). A questionnaire was also utilized at the conclusion of the study to determine which students had musical home environments and which did not. All sixth grade students enrolled in a single school district took the ITPT. Each student's scores were tallied and ranked in order to determine their timbre preferences; four years later they were retested and their scores were ranked again.

A number of computerised tests have been especially developed to facilitate the medical management of the sports-related concussion. Probably the most widely used of these programmes is the ImPACT test that was developed in the USA and that is registered with the HPCSA for use in the South African context. A recent Afrikaans version of the test served as the basis of the present study with the following objectives: (i) to collect Afrikaans ImPACT normative data on a cohort of Afrikaans first language adolescent rugby players with Model C education for comparison with existing South African English first language adolescent rugby players with Private/Model C schooling, and (ii) to investigate the pre-versus postseason ImPACT neurocognitive test profiles of this cohort of Afrikaans first language adolescent rugby players versus equivalent noncontact sports controls. The results for Part 1 of the study generally demonstrate poorer performance in respect of the Afrikaans cohort, which is understood to be the result of poorer quality of education. The results for Part 2 demonstrated failure of the rugby group to benefit from practice on the ImPACT Visual Motor Speed composite score to the same extent as the control group. It is argued that this apparent cognitive vulnerability in the rugby group is due to lowered cognitive reserve capacity in association with long term exposure to concussive and sub-concussive injury.

The purpose of this study was to determine whether varying levels of computer anxiety have an effect on computer-based testing of United States Air Force technical training students. The first chapter presents an overview of computer-based testing, defines key terms, and identifies questions addressed in the research. The rationale for conducting this study was that little research had been done in this area. The second chapter contains a review of the pertinent literature related to computer-based testing, computer anxiety, test reliability, validity, and gender differences in computer use. Due to the lack understanding concerning any effects of computer anxiety on computer-based testing, this has been a worthwhile topic to explore, and it makes a significant contribution to the training field. The third chapter describes the qualitative research methodology used to conduct the study. The primary methodology was an analysis of variance comparison for groups of individuals who displayed high or low computer anxiety to their respective mean computer-based or paper-based aircraft maintenance knowledge testing scores. The research population consisted of United States Air Force aircraft maintenance craftsmen students attending training at Sheppard Air Force Base, Texas. The fourth chapter details the findings of the study. The findings indicate that there was no significant difference between the groups of students rated with high computer anxiety and low computer anxiety while testing with computers. Additionally, no significant differences were detected while testing alternative hypotheses covering differences between groups of students rated with high computer anxiety and low computer anxiety testing by traditional paper-and pencil methods. Finally, a reference section identifying the literature used in the preparation of this dissertation is also included.

The state of writing abilities throughout the United States presents an urgent issue. Low student achievement in English Language Arts (ELA) exams and standardized English assessments persist (National Center for Education Statistics, 2012), while businesses spend billions of dollars on remedial writing instruction (Dillon, 2008). Technology is increasingly cited as a potential solution to these issues. Evidence for this is limited, as is existing research into the basis of the issues that technology might address. On account of that context, this thesis turns to a basic distinction between digital and non-digital writing: the writing surface and implement, or pen and paper - screen and keyboard. Conceptualizing such artefacts through a view of writing as a way of thinking raises the following question, which is this study's guiding inquiry. Might we use digital implements and surfaces to support the ways of thinking involved in composing written works of semantic cohesion? Building on research into writing as thinking, the study presented in this document analyses how uses of writing surfaces and implements relate to ways of thinking while writing, and which contextual factors influence those relationships. Drawing on a neuro-anthropological approach, the study focuses on the writer's mind as the driver and source of the lived experience of writing. Expert writers, therefore, are considered to be those who exhibit the ways of thinking while writing to which other writers aspire. To examine a range of uses of writing surfaces and implements with reference to expert writers' ways of thinking, the study was conducted in two parts. Part 1involved a content analysis of published interviews with professional writers. This generated a framework through which to conduct in-depth qualitative research with college student writers - part 2. This thesis is as much about thinking while writing as it is about the different tools available for writing. As such, the study refutes the hyperbolic and deterministic claims about technology and writing, and finds that technology is not leading to new ways of thinking while writing. Instead, surfaces and implements available allow writers to change how they practise their ways of thinking while writing. By considering this distinction and developing understandings of the dynamics involved and their implications, writers may begin to realize the potential of technology for writing. Ultimately, this thesis contributes to existing theories on writing through an informed discussion of how to think about implements and surfaces in ways that support writerly thinking, and by offering fresh ways to think about the lived practice of writing.

ENGLISH ABSTRACT: The South African health care system is tormented by various challenges ranging from income inequalities, extreme resource scarcities to discrimination and violence. This makes the health care industry a tough work environment for health care personnel to operate in. South Africa has experienced the loss of thousands of nurses over the past decade, either emigrating or leaving the nursing profession altogether (Tshitangano, 2013). Consequently, this trend drew the attention to the well-being of nurses in South Africa. The primary objective of this study was to investigate the level of work engagement among private sector nurses in the Western Cape, together with their levels of job demands, job resources, personal resources, performance and job crafting. This was done using the Job Demands-Resources model (JD-R) of work engagement. The comprehensive JD-R model was tested and the validity of the proposed relationships between the constructs was examined. Moreover, additional paths in the model were proposed and tested. Managerial implications along with practical interventions were derived from the results with the aim to increase nurse well-being and retention. An ex post facto correlational design was used to test the formulated hypotheses in this research study. Quantitative data were collected from 311 nurses employed by a private hospital group by means of non-probability convenience sampling. A self-administered paper copy survey was distributed to hospitals given that they agreed to participate in the research. The survey was voluntary, anonymous and confidential. The survey consisted of five sections and included questions from five existing questionnaires, namely, the Utrecht Work Engagement Scale (UWES-17) (Schaufeli & Bakker, 2003), the Job Demands-Resources Scale (Rothman, Mostert & Strydom, 2006), the Work Design Questionnaire (Morgeson & Humhprey, 2006), the Psychological Capital Self-Rated Version (PsyCap-24) (Luthans, Avolio, Avey & Norman, 2006), and the Job Crafting Scale (Tims, Bakker & Derks, 2012). In order to test the statistical significance of the hypotheses, the data were subjected to Structural Equation modelling and regression analyses. The results indicated that the nurses experienced a high level of work engagement, and elucidated the fact that job resources, job demands, and job crafting aspects of their jobs are in need of industrial psychologist or managerial interventions.
AFRIKAANSE OPSOMMING: Die Suid-Afrikaanse gesondheidsisteem word geteister deur verskeie uitdagings wat onder andere inkomste ongelykhede, ekstreme hulpbron skaarshede, diskriminasie en geweld insluit. Dit maak die gesondheidsindustrie ʼn moeilike werksomgewing vir gesondheidspersoneel om in te werk. Suid-Afrika het duisende verpleegsters oor die laaste dekade verloor as gevolg van emigrasie, terwyl ander die professie in geheel verlaat het (Tshitangano, 2013). Gevolglik het hierdie tendens die aandag getrek na die welstand van verpleegsters in Suid-Afrika. Die primêre doel van hierdie studie was om die vlak van werksbetrokkenheid onder ʼn steekproef van privaatsektor verpleegsters in die Wes-Kaap te ondersoek, tesame met hulle vlakke van werkseise, werkshulpbronne, persoonlike hulpbronne, werksprestasie en posverryking. Die Job Demands-Resources model (JD-R) of work engagement is vir hierdie doel ingespan. Die omvattende model tesame met die geldigheid van die voorgestelde verhoudings tussen die konstrukte is getoets. Addisionele verhoudings is ook voorgestel en getoets. Bestuursimplikasies en praktiese intervensies is van die resultate afgelei en word aan bestuurders voorgelê as moontlike oplossings om verpleegsters se welstand en retensie te verhoog. ʼn Ex post facto korrelasie-ontwerp is gebruik om die geformuleerde hipoteses in hierdie studie te toets. Kwantitatiewe data is van 311 verpleegsters ingesamel wat deur ʼn private hospitaalgroep in diens geneem word. Nie-waarskynlikheid gerieflikheidsteekproeftrekking is gebruik om die steekproef te bepaal. ʼn Self-geadministreerde vraelys is ontwikkel en as harde kopie uitgestuur na dié hospitale wat ingestem het om aan die navorsing deel te neem. Die vraelys is vrywillig, anoniem en konfidensieel ingevul en het uit vyf seksies bestaan. Die vyf seksies se vrae is opgemaak uit verskeie bestaande vraelyste, naamlik, die Utrecht Work Engagement Scale (UWES-17) (Schaufeli & Bakker, 2003), die Job Demands-Resources Scale (Rothman, Mostert & Strydom, 2006), die Work Design Questionnaire (Morgeson & Humhprey, 2006), die Psychological Capital Self-Rated Version (PsyCap-24) (Luthans, Avolio, Avey & Norman, 2006), en die Job Crafting Scale (Tims, Bakker & Derks, 2012). Ten einde die statistiese beduidendheid van die hipoteses te toets, is die data deur strukturele vergelykingsmodellering en regressie-ontledings ontleed. Die resultate dui daarop dat die verpleegsters 'n hoë vlak van werksbetrokkenheid ervaar, en dat werkshulpbronne, werkseise en posverrykende aspekte van hulle werk bestuurs- of bedryfsielkundige intervensies verlang.

The purpose of this study was to present and understand the experiences of HIV-positive lay counsellors working in Voluntary Counselling and Testing (VCT) settings. Specifically exploring and understanding the utilisation of personal experiences within counselling encounters, the practice of peer counselling within VCT, and the challenges experienced by HIV-positive lay counsellors within VCT settings. This study, employing a qualitative interpretative phenomenological methodology required a small sample of practicing HIV-positive lay counsellors, who were selected and interviewed on their experiences utilising semi-structured interviewing. Data was analysed for meaning units, which were interpreted inductively and hermeneutically, and categorised into super-ordinate themes. Three superordinate themes within the participants’ experiences of providing VCT services were determined, namely: ‘diagnosis and disclosure experiences’, ‘peer counselling’, and ‘challenges’. This research found that the experiences of providing peer counselling depended upon identification with their client’s negative appraisal of their diagnosis experiences. Whether through empathic connections generated through the shared experience of discovering a seropositive status, or through countertransferential reactions induced through their client’s yearning for care and support. This required the counsellor to selfdisclose within counselling encounters in order to provide personal experiences of living with HIV/AIDS. Successful implementation of peer counselling provided recently diagnosed individuals with knowledge surrounding HIV/AIDS, coping skills to manage the daily physiological and psychological challenges, facilitation and adherence to treatment, social assistance, ongoing relationships, inspiring hope, and the creation of positive appraisals. However the informal utilisation of task-shifting within lay healthcare cadres, and the lack of governmental recognition for the emotional labour provided within VCT indicated that HIVpositive lay counsellors require ongoing training, support and remuneration to limit potential occupational stress, resignation, and burnout.

Parish nursing, a specialty nursing practice which includes the spiritual component of integration of faith and health, has been growing rapidly over the last decade. Standards of Parish Nursing Practice developed in 1998 are consistent with the nursing process and include the spiritual dimension.
