A prospective, longitudinal and observational study, using a non-clinical population of mother-child dyads was conducted to evaluate the contribution of family-environmental factors in predicting child food avoidance and feeding problems across early childhood. The contribution of maternal feeding practices, mealtime structure and interactional behaviour during mealtimes, were explored in predicting child food avoidance between 2 and 5 years, whilst also evaluating the role of maternal psychopathology and child temperament. This thesis also assessed the validity of maternal reports of child eating behaviour and feeding practices by obtaining independent observations of these constructs, and explored the longitudinal stability and continuity of both independent observations and maternal reports of child eating behaviour and maternal feeding practices. Concurrently and prospectively, observations of mothers eating with their child, displaying high sensitivity, low control, and more positive emotion and verbalisation during mealtimes predicted less avoidant child eating behaviour. Reports of mothers providing a healthy food-related home environment, encouraging balanced food intake, and involving their child in food planning, in addition to a less emotional child temperament, were also significant longitudinal predictors of less avoidant child eating behaviour. Maternal descriptions of their child s eating behaviour were validated by independent observations; however maternal descriptions of their own feeding practices were not. Child eating behaviour and maternal feeding practices were predominantly stable and continuous across early childhood, with the exception of child difficulty to feed and maternal pressure to eat which decreased between the ages of 3 and 4. This thesis demonstrates many interesting and novel findings but primarily through the utilisation of observational and longitudinal data it demonstrates the important causal contribution of family-environmental factors in the development of food avoidant eating behaviours during early childhood.

Because the way mothers play with their children may have significant impacts on children's social, cognitive, and linguistic development, researchers have become interested in potential predictors of maternal play. In the present study, 40 mother–infant dyads were followed from child age 5–20 months. Five-month habituation rate and 13 and 20 month temperamental difficulty were found to be predictive of maternal play quality at 20 months. The most parsimonious theoretical model was one in which habituation was mediated by temperamental difficulty in predicting mother play. Consistent with prior speculation in the literature, these data support the possibility that mothers adjust some aspects of their play behaviors to fit their children's cognitive and temperamental capabilities.

Abstract Personality disorders (PDs) are relatively common mental disorders associating with other psychiatric disorders and disability. The aim of the study was to determine the occurrence of PDs in a general population subsample and psychiatric hospital patients, the associations of PDs with childhood family structure, the co-occurrence of PD with common psychiatric disorders, and the associations between PDs and temperament. The study is part of the Northern Finland 1966 Birth Cohort Project (NFBC 1966), consisting of cohort members living in Oulu (N = 1,609) on 1st January 1997 (the Oulu Study). The study consisted of a two-stage psychiatric field survey with questionnaires and a structured clinical interview and analysis of the patient records in public outpatient care. Information concerning psychiatric illness of all cohort members (N = 12,058) was gathered from the Finnish Hospital Discharge register (FHDR). The best-estimate procedure was used for the assessment of psychiatric morbidity including PDs. Childhood family structure and other sociodemographic variables were drawn from questionnaires of the field study conducted during earlier follow-up studies. In this study PDs were classified into three clusters: Cluster A (paranoid, schizoid and schizotypal PD), Cluster B (antisocial, borderline, histrionic, and narcissistic PD), and Cluster C (avoidant, dependent, obsessive-compulsive, and passive-aggressive PD). The most common PDs in the Oulu Study sample were Cluster C PDs, whereas Cluster B PDs were most common in the hospital-treated sample. PDs were highly associated with mood, anxiety and substance use disorders. Single-parent family type in childhood was associated with PDs, especially Cluster B PDs in adulthood. PD clusters were associated with different profiles of temperament, but the temperament dimensions could not distinguish different PDs very well. These results indicated that it is important to recognize PDs and their comorbid psychiatric disorders. This will have implications in both general outpatient care and psychiatry. These results indicate the importance of recognition of childhood risk factors for PDs for the prevention of severe PDs. The results suggest a need for more studies about the aetiology and development of PDs<br>Tiivistelmä Persoonallisuushäiriöt ovat yleisiä mielenterveyden ongelmia, joihin liittyy usein psykiatrista oheissairastavuutta ja toimintakyvyn laskua. Tämän tutkimuksen tarkoituksena oli arvioida persoonallisuushäiriöiden yleisyyttä nuorilla aikuisilla. tehtävänä oli arvoida yhteyksiä lapsuuden perherakenteeseen ja yleisimpiin psykiatrisiin häiriöihin sekä arvioida persoonallisuushäiriöiden yhteyksiä temperamenttitekijöihin. Tutkimus on osa Pohjois-Suomen vuoden 1966 syntymäkohortin psykiatrista osaprojektia, Oulu Studyä. Tutkimusaineiston muodostivat Oulu Studyn otokseen kuuluvat kaikki 1. tammikuuta 1997 Oulussa asuneet kohortin jäsenet (N = 1 609) sekä sairaalahoidossa olleiden persoonallisuushäiriö- diagnoosin saaneiden osalta koko alkuperäisen syntymäkohortin (N = 12 058) jäsenet. Tutkimus koostui kaksivaiheisesta psykiatrisesta kenttätutkimuksesta, jossa tietoja tutkittavilta kerättiin sekä kyselylomakkeiden ja haastattelututkimuksen avulla. Lisäksi tutkittavilta kerättiin tiedot heidän elinaikanaan toteutuneesta julkisten psykiatristen sairaala- ja avohoitopalvelujen käytöstä sairauskertomustietojen perusteella. Niin kutsutun best-estimated -menetelmän avulla arvioitiin tutkittavien psykiatrista sairastavuutta mukaan lukien persoonallisuushäiriöt. Tutkittavien lapsuuden perherakennetta ja sosiodemografisia tekijöitä arvioitiin aiempien seurantatutkimusten tietojen avulla. Tutkimuksessa persoonallisuushäiriöt luokiteltiin DSM-III-R-diagnoosiluokituksen mukaisesti kolmeen eri pääryhmään ja niiden mukaisiin alaryhmiin: Ryhmä A (epävakaa, eristäytyvä ja psykoosipiirteinen persoonallisuus), ryhmä B (epäsosiaalinen, epävakaa, huomionhakuinen ja narsistinen persoonallisuus) ja ryhmä C (estynyt, riippuvainen, pakko-oireinen ja passiivis-aggressiivinen persoonallisuus). Oulu Studyn väestöotoksessa yleisimpiä näistä olivat ns. C-ryhmän persoonallisuushäiriöt, kun taas sairaalahoidetuilla henkilöillä B-ryhmän persoonallisuushäiriöt olivat yleisimpiä. Persoonallisuushäiriöiden todettiin liittyvän yleisesti masennus- ja ahdistuneisuushäiriöihin sekä päihteiden käyttöön. Vanhemman yksinhuoltajuuden todettiin liittyvän persoonallisuushäiriöihin, etenkin B-ryhmän persoonallisuushäiriöihin. Persoonallisuushäiriöryhmät erosivat toisistaan temperamenttiprofiilien perusteella. Eri persoonallisuushäiriöistä kärsivillä tutkittavilla ei todettu tyypillisiä temperamenttiprofiileja. Johtopäätöksenä voidaan todeta, että persoonallisuushäiriöiden ja niihin yleisesti liittyvän psykiatrisen oheissairastavuuden tunnistaminen on tärkeää. Havainnot korostavat perusterveydenhuollon ja erikoissairaanhoidon yhteistyön merkitystä persoonallisuushäiriöistä ja psykiatrisista häiriöistä kärsivien henkilöiden tutkimuksessa ja hoidossa. Persoonallisuushäiriöille altistavien lapsuuden tekijöiden tunnistaminen on tärkeää vaikeiden persoonallisuushäiriöiden ehkäisemiseksi. Persoonallisuushäiriöiden etiologian ja kehittymisen selvittämiseksi tarvitaan uusia tutkimuksia

An experiment was conducted investigating the utility of teamwork exercises and problem structure for promoting technological problem solving in a student team context. The teamwork exercises were designed for participants to experience a high level of psychomotor coordination and cooperation with their teammates. The problem structure treatment was designed based on small group research findings on brainstorming, information processing, and problem formulation. First-year college engineering students (N = 294) were randomly assigned to three levels of team size (2, 3, or 4 members) and two treatment conditions: teamwork exercises and problem structure (N = 99 teams). In addition, the study included three non-manipulated, independent variables: team gender, team temperament, and team teamwork orientation. Teams were measured on technological problem solving through two conceptually related technological tasks or engineering design activities: a computer bridge task and a truss model task. The computer bridge score and the number of computer bridge design iterations, both within subjects factors (time), were recorded in pairs over four 30-minute intervals. For the last two intervals with the computer bridge, teams started construction of the truss model task, which created low and high task load conditions for the computer bridge: another within subjects factor. A repeated measures ANOVA was used to analyze time (computer bridge) by factor interactions. No significant time by teamwork exercises or time by problem structure interactions on computer bridge scores were found [F(2.31, 198.46) = 0.10, p = .928; F(2.31, 198.46) = 0.03, p = .984]. There was a significant interaction between the factors of time and team size [F(4.62, 198.46) = 2.75, p = .023]. An ANOVA was conducted with the between subject factors on the truss model task. A significant main effect was found for teamwork exercises [F(1, 86) = 2.84, p = .048, one-tailed], but not for problem structure or team size. Post hoc analyses were conducted for team size on computer bridge and iteration scores over time, as well as teamwork exercises effects for each team size. Findings and their implications were reported, along with suggestions for future research on technological problem solving in a team context.<br>Ph. D.

Temperament is thought to be the foundation for normative personality and subsequent behaviors later in life. To assess the relationship of early temperament with variation in structural brain development, this study examined rhesus macaque mother-infant behavior, and then three years later, used MRI to assess neurostructural differences. Individual differences in mother-infant interactions and emotionality were then linked to brain differences. Extensive behavioral data obtained over the first year of life under both resting and stressful conditions was used to assess the quality of mother-infant interactions and emotionality. The MRI focused on brain volume in areas thought to be related to emotional regulation and such as the cingulate gyrus and corpus callosum structures. These structures are often mentioned as areas that modulate emotions, temperament and general social behavior. The methods involved in this research include behavior coded from group-housed infant rhesus macaques (Macaca mulatta). The subjects were 15 mother-reared subjects, each housed in a social group of 12-20 subjects, living in social settings with their mothers, other adult females, two adult males, and other same-aged subjects; conditions that approximate the social composition of the natural setting. Behaviors related to temperament and mother-infant interactions were assessed using an objective behavioral scoring system. Behavior was coded under three conditions, and each behavioral coding session was 5-minute long. Homecage: Two behavioral coding sessions were recorded weekly for each subject as it interacted naturally with its mother and peers over the first six-months of life. Preseparation (month 6): Two weeks before four, sequential, 4-day social separations, behavioral data were collected once each day. Reunion with mother: Following each of the social separations, data were collected twice immediately following return to mother and again on the morning before the separation. Subjects underwent MRIs 1-2 years later when they were 2-3 years of age. The result of this research was that during pre-separation interactions, anterior cingulate size to brain ratio showed a positive correlation with mutual ventral contact (being cradled and held closely), a measure of the use of mother as a secure base to calm anxiety and fear.

Young's schema theory offers a theoretical approach that relates negative childhood experiences, temperament, and early maladaptive schema, to the experience of negative affect and/or depression in adulthood. However, despite the widespread use of schema therapy in clinical practice, little research has explored the pathways theorized by Young. This study explored the pathways posited by Young and colleagues looking at the direct and indirect relationships among negative childhood experience, temperament, early maladaptive schema, and the experience of negative affect in adulthood. Self-report data were collected from 365 undergraduate students. Results demonstrated consistent and robust direct relationships between temperament and negative affect, as well as indirect relationships between temperament and/or NCE, schema, and the outcome of negative affect. Results, though mixed, reveal strengths of the schema therapy model and provide suggestions for future research.

Interactional and contextual models have been conceptually proposed in understanding parental influences on children. Yet, empirical model testing has been limited. The purpose of this exploratory study was to investigate the direct and indirect effects of parenting style on child social competence using structural equation modeling in a sample of 544 Chinese families with 6-9 years old children, mainly singleton, residing in Nanjing, China. Five latent models were tested: (a) the direct model between parenting style and child social competence, (b) child temperament as a moderator, (c) parent-child relationship as a mediator, (d) the interaction model between parenting style and family functioning, and (e) bidirectional models of parenting style concurrently with parent-child relationship, and family functioning predicting child social competence. Findings showed: (a) The direct relationship between parenting style and child social competence was significant in both parents with authoritative parenting style on the positive direction, whereas authoritarian and permissive parenting styles on the negative direction; (b) child temperament did not moderate parenting style on child social competence; (c) father-child relationship mediated paternal parenting style on child social competence, whereas maternal parenting style did not; (d) family functioning neither moderated nor mediated the relationship between parenting style and child social competence for both parents; and (e) The four-factor prediction models on child social competence turned out to be unidirectional. For the mothers, the best model was from family functioning to mother-child relationship, to maternal parenting style, and finally to child social competence. Maternal parenting style was the significant proximal factor. For the fathers, it was from family functioning to paternal parenting style, to father-child relationship, and then to child social competence. Father-child relationship had the direct impact, whereas the influence of paternal parenting style was distal through father-child relationship. Findings from this study suggest that the Chinese parents should use more authoritative and less authoritarian and permissive parenting, and develop good parent-child relationships in the daily interactions with their children. Future studies need to use larger and better data to validate these models, or to extend the findings with other important child variables to explore the child's active agency.

Annotation: The thesis deals with a problem of personality in the context of the top athletes' and top managers' activities. Comparison of the demands of these activities on the human and comparison of the personality profile results in a finding that there is a certain consensus in the personality profiles of top athletes and top managers and also to the conclusion that there is a noticeable difference between them in the emotional area. Title: Comparison of personality traits of top athletes and top managers. Objectives: Find a set of personality traits characteristic for particular groups of athletes and for a group of top managers and to determine which of the psychological characteristics of these groups are similar, respectively. Confirm the hypothesis: "It is possible to suppose that the personality traits of athletes match the demands of the sport sector, as well as the personality traits of the top managers correspond with the demands of their professional activities, and that there is a consensus in the personality characteristics of athletes and top managers, which corresponds to a consensus on demands of these two activities ". Methods: Cattell's 16 P. F. Questionnaire, correlation analysis according to Spearman, calculation of the statistical significance of the difference by the...

The goal of this thesis was to study early social games in natural interaction between mother and child of 4 month age. Infant's affectivity and gaze orientation as a sign of participation was coded. We also observed how can mother and infant influence the social game routine. We examined mother's warm sensitivity and infant's temperament as a variables potentiallz influenced the social game interaction. Fifty five dyads participated in the present study when infants were four months old. Social games were analyzed in natural mother-infant interaction and identified on the given criterions. To assess maternal warm sensivity Materna Affect Attunement was used. Mother's evaluated infant's temperament on fourteen scales of IBQ-R. The results indicate that social games are an inherent part of mother-infant interactions in infant's 4 months of age, and their occurance is influenced by temperament. Keywords: play, game, social game routine, structure, social interaction, infant's positive affect infant age, sensitivity, temperament

碩士<br>國立嘉義大學<br>家庭教育研究所<br>94<br>Relationships between Temperament, Parent-Child Interaction, and Frustration Tolerance：A Structural Equation Modeling Approach Shu-Yu Chang Graduate Institute of Family Education National Chiayi University Abstract The main purpose of this study was to investigate the relationships among the temperament, parent-child interaction and frustration tolerance of the high-grade students in the primary school. A questionnaire was adopted to survey on the fifth and sixth grade students in Chiayi county. The instruments used in the study include Basic Background Questionnaire, Temperament Scale, Parent-child Interaction Scale and Frustration Tolerance Scale. The statistical methods used to analyze the data were, descriptive statistic, t-test, one-way ANOVA, and structural equation modeling (SEM). The findings of the study were concluded as follows：Presently, the temperament has vibrations with above-average level, and deflects to positive. The parent-child interaction and frustration tolerance was at middle and high level. There was no significant difference in temperament. The family structure significantly affected parent-child interaction and frustration tolerance. There was significant difference in frustration tolerance between the fifth-graders and the sixth-graders .The elder was greater than the middle child in parent-child interaction and frustration tolerance. An only child was greater than the middle child and youngest children of the family in frustration tolerance. The temperament had a direct and positive relationship to the parent-child interaction and frustration tolerance. The parent-child interaction had a direct and positive relationship to the frustration tolerance. The impact of the temperament on the frustration tolerance was mediated by the intermediate factor –the parent-child interaction. Finally according to the research findings, this study provides some suggestions for school education, the relative workers of family education and the future studies. Key words：temperament, parent-child interaction, frustration tolerance, structural equation modeling

Although research is unequivocal concerning the important role of parenting in the prediction of a range of youth psychosocial outcomes, few empirical studies have examined potential contributions of parental individual differences factors to variability in parenting behaviors. Among the few studies that have, individual differences in affective dimensions of temperament (i.e., Negative Temperament [NT] and Positive Temperament [PT]) and executive functioning (EF) have individually emerged as potential key processes underlying parenting behaviors; however, they have yet to be examined jointly. Thus, using a latent variable approach, within a racially and ethnically diverse community sample of 166 parents, the current study examined the joint and interactive contribution of temperament and EF in the explanation of parenting. Further, despite conceptual overlap, parenting research has historically employed two distinct conceptual approaches: parenting practices and styles. The current study thus fitted a single integrative three-factor model (i.e., positive parenting, negative parenting, and corporal punishment) of parenting behaviors that included both styles and practices. Results suggested that parenting behaviors can be conceptualized within a single, three-factor model, allowing for the incorporation of historically distinct conceptions of parenting. Further, results revealed that affective dimensions of temperament and EF were uniquely but differentially associated with all parenting domains and EF moderated the associations between both NT and PT and positive parenting. All told, the current study provides support for an integrative model of parenting behaviors and parental temperament and EF, and their interaction, as potential critical processes associated with individual variability across parenting behaviors.

Bronfenbrenners Process-Person-Context-Time model was used to examine the relationships among the process of negative parenting, the person characteristics of child temperament and early aggressive behaviour and the contexts of family income (in)adequacy and maternal depression from infancy to school entry and their effects on the outcome of aggressive behaviour in boys at school entry. The sample included 361 boys in two-parent families who participated in the Canadian National Longitudinal Survey of Children and Youth (NLSCY). Structural equation modeling was used with a repeated measures longitudinal design. The model explained 43% of the variance in boys aggressive behaviour at school age. The results indicated that, by preschool age, boys and mothers behaviours are well established, and that process, person, and context variables all influence the persistence of boys aggressive behaviour. The strength of the effects of these variables increased with their proximity to the developing child and decreased over time. By school age, concurrent effects were not significant. The addition of the contextual variables resulted in ill-fitting models. Modification indices suggested the ill fit was localized in modeling the persistence of maternal depression, and not in the relationship between maternal depression and the other variables in the model. Modification indices also suggested there may be reciprocal effects between boys aggressive behaviour and both negative parenting and maternal depression, but this was not tested. Future research using a cross-lagged panel design could clarify these relationships. This study contributes to a growing body of research on the development of aggressive behaviour in children and underscores the importance of examining the contribution of the multiple levels of process, person, context, and time to the development of aggressive behaviour. Findings of this study provide evidence that the effects of proximal processes and proximal contexts on the development of boys aggressive behaviour are strongest in infancy and toddlerhood, and their consequences extend through to school entry. Initiating prevention and intervention efforts in early childhood that provide parents-to-be and parents of young children with practical direction in ways to engage in positive and responsive interactions with their children would do more to reduce the development of aggressive behaviour in children than would later interventions aimed at changing entrenched behaviours in both parents and children.
