Abstract:
Malgré quelques limites, le coefficient alpha de Cronbach reste l'indicateur de fidélité d'échelle le plus utilisé. Le but de cet article est de passer en revue l'ampleur des coefficients alpha obtenus dans les recherches comportementales empiriques, de confronter ces valeurs obtenues aux règles et aux recommandations préconisées par des chercheurs tels que Nunnally (1967, 1978), et d'apporter des éclairages sur les caractéristiques de plan de recherche susceptibles d'influencer la taille du coefficient alpha. Les moyennes des coefficients alpha rapportés dans la littérature vont de 0,70 pour les valeurs et les croyances, à 0,82 pour la satisfaction au travail. Hormis quelques exceptions, il n'existe aucune relation substantielle entre l'ampleur du coefficient alpha et les caractéristiques des plans de recherche examinés.

Abstract:
This study aims to describe the effects of variability through data simulation to determine which aspect of variability that maximizes coefficient of Cronbach Alpha reliability. Cronbach Alpha is widely used for estimation of reliability, in recent still. This study served a conceptual and practical simulation for estimating the profound aspect of Cronbach Alpha coefficient relating to the variability of the data. This study carried out with data simulated using the rand between method by Microsoft Excel then simulate different categorical data responses to different range of items by manipulating sample size, range, number of items, variance and standard deviation. The results show that number of variance and standard deviation of data had the most profound aspect of Cronbach Alpha's reliability other than range. The increasing number on some aspect shows that standard deviation and variance has the stability to shows the positive correlation with the coefficient of Cronbach Alpha reliability other than range.

<p>This research aims to compare the internal consistency of reliability coefficient on classical test theory. Estimation accuracy of internal consistency reliability coefficient used several methods of the coefficient reliability formulation. The methods are Split-Half Method, Cronbach Alpha formula, and Kuder Richardson formula. Determination of the test reliability coefficients used also some formula and then their results were compared with the results of their estimation accuracy. This research is a quantitative descriptive. Data were analyzed based on responses of national chemistry examination in Jambi province on academic year 2014/2015. The data of students answer sheets were taken using proportional stratified random sampling technique. There are 200 students’ responses from 162 schools (132 public schools and 30 private schools) in Jambi province. The form of data were dichotomy data and analyzed using Split-Half Method. Their reliabilities were analyzed using Cronbach Alpha formula and Kuder Richardson formula. Reliability criteria used consist of five conditions, they are 0.5; 0.6; 0.7; 0.8 and 0.9. The results of this research indicated that (a) the coefficient of reliability in classical test theory developed by measurement experts (using Split-Half Method, Cronbach Alpha formula and Kuder Richardson formula) have varying estimates of accuracy; (b) average reliability coefficients have the precision estimation about of 0.78 up to 0.8; (c) the reliability coefficient using Spearman Brown formula was 0.78, with Rulon formula was 0.78, Flanagan formula was 0.77, Cronbach Alpha formula was 0.838, the KR20 formula was 0.838, and KR21 formula was 0.82<em>1.</em></p>

Abstract:
Object This study was undertaken to assess the reliability of observations of postoperative photographs in assigning House-Brackmann scores as outcome measures for patients following resection of vestibular schwannomas. Methods Forty pictures of differing facial expressions typically elicited from patients for assigning House-Brackmann scores were individually evaluated by neurosurgery residents and faculty members at the University of Alabama at Birmingham; a score was assigned to each picture by the individual raters. The interrater reliability was measured using the Spearman correlation coefficient, Kendall coefficient of concordance, and kappa statistic; internal consistency was calculated using the Cronbach alpha reliability estimate. Results The Spearman correlation coefficients showed strong positive association among raters, with a range of values of 0.66 to 0.90. Internal consistency measured by the Cronbach alpha coefficient was excellent (α = 0.97). The Kendall coefficient of concordance for the ordinal grades suggested a substantial degree of agreement among the raters (w = 0.76, p < 0.001). Conclusions Static postoperative photographs are a reliable outcome measure for determining facial nerve function after vestibular schwannoma resection and may serve as a surrogate for the dynamic patient interview.

Abstract:
Studies indicate that many students engage in procrastination, thus in this study the aim was to examine the structural relationship of early maladaptive schemas and academic procrastination with the mediating role of the perfectionism in students. The participants included 281 high school students (143 male, 138 female) that were chose by multistage cluster sampling method. Solomon and Rothblum’s academic procrastination scale with the Cronbach alpha coefficient 0.81 and Young early maladaptive schema questionnaire with the Cronbach alpha coefficient 0.93, and Positive and Negative Perfectionism questionnaire with the Cronbach alpha coefficient 0.86 were administered. Structural Equation Modeling (SEM) and Sobel tests were conducted to explore direct and indirect pathways of study’s model respectively. Results showed that early maladaptive schemas and academic procrastination are antecedents and consequences of perfectionism in students respectively. The results indicated that perfectionism has a significant mediating role on the relationship between early maladaptive schemas and academic procrastination. The findings of this study could help school counselors, education psychologist, and teachers to reduce student’s procrastination and academic problems.

This cross-sectional study included 789 adolescent mothers who delivered at a maternity hospital in Lima, Peru. The Spanish version of the 10-item CD-RISC was used to measure resilience. Internal consistency and construct validity were assessed by evaluating individual item characteristics as well as the association of CD-RISC score with symptoms of depression, anxiety and sleep disturbance. Exploratory factor analysis (EFA) was performed to test the factorial structure of the CD-RISC. The CD-RISC was found to have good internal consistency (Cronbach’s alpha = 0.85). CD-RISC scores were positively associated with school attendance, financial hardship, and history of childhood abuse; scores were negatively associated with household dysfunction, depression, anxiety and poor sleep quality. The results of the EFA showed that the CD-RISC contained a two-factor solution, which accounted for 46% of the variance. Overall, these findings suggest that the Spanish-language version of the CD-RISC-10 is an adequate measure of resilience in this population. Further research is needed to incorporate culturally-specific constructs into resilience measures.<br>National Institutes of Health<br>Revisión por pares

Abstract:
The study of outliers and their impact on statistical results is important because outliers are prevalent in real data. Previous research has focused on outlier identification and treatment with no studies having investigated whether outliers have impact on the estimated Cronbach's coefficient alpha. This is an important gap in the research literature because coefficient alpha is the most widely used measurement statistic in all of the social sciences. The purpose of this study is to investigate whether outliers impact the value of coefficient alpha at different amounts of outlier contamination, the distance of the center of the contamination population distribution from the uncontaminated parent population, and standard deviation of the contamination population for varying values of population reliability and sample sizes. The overall results indicate that the estimates of coefficient alpha are not affected by symmetric outlier contamination (i.e., when the means of the contamination and parent distributions are equal), whereas asymmetric outlier contamination artificially inflates the estimates of coefficient alpha. In particular, this upward bias of coefficient alpha estimates and inflation in statistical efficiency (i.e., stability) are greater with increasing asymmetry and proportion of outlier contamination. These effects of outliers on the bias and efficiency of coefficient alpha estimates are reduced for increasing population reliability.<br>Education, Faculty of<br>Educational and Counselling Psychology, and Special Education (ECPS), Department of<br>Graduate

Abstract:
Indiana University-Purdue University Indianapolis (IUPUI)<br>GREGORY RESEARCH BELIEFS SCALE: FACTOR STRUCTURE AND PSYCHOMETRIC PROPERTIES The study at hand involves developing the Gregory Research Beliefs Scale (GRBS) to reliably and validly measure social work students’ beliefs about the function of research in social work practice. Research has considerable actual and potential benefits for practice. Social work students’ beliefs about this construct are vital. A description of the advantages of using research to inform practice is given. Additionally, the Council on Social Work Education and National Association of Social Workers’ policies that mandate the merger of research and practice are also provided to further justify the need for adequate psychometric evaluation of the construct. Details of the literature search strategy are described and critical evaluations of the empirical articles are conducted. Based on critical evaluations of instruments which have previously measured the same construct, a number of psychometric shortcomings are outlined to validate the need for further scale development of the construct. The present study’s objectives were to develop a scale which has an empirically and theoretically supported factor structure, acceptable coefficient alpha levels, empirically supported discriminant (divergent) validity, concurrent criterion validity, and known–groups criterion validity. Steps for developing the GRBS’s items, response format, sample, research design, and statistical tests are specified and conducted to determine the factor structure and psychometric properties. Finally, the strengths, limitations, and areas for future research are discussed.

Abstract:
The SLAI measures the seven concepts found in Patterson’s (2003) theory of servant leadership. According to Patterson, the servant leader (a) leads and serves with love (Winston, 2002), (b) acts with humility (Sandage &amp; Wiens, 2001), (c) is altruistic (Kaplan, 2000), (d) is visionary for the followers (Tangney, 2000), (e) is trusting (Hauser and House, 2000), (f) is serving (Wis, 2002), and (g) empowers followers (Covey, 2002). These are the seven constructs that comprise the servant leadership in Patterson’s model. Servant leadership as a theory emerged from Robert Greenleaf’s (1977) work. Recent investigations have expanded servant leadership to include identification and assessment servant leadership factors (Dennis &amp; Bocarnea,2005; Dennis &amp; Winston, 2003; Laub, 1999; Page &amp; Wong, 2000; Patterson, 2003; Russell, 2000; Russell &amp; Stone, 2002). The 42 items of the Servant Leadership Assessment Instrument (SLAI) cover a variety of attitudes and behaviors reflective of the aforementioned research. Reliability Research has indicated that the SLAI is internally consistent and reliable. Alpha reliability coefficients ranging from .89 to .92 have been reported (Dennis, 2004) for factors of love, empowerment, vision, and humility. Trust factor, however, has loaded with two items on two second data collections (Dennis, 2004) and one sample (Irving, 2005). The following alpha coefficients were found, measuring servant leadership at the individual leader level: (a) .92 for the SLAI love scale; (b) .92 for the SLAI empowerment scale; (c) .8637 for the SLAI vision scale; and (d) .92 for the SLAI humility scale. A Cronbach alpha coefficient could not be calculated for the SLAI trust scale because it only has two items in the scale (Irving, 2005).

Abstract:
Prior knowledge is a complex variable that greatly determines the outcome of learning of science students. Prior knowledge inherent qualities facilitate or interfere in the process of learning; however it hasn´t always been possible to determine the extent and explicitness of these effects on learning. A test to measure these effects was developed with the intention to discern the specific influence of the inherent qualities of prior knowledge of incompleteness, correctness, misconceptions and the absence of declarative knowledge. This multiple choice test includes topics such as vectors, trigonometry, unit systems and prefix definitions, contents considered to be essential to learn Coulomb´s law for electricity and magnetism course in engineering major. The ultimate goal of this project was to design a test with content validity and determine the reliability of this test using Cronbach´s alpha coefficient with a minimum value of 0.7. Finally we present suggestions that can guide future research and the applicability of this test.

Abstract:
This chapter empirically investigated the mediating effect of organizational culture, size and structure on the relationship between innovations and resilience in selected Nigerian universities. The descriptive research design was adopted. The respondents comprised Heads of Departments, Deans of Faculties, Directors, Registrars and Deputy Registrars, and Vice Chancellors and Deputy Vice Chancellors. The analyses of the data involved the use of multiple statistical procedures: Percentages, Mean, Chi-square (hypotheses 1-6) and One-way Analysis of Variance (ANOVA). ANOVA was used to test hypotheses 7-12, using the statistical package for social sciences (SPSS) version 21. The research instrument was quantitatively analyzed and an overall Cronbach alpha coefficient of .845 was realized. In this study, we gathered that significant relationship exists between product innovation and situation awareness, keystone vulnerabilities and adaptive capacity. Process innovation impact on situation awareness, keystone vulnerabilities and adaptive capacity. In addition, relationships were found between administrative innovation and situation awareness, keystone vulnerabilities and adaptive capacity. Correspondingly, we found that organizational culture, size and structure has a significant moderating relationship between innovation and resilience. Nigeria universities like other developing counties universities need effective innovation programs.

Abstract:
The Nonprofit Ethics Survey serves as the only empirically supported survey instrument specifically designed for nonprofit organizations to assess their ethical culture. Development of the instrument occurred through the use of principal components analysis conducted on a sample of 530 nonprofit affiliates. The results of the analysis yielded six parsimonious scales integral to assessing nonprofit ethics. To evaluate the internal reliability of each scale a measure of Cronbach’s Alpha was also calculated. The alpha coefficients ranged from 0.86 - 0.94, indicating the survey provides a reliable means of measuring the constructs integral to assessing organizational ethics in nonprofit agencies. The creation of a statistically sound instrument designed for use with nonprofit organizations ensures that nonprofit leaders have the needed tools to accurately self-assess.

Abstract:
This chapter investigated possible links between religious motivations, attitudes, and coping in the face of death in Brazil. The participants included 478 people aged between 41 and 100 years, most of them women (77.82%). It employed the religious orientation scale (31 items), religious coping scale (33 items), and scale of attitudes in the face of death (46 items). Data were analyzed by means Pearson product-moment correlation coefficient (Pearson), analysis of variance (ANOVA), exploratory factor analysis and internal consistency analysis (Cronbach's alpha). The overall survey results are presented in two large blocks. The first describes the correlations between the factors of religious coping, religious orientation, and attitudes in the face of death.

Abstract:
INTRODUCTION: Many instruments have been used to identify older adults at risk of falling, including performance-oriented mobility assessment, timed up and go test, Berg balance scale, and dynamic gait index. However, there have been reports of these clinical tests having a ceiling effect on community-dwelling older adults. To address this issue, the functional gait assessment was developed based on the dynamic gait index. Therefore, the functional gait assessment is an instrument that assesses postural stability during tasks that cause changes in gait patterns. OBJECTIVES: To translate and cross-culturally adapt the functional gait assessment to the Brazilian Portuguese language and to assess its psychometric properties in older Brazilians living in the community. METHODS: The process of translation and cross-cultural adaptation followed the recommendations of international guidelines. The pre-final version was administered to a sample of 30 older adults, both male and female, living independently in the community. To examine the psychometric properties (reliability, standard error of measurement, and internal consistency), 70 older adults aged 60 to 87 years were evaluated. RESULTS: The original and the translated versions were considered conceptually equivalent. All functional gait assessment items whose numbers were measured in inches and feet were converted to centimeters and rounded off to comply with the unit of measurement used in Brazil. The functional gait assessment-Brazil showed excellent inter- and intraexaminer reliability (intraclass correlation coefficient &gt; 0.90), low standard error of measurement (range = 1.03 to 1.52), and good internal consistency (Cronbach alpha = 0.858). CONCLUSIONS: The functional gait assessment-Brazil is a semantically, linguistically, and psychometrically appropriate instrument for assessing balance during walking in community-dwelling older adults.

Abstract:
With growing awareness of environmental issues — from global warming to local waste disposal — business and government have come under increasing pressure to reduce the environmental impacts involved in the production and consumption of goods and services. However, organizations consider environmental assessment fairly late in the product development process, which generates additional design constraints and increases the development costs. The integration of environmental requirements through life-cycle stages of a product is a likely approach, leading to a new paradigm of green manufacturing. Empirical studies by various authors have indicated that Small and Medium Enterprises (SMEs) find it difficult to implement environmental issues in product and process design because of lack of time, resources, expertise and/or framework in comparison to large enterprises. This paper presents the results of an empirical study carried out on Indian SMEs to develop product and process characteristics of green manufacturing. Fifteen product and four process characteristics have been developed to be considered during the product and process design to address the environmental issues for the life cycle of the product. These characteristics provide an easy to use self assessment framework to the SMEs to address the various environmental issues during the product and process design. The characteristics identified from the literature have been validated by using SPSS for Windows statistical tool. The reliability and validity of the data has been assessed by the Cronbach alpha and factor analysis respectively. The results provide sure evidence that the developed characteristics are highly reliable having Cronbach alpha values more than 0.9. Factor loading values for all characteristics are above 0.6, which shows the high validity of the data. A high value of Pearson correlation coefficients also reflects the high correlation among the developed characteristics. The study highlights the various environmental issues to be considered by the SMEs during the product design and development phase.

Abstract:
Quality communication between a teacher and a student or students contributes to the process of learning not only a foreign language. Contrarily, fear of communication can significantly harm communication. The present study provides information on the process and results of scale adaptation, which measures foreign language anxiety (Horwitz, Horwitz &amp; Cope, 1986). The process of adaptation to Czech conditions included the verification of content validity, construct validity, and the identification of a factor structure of the instrument. Based on the results of the exploratory factor analysis in the STATISTICA 13.3 program, a reduction from thirty-three to thirteen items was proposed. The internal consistency of the adapted Foreign Language Classroom Anxiety Scale showed a sufficient Cronbach's alpha coefficient of 0.82.

Abstract:
The aim of this study is to identify distribution of occupational diseases and related health complaints among health workers and also to detect employee apprehensions about availability of occupational health and safety issues in the workplace. The application area of this study is a private hospital subservient in Istanbul and accredited by JCI. Within the framework of this study, a survey which contains 8 queries about demographic and personal features, 12 queries about occupational diseases and related complaints and 24 queries about occupational health and safety issues is applied to health staff employed in variable departments and positions in this hospital. The reliability coefficient of this survey is found .816 (Cronbach’s Alpha). In the conclusion of this study; it is detected that the employee’s perception about the occupational health and safety issues in the workplace has a positive aspect. Moreover, arm and leg pains (%65.6), over-fatigue (%64.1), insomnia (%59.7) and presence of venous varicosises (%54.2) were the most determined diseases and complaints, which are considered as work-originated among healthcare workers. In accordance with findings, the privileged improvements about the problems in occupational health and safety issues in this hospital have been presented.

Abstract:
According to data of The Banks Association of Turkey 2017; In Turkey, the banking sector occupies an important place in the country's economy due to the fact that banks employ approximately 200,000 people and foreign capital and partnerships are increasing in this sector. However, there is an intense competition environment in which all instruments in this sector are used. It is necessary to differentiate to achieve a competitive advantage and to achieve sustainable growth. Differentiation can be realized with abstract values rather than tangible values, which are generally not shown in the balance sheet. Corporate reputation holds a strategic place in relations with stakeholders and is placed in an important position in the eyes of stakeholders. In the study, it is aimed to make a structure analysis of the Reputation Coefficient Scale analysis which can be used to measure the corporate reputation. The data obtained from 185 people working in the banking sector in Batman province and analyzed with SPSS 23.00 and AMOS 24.00 programs. As a result of the analysis, Cronbach's alpha value was 0.924 and it was found to be highly reliable. According to the confirmatory factor analysis performed with the Maximum Likehood method, the results of the fit indexes of the model were well and found as X2/df=1,788, RMSEA = 0,065, GFI = 0,903, CFI = 0,945, TLI = 0,926 and IFI = 0,946. ’Reputation Coefficient Scale’ used in the banking sector in Batman province has been determined as reliable and valid in terms of structure.

Abstract:
This paper presents the preliminary evidence for validating the Self-authorship Section of the Career Decision Making Survey (SA-CDMS; Creamer, Baxter Magolda, &amp;amp; Yue, 2010) among Chinese university students. Two samples of undergraduate students (Stage One, N= 263; Stage Two, N= 663) from three universities in the People’s Republic of China participated in this study. In the first stage, the SA-CDMS was translated from English to Chinese, with the psychometric properties preliminarily examined by exploratory factor analysis and internal consistency test. The original 18-item SA-CDMS model failed to identify the theoretical structures as expected, however, several modifications could be identified from the results of Stage One. In the second stage, the modified SA-CDMS showed acceptable reliability and validity based on the results of confirmatory factor analysis and Cronbach’s alpha coefficients. In addition, Pearson’s correlation analysis was employed by Stage Two to examine the correlations among the demographic factors, three phases, and three dimensions of self-authorship framework. In general, the current study provided evidence for utilizing SA-CDMS in the Chinese higher education context. This study added to the literature of the research on self-authorship and offered practical implications to educators and policymakers in promoting self-authorship development among Chinese university students.
