The assumptions of the model for factor analysis do not exclude a class of indeterminate covariances between factors and error variables (Grayson, 2003). The construction of all factors of the model for factor analysis is generalized to incorporate indeterminate factor-error covariances. A necessary and sufficient condition is given for…

For two given vectors of the three-dimensional Euclidean space we investigate the problem of identifying all rotations that transform them into each other. For this purpose we consider three types of rotation matrices to obtain a complete characterization. Finally some attention is paid to the problem of obtaining all rotations taking two vectors…

A key feature of autism is restricted repetitive behavior (RRB). Despite the significance of RRBs, little is known about their phenomenology, assessment, and treatment. The Repetitive Behavior Scale-Revised (RBS-R) is a recently-developed questionnaire that captures the breadth of RRB in autism. To validate the RBS-R in an independent sample, we…

This article describes the development of the Comprehensive Assessment of Team Member Effectiveness. The authors used the teamwork literature to create potential items, which they tested using two surveys of college students (Ns = 2,777 and 1,157). The authors used exploratory factor analysis and confirmatory factor analysis to help them select…

Psychopaths represent a significant management challenge in a prison population. A sample of ninety-five male inmates from three medium security prisons was tested using the Hare Psychopathy Checklist: Screening Version (PCL:SV). Using traditional criteria, 22% of the inmates were classified as psychopaths. Scores on the two factor dimensions of…

To examine the convergent and discriminant validity of the scales on the "Developmental Indicators for the Assessment of Learning-Third Edition" [DIAL-3; Mardell-Czudnowski, C., and Goldenberg, D.S. (1998). "Developmental indicators for the assessment of learning-third edition." Circle Pines, MN: American Guidance Service,…

The science of education has focused on alternative educational approaches for years with a view to meeting the needs of wide student audiences in classes. One of the sources of the differences in learning performance at class environment is the learning styles. This study has been conducted to develop a learning styles scale for students at the…

Although counseling expectations have been studied in late adolescent and adult samples, little is known about younger adolescents' openness to counseling and perceptions of the counseling process. In this study, 329 middle school students completed the Expectations About Counseling Questionnaire-Brief Form (Tinsley, 1982). An exploratory factor…

The State-Trait Inventory for Cognitive and Somatic Anxiety (STICSA; M. J. Ree, C. MacLeod, D. French, & V. Locke, 2000) was designed to assess cognitive and somatic symptoms of anxiety as they pertain to one's mood in the moment (state) and in general (trait). This study extended the previous psychometric findings to a clinical sample and…

A taxometric analysis of the Psychopathy Checklist: Screening Version (PCL:SV; S. D. Hart, D. N. Cox, & R. D. Hare, 1995) was performed on a group of 2,250 male and female forensic/psychiatric patients and jail/prison inmates. The 4 PCL:SV facet scores (Interpersonal, Affective, Impulsive Lifestyle, Antisocial Behavior) served as indicators in…

Bryant and Smith [(2001). Refining the architecture of aggression: A measurement model for the Buss-Perry Aggression Questionnaire. "Journal of Research in Personality," 35, 138-167] refined the 29-item Aggression Questionnaire and obtained a 12-item short form of the AQ that has yet to be validated with samples outside of North America…

Developmental theories presume dramatic differences in the coping of the young and old, but with little empirical support. In this study, five demographically matched groups: Pre-Teens (9-12 years, n = 153), Early Teens (13-15, n = 141), Late Teens (16-18, n = 151), Younger Adults (20-29, n = 133), and Older Adults (30-70, n = 133) completed…

Although there is no agreement as to what instructional interactivity and interaction mean in educational literature, researchers agree that both terms are vital for teaching and learning one way or another. This paper presents the item-development stages and validity and reliability analyses of the Interactivity Survey (IS), which attempts to…

Based on a synthesis of the literature in inductive reasoning, a framework for prescribing and assessing mathematics inductive reasoning of primary school students was formulated and validated. The major constructs incorporated in this framework were students' cognitive abilities of finding similarities and/or dissimilarities among attributes and…

The factor structure of a Chinese version of the Zarit Burden Interview was assessed with a random sample of Chinese caregivers in Canada. The results indicated that the latent constructs identified in earlier studies on caregivers did not fit well when tested with Chinese caregivers. Exploratory factor analysis reported a five-factor solution,…
