Provides a fully flexible approach for orthomax rotation of the core to simple structure with respect to three modes simultaneously. Computationally the approach relies on repeated orthomax rotation applied to supermatrices containing the frontal, lateral, or horizontal slabs, respectively. Exemplary analyses illustrate the procedure. (Author/SLD)

A sufficient condition in terms of the unique variances of a common factor model is given for the results of factor analysis to come closer to those of principal components analysis. In general, vectors corresponding to loading matrices can be related to each other by a specific measure of closeness, which is illustrated. (SLD)

Identifies a general algorithm for orthogonal rotation and shows that when an algorithm parameter alpha is sufficiently large, the algorithm converges monotonically to a stationary point of the rotation criterion from any starting value. Introduces a modification that does not require a large alpha and discusses the use of this modification as a…

In a study of 144 college students, the factorial structure of the Collett?Lester Fear of Death Scale matched the face content of the subscales quite closely, ameliorating the criticism of the scale by R. A. Neimeyer et al. (2003).

The DC-LD is a new classification system providing operationalized diagnostic criteria in recognition of lacking applicability of standard psychiatric criteria for adults with intellectual disability. This study attempts to evaluate internal consistency, inter-rater reliability and factor structure of the Psychopathology Checklists for Adults with…

This article describes the development of a measure of dispositional authenticity and tests whether authenticity is related to well-being, as predicted by several counseling psychology perspectives. Scales were designed to measure a tripartite conception of authenticity, comprising self-alienation, authentic living, and accepting external…

This study evaluated the psychometric properties of the Chinese version of the Social Anxiety Scale for Adolescents (SAS-A) in a sample of 296 adolescents (49% boys) in Grades 7, 8, 9, 10, and 12 with a mean age of 15.52 years. Confirmatory factor analysis replicated the three-factor structure of the SAS-A in the Chinese sample: Fear of Negative…

A considerable amount of attention has occurred with respect to the diagnosis and treatment of Autism Spectrum Disorders (ASDs) of children and youth. Furthermore, the rationale for using the most restrictive of the applied behavior analysis methods and medication has been largely based on the presence of severe challenging behaviors such as…

The Posttraumatic Growth Inventory (PTGI; R. G. Tedeschi & L. G. Calhoun, 1996) was used to measure the growth of university students (N = 347). Results were compared with those of trauma studies and indicate that the PTGI is a general measure of growth suitable for future nontrauma studies. Results reflect a minimal relationship between…

The most widely used instrument to measure alexithymia is the 20-item Toronto Alexithymia Scale (TAS-20). However, different factor structures have been found in different languages. This study tests six published factor models and metric invariance across clinical and non-clinical samples. It also investigated whether there is a method effect of…

The objective of this study is to explore the potential for developing IRT-based working memory scales for assessing specific working memory components in children (8-13 years). These working memory scales should measure cognitive abilities reliably in the upper range of ability distribution as well as in the normal range, and provide a…

In this study, the authors tested the viability of the expanded nigrescence (NT-E) model as operationalized by Cross Racial Identity Scale (CRIS) scores using confirmatory factor analyses. Participants were 594 Black college students from the Southeastern United States. Results indicated a good fit for NT-E's proposed six-factor structure.…

Background: The Strengths and Difficulties Questionnaire (SDQ) is designed to measure psychological adjustment in children and adolescents. Psychometric evaluations of the instrument have shown satisfactory convergent and discriminant validity, while factor analysis studies have shown mixed results across countries. In the present study, the…

The Treatment Motivation Scales for forensic outpatient treatment (TMS-F) is a Dutch 85-item self-report questionnaire for the motivation of forensic outpatients to engage in their treatment and six cognitive and affective determinants of this motivation. Following descriptions of the conceptual basis and construction, the psychometric properties…

Background: Despite the effectiveness of psychotropic treatment for alleviating symptoms of psychiatric disorders, youth adherence to psychotropic medication regimens is low. Adolescent adherence rates range from 10-80% (Swanson, 2003; Cromer & Tarnowski, 1989; Lloyd et al., 1998; Brown, Borden, and Clingerman, 1985; Sleator, 1985) depending on…
