This study in this article investigated how school counselors and principals perceive their professional relationship. Q methodology was used to develop 45 opinion statements about the relationship between school counselors and principals, and 39 professional school counselors and principals then sorted the statements. Four factors emerged…

The purpose of this study was to examine the dimensionality of the "Contact With Disabled Persons Scale" (CDP). An exploratory factor analysis of the CDP yielded three factors: General Interpersonal Contacts, Positive Contact Experiences, and Negative Contact Experiences. A confirmatory factor analysis provided further evidence for the stability…

The factor structure of the Autism Diagnostic Interview-Revised (ADI-R) algorithm items was examined using exploratory (EFA) and confirmatory factor analyses (CFA) factor methods. The ADI-R was completed for 1,170 youths and adults (ages 2-46). Results of EFAs indicated strong support for two-factor structure, with social communication and…

The present study investigated the reliability and factor structure of scores on a 12-item version of Phinney's multigroup ethnic identity measure with an Australian sample from diverse cultural backgrounds. Participants were 485 students aged between 10 and 15 years. The results generally supported the reliability of the ethnic identity scale…

Objective: This study describes the development and validation of a perceived social competence scale that social workers can easily use to assess children's and youth's social competence. Method: Exploratory and confirmatory factor analyses were conducted on a calibration and a cross-validation sample of youth. Predictive validity was also…

Kaiser's measure of sampling adequacy is applied to a special Spearman matrix and a special q cluster generalization. The result supports the contention that the measure should be no less than five tenths for data to be appropriate for factor analysis. A table is presented. (Author/JKS)

Studies concerning the relation of sample size to the number of variables in factor analysis are reviewed. It is noted that constraints imposed on the dimensionality of the variables by having fewer observations than variables are not mentioned in the literature. Suggestions for resolution of the problem are made. (Author/JKS)

Matching by Procrustes methods involves the transformation of one matrix to match with another. A special least squares criterion, the congruence coefficient, has advantages as a criterion for some factor analytic interpretations. A Procrustes method maximizing the congruence coefficient is given. (Author/JKS)

Recent research and theory suggest narcissistic features contribute to aggression in adults. The present study examined the association of narcissistic features with aggression and internalizing symptoms in 233 students of 5th-8th grade at three inner-city schools. A factor analysis of the Narcissistic Personality Inventory in this sample revealed…

Perceived security is defined as the level of security that users feel while they are shopping on e-commerce sites. The aims of this study were to determine items that positively influence this feeling of security by users during shopping, and to develop guidelines for perceived security in e-commerce. An experiment allowed users with different…

The purpose of this study of teacher attitudes and school climate was to identify the intrinsic and extrinsic motivators affecting veteran teachers' decision to remain in the profession. The study was conducted using data collected by the National Center for Education Statistics from a survey administered during the 2003-2004 school year to…

This study examined the relationship between individual and family perfectionism and mental health functioning among two hundred and seven Latino college students. One aim of this study was to test the factor structure of the Almost Perfect Scale-Revised (APS-R; Slaney, Rice, Mobley, Trippi, & Ashby, 2001) with Latino college students by…

It is only relatively recently that empirical research has begun to emerge that has sought to further understand the factors that may contribute to the educational inequities between Indigenous Australian and non-Indigenous Australian students. Although it has been argued that research has typically employed small, unrepresentative case studies…

Background: Although structured interviews are assumed to be scientifically superior to checklists for measuring youth psychopathology, few studies have tested this hypothesis. Interviews place a much greater burden on respondents, making it critical to determine their added value when quantifying psychiatric symptoms. Methods: Confirmatory factor…

The College Learning Effectiveness Inventory, a new assessment tool identifying personal variables important to college student success, was constructed using empirical approaches grounded in a conceptual model. The exploratory and confirmatory studies revealed the six-underlying factors: Academic Self-Efficacy, Organization and Attention to…
