There is a lack of research on the effects of outliers on the decisions about the number of factors to retain in an exploratory factor analysis, especially for outliers arising from unintended and unknowingly included subpopulations. The purpose of the present research was to investigate how outliers from an unintended and unknowingly included…

This article examines the psychometric structure of the Anxiety Control Questionnaire (ACQ) in Chinese adolescents. With the data collected from 212 senior high school students (94 females, 110 males, 8 unknown), seven models are tested using confirmatory factor analyses in the framework of the multitrait-multimethod strategy. Results indicate…

As part of Phase 3 of the Universal Preschool Child Outcomes Study (UPCOS-3), Mathematica Policy Research worked with the First 5 LA Children and Families Commission and Los Angeles Universal Preschool (LAUP) to conduct a descriptive study of the characteristics of classrooms in LAUP programs during winter 2010. This study has a particular focus…

This research was undertaken to determine the factor structure of the 26-item revised versions of the Mehrabian (1968) Female and Male scales, a self-report instrument designed to measure achievement motivation. (Author/RK)

Examined the factor structure of the Counselor Rating Form (CRF). Real clients (N=110) completed the CRF at the conclusion of counseling. The results suggest the existence of only one major factor underlying clients' perceptions of counselors. The one-factor model performed as well as the three-factor model. (Author/JAC)

Uses exploratory factor-analysis and confirmatory factor-analysis to identify and cross-validate the factorial structure underlying two group intelligence tests and two group-Piagetian tests. Establishes a high degree of overlap between Piagetian and psychometric intelligence tests, most likely because both types of test appear to measure…

The factorial structure of the Rotter Internal-External (IE) scale was examined. While there was strong evidence against the unidimensionality of the Rotter scale, the findings suggested that the first-order factors do define a single higher-order construct that may represent the generalized IE construct. (Author/LMO)

The study examined the component structure of the Relational Health Indices (B. Liang et al., 2002) with a mixed-sex sample of students seeking services at a university counseling center. In contrast to previous findings, results suggested a unidimensional structure for the peer and mentor composites and a 2-component structure for the community…

This investigation: (1) tested the ability of an a priori hierarchical structure of self-concept derived from the Shavelson model to explain responses to the Self Description Questionnaire III (SDQ III); and (2) demonstrated the application and problems with the use of hierarchical confirmatory factor analysis. A first-order factor analysis…

The latent structure, reliability, and item discrimination of 33 items on a Centers for Disease Control (CDC) instrument representing knowledge, attitudes, and beliefs about the acquired immune deficiency syndrome (AIDS) were assessed. The study sample included 311 adolescents ranging from ages 12 to 19 years. Demographic characteristics of the…
