Zhang and Savalei proposed an alternative scale format to the Likert format, called the Expanded format. In this format, response options are presented in complete sentences, which can reduce acquiescence bias and method effects. The goal of the current study was to compare the psychometric properties of the Rosenberg Self-Esteem Scale (RSES) in…

A Monte Carlo study was conducted to compare the performance of a level-specific (LS) fit evaluation with that of a simultaneous (SI) fit evaluation in multilevel confirmatory factor analysis (MCFA) models. We extended previous studies by examining their performance under MCFA models with different factor structures across levels. In addition,…

A number of psychometricians have argued for the use of parallel analysis to determine the number of factors. However, parallel analysis must be viewed at best as a heuristic approach rather than a mathematically rigorous one. The authors suggest a revision to parallel analysis that could improve its accuracy. A Monte Carlo study is conducted to…

The present study evaluates a prospective observer form of the Coping Inventory for Stressful Situations (CISS) by comparing the two forms in terms of factor structure, mean differences, reliability, and examining correlations between self-report and peer ratings. A total of 163 pairs of friends complete the CISS and an observer form of the CISS.…

This study assessed the accuracy of parallel analysis, a technique in which observed eigenvalues are compared to eigenvalues from simulated data when no real factors are present. Three studies with manipulated sizes of real factors and sample sizes illustrate the importance of modeling the data more closely when parallel analysis is used. (SLD)

Study was undertaken to determine the degree to which the EPPS, CPI, and 16 PF scales are correlated with the EPI scales and to determine the degree to which the scales in all four inventories are measuring the same common traits. (Authors)

Whether the one- or two-factor Wechsler or weighted sum scores (WSS) structural models adequately fit the Wechsler Intelligence Scale for Children III (WISC-III) covariance matrices was studied with samples of 2200 and 1118 children from previous studies. Both the WSS and supplemented models provided better fit than Wechsler's model but still…

The Little Jiffy" consists of principal components analysis and varimax rotation of all components with eigenvalues greater than one. (DG)

A computer program designed to compare factors from similar concept matrices (person by scale) obtained at different times is presented. (PR)

This study examined whether the original factor structure of the Parent Success Indicator (PSI) could be replicated with scores from generational views on both the English- and Mandarin-language versions of the instrument. The 60-item PSI was evaluated using responses from 840 Taiwanese parents (n = 429) and their 10- to 14-year-old adolescents (n…
