The authors examine the psychometric properties of the Collective Teacher Efficacy Scale (CTES), an instrument designed to measure collective teacher efficacy. Specifically, a multilevel confirmatory factor analysis is used to determine the factor structure of the CTES, comparing one- and two-factor models. The mediating role of the CTES factors…

There has been an exponential increase of interest in the dark side of human nature during the last decade. To better understand this dark side, the authors developed and validated a concise, 12-item measure of the Dark Triad: narcissism, psychopathy, Machiavellianism. In 4 studies involving 1,085 participants, they examined its structural…

The purpose of this study was to validate the Iranian version of the Identity Style Inventory (ISI). Participants were 376 (42% males) university students. Confirmatory factor analyses revealed a clear three-factor structure of identity style and a mono-factor structure of commitment in the overall sample as well as in gender subgroups. Convergent…

Self-Determination Theory specifies the existence of three basic psychological needs: autonomy, competence, and relatedness. The current set of studies (a) provides a narrative review of past research on the Basic Needs Satisfaction in General Scale, (b) examines its dimensionality which has been assumed but not empirically studied, and (c)…

The Texas Revised Inventory of Grief-Present scale (TRIG-Present) is one of the most widely used grief measures; however, researchers have only empirically examined the validity and underlying factor structure of TRIG-Present scores in a few studies. Hence, in the present investigation, we sought to examine the factorial validity of the…

In "Dusky v. United States" (1960), the U.S. Supreme Court articulated 3 abilities that determine a criminal defendant's competence to stand trial: He or she must be able to consult with counsel, have a factual understanding of the proceedings, and have a rational understanding of the proceedings. Although the legal determination of a defendant's…

CEFA 3.02(Browne, Cudeck, Tateneni, & Mels, 2008) is a factor analysis computer program designed to perform exploratory factor analysis. It provides the main properties that are needed for exploratory factor analysis, namely a variety of factoring methods employing eight different discrepancy functions to be minimized to yield initial…

Goldberg's International Personality Item Pool (IPIP; Goldberg, 1999) provides researchers with public-domain, free-access personality measurement scales that are proxies of well-established published scales. One of the more commonly used IPIP sets employs 50 items to measure the 5 broad domains of the 5-factor model, with 10 items per factor. The…

A Metropolis-Hastings Robbins-Monro (MH-RM) algorithm for high-dimensional maximum marginal likelihood exploratory item factor analysis is proposed. The sequence of estimates from the MH-RM algorithm converges with probability one to the maximum likelihood solution. Details on the computer implementation of this algorithm are provided. The…

The purpose of this study is providing a scale for measuring attitudes toward science among Persian secondary school students. A total of 300 (150 girls and 150 boys) of second grade students from all disciplines including science and mathematics in secondary education, participated in the study. Research instrument was, translated Persian version…

The Self-Evaluation Scale--Teacher version, used to assess teacher perceived self-esteem of students, was analyzed. A unidimensional model emerged from exploratory factor analysis, with cautious acceptance of data fit. Reliability and external aspects of validity were supported by the Self-Evaluation Scale--Teacher data.

This study reported the development and validation of the Social Identities and Attitudes Scale (SIAS), a stereotype threat susceptibility measure. Exploratory and confirmatory factor analyses conducted with college students indicate that the scale possesses strong psychometric properties. The SIAS explained 65% of the variance in the items…

The article describes the newly developed Teacher Cultural Beliefs Scale (TCBS). The TCBS assesses multicultural and egalitarian beliefs about diversity, both of which reflect favorable attitudes toward immigrant students, but differ with regard to how cultural diversity is believed to be best accommodated in schools. Results from a first study…

The present study reported on the modification of the Basic Psychological Needs in Exercise Scale (Vlachopoulos & Michailidou, 2006) to assess students' psychological need fulfillment in elementary school, middle school, and high school compulsory physical education classes. Data were collected from 817 5th and 6th grade students, 862 middle…

The aim of this article is to assess the measurement invariance of the Bermond-Vorst Alexithymia Questionnaire (BVAQ) in U.S. Anglo (n = 490) and U.S. Hispanic (n = 379) samples of college students. The BVAQ items demonstrated invariance of the factor loadings, the latent item intercepts, and unique factor variances. However, Hispanics had higher…
