This article offers an approach to examining differential item functioning (DIF) under its item response theory (IRT) treatment in the framework of confirmatory factor analysis (CFA). The approach is based on integrating IRT- and CFA-based testing of DIF and using bias-corrected bootstrap confidence intervals with a syntax code in Mplus.

Supervisors evaluated counselors-in-training at multiple points during their practicum experience using the Counseling Competencies Scale (CCS; N = 1,070). The CCS evaluations were randomly split to conduct exploratory factor analysis and confirmatory factor analysis, resulting in a 2-factor model (61.5% of the variance explained).

American Educational Research Association (AERA) standards stipulate that researchers show evidence of the internal structure of instruments. Confirmatory factor analysis (CFA) is one structural equation modeling procedure designed to assess construct validity of assessments that has broad applicability for counselors interested in instrument…

Vocational psychology has generated a number of concepts and assessment instruments considered to reflect ability self-concept (i.e., one's view of one's own abilities) relevant to career development. These concepts and measures often are categorized as either self efficacy beliefs or self-estimated (i.e., self-rated, self-evaluated) abilities.…

Examines the higher order structure of Form G of the Myers Briggs Type Indicator. A third order component analysis of a sample (N=926) found two higher order components. This higher order analysis contributes to the research literature pertaining to the generalized structure of the personality measure. (Contains 44 references and 1 table.) (GCP)

Confirmatory factor analyses suggested that the Mathematics Anxiety Scale for Children measures an internally consistent, unidimensional construct. Construct validity (i.e., correlations with state anxiety, trait anxiety, and quantitative ability) was demonstrated. Discusses the importance of accurately assessing mathematics anxiety at the…

This article describes the development of the Almost Perfect Scale-Revised (APS-R). Exploratory and confirmatory factor analyses and data exploring the reliability and construct validity of the subscales are provided. The results support the existence of three subscales with adequate internal consistencies and promising relationships with other…

The Assessment for Living and Learning (ALL; G.M. Denzine, 1994, 1996) measures college students' perceptions of the academic climate in their residence hall. Confirmatory factor analyses results reveal that the data did not provide an adequate fit to the measurement model underlying the ALL. A revised model was tested and is recommended for use.…
