OBJECTIVE The aim of this study is to explore the confirmatory factor analysis results of the Persian adaptation of Statistics Anxiety Measure (SAM), proposed by Earp. METHOD The validity and reliability assessments of the scale were performed on 298 college students chosen randomly from Tabriz University in Iran. Confirmatory factor analysis (CFA) was carried out to determine the factor stru...
The current study assessed the viability of mixture confirmatory factor analysis (CFA) for measurement invariance testing by evaluating the ability of mixture CFA models to identify differences in factor loadings across populations with identical mean structures. Using simulated data from a model with known parameters, convergence rates, parameter recovery, and the power of the likelihood-ratio...
There is continued debate about the appropriateness of Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) for scale evaluation and latent variable modeling more generally. This study seeks to combine the strengths of EFA, namely flexible evaluation of item-factor structures, while using one of the unique strengths of CFA, the simultaneous adjustment for common method bias ...
Background and Objective: Most accidents can be directly attributed to human factors. The aim of this study is to determine the validity and reliability of drivers aberrant behavior questionnaire in urban Bus Company. Materials and Methods: This descriptive study was performed on 168 subjects (in order to exploratory factor analysis) and 161 subjects (for the sake of confirmatory f...
background the 12-item general health (ghq-12) questionnaire is one of the most commonly used instruments in screening studies on mental health. objectives the current study aimed to examine the factor structure of the ghq-12 questionnaire among the students in iran. materials and methods it was a cross-sectional study in which 428 university students were recruited and completed the ghq-12. re...
This article is the second of two on the use of confirmatory factor analysis (CFA) as a method to assess construct validity. The construct validation criteria required by the conventional MTMM approach are satisfied only by certain ideal data sets, such as those in which the method variance of measures is very low. The CFA approach to multitraitmultimethod (MTMM) data is more general, in that v...
Several studies have employed confirmatory factor analysis (CFA) to evaluate the latent structure of posttraumatic stress disorder (PTSD) assessment measures among various trauma-exposed populations. Findings have generally failed to support the current three-factor DSM-IV PTSD conceptualization, demonstrating the need to consider alternative models. The present study used CFA to evaluate seven...
This chapter first reviews the major consequences of ordinal measurement in Confirmatory Factor Analysis (CFA) models and introduces the reader to the Polychoric correlation coefficient, a measure of association designed to avoid these consequences. Next, it presents the results of a Monte Carlo experiment in which the performance of the estimates of a CFA model based on Pearson and Polychoric ...
OBJECTIVE The Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire is a global scale evaluating the impact of upper-extremity disorders. We sought to validate or challenge the unidimensional factor structure of the DASH. METHOD Secondary analysis was performed on data collected from outpatient clinics. Factor analysis was performed in two steps, exploratory factor analysis (EFA) f...
