The Body Shape Questionnaire (BSQ) is a widely used measure of body shape concerns that was originally designed for use with women but has more recently been used with boys and men. The latter use may be problematic, given that no previous study has demonstrated sex invariance for BSQ scores. To determine the extent to which BSQ scores are sex invariant, we asked Portuguese-speaking women ( n = 1,613) and men ( n = 871) to complete the full BSQ (34 items). Confirmatory factor analysis indicated that a hypothesized 32-item model of BSQ scores and shorter versions had acceptable fit indices in women and men, separately. However, multigroup confirmatory factor analysis showed that these BSQ model scores had configural but not metric, scalar, or strict sex invariance. Differential item analysis indicated significant item-functioning differences on 19 of the 32 retained BSQ items. Thus, BSQ scores are not sex invariant, making problematic the results of previous studies that have compared latent BSQ scores across sex.

Multigroup Confirmatory Factor Analysis

This study presents a new approach to synthesizing differential item functioning (DIF) effect size: First, using correlation matrices from each study, we perform a multigroup confirmatory factor analysis (MGCFA) that examines measurement invariance of a test item between two subgroups (i.e., focal and reference groups). Then we synthesize, across the studies, the differences in the estimated factor loadings between the two subgroups, resulting in a meta-analytic summary of the MGCFA effect sizes (MGCFA-ES). The performance of this new approach was examined using a Monte Carlo simulation, where we created 108 conditions by four factors: (1) three levels of item difficulty, (2) four magnitudes of DIF, (3) three levels of sample size, and (4) three types of correlation matrix (tetrachoric, adjusted Pearson, and Pearson). Results indicate that when MGCFA is fitted to tetrachoric correlation matrices, the meta-analytic summary of the MGCFA-ES performed best in terms of bias and mean square error values, 95% confidence interval coverages, empirical standard errors, Type I error rates, and statistical power; and reasonably well with adjusted Pearson correlation matrices. In addition, when tetrachoric correlation matrices are used, a meta-analytic summary of the MGCFA-ES performed well, particularly, under the condition that a high difficulty item with a large DIF was administered to a large sample size. Our result offers an option for synthesizing the magnitude of DIF on a flagged item across studies in practice.

The Worry Domains Questionnaire was proposed as a measure of both pathological and nonpathological worry, and assesses the frequency of worrying about five different domains: relationships, lack of confidence, aimless future, work, and financial. The present study analyzed the factor structure of the long and short forms of the WDQ (WDQ and WDQ-SF, respectively) through confirmatory factor analysis in a sample of 262 students (M age = 21.8; SD = 2.6; 86.3% females). While the goodness-of-fit indices did not provide support for the WDQ, good fit indices were found for the WDQ-SF. Furthermore, no source of misspecification was identified, thus, supporting the factorial validity of the WDQ-SF scale. Significant positive correlations between the WDQ-SF and its subscales with worry (PSWQ), anxiety (STAI-T), and depression (BDI) were found. The internal consistency was good for the total scale and for the subscales. This work provides support for the use of the WDQ-SF, and potential uses for research and clinical purposes are discussed.

The study aimed to perform confirmatory factor analysis, internal consistency, gender differential item functioning, and discriminant validity of the Fear of COVID-5 Scale in emerging adult students of a university in Mexico. Confirmatory factor analysis, internal consistency (Cronbach's alpha and McDonald's omega), and gender differential item functioning were estimated (Kendall tau b correlation). The Fear of COVID-5 Scale showed a one-dimension structure (RMSEA = 0.07, CFI = 0.98, TLI = 0.96, and SRMR = 0.02), with high internal consistency (Cronbach's alpha of 0.78 and McDonald's omega of 0.81), non-gender differential item functioning (Kendall tau b between 0.07 and 0.10), and significant discriminant validity (Higher scores for fear of COVID-19 were observed in high clinical anxiety levels). In conclusion, the Fear of COVID-5 Scale presents a clear one-dimension structure similar to a previous study.

The aim of this study is to develop a scale to measure Turkish reading, listening, speaking and writing self-efficacy of foreign students in Turkey. The sample group of this study consists of 412 foreign students studying in TOMER. At the first phase, four sets of items consisting of 200 items were prepared as a data collecting tool. Eliminating 90 of the items upon expert evaluations, a draft scale consisting of 110 items was applied to mentioned foreign students. The data obtained from the study were analysed by item analysis, exploratory and confirmatory factor analysis methods. At the end of the study, the self-efficacy scale of Turkish reading, writing, speaking and listening skills, which consists of 94 items and targets foreigners who learn Turkish as a foreign language, was found to be a reliable and valid scale. Keywords: Self-efficacy scale, learning Turkish as a foreign language.

Background: Body image shame considerably contributes to the development and persistence of eating and body image disorders. Objectives: The current study was done to determine the psychometric properties of the body image shame scale and introduce a suitable measure for researchers and therapists in the field of psychological health. Methods: In this study, 409 (136 men and 273 females) individuals who referred to cosmetic surgery clinics in Tehran were chosen. The construct validity of the body image shame was assessed using confirmatory factor analysis and divergent and convergent validity. To assess the divergent and convergent validity of the body compassion scale, appearance anxiety inventory, dysmorphic concern questionnaire and Forms of Self-Criticizing/Attacking and Self-Reassuring Scale were used. Internal Consistency and test-retest reliability (4 weeks’ interval) were used to evaluate reliability. LISREL V8.80 and SSPS V20 were used for data analysis. Results: The results of confirmatory factor analysis showed that the two-factor model (internal and external body image shame) fitted the data (RMSEA = 0.07, NFI = 0.94, CFI = 0.92). Body image shame scale had a positive, significant correlation with dysmorphic concern, appearance anxiety, and self-criticism, and a negative, significant correlation with body compassion (P < 0.05). Also, Cronbach’s alpha coefficient, for the whole of scale, internal body image shame, and external body image shame were 0.85, 0.79, and 0.82, respectively. Conclusions: Psychometric properties of the persian version of the body image shame scale were confirmed in this study. Therefore, it can be used as a valid instrument in research and clinical works in populations with concerns about body image.

The aim of this research is confirmatory factor analysis of Aurora-a Battery on Iranian children. Aurora-a Battery is a cognitive assessment according to Robert J. Sternberg’s theory of Successful Intelligence. 400 children 9-12 years old were selected through multi-steps sampling method and were tested with Aurora-a test. These children were from geographically diverse schools in Isfahan city, Iran. The factor analysis of data was performed through Amos software. Fit indices show that data fit with model. Moreover, the correlation between test total score and the analytical, creative and practical intelligences were 0.91, 0.94 and 0.84, respectively. Alpha for Aurora’s total score was equal to 0.92 as well. Aurora-a test can be an appropriate and valid instrument for identification gifted children aged 9-12 according to Sternberg’s theory of successful intelligence. This test allows many children to be identified as gifted which in turn provides the opportunity of further development of their potential.
