The purpose of the present study was to investigate the psychometric properties of the Persian version of the FAAQ in people who engaged in weight loss or weight loss maintenance. In this descriptive study, 420 men and women were selected through consecutive sampling. They respond to the FAAQ and the Self-compassion Scale (SCS). To assess the validity of the questionnaire, construct validity (exploratory factor analysis and confirmatory factor analysis) and convergent validity was used. The reliability of the questionnaire was assessed via internal consistency. Exploratory factor analysis of the FAAQ’s items revealed two factors named willingness and acceptance, but, at the item level, it was different from the original model of the questionnaire. For two extracted factors, Cronbach’s alphas range was 0.73 to 0.74 suggesting satisfying reliability of the Persian version of the FAAQ. Confirmatory factor analysis supported the original two factor model of the questionnaire, and fit indices indicated a good model fit. The convergent validity of the questionnaire was also adequate. The Persian version of the FAAQ has adequate reliability and validity in Iranian society and is a good self-report for research and clinical settings.

The purpose of this study was construct and validate a questionnaire to measure personal epistemology in children. Accordingly, the 44 question with Likert scoring method was designed to have three options. Face and content validity was assessed through the survey of 10 experts and its reliability, through the implementation of 50 students to retest interval of one month, was calculated 0/72. Then, the questionnaire was administered on 472 students (217 males and 255 females) and using factor analysis with varimax rotation method revealed five factors with higher eigenvalues: simple knowledge, certain knowledge, source of knowledge, product of knowing and justification of knowing. In order to determine validity and reliability of the scale respectively, confirmatory factor analysis and Cronbach alpha coefficients were used. Results of Confirmatory factor analysis showed a good fit to the proposed five-factor structure. Also, the total score for internal consistency through Cronbach’s alpha, was 0/85. According to the results, the scale has acceptable reliability and validity and can be used as an applicable instrument in assessing personal epistemology in children.
