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.
