Confirmatory factor analysis and psychometric properties of the Persian version of the Multidimensional Body-Self Relations Questionnaire-Appearance Scales (MBSRQ-AS) in women with polycystic ovary syndrome.

Abstract

Body image is a multidimensional and complex psychological construct. Since the Multidimensional Body Self-Relation Questionnaire-Appearance Scale (MBSRQ-AS) is a questionnaire that measures body image as a multidimensional construct. This study aimed to translate and evaluate the psychometric properties of the Persian version of MBSRQ-AS. This methodological study was conducted on 251 women with polycystic ovary syndrome referring to polyclinics of hospitals that were covered by Iran University of Medical Sciences, with age ranging from 18 to 46years old (M = 27.35; SD = 6.32). The mean body mass index (BMI) was 25.59kg/m2 (SD = 4.9). A forward-backward translation procedure was applied. Then face and content validity was inducted. Face and content validity of the Persian MBSRQ-AS was established. Confirmatory factor analyses showed good fit indices for the five-factor structure (appearance evaluation, appearance orientation, body areas satisfaction, overweight preoccupation, and self-classified weight). The internal consistency (Cronbach's alpha ranged from 0.71 to 0.85) and test-retest reliability by calculating the intraclass correlation coefficient ranged from 0.75 to 0.91 was adequate. This study confirms the factor structure of the MBSRQ-AS. The Persian version of MBSRQ-AS has acceptable psychometric properties. Level III, case-control analytic study.
