Persian Version of Social Appearance Anxiety Scale: A Psychometric Evaluation

Background: Social appearance anxiety refers to the fear of negative evaluation and judgment about appearance in social situations. Previous scales have focused more on body dysmorphic, and a tool that can measure this anxiety in social situations has not been previously introduced. Objectives: This study aimed to investigate the factor structure and psychometric properties of the Social Appearance Anxiety Scale (SAAS) in the student community. Methods: This psychometric study was conducted on a sample of 415 Iranian students in 2020 using the convenience sampling method. The participants completed the Social Physique Anxiety Scale, Body Dysmorphic Scale, and Body Shape Scale. Cronbach's alpha, confirmatory factor analysis (CFA), exploratory factor analysis (EFA), and convergent validity were used to examine internal consistency. The data were analyzed using SPSS software (version 24) and AMOS software (version 21). Results: Cronbach's alpha for total score was 0.95. The relationship between the SAAS and Body Dysmorphic Scale (r = 0.73; P < 0.01), Body Shape Scale (r = 0.46; P < 0.01), and Social Physique Anxiety Scale (r = 0.79; P < 0.01) showed good convergent validity. The EFA extracted one factor that explained 0.60 of the total variance. After testing the one-factor model in CFA, the analysis showed good fitness indexes (comparative fit index = 0.95; goodness of fit index = 0.91). The item-total correlation of the Iranian SAAS was within a range of 0.51 - 0.84. Conclusions: The present scale has a high internal consistency and reliability and can be used for research and evaluation objectives in clinical settings in Iranian society.
