Factor Structure and Reliability of the Persian Version of Body Esteem Scale Among Iranian Adults: Exploratory Graph Analysis Approach.

Background and Purpose: The present study aimed to examine the psychometric properties of the Persian version of the Mendelson and White Body Esteem Scale in Iranian adults. Methods: This cross-sectional study design was used and carried out in 2023. Following the inclusion criteria, 500 adults were gathered from Tehran (Tehran, Iran) with an accessible sampling method. After translation of Body Esteem Scale to Persian language, construct validity (with factor analysis and exploratory graph analysis) and reliability were assessed. Results: The mean age of the participants was 30.66 (standard deviation = 7.40) years. The results of Maximum Likelihood Exploratory Factor Analysis (MLEFA) with Promax with Kaiser normalization rotation extracted three factors accounting for 43.4% of the variance comprising 21 items. Also, after necessary modifications during confirmatory factor analysis, the final model was approved. As for construct reliability, the Cronbach's alpha, Composite Reliability, and Maximal Reliability for all constructs were greater than 0.7, demonstrating good internal consistency and construct reliability. Conclusions: According to results, the Persian version of Body Esteem Scale has a valid structure and acceptable reliability. This scale can be used by health professionals in many ways.
