Background: The present study aimed to investigate the psychometric properties of the Persian version of the weight-related experiential avoidance (AAQW) in overweight and obese treatment seeker in the clinical setting.
Methods: This sample consists of 220 male and female overweight or obesity treatment seeker from Overweight and obesity centers who agreed to fill out the self-reported measures.
Results: Confirmatory factor analysis (CFA) supported 3-factor structures of AAQW, including (weight as a barrier to living, Food as Control, and weight-stigma). Furthermore, the internal consistency of AAQW indicates an acceptable range (α = .70); Also, expected associations between AAQW and external correlates (e.g., BES, AAQ-II, KIMS, BDI-II, and CFQ) supported the measure's convergent validity in a sample of overweight and obese treatment seeker in the clinical setting.
Conclusions: Overall, our study offers that the Persian version of weight-related experiential avoidance has psychometrically valid and reliable tools to assess experiential avoidance. Furthermore, weight-related experiential avoidance is associated with higher severity of binge eating symptoms, higher psychological inflexibility levels, experiential avoidance, and more cognitive fusion and depression symptomology.
