The effectiveness of acceptance and commitment therapy on improving self-concept, depression, and anxiety in obese women

Abstract

Aims: Obesity can be considered as one of the most complex causes of psychological disorders. Various treatments have been performed to reduce the severity of the disorders in people with obesity. The aim of this study was to evaluate the effectiveness of acceptance and commitment therapy (ACT) on improving self-concept, depression, and anxiety in obese women. Materials and Methods: The present study was a quasi-experimental (pretest and posttest design with control group). The statistical population of the study included all obese women referred to psychological clinics in Mashhad in 2019. Twenty-four obese women were evaluated. Twelve women in the experimental group received eight sessions of ACT and the other 12 women in the control group (waiting list) did not receive any intervention. The results of Beck's self-concept, depression, and anxiety scales were analyzed by multivariate analysis of covariance (MANCOVA). Findings: The results of MANCOVA showed that ACT on the level of self-concept and its components (assessment of mental ability, job efficiency, attractiveness, and social skills) as well as reducing the severity of depression and anxiety is effective (P < 0.001). Conclusion: The ACT can be effective as an appropriate intervention to increase the positive assessment of self-concept and reduce the severity of depression and anxiety in obese women. The implications of the study are discussed.
