Nourian, L., Aghaei, A., & Ghorbani, M. (2015). The efficacy of acceptance and commitment therapy on weight self-efficacy lifestyle in obese women. Journal of Mazandaran University of Medical Sciences, 25(123), 159-169.
Background and purpose: Studies have shown that increasing self-efficacy could predict the treatment success for weight loss. This study assessed the efficacy of Acceptance and Commitment Therapy (ACT) on weight self-efficacy lifestyle in obese women in Isfahan. Materials and methods: A quasi-experimental pretest/post-test control group design was conducted on all obese women (BMI≥30) in Isfahan in spring 2014. Convenience sampling was performed and 30 obese women were selected according to our defined inclusion criteria. They were randomly assigned either in a control or experimental group (n=15 per group). The Weight Efficacy Lifestyle Questionnaire was completed by the participants in pre-test, post-test and follow-up stages. The experimental group attended ACT classes for 8 sessions/ 90 min. Results: Significant differences were found in weight self-efficacy lifestyle in all subscales including food availability, social pressure, physical discomfort, negative emotions, and positive activities in experimental group during all stages. Conclusion: According to this study, ACT could improve weight self-efficacy lifestyle as a predicting index of weight loss in obese women. Therefore, this treatment could be beneficial when performed in conjunction with other weight loss interventions.
