Acceptance and commitment therapy interventions demonstrate efficacy for weight loss. ACT-based workshops represent an innovative and potentially scalable application of this approach to obesity treatment. 70 women will be recruited to participate. Half of the participants (n = 35) will receive a brief ( approximately 4-hour) workshop that aims to facilitate the development and maintenance of healthy lifestyle behaviors using ACT principles such as valued living and committed action. Outcomes will be assessed at baseline, 1-week, and 1-month post-intervention.
The goal of this clinical trial is to investigate if a 4-hour acceptance and commitment therapy workshop can help the adoption and maintenance of healthy lifestyle behaviors in women with obesity. The objectives are as follows:~To assess changes in ACT-related constructs before and after the workshop~To assess changes in other psychological constructs that have been shown to hinder successful weight management before and after the workshop~To assess changes in dietary and physical activity behaviors before and after the workshop. Participants will complete baseline questionnaires and anthropometric measures at three time points: baseline, 1 week after the workshop, and 1 month after the workshop. Researchers will compare an active intervention group to a waitlist control group to investigate the efficacy of the workshop.
