Not Applicable
Completed
Conditions
Depression
Obesity
Registration Number
NCT02501239
Lead Sponsor
Dartmouth-Hitchcock Medical Center
Brief Summary

The primary aim of this project is to conduct a randomized controlled pilot study evaluating the feasibility and potential effectiveness of a newly developed combined Health At Every Size and Acceptance and Commitment Therapy (HAES/ACT) treatment, known as Accept Yourself! compared to a commercial behavioral weight loss program, Weight Watchers (WW). Obese women (BMI ≥ 30) with Major Depressive Disorder will be randomly assigned to one of these two treatments. Depression, physical health, and other psychosocial outcomes will be assessed prior to treatment, at post-treatment, and at 3, 6, 9, and 12-month follow up assessments.

Change in self-reported physical activityAt post-treatment (immediately following the three-month intervention) and at 12-month follow-up.
Change in fasting LipidsAt post-treatment (immediately following the three-month intervention) and at 12 month follow-up.
Change in fasting blood glucoseAt post-treatment (immediately following the three-month intervention) and 12 month follow up
Change in eating disorder symptoms, measured by the Eating Disorders Diagnostic Scale (EDDS)At post-treatment (immediately following the three-month intervention) and at 3, 6, 9, and 12-month assessments.
Change in obesity-related quality of life, measured by the Obesity-Related Well-Being Questionnaire (ORWELL97)At post-treatment (immediately following the three-month intervention) and at 3, 6, 9, and 12-month assessments.
Change in obesity stigma, measured by the Weight Self-Stigma Questionnaire (WSSQ)At post-treatment (immediately following the three-month intervention) and at 3, 6, 9, and 12-month assessments.
