Body Image Disturbance, Overweight and Obesity, Weight Loss
Conditions
Brief summary
This study is a randomized controlled trial to evaluate the effect of an adapted version of the Body Project program among adult women of higher body weight who want to lose weight. The study will evaluate treatment effects on weight and shape concern and explore the impact of intervention on weight loss outcomes.
Detailed description
The objective of this study is to conduct a randomized controlled pilot trial to test the effects of a 28-week treatment protocol that combines a modified body image intervention (The Body Project: weeks 1-4) with a 6-month standard behavioral weight management treatment (weeks 5-28). The combined protocol will be evaluated in comparison to a control group that receives an education only program during weeks 1-4 followed by the same 6-month weight management treatment. It will be tested among women with high body weight who report High Weight and Shape Concern and would like to lose weight. The goals of the study are: 1. To evaluate effects of a manualized intervention on Weight and Shape Concern prior to starting weight management. 2. To evaluate the effects of the modified Body Project intervention on momentary weight/shape-related thoughts and overeating episodes during behavioral weight management. 3. To conduct exploratory analyses comparing effects of the two treatment conditions on weight loss and other weight-related behaviors (e.g., exercise, adherence to self-monitoring).
Interventions
BEHAVIORALModified Body Project
The Body Project, an evidence-based body image intervention developed for young women at risk for eating pathology, was adapted for use among adult women with high weight and shape concern and high body weight who want to lose weight.
BEHAVIORALFacts about obesity, myths about weight loss
This intervention is designed to help individuals prepare for weight loss and is focused on facts about obesity, myths about weight loss, and the importance of a varied diet.
BEHAVIORALLifestyle intervention for weight loss
This 24-week behavioral weight management program is based on the Look AHEAD and Diabetes Prevention Program manuals. It is designed to facilitate 7-10% weight loss of initial body weight through dietary and physical activity changes with use of behavioral strategies to support lifestyle changes over time.
