Project Health: Enhancing Effectiveness of an Obesity Prevention Program

This 2-site effectiveness trial will test whether a brief dissonance-based obesity prevention program delivered in single sex groups combined with food response and attention training will produce significantly larger weight gain prevention effects than an educational video control condition. An effectiveness trial is important to test whether this program reduces risk for unhealthy weight gain when delivered by real world clinicians under ecologically valid conditions, which is an important step toward broad implementation. A secondary aim focuses on eating disorder symptom prevention effects. A sample of 17-20 year olds with weight concerns (N = 120) will be randomized to single sex Project Health groups with food response and attention training or an educational video control condition. Participants will complete assessments at baseline, posttest, and 6- and 12-month follow ups.
