Trial Summary

What is the purpose of this trial?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.

Eligibility Criteria

This trial is for 17-20 year olds who are concerned about their weight, believe they can improve their diet and exercise habits, and have a BMI between 20 to 30. It's not for those with anorexia, bulimia, binge eating disorder or past participants in Project Health studies.

Inclusion Criteria

I am between 17 and 20 years old.

Exclusion Criteria

I have been diagnosed with an eating disorder.

Treatment Details

The study tests if a dissonance-based obesity prevention program combined with food response training beats an educational video at preventing weight gain. Participants will be randomly placed into groups and followed up over a year.
