Key Points Question What is the effect of enhancements that target intrinsic vs extrinsic motivation on weight loss outcomes in a primarily digital lifestyle intervention designed specifically for emerging adults? Findings In this randomized clinical trial of 3 adapted behavioral interventions that included 382 emerging adults with overweight or obesity, all 3 interventions led to statistically and clinically significant weight losses in excess of 3% of initial body weight. However, there were no significant differences between the intervention groups. Meaning All 3 adapted behavioral interventions worked well on average and could be used to promote weight management during this vulnerable developmental period, but more work is needed to understand which intervention works best for specific individuals based on sociodemographic and/or psychosocial characteristics.
