Drs. Weinstock and Petry note that behavior change is complex and reinforcement is an important component of interventions to increase physical activity. Although we agree with these comments, our study focused on the effect of different ways to frame financial incentives. Our findings show that, holding reinforcement constant, financial incentives framed as a loss were most effective. A prior study by Drs. Weinstock and Petry revealed important insights but should be compared with our study with caution, because theirs was smaller, did not target overweight and obese adults, used a different step goal, and had a different primary outcome measure (1).
