In a multi-phase randomized controlled trial, we examine the impacts of cash rewards of EUR 150 and EUR 300 for reducing body weight on the likelihood of weight loss and weight-related behavioral change among 700 obese individuals. We find effects during all experimental phases, including 18 months after exposure to the incentives. Additional monetary rewards of EUR 250 and EUR 500 provided to participants who had lost a substantial amount of body weight exerted only short-term effects.
在一项多阶段随机对照试验中，我们研究了150欧元和300欧元现金奖励对700名肥胖个体减肥可能性及与体重相关行为改变的影响。我们在所有实验阶段都发现了效果，包括接触激励措施18个月后。向体重减轻显著的参与者提供的额外250欧元和500欧元货币奖励仅产生了短期效果。
