Obesity And Cash Rewards
通过多阶段随机对照试验，研究了150欧元和300欧元现金奖励对700名肥胖者减重及行为改变的影响，发现激励期间及之后18个月均有效，但额外大额奖励仅短期有效。
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.
