作为公共卫生举措的一部分，激励措施是鼓励健康行为的有用工具。然而，人们仍然担心动机挤出——在激励措施被取消后，采取某种行为的动机水平会下降到基线水平以下——而且很少有公共卫生研究对动机挤出进行评估。在这里，我们评估了通过抽签确定动机挤出以促进参与恰加斯病媒介控制活动的可行性。我们在随后参与相同行为、相关行为和不相关行为时寻找排挤的证据。我们发现了相同行为的潜在动机被挤出，但在抽奖激励被取消后，相关行为或不相关行为却没有被挤出。尽管存在一些局限性，我们得出的结论是，在大规模激励试验中评估激励挤出是可行的。
Incentives are a useful tool in encouraging healthy behavior as part of public health initiatives. However, there remains concern about motivation crowd out—a decline in levels of motivation to undertake a behavior to below baseline levels after incentives have been removed—and few public health studies have assessed for motivation crowd out. Here, we assess the feasibility of identifying motivation crowd out following a lottery to promote participation in a Chagas disease vector control campaign. We look for evidence of crowd out in subsequent participation in the same behavior, a related behavior, and an unrelated behavior. We identified potential motivation crowd out for the same behavior, but not for related behavior or unrelated behaviors after lottery incentives are removed. Despite some limitations, we conclude that motivation crowd out is feasible to assess in large-scale trials of incentives.
