有大量证据表明，定期的体育锻炼对健康有很多好处。尽管如此，老年人缺乏身体活动的比例仍然很高。本研究旨在确定激励措施是否可以有效地通过提高步行计划的吸收来激励身体活动，无论是否收取报名费以支付相应的费用。一项离散选择联合调查在新加坡对全国老年人进行了抽样调查。每个被调查者都有十对假想的步行方案，并要求他们选择自己喜欢的方案。每种选择在几个方面都有所不同，包括奖励的水平和类型（现金、代金券或健康储蓄信贷）和报名费。对于每个选择，他们都被问及加入他们喜欢的项目的可能性有多大。采用随机实用新型（RUM）对响应进行分析。结果表明，一个为期6个月的免费项目，加上500美元的现金奖励，入学率将达到58.5%；收取50美元的注册费用将这一比例降至55.7%。在激励方式方面，现金支付是最受欢迎的激励方式，但与超市购物券没有显著差异。两者都比医疗储蓄信贷和体育用品代金券更受欢迎。对逆向选择的担忧是最小的，因为在任何提供的项目中，那些不活跃的人至少占新参与者的72%，并且是大多数。研究结果表明，即使是适度的激励措施，也有可能增加不运动的老年人对运动的吸收。此外，尽管现金是最受欢迎的选择，但可能以折扣价购买的超市购物券也是一个接近的选择。研究结果还表明，收取报名费是抵消激励措施成本的可行选择，因为它对参与的影响很小。
There is extensive evidence that regular physical activity confers numerous health benefits. Despite this, high rates of physical inactivity prevail among older adults. This study aimed to ascertain if incentives could be effective in motivating physical activity through improving uptake of walking programs, either with or without an enrolment fee to cover corresponding costs. A discrete-choice conjoint survey was fielded to a national sample of older adults in Singapore. Each respondent was given ten pairs of hypothetical walking programs and asked to choose the option they preferred. Each option varied along several dimensions, including the level and type (cash, voucher, or health savings credit) of incentive and an enrolment fee. For each option, they were asked how likely they would be to join their preferred program. A random utility model (RUM) was used to analyze the responses. Results suggest that a free 6-month program with a $500 cash incentive would generate enrolment rates of 58.5%; charging $50 to enroll lowers this to 55.7%. In terms of incentive type, cash payments were the most preferred incentive but not significantly different from supermarket vouchers. Both were preferred to health savings credits and sporting goods vouchers. Concerns of adverse selection were minimal because those who were inactive represented at least 72% of new participants for any offered program(s) and were the majority. Study results demonstrate the potential for even modest incentives to increase program uptake among inactive older adults. Moreover, although cash was the most preferred option, supermarket vouchers, which could potentially be purchased at a discount, were a close alternative. Results also suggest that an enrolment fee is a viable option to offset the costs of incentives as it has only minimal impact on participation.
