Providing material incentives for weight loss is a class of intervention strategies that has received considerable attention; however, the effectiveness of this class of strategies is uncertain. Attending to distinctions among incentive strategies may clarify our understanding of prior work and inform the design of future interventions.
A theoretical framework is proposed that distinguishes between four classes of incentive strategies and is used to organize randomized controlled trials of material incentives for weight loss.
A systematic literature review was conducted.
Findings were mixed with regards to the overall efficacy of material incentives for weight loss. Three of the four proposed incentive categories are represented in the literature. Heterogeneous methods were used across studies rendering comparisons between studies difficult.
Definitive conclusions about the usefulness of material incentives for weight loss could not be drawn. A theoretically grounded approach to designing and testing incentive strategies is encouraged.
提供物质激励以促进减肥是一类备受关注的干预策略；然而，这类策略的有效性尚不确定。关注激励策略之间的区别可以帮助我们理解先前的工作，并为未来的干预措施提供设计依据。
提出了一个区分四类激励策略的理论框架，并用于组织物质激励减肥的随机对照试验。
进行了系统的文献回顾。
物质激励减肥的整体效果存在差异。文献中涵盖了所提出的激励类别中的三类。研究中使用的方法存在差异，使得研究之间的比较变得困难。
不能得出关于物质激励减肥有用性的明确结论。鼓励采用理论基础的方法来设计和测试激励策略。
