在健康的生活方式干预中使用物质奖励正变得越来越普遍。然而，自我决定理论（SDT）认为，当物质激励被视为控制时，它们会破坏内在动机。我们分析了“做出更好的选择”试验的数据，该试验测试了改善四种风险行为的策略：低水果蔬菜摄入量，高饱和脂肪摄入量，低体力活动和高久坐活动。在基线时，参与者报告了经济激励是重要激励因素（经济激励）的程度;在3周激励阶段之前和之后评估了自我报告的每种行为的享受。与SDT一致，在控制了一般动机和组分配后，较低的财务动机预测了更多的适应性变化的享受。而参与者低的金融动机经历了适应性变化，适应性变化被抑制在那些高的金融动机。
The use of material incentives in healthy lifestyle interventions is becoming widespread. However, self-determination theory (SDT) posits that when material incentives are perceived as controlling, they undermine intrinsic motivation. We analyzed data from the Make Better Choices trial-a trial testing strategies for improving four risk behaviors: low fruit-vegetable intake, high saturated fat intake, low physical activity, and high sedentary activity. At baseline, participants reported the degree to which financial incentives were an important motivator (financial motivation); self-reported enjoyment of each behavior was assessed before and after the 3-week incentivization phase. Consistent with SDT, after controlling for general motivation and group assignment, lower financial motivation predicted more adaptive changes in enjoyment. Whereas participants low in financial motivation experienced adaptive changes, adaptive changes were suppressed among those high in financial motivation.
