This study examined the effect of technology-based group contingency on walking among adults and compared the effectiveness and cost-efficiency between three types of contingency. Seventy-two students were divided into teams of three. Each team was randomly assigned to one of three group contingency conditions (independent, interdependent, or dependent), undergoing 66 days of technology-based group contingency intervention. Sixty-five participants completed the intervention and 61 completed the follow-up assessment two months later. Step counts and self-reported walking activity increased after the intervention under all three conditions. The proportion of participants meeting the target step counts was significantly higher under the dependent group contingency condition. However, intervention effects were not maintained two months later under any condition. For cost-efficiency, increases in step count per point were significantly greater under the interdependent group contingency condition. Group cohesion and social validity (point satisfaction and point utility) were significantly higher under the dependent group contingency condition. Finally, the clinical implications and limitations of this study are discussed.

团体意外事件类型对步行的影响：效果和成本效率比较


本研究探讨了基于技术的团体应急措施对成人步行的影响，并比较了三种应急措施的有效性和成本效益。七十二名学生被分成三人一组。每个团队被随机分配到三个小组应急条件之一（独立、相互依赖或依赖），接受为期 66 天的基于技术的小组应急干预。 65 名参与者完成了干预，61 名参与者在两个月后完成了后续评估。在所有三种情况下进行干预后，步数和自我报告的步行活动均有所增加。在依赖群体应急条件下，达到目标步数的参与者比例明显更高。但两个月后，无论何种情况，干预效果均未能维持。就成本效率而言，在相互依赖的群体应急条件下，每点步数的增加显着更大。在依赖群体应急条件下，群体凝聚力和社会效度（积分满意度和积分效用）显着更高。最后，讨论了本研究的临床意义和局限性。
