Less than half of adults in the United States (US) obtain the recommended level of physical activity. Social incentives, the influences that impact individuals to adjust their behaviors based on social ties or connections, are ubiquitous and could be leveraged within gamification interventions to provide a scalable, low-cost approach to increase engagement. Gamification, or the use of game design in non-game situations, is commonly used in the real world, but in most cases has not appropriately leveraged principles from theories of health behavior.
We are conducting a four-arm, randomized, controlled trial of 602 overweight and obese adults to evaluate the effectiveness of gamification interventions that leverage insights from behavioral economics to enhance either supportive, competitive, or collaborative social incentives. Daily step counts are monitored using wearable devices that transmit data to the study platform. Participants established a baseline step count, selected a step goal increase, and then were randomly assigned to control or one of three interventions for a 24-week intervention and 12-week follow-up period. To understand predictors of strong or poor performance, we had participants complete validated questionnaires on a range of areas including their personality, risk preferences, social network, and habits relating to physical activity, eating, and sleep. Trial enrollment was conducted in partnership with Deloitte Consulting and included employees from 40 states across the US.
The STEP UP Trial represents a scalable model and interventions found to be effective could be deployed more broadly to increase physical activity.

美国（US）不到一半的成年人达到了推荐的身体活动水平。社会激励是指影响个人根据社会关系或联系调整行为的因素，无处不在，可以在游戏化干预中利用这些因素，提供一种可扩展、低成本的方法来提高参与度。游戏化，即在非游戏情境中使用游戏设计，在现实世界中被广泛应用，但在大多数情况下，并未充分利用健康行为理论中的原则。
我们正在对 602 名超重和肥胖成年人进行一项四臂、随机、对照试验，以评估利用行为经济学见解增强支持性、竞争性或协作性社会激励的游戏化干预措施的有效性。使用可穿戴设备监测日常步数，这些设备将数据传输到研究平台。参与者设定了一个基础步数，选择了一个目标步数增加，然后随机分配到对照组或三个干预组之一，进行 24 周的干预和 12 周的随访。为了了解表现良好或不佳的预测因素，我们让参与者完成了一系列领域的验证问卷，包括他们的个性、风险偏好、社交网络以及与身体活动、饮食和睡眠有关的习惯。试验招募是与德勤咨询公司合作进行的，参与者来自美国 40 个州。
STEP UP 试验代表了一种可扩展的模式，发现有效的干预措施可以更广泛地部署，以增加身体活动。
