The Together Everyone Achieves More Physical Activity (TEAM-PA) trial is a randomized controlled trial testing the efficacy of a group-based intervention for increasing physical activity (PA) among insufficiently active African American women.
The TEAM-PA trial uses a group cohort design, is implemented at community sites, and will involve 360 African American women. The trial compares a 10-week group-based intervention vs. a standard group-delivered PA comparison program. Measures include minutes of total PA/day using 7-day accelerometer estimates (primary outcome), and body mass index, blood pressure, waist circumference, walking speed, sedentary behavior, light physical activity, and the percentage achieving ≥150 min of moderate to vigorous PA/week (secondary outcomes) at baseline, post-intervention, and 6-months post-intervention.
The intervention integrates elements from Social Cognitive Theory, Self-Determination Theory, Group Dynamics Theory, and a focus on collectivism to evaluate different components of social affiliation (relatedness, reciprocal support, group cohesion, and collective efficacy). The intervention integrates shared goal-setting via Fitbits, group-based problem-solving, peer-to-peer positive communication, friendly competition, and cultural topics related to collectivism. Compared to the standard group-delivered PA program, participants in the intervention are expected to show greater improvements from baseline to post- and 6-month follow-up on minutes of total PA/day and secondary outcomes. Social affiliation variables (vs. individual-level factors) will be evaluated as mediators of the treatment effect.
The results of the TEAM-PA trial will determine the efficacy of the intervention and identify which aspects of social affiliation are most strongly related to increased PA among African American women.

“全民共同实现更多身体活动”（TEAM-PA）试验是一项随机对照试验，旨在测试基于小组的干预措施在提高身体活动（PA）方面对非活跃的非裔美国女性的有效性。
TEAM-PA 试验采用小组队列设计，在社区站点实施，将涉及 360 名非裔美国女性。试验比较了为期 10 周的基于小组的干预与标准小组提供的 PA 比较计划。测量包括使用 7 天加速度计估计的每天总 PA 分钟数（主要结果），以及体重指数、血压、腰围、步行速度、久坐行为、轻度体力活动以及达到≥150 分钟中度至剧烈 PA/周的百分比（次要结果）在基线、干预后和干预后 6 个月。
该干预措施整合了社会认知理论、自我决定理论、群体动态理论以及对集体主义的关注，以评估社会联系的不同组成部分（相关性、相互支持、群体凝聚力和集体效能）。该干预措施整合了通过 Fitbits 进行共同目标设定、基于小组的解决问题、同伴之间的积极沟通、友好竞争以及与集体主义相关的文化主题。与标准小组提供的 PA 计划相比，预计干预组的参与者在总 PA 分钟数和次要结果的基线到干预后和 6 个月随访期间会有更大的改善。社会联系变量（与个体因素相比）将作为治疗效果的中介进行评估。
TEAM-PA 试验的结果将确定干预措施的有效性，并确定社会联系的哪些方面与非裔美国女性的 PA 增加最相关。
本研究于 2022 年 8 月在 Clinicaltrials.gov 上注册（#NCT05519696），在最初参与者入组之前。
