A transdisciplinary approach incorporating biological, psychological, behavioral, and genetic factors was taken to better identify proposed moderators of the effectiveness of an intervention to increase physical activity. This paper illustrates how theory-based individual difference variables can be integrated into a complex randomized controlled trial. The transdisciplinary framework guiding the selection of moderators, the COSTRIDE intervention study and sample, and the relationships among baseline variables are provided. Participants were non-active individuals randomly assigned to either the STRIDE exercise or health-and-wellness contact control condition. Structural equation modeling was utilized to demonstrate that relationships among baseline variables confirm hypothesized relationships in the transdisciplinary framework. Preliminary data from COSTRIDE suggest that interventions among sedentary individuals may be more effective if a broader range of factors influencing physical activity are considered.
采用跨学科方法，综合考虑生物学、心理学、行为学和遗传学因素，以更好地确定干预措施增加身体活动效果的拟议调节因素。本文说明了如何将基于理论的个体差异变量整合到复杂的随机对照试验中。提供了指导调节因素选择的跨学科框架、COSTRIDE 干预研究和样本，以及基线变量之间的关系。参与者是非活跃个体，随机分配到 STRIDE 运动或健康和福利联系对照组。结构方程模型用于证明基线变量之间的关系证实了跨学科框架中的假设关系。COSTRIDE 的初步数据表明，如果考虑影响身体活动的更广泛因素，针对久坐不动个体的干预措施可能更有效。
