Abstract
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.
