There is a lack of understanding of why childhood physical activity interventions succeed or fail. A model is proposed that relates program process to mediating variables and outcomes. Using the model to design and evaluate interventions could result in a greater understanding of the mechanisms of children's physical activity behavior change and how to tailor programs to them.
