An Integrated Behavior Change Model for Physical Activity
In Brief We present the Integrated Behavior Change Model, a comprehensive multitheory model outlining the psychological factors and processes that impact physical activity behavior. The model integrates hypotheses from social-cognitive, motivational, dual-phase, and dual-systems theories. We provide the theoretical basis for the model and demonstrate its utility in driving future research and developing effective interventions to promote physical activity. The Integrated Behavior Change Model is a comprehensive multitheory model that outlines the psychological factors and processes that determine physical activity.
