The Health Activation Process: An autonomy-supportive coaching model for facilitating sustainable active living.

This article presents the Health Activation Process (HAP), a new four-stage transtheoretical framework designed to support physical activity (PA) behavior change within health coaching contexts. HAP emphasizes leveraging individuals' past positive experiences, future aspirations, readiness for change, and social-material resources to foster autonomous motivation and enjoyment in PA, addressing the persistent global issue of physical inactivity despite widespread awareness of its benefits. The model's stages—Reflect, Project, Inspect, and Connect—guide clients through exploring affective associations with PA, envisioning healthy aging goals, assessing physical and psychological readiness, and mapping supportive ecosystems. While theoretically and empirically informed, HAP's effectiveness as an intervention remains to be empirically validated, with future research suggested to evaluate its impact compared to more prescriptive approaches and to refine its components.
