Health Behavior Change

Shrink Definition

Health behavior change is the process of initiating, maintaining, or discontinuing behaviors that influence physical or mental health. Behavior change rarely depends upon motivation alone. It reflects interactions among biological, psychological, social, environmental, and cultural influences. Successful behavior change often develops gradually through repeated adjustments rather than dramatic transformation.
