Understanding the psychological and social drivers of health behaviors is essential for designing effective interventions. This Resource Kit introduces key behavioral models—such as the Health Belief Model, Theory of Planned Behavior, and Transtheoretical Model—and shows how they guide strategies to improve outcomes like vaccination uptake, medication adherence, and lifestyle changes.

The kit also explores how social determinants—like income, education, community environments, and cultural context—influence behavior, and how public health programs can be adapted to address these factors. Additionally, it examines how behavioral economics tools, such as nudges and incentives, can encourage healthier decisions and reduce barriers to action.
