Theory of Change: Understanding Program Goals and Outcomes.
Toolbox Resource
Description
This one-page resource defines a theory of change as the rationale for why prevention activities, services, events, or products should lead to desired outcomes, and notes that theories of change often inform program design and logic models. It briefly describes several common public health theories used for behavior change—such as the Theory of Planned Behavior, Transtheoretical (Stages of Change) Model, Ecological Model, Social Cognitive Theory, and the Health Belief Model. It also emphasizes that selecting an appropriate theory can require domain expertise and recommends consulting a research partner when needed.
