Final answer:
The Transtheoretical Model (TTM), also known as the Stages of Change Model, is the health behavior theory/model that consists of five stages.
Step-by-step explanation:
The health behavior theory/model that consists of five stages of change is the Transtheoretical Model (TTM), also known as the Stages of Change Model. The TTM proposes that individuals go through five stages when making behavior changes:
- Precontemplation: not yet considering change
- Contemplation: considering change but not yet taking action
- Preparation: getting ready to take action
- Action: making the change
- Maintenance: maintaining the change over time
Each stage represents a different level of readiness and commitment to change. The TTM is commonly used in health promotion and behavior change interventions to understand and guide individuals through the process of making positive health behavior changes. For example, it can be applied to help individuals quit smoking, start exercising, or adopt a healthier diet.
