Final answer:
The Transtheoretical Model (TTM) and The Precaution Adoption Process Model (PAPM) are stage models that describe the process of behavior change.
Step-by-step explanation:
The Transtheoretical Model (TTM) and The Precaution Adoption Process Model (PAPM) are both stage models for behavior change. The TTM proposes that individuals progress through five stages of change: precontemplation, contemplation, preparation, action, and maintenance. The PAPM similarly suggests that individuals move through five stages: unawareness, unengaged, decided, decided not to act, and acting. Both models recognize that behavior change is a process that occurs over time and that individuals may be at different stages at any given time.
