Behavior Change Models (COM‑B, TTM)
Behavior Change Models, such as COM-B (Capability, Opportunity, Motivation-Behavior) and TTM (Transtheoretical Model), provide frameworks for understanding and influencing how people alter their actions. COM-B focuses on the interplay between an individual's capability, opportunity, and motivation in driving behavior. TTM outlines stages of change—precontemplation, contemplation, preparation, action, and maintenance—highlighting the process individuals undergo when modifying behaviors, thus aiding in designing effective interventions.

❓ Frequently Asked Questions
What is the COM-B model and its components?
COM-B is a behavior framework where behavior arises from Capability, Opportunity, and Motivation. Capability covers knowledge and skills; Opportunity includes external context and social support; Motivation comprises reflective and automatic drives to act.
What does Capability mean in COM-B?
Capability means having the skills, knowledge, and physical or mental capacity to perform the behavior.
What is the Transtheoretical Model (TTM) and its stages of change?
TTM describes progress through stages—Precontemplation, Contemplation, Preparation, Action, and Maintenance—as people change their behavior, guided by processes of change and self-efficacy.
How can COM-B and TTM be used together in health interventions?
Use TTM to assess a person’s stage of change and tailor interventions that modify COM-B components to move them to the next stage (e.g., build capability, remove barriers, boost motivation).
