The COM-B model is a framework for understanding and promoting behavior change. It was developed by researchers at the University of Cambridge, and is based on the idea that behavior is determined by three interrelated factors: capability, opportunity, and motivation. Capability refers to a person’s physical, psychological, and social ability to perform a behavior. Opportunity refers to the presence of enabling factors, such as time, resources, and support, that make it possible for a person to engage in the behavior. Motivation refers to the person’s intention or desire to perform the behavior. The COM-B model is a useful tool for understanding the factors that influence behavior, and for developing interventions to promote behavior change. It can be used in a variety of settings, including health promotion, education, and public policy.
