In the COM-B framework, environmental context & resources belong to which dimension of behavior change?

• A. Capability
• B. Opportunity
• C. Motivation
• D. Health Literacy

Answer: (B)

The main idea here is how external factors shape what someone can do. In the COM-B model, behavior arises from Capability, Opportunity, and Motivation. Environmental context and resources are placed in Opportunity because they are external conditions that enable or constrain action. This includes physical opportunity like time, location, equipment, and money, as well as social opportunity such as norms and support from others. For example, having a nearby grocery store with affordable healthy options or a workplace that allows flexible lunch breaks creates the external conditions that make a behavior possible.

Capability covers a person’s actual ability, both physical and psychological, to perform the behavior. Motivation covers the internal drives and desires that energize and direct behavior. Health literacy isn’t one of the COM-B dimensions itself; it can influence capability or motivation indirectly, but it isn’t the labeled component here.
