What is the COM-B model?
The COM-B model is a theoretical framework used in behavioral science to understand and analyze behavior. The name “COM-B” stands for Capability, Opportunity, Motivation, and Behavior, representing the essential conditions required for a voluntary behavior to occur.
How does COM-B model work?
The COM-B model operates as a behavior model within the framework of Behavioral Design to analyze and influence behavior. It integrates three essential components: Capability, Opportunity, and Motivation. These elements interact to lead to the execution of a specific Behavior.
This relates to both physical and psychological abilities that enable an individual to perform the behavior, such as having the necessary skills and knowledge.
This includes external factors that make the behavior possible or prompt it, considering environmental context and social influences.
This involves all brain processes, reflective and automatic, that energize and direct behavior, like intentions, beliefs, emotions, and habits.
COM-B model examples
The COM-B model can be applied to various contexts to design interventions that influence behavior change. Here are some examples:
Designing interventions to promote healthy eating by enhancing knowledge (Capability), creating supportive environments (Opportunity), and encouraging positive attitudes (Motivation).
Implementing strategies to improve student engagement by improving teaching methods (Capability), facilitating collaborative learning (Opportunity), and nurturing intrinsic motivation (Motivation).
What are the benefits of COM-B?
The COM-B model offers a comprehensive and versatile framework for understanding and changing behavior. Its benefits include:
It provides a systematic way to analyze behaviors and understand the factors influencing them.
Helps in designing effective interventions tailored to specific behaviors.
Its flexibility allows application across various fields and contexts, making it a valuable tool in behavioral science.
What are the three layers of behavioral change?
In the context of the COM-B model and behavioral change, three layers represent the interconnected aspects of the model, the intervention functions, and the policy categories. These layers provide a holistic approach to understanding and implementing behavioral change:
The innermost layer representing Capability, Opportunity, and Motivation, which directly influences Behavior.
The middle layer that outlines strategies to address the components of the COM-B model.
The outermost layer that identifies high-level policy and environmental strategies to support the intervention functions.
