Step 1: Overview of the COM B Model.
The COM-B model can be used to categorise barriers into three groups.
1. Capabilities - refer to a person's physical or psychological ability to perform the behaviour.
2. Opportunities - refer to anything in the physical or social environment that may encourage or discourage a behaviour.
3. Motivations - refer to internal reflective and automatic mechanisms that activate or inhibit a behaviour.
