The COM-B System of Behaviour Change: Properties, Problems and Prospects

The COM-B system of behaviour change is analysed. The system involves three processes termed "Capability", "Opportunity" and "Motivation". The crucial motivational element of "Wanting" is missing from the system. Wanting eliminates the intention-behaviour gap in explaining why people do or do not do the things necessary for their survival. Prospects for self-protective behaviour change in health emergencies such as the SARS-COV-2 pandemic will be greatly improved when the core motivational process of wanting is restored within motivational theory.
