COM-B Model
‘The COM-B model is a general model for predicting behaviour and developing interventions to influence it. This website is your hub for information about the model and how to use it to analyse and develop behaviour change interventions. Use the contact us link to provide comments on the model or this website and let us know about things you’d like us to add.’

COM-B and Ontologies
The COM-B Model links to the Mechanism of Actions (MoA) Ontology within the Behaviour Change Intervention Ontology (BCIO). Some COM-B constructs correspond directly with some BCIO constructs, while others link with MoA constructs using relations such as ‘causally influences’.
Ontologies are standardised frameworks for representing constructs including influences on behaviour. Ontologies are increasingly being used in biological, behavioural and social sciences. When referring to COM-B it can be helpful to refer to COM-B constructs using their ontology equivalents.
Using the COM-B Model with the Behaviour Change Wheel
The COM-B model lies at the heart of the Behaviour Change Wheel (BCW) framework for analysing or developing interventions. (See BCW book or brief guides.)
Use the resources and tools in this website to gain insights into these applications.
