Study Notes

  • The COM-B model is a model for behavioural change that was developed from the Theoretical Domains Framework (TDF), which encompasses the domains of several other behavioural models.
  • The COM-B model states that an individual must have adequate Capability, Opportunity, and Motivation for a Behaviour (such as medicine-taking) to take place and if there are deficits in any one of these areas, the behaviour may not occur.
  • Factors such as issues with memory, dexterity and ability to plan relate to ‘capability’, factors such as perceptions and beliefs, as well as emotions and habitual processes, relate to ‘motivation’ and factors such as social support and regimen complexity relate to ‘Opportunity’.
  • The most influential factor in the COM-B model is the motivational aspect.
  • To facilitate this, there may be a role for some education and a degree of additional support for patients.
  • It is important to explore the patient’s concerns and values to help identify any motivational, belief or other barriers to taking medication as advised.
  • The COM-B model can help to provide some insights as to why some patients do not take their medicines as they are intended to be used.
  • Interventions can then be personalised to the needs of that individual.
