6. Behavioural change wheel Flashcards
what are the 3 parts/components of behavioural change wheel?
- sources of behaviour (COM-B)
- intervention functions
- policy categories (won’t talk about)
what are the main constructs + subcomponents of the COM-B? + define
CAPABILITY
- physical: physical capacity to do the behaviour (strength, skills, balance, dexterity)
- psychological: person’s mental functioning (understanding, memory, knowledge to engage in behaviour)
MOTIVATION
- reflective: conscious thought processes (plans) –>
*includes cognitive attitudes, OE, decision balance, SE, psychological needs, intentions, motivational regulations
- automatic: habits, instincts, affect/emotions, impulses
OPPORTUNITY
- physical: aspects of physical environment (space (accessible, weather), time, money, materials)
- social: aspects that involve others including culture, social norms, people around you
need all 3 in order to lead to behaviour!! if one is low, then you won’t get the behaviour
what are the 3 pros and 3 cons of COM-B behaviour change wheeel?
PRO:
- simple, easy to understand
- comprehensive (based on summary of theoretical constructs)
- components are evidence-based (summary of evidence)
CONS:
- too simple?
- are nuances of motivation important? ie quality of motivation –> self-efficacy, self-determined motivation –> all in reflective motivation
- evidence of predictive abiliity to model is still emerging –> bc very new theory –> lacking real-life evidence
what are the 9 intervention functions of the behaviour change wheel?
- EDUCATION: increasing knowledge or understanding
- PERSUASION: using communication to induce positive or negative feelings or stimulate action (ie using imagery to motivate increases in PA)
- INCENTIVISATION: creating expectation of reward (ie money)
- COERCION: creating expectation of punishment or cost (ie increasing cost)
- TRAINING: imparting skills (ie provide training)
- RESTRICTION: using rules to reduce the opportunity to engage in the target behaviour (or to increase the target behaviour by reducing the opportunity to engage in competing behaviours) –> ie prohibiting sales of solvents for ppl under 18 to reduce use for intoxication
- ENVIRONMENTAL RESTRUCTURING: changing physical and social context (ie providing on screen prompts for GPs to ask about smoking behaviour)
- MODELING: providing an example for people to aspire to or imitate (ie TV drama scenes practicing safe-sex)
- ENABLEMENT: increasing means/reducing barriers to increase capability or opportunity
which main construct (and which subcomponent) do these interventions target?
- EDUCATION:
- PERSUASION
- INCENTIVISATION
- COERCION
- TRAINING
- EDUCATION: Capability (psychological) + motivation (reflective)
- PERSUASION: Motivation (reflective and automatic)
- INCENTIVISATION: Motivation (reflective and automatic)
- COERCION: Motivation (reflective and automatic)
- TRAINING: capability (physical and psychological)
which main construct (and which subcomponent) do these interventions target?
- RESTRICTION
- ENVIRONMENTAL RESTRUCTURING
- MODELING
- ENABLEMENT
- RESTRICTION: opportunity (physical and social)
- ENVIRONMENTAL RESTRUCTURING: motivation (automatic) + opportunity (physical and social)
- MODELING: motivation (automatic) + capability ish (psychological) and motivation ish (reflective, from vicarious experience increasing SE)
- ENABLEMENT: capability (physical and psychological) + motivation (automatic) + opportunity (physical and social)
is there a lot of research on behaviour change wheel? explain
- relatively new theory!
- lots of research/papers on how to develop interventions
- still waiting on studies that actually tested the interventions
what does research on COM-B show? which 3 subcomponents have (positive or negative) relationship with PA?
- research in UK during COVID-19
a) physical capability –> -0.09 –> increase physical cap = decrease PA –> might have less opportunity or less will to do it bc already know they can do it
b) physical opportunity –> 0.18 –> positive rel
c) reflective motivation –> 0.22 –> positive relationship
*low relationship for more social and psychological aspects (psychological capability, social opportunity, automatic motivation) –> maybe need more psychological and social interventions
what was good about this paper: “the use of behaviour change wheel in the development of participACTION’s physical activity app”?
they actually linked the COM-B concept, with a subtheme, with the intervention function, with behaviour change techniques, with examples!!
*good example for intervention project
BCW summary:
- old or new theory?
- 2 pros
- 1 limitation
- trending new theory!
1) evidence-based summary of key behaviour change principles –> provides credibility!
2) provides guidance in developing interventions! = very attractive
1) not many empirical tests/evidence bc new theory
