L8: Health Behaviour II Flashcards
Which theory best describes health behaviours?
Integrated approach
Hard to determine which one is the best as they have all have pros and cons
Impact of intervention depends on type of behaviour, population being targeted and the context
Why don’t people behave in ways that promote health?
Lack capability (inadequate knowledge and/or skills)
Insufficient opportunities
Motivation to engage in healthy behaviour is lacking
→ healthy behaviours are usually unpleasant, difficult, boring and unhealthy behaviours are usually enjoyable or meet immediate needs
What is meant by the COM-B model of behaviour?
Capability
Opportunity
Motivation
to change behaviour or engage in a behaviour
What is meant by capability?
Physical and psychological capability: knowledge, skills, strength and stamina
(If they don’t know how to do it or lack the skills to be able to do it then its impossible to do!)
What is meant by opportunity?
Physical and social opportunity: time, resources, cues/prompts
(need to have the resource to be able to make the change and become healthier)
What is meant by motivation?
Reflective and automatic motivation: plans, evaluations, desires and impulses
(got to have the want or the encouragement to be able to stick at it if though its hard)
What it nudge theory?
Idea that people respond to cues in the environment that unconsciously shape their choices - choice architecture
80% human behaviour is automatic
In what ways can nudge theory help with health behaviour?
Can influence people to make healthier food choices e.g. placing the fruit bowl on the front counter so that people buy more fruit
e.g. smaller plates
What is required to make nudge sucessful?
Must decrease the effort required to make the desired choice
Improve motivation to opt for that choice
Can nudge be used on its own?
Weak on its own
Should be done alongside other interventions
