Study Notes
Models of Health Behaviour
- Models are used to predict whether people will change their health behaviour and to design interventions to change it.
- The Health Belief Model (HBM) predicts health behaviour based on threat perception, behavioural evaluation, cues to action, health motivation, and perceived control.
- The HBM can predict a wide range of health behaviours, but it assumes rational decision-making and doesn't account for emotional factors or external factors like the environment or socio-economic status.
- The Theory of Reasoned Action/Planned Behaviour (TRA/TPB) is a social cognition model that considers people as active information processors, taking into account attitudes, normative beliefs, and their social world.
- The TPB extends the TRA by adding perceived behavioural control, which includes internal and external control factors.
- The TRA/TPB can predict a range of health behaviours, but it also assumes rational decision-making and doesn't account for habits or irrational behaviour.
- Interventions to change health behaviours are often based on models like the HBM or TPB, using information-based approaches to increase awareness of the benefits and costs of behaviour change and equip people with skills and resources.
- Sutton (2010) developed a series of steps for developing interventions based on the TPB, including identifying the target behaviour and population, identifying the most salient beliefs and predictors of behavioural intention, and developing interventions to change these beliefs.
- The beliefs people have about health/illness and health behaviours, together with other factors, influence whether people change their health behaviours.
- The HBM and TPB are two models used to predict and design interventions for health behaviour change.
- The HBM focuses on threat perception, behavioural evaluation, cues to action, health motivation, and perceived control.
- The TPB extends the TRA by adding perceived behavioural control and considers people as active information processors taking into account attitudes, normative beliefs, and their social world.
