Summary
The episode works through four thorny issues from the lesson on individual health behaviour theories. It separates perceived barriers, cues to action, self-efficacy and perceived behavioural control through a made-up case of colon screening in British Columbia, and it uses experimental and meta-analytic evidence to examine whether changing a belief or an intention changes behaviour. A harder worked example combines the Precaution Adoption Process Model with the Health Belief Model and the Theory of Planned Behavior to plan extreme heat preparedness for older adults living alone, drawing on the findings from the 2021 heat dome. The hosts close by debating whether the stages of change are real, and they agree that a person's stage should guide the message while help is offered to everyone.
