Revise Strategies for promoting health for Cambridge 9990 (3.5.1)

Health education programmes aim to promote positive health behaviours by providing information and developing skills in specific settings. In schools, this can be integrated into the curriculum, such as through Personal, Social, Health and Economic (PSHE) education, or via specific campaigns like Tapper et al.'s (2003) 'Food Dudes' programme, which successfully increased fruit and vegetable consumption in primary school children using role modelling and rewards. In worksites, strategies range from posters and leaflets to comprehensive wellness programmes addressing stress, smoking, and fitness. For example, Gomel et al. (1993) found that worksite interventions combining risk assessment with behavioural counselling were effective in reducing risk factors for cardiovascular disease. The primary advantage of these settings is access to a large, captive audience for prolonged periods.

Fear appeals are persuasive messages that attempt to change behaviour by highlighting the negative consequences of a particular action or inaction. The underlying theory is that inducing fear will motivate individuals to act to reduce the threat. However, the relationship is not straightforward. The classic study by Janis and Feshbach (1953) on dental hygiene found that a low-fear message was more effective in promoting behaviour change than medium or high-fear messages, which could cause defensive avoidance. This supports an inverted-U hypothesis, where moderate fear is optimal. Later research, such as by Leventhal, suggests high-fear appeals can be effective, but only if they are coupled with clear instructions on how to perform the desired behaviour and information that boosts self-efficacy (the belief that one can succeed).

The Health Belief Model (HBM), developed by Rosenstock in the 1950s, is a cognitive model that predicts health behaviours by focusing on individual attitudes and beliefs. It proposes that a person's readiness to act is influenced by six key factors: perceived susceptibility (one's risk of getting a condition), perceived severity (how serious the condition is), perceived benefits (the effectiveness of the action to reduce the threat), perceived barriers (the costs or obstacles of the action), cues to action (triggers to prompt the behaviour), and self-efficacy (confidence in one's ability to act). For example, a person is more likely to get a flu jab if they believe they are susceptible to flu, that flu is a serious illness, that the jab is effective, and that barriers like cost or inconvenience are low.

Developed by Prochaska and DiClemente (1983), the Stages of Change Model (SCM) views behaviour change not as a single event, but as a dynamic process that occurs over time through a series of five stages. These are: 1) Precontemplation (no intention to change), 2) Contemplation (aware a problem exists, thinking about changing), 3) Preparation (intending to take action soon), 4) Action (making modifications to behaviour), and 5) Maintenance (working to prevent relapse). A key feature of the model is its cyclical nature; individuals can move back and forth between stages, and relapse is considered a normal part of the process, leading back to an earlier stage rather than complete failure. This model is useful for tailoring interventions to an individual's specific stage of readiness.
