Preventable unhealthy behaviours contribute strongly to socioeconomic inequalities in health and mortality (Pampel, Krueger & Denney, 2010). To reduce health inequalities, it is therefore important to understand what drives these behavioural differences. Behavioural ecological theory suggests that health behaviour should be influenced by the perceived controllability of overall mortality risk. Further, small initial socioeconomic disparities in exposure to uncontrollable mortality risks may drive differences in unhealthy behaviour, leading to larger eventual health inequalities (Pepper & Nettle, 2014a; 2017). Empirical and experimental studies have found support for this theory: The association between socioeconomic status and health effort has been found to be mediated by perceived control over mortality risk (Pepper & Nettle 2014b). Further, experiments have demonstrated that priming controllable mortality risk increases participants’ tendencies to choose a healthier food option (Pepper & Nettle 2014c).
This PhD project will extend this work by establishing; a) what types of health and mortality risk are widely perceived to be uncontrollable, b) whether there are socioeconomic differences in perceptions about control over these risks, c) the sources of information which people use to assess their personal risk and, d) whether personal risk perceptions are accurate. This new information will then be used to guide pilot work, testing the effect of perceived-control-enhancing messages on health behaviour.
The research will be valuable because it will generate novel information about the aetiology and nature of health risk perception. Further, it will test the feasibility of the concept of health interventions to enhance perceived control over mortality risk. Finally, it will suggest whether improving safety in deprived neighbourhoods could drive improved health behaviours, reducing total health inequalities.
