Does making people think they are at risk, or making them feel afraid or worried, change their behaviour? Analysing the experimental evidence
No full textCommon sense and scientific research share the assumption that risk appraisals - such as perceptions of risk or fear - are key determinants of people's actions. Consequently, to ensure people recycle more, drive less, or maintain a healthy weight (for instance), it is assumed that they should first recognise that global warming or obesity are serious threats that place them at personal risk. Although the idea that risk appraisals have an important impact on behaviour is plausible, the evidence supporting it is weak, because most studies only compute correlations between appraisals and behaviour. Thus, we cannot say for certain that making people think they are at risk or feel afraid leads them to change their behaviour.
The researchers will conduct a quantitative review of intervention studies that have successfully changed key risk appraisal variables to determine
how often these changes alter intentions and behaviour;
how big an effect these changes have;
whether other variables, such as people's beliefs about their ability to change behaviour, affect the process.
This will permit firmer conclusions to be drawn about how effective it is to try to change behaviour by making people think and feel that they are at risk
Understanding and using self-generated validity to promote behaviour change
No full textSelf-generated validity (SGV) describes the finding that asking participants to report their intention to perform a behaviour (eg, "Do you intend to donate blood?") causes greater subsequent performance of that behaviour compared to not asking about intentions.
Our recent research has shown that SGV can be used to increase two objectively assessed health behaviours (blood donation; screening attendance) over periods of up to 12 months. We aim to further our understanding of SGV and assess how it can be used to promote behaviour change. We will explore the generality of SGV (across approach and avoidance behaviours; and across different cognition measures), the mechanisms of effect (role of degree of deliberation about the behaviour and public commitment to the behaviour), and the moderators of the effect (impact of measuring different cognitions, impact of different levels of past experience with the behaviour).
Real world Randomised Controlled Trials on two behaviours (cervical screening, child immunisation) will examine what factors influence SGV. In addition, Laboratory Experiments will further elucidate the generality, mechanisms and moderators of SGV. Better understanding of SGV would inform its use as a simple but effective way to change behaviour and inform our understanding of how merely measuring cognitions may change behaviour

State-of-the-Art Synthesis of Interventions to Promote Quit Intentions and Smoking Cessation
No full textThis project will synthesize findings from randomized controlled trials to discover how effective are interventions in promoting quit intentions and transforming quit intentions into smoking cessation. Our findings will shape future research and practice by ascertaining ‘what works’ in smoking cessation trials and by making research-tested, effective program materials accessible via the project website (www.SmokingCessationTrials.info)
