New research published today by the Economic and Social Research Council shows that positive, informative strategies which help people set specific health and environmental goals are far more effective when it comes to encouraging behaviour change than negatives strategies which employ messages of fear, guilt or regret.
Recent years have seen increasing efforts to encourage people to do more for their health and for the environment, for example by recycling more, using cars less and taking more exercise. But what messages have been successful, and why?
Theories have long suggested that by changing attitude, social rules and peoples own ability to reach their goals, people's intentions or decisions to act in a particular fashion will be changed, which in turn determines the extent of change in behaviour. But the supporting evidence for these widely accepted ideas was weak; there was a need to take a closer look at experiments that changed attitudes, norms and self-efficacy in order to measure the true extent of any changes in subsequent intentions and behaviour.
The research project, 'Does changing attitudes, norms or self-efficacy change intentions and behaviour?', led by Professor Paschal Sheeran of Sheffield University, provides the crucial missing evidence about the role of these three factors in behaviour change by reviewing all the successful experiments in the past 25 years and quantifying their effects on decisions and actions.
The team identified 33 distinct strategies for changing intentions and behaviour across the 129 different studies. The most frequently used strategies provided general information, details of consequences and opportunities for comparison. Yet the most effective strategies were to prompt practice, set specific goals, generate self-talk, agree a behavioural contract and prompt review of behavioural goals. The two least effective strategies involved arousing fear and causing people to regret if
