To investigate the utility of an extended Theory of Planned Behaviour (TPB), including descriptive norms and anticipated regret, in predicting binge-drinking intentions and behaviour.Methods
A total of 178 undergraduates completed a questionnaire containing measures of TPB variables, descriptive norms, anticipated regret, and previous binge-drinking behaviour. One week later, 104 students completed a measure of binge-drinking behaviour.Results
Hierarchical regression demonstrated that attitudes (beta=0.30, P < 0.001) and anticipated regret (beta=0.47, P < 0.001) were significant predictors of intentions, with the final equation accounting for 58% of the variance. Hierarchial regression found that intentions (beta=−0.21, P < 0.05) and previous binge-drinking behaviour (beta=0.36, P < 0.01) predicted current drinking behaviour, accounting for 33% of the variance.Conclusions
The study suggests that modifying attitudes and inducing regret may be effective strategies for reducing binge-drinking intentions among undergraduates, which should reduce subsequent binge-drinking behaviour.
