Understanding binge drinking among young people: an application of the Theory of Planned Behaviour.

Binge drinking (i.e. consuming half the recommended weekly consumption of alcohol in a single session) is a common activity among young people. Using the Theory of Planned Behaviour as its theoretical framework, this paper reports a study exploring the motivational and attitudinal factors underlying binge drinking in a sample of undergraduate students. Questionnaires were completed by 136 undergraduates which focused on their drinking behaviour and their beliefs about binge drinking. Binge drinking was found to be more prevalent among male respondents, and a number of significant differences in the beliefs of male and female respondents were found which supported this difference in drinking behaviour. A regression analysis identified two key predictors of the frequency of binge drinking; these being positive control beliefs and perceived behavioural control. Frequent binge drinkers were more likely to recognize the influence of a range of factors which may serve to encourage binge drinking (e.g. celebrating an event) and less likely to believe that the decision to engage in binge drinking is under their control. The results are discussed in relation to measures which may help to reduce the incidence of binge drinking through changes in the social environment.
