Reasons for binge drinking among undergraduate students: An application of behavioural reasoning theory

This study sought to apply behavioural reasoning theory (BRT) to the prediction of undergraduate students' binge drinking intentions and behaviour. The reasons students use to justify and defend binge drinking may provide important information on motivations underlying such behaviour.

Undergraduate students (N= 265) completed questionnaires assessing their reasons for and against binge drinking, attitude, subjective norm, perceived behavioural control, intention, and past behaviour. Frequency of binge drinking was assessed at 1-week follow-up (N= 172).

A series of path analyses were conducted to assess the direct and indirect effects of the BRT variables on binge drinking intentions and behaviour. The variables under consideration accounted for 80% of the variance in binge drinking intentions (with past behaviour, reasons for binge drinking, and attitude having significant direct effects on intention), and 34% of the variance in binge drinking at 1-week follow-up (with past behaviour, perceived behavioural control, and intention having significant direct effects on future behaviour). Additional regression analyses revealed that respondents who strongly endorsed being sociable and having fun as reasons for binge drinking were more likely to intend to engage in binge drinking over the subsequent week.

The results provide support for BRT as a framework for understanding undergraduate students' binge drinking intentions and behaviour, and suggest that interventions need to focus on the social reasons for engaging in binge drinking in undergraduate students.
