Peer-Group and Price Influence Students Drinking Along with Planned BehaviourAlcohol and Alcoholism Advance Access published online on April 29, 2008
To examine the theory of planned behaviour (TPB), as a
framework for explaining binge drinking among young adults.
Drinking alcohol was common; 39.6% of males
and 35.9% of females reported binge drinking. The TPB explained
7% of the variance in intention to drink. Overall, 43% of the
variance in intention, 83% of the variance in total weekly consumption
and 44% of the variance in binge drinking was explained. The
frequency of drinking and the drinking behaviour of friends
significantly predicted intention to drink and binge drinking,
respectively. Binge drinkers were influenced by peers and social-situational
factors. Pressure to drink was greater for males; undergraduates
were influenced by the size of the drinking group, ‘special
offer’ prices, and the availability of alcohol.
The TPB appeared to be a weak predictor of student drinking
but this may be a result of how constructs were measured. With
friends’ drinking behaviour emerging as a significant
predictor of alcohol consumption, interventions seeking to reduce
excessive drinking should target the role of peers and the university
environment in which drinking occurs.
