The objective of the study was to identify psychosocial factors and salient beliefs associated with the intention of young people to not binge drink in the next month, applying an extended version of the theory of planned behavior.
Among 200 youths randomly recruited from adult education centers in the province of Quebec, Canada, 150 completed a questionnaire. Of these, 141 youths reported having used alcohol in the last year—analyses were performed on this sub-sample.
The prediction model demonstrated that perceived behavioral control (odds ratio, OR = 2.60, 95% confidence interval, CI 1.59–4.23; P = 0.0001), attitude (OR = 2.49, 95% CI 1.14–5.43; P = 0.02) and moral norm (OR = 1.88, 95% CI 1.23–2.88; P = 0.004) are three determinant variables of intention to not binge drink in the next month. The intention is also related to cannabis use in the last month (OR = 0.17 95% CI 0.05–0.53; P = 0.002). Young people who believe that if they do not binge drink in the next month, they will have a lower risk of getting depressed (OR = 1.53, 95% CI 1.23–1.90; P = 0.0001), and those who believe they will be able to not binge drink even if they are at a party (OR = 1.58, 95% CI 1.29–1.94; P < 0.0001), are more likely to have a positive intention.
Despite some methodological limitations, this study revealed several options for helping young people to not binge drink during their school career.
