Methods A school-based randomised controlled prevention trial was conducted over a period of 33 months (n = 1,874 6th-graders at baseline, mean age 11.82). We employed a two-level random intercept logistic model for panel data to predict the probabilities of cannabis use for each student. The prediction is based on eight risk/protective factors and on whether a student is included in the control or intervention group. Having divided the sample into a low-risk group (1/4 of students), a moderate-risk group, and a high-risk group (1/4 of students), we calculated the effect of the intervention and described the risk and protective factors for each of the groups.Results All children profited from the intervention. The average predicted probabilities of cannabis use for the students in the control and intervention groups were 6.53% and 4.3% for the low-risk group, 15.34% and 10.91% for the moderate-risk group, and 32.61% and 25.51% for the high-risk group, respectively. The probability of cannabis use was related to all eight of the risk/protective factors. School grades, thoughts of hurting oneself, and breaking the rules are the three most important factors distinguishing between high-risk and low-risk children. Conclusions Selective/indicated prevention efforts are encouraged in children with high-risk profiles, as our universal prevention programme does not produce sufficient improvement in this group. The questionnaire items used are strong predictors of cannabis use in adolescents aged 12-15 years.
