Based on their scores on the Substance Use Risk Profile Scale, at-risk students will be identified and invited to participate in the Preventure program in the first year of the trial. Parents of grade 7 students reporting discord at home on the Alabama parenting questionnaire will be invited to participate to the parent program. Participating students with clinically significant internalizing and externalizing problems will be invited to receive Inter-Action services. Internalizing and externalizing problems will be assessed using self-report measures such as the Patient Health Questionnaire for Adolescents, the Strengths and Difficulties Questionnaire, the screening tool for the detection of alcohol and drug problems in adolescents (DEP-ADO) and the development and well-being assessment (DAWBA).
