This study tested a school-based program called Preventure in 3,900 Canadian teens. The program targets four personality traits linked to substance misuse, aiming to delay or prevent alcohol and drug use. Researchers also measured whether delaying substance use helps protect cognitive development during adolescence.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Public or private high school * Must have a Grade 7 cohort of at least 100 youth (up to 200), providing access to 45-90 high risk students per school Selection of high risk youth: Inclusion criteria for students are that they be enrolled in Grade 7 and that they have provided active assent and passive parental consent to participate in the longitudinal survey and randomised trial phases of this study. Participants who score 1 standard deviation above the school mean on one of four subscales of the Substance Use Risk Profile Scale will be selected to participate in the intervention groups, but all students will be followed on outcomes. There are no other exclusion criteria for participants. Exclusion Criteria: * Schools cannot be classified as having a majority of their students coded as special needs students, because these schools are smaller and the intervention protocol would have to be tailored for their particular needs
