The CAP Study: Evaluating a comprehensive universal and targeted intervention designed to prevent substance use and related harms in Australian adolescents.

Dataset includes a total of 2190 students (mean age, 13.3 years. 57.% male) from 26 Australian high schools. Participants were followed up at 6 months, 1 year, 2 years, 3 years, 5.5 years, and 7 years. Schools were randomly assigned to deliver the following: (1) universal Web-based prevention for all students (Climate Schools); (2) selective prevention for high-risk students (Preventure); (3) combined universal and selective prevention (Climate Schools and Preventure [CAP]); or (4) health education as usual (control). Primary outcomes were self-reported frequency of alcohol consumption and binge drinking, alcohol-related harms, and hazardous alcohol use, at the 7-year follow-up.
