A group of brief, selective, personality-targeted interventions aimed at reducing substance (alcohol and drugs) use and misuse.

The intervention initially identifies secondary school students at high risk of substance misuse based on self-reported questionnaires which assess their personality profiles. In most cases a student is deemed to be at high risk of substance misuse if their score in one of the categories: hopelessness, sensation seeking, sensitivity or impulsivity, is more than one standard deviation above the mean score in their school.
