Does successful school-based prevention of bullying influence substance use among 13- to 16-year-olds?

摘要

Aim: To test whether the school-based Olweus prevention programme against bullying may have lasting effects on substance use, a hypothesis based on the characteristics of bullies having misconduct behaviour associated with substance use. Methods: The Olweus programme was introduced from grades 7 through 9 in four schools and monitored up to grade 10 in Oslo in 2001/02, with two schools serving as controls. Students responded to annual questionnaires about substance use. Three-level analyses were applied to check for increases in substance use over time. Findings: There was no significant difference in the frequency of alcohol use between the experimental schools and the control schools. Alcohol intoxication and cannabis use, and possibly smoking, were higher in the control schools than in the experiment schools.
