School-based multiple risk behaviour interventions to prevent illicit drug use
Summary of the evidence
A recent systematic review (MacArthur et al 2018) of 70 RCTs addressing two or more risk behaviours (with a follow-up period of at least six months) and targetting children up to 18 years of age, found that:
- universal school-based multiple risk behaviour interventions may be effective in preventing illicit drug use (OR 0.74, 95% CI 0.55 to 1.00; n=5 studies; 11,058 participants; low-quality evidence) at up to 12 months' follow-up
