Purpose: To explore whether reducing substance misuse through a brief motivational intervention also reduces aggression and HIV risk behaviours.Methods: Participants were enrolled in a randomized controlled trial in primary care if they screened positive for substance misuse. Substance misuse was assessed using the Alcohol, Smoking and Substance Involvement Screening Test; aggression, using a modified version of the Explicit Aggression Scale; and HIV risk, through a count of common risk behaviours. The intervention was received on the day of the baseline interview, with a 3-month follow-up.Results: Participants who received the intervention were significantly more likely to reduce their alcohol use than those who did not; no effect was identified for other substances. In addition, participants who reduced substance misuse (whether as an effect of the intervention or not) also reduced aggression but not HIV risk behaviours.Conclusions: Reducing substance misuse through any means reduces aggression; other interventions are needed for HIV risk reduction.
