ENGLISH:
Aim: We tested the efficacy of a brief intervention based on motivational interviewing (MI) to reduce high-risk injection behaviours over a 6-month period among people who inject drugs (PWID). Design: A single-site two-group parallel randomized controlled trial comparing MI with a brief educational intervention (EI). Setting: A study office located in downtown Montréal, Canada, close to the community-based harm reduction programmes where PWID were recruited. Participants: PWID who had shared drug injection equipment or shared drugs by backloading or frontloading in the month prior to recruitment were randomized to either the MI (112) or EI (109) groups. Intervention: The MI aimed to (1) encourage PWID to voice their desires, needs and reasons to change behaviours; (2) boost motivation to change behaviours; and (3) when the person was ready, support the plan he or she chose to reduce injection risk behaviours. The EI consisted of an individual session about safe injection behaviours. Measurements: The primary outcome was defined as having any of these risk behaviours at 6?months: having shared syringes, containers, filters or water to inject drugs in the previous month and backloading/frontloading; each behaviour was examined separately, as secondary outcomes. Findings: The probability of reporting a risk injection behaviour decreased in both the MI and the EI groups. At 6-month follow-up, participants who reported any risk behaviours were 50% [odds ratio (OR) = 0.50; confidence interval (CI) = 0.13-0.87] less likely to be in the MI group than in the EI group as well as those who reported sharing containers (OR = 0.50; CI = 0.09-0.90). PWID who reported sharing equipment excluding syringes were 53% less likely to be in the MI group (OR = 0.47; CI = 0.11-0.84). Conclusions: A brief motivational interviewing intervention was more effective than a brief educational intervention in reducing some high risk injecting behaviours up in the subsequent 6 months. FRANÇAIS : Une équipe de chercheurs canadiens a mis en évidence l'impact positif, dans le temps, d'une intervention brève motivationnelle (IBM) sur les pratiques d'injection à haut-risque, dans le cadre d'une étude randomisée contrôlée. L'IBM y était comparée à une intervention de type éducationnel ("educational intervention") (IE) basée exclusivement sur la délivrance d'informations sur les risques associés à l'injection et les moyens existants pour limiter ces risques. Les participants répartis en deux groupes bénéficiaient de l'un ou l'autre mode d'intervention (IBM : 112 - IE : 109). Or si l'IE et l'IBM étaient associées, dans les deux groupes, à une plus faible probabilité de comportements à risque liés à l'injection comme le partage des seringues et du petit matériel, à 6 mois, les effets de l'IBM apparaissaient comme plus durables, limitant davantage les comportements à risque au-delà de 6 mois.
