Aims

Design and Method

The study utilised data collected for the NSW component of the Australian Treatment Outcome Study (ATOS). Five hundred and thirty five heroin users were recruited on entry to treatment through methadone/buprenorphine maintenance, detoxification and residential rehabilitation services. An additional 80 heroin users not currently in treatment were also recruited. Using a structured questionnaire, participants were interviewed on entry to treatment for heroin dependence and again at 3, 12 and 24 months post treatment entry.
