Despite the emphasis on providing high quality mental health and addiction treatment, there has been relatively little consideration given to examining clients' perceptions of addiction treatment (consumer satisfaction) as a quality improvement strategy. The present article reports on a survey of a representative sample of 93 clients receiving opioid substitution treatment (OST). Employed participants reported higher treatment satisfaction and a pattern of positive associations was found between satisfaction and general health, mental health, social functioning, lower methadone doses, and participants' ratings of their treatment progress. Lower satisfaction was associated with higher frequency of benzodiazepine use, and, for women, longer treatment duration. Maori participants rated their treatment progress as lower than that of non-Maori. Results strongly endorse recording participants' comments to provide a deeper understanding of survey item ratings. The study findings highlight the need for a research focus on the roles of mental health and other registered nurses who work with people receiving OST in specialist service and primary care settings, and endorse a partnership approach to future research in this area. The pattern of findings arising from this study suggests key strategies for improving the flexibility and client responsiveness of OST.
