The Drug Treatment Outcomes Research Study (DTORS): Final outcomes report

Abstract

i Summary Most improvements occur within the first few months of entering treatment. The changes in behaviour observed at first follow-up (three to five months after initial interview) are mainly only sustained at second follow-up (11 to13 months), although there are some additional improvements during this later stage of treatment. This may suggest that there are opportunities to further capitalise on the early gains that are achieved. Further work is needed to establish whether these gains are sustained once treatment has stopped. Levels of drug use declined rapidly within the first three months of starting treatment, and then continued at the same rate, for up to six months. These findings support the validity of the national performance indicator of retention in treatment for at least three months, but suggest potential value in longer measures of retention than currently employed as well as the need for treatment facilities to focus on a continuing process of change.
