The National Treatment Outcome Research Study (NTORS): 4–5 year follow‐up results

Abstract

Substantial reductions across a range of problem behaviours were found 4-5 years after patients were admitted to national treatment programmes delivered under day-to-day conditions. The less satisfactory outcomes for heavy drinking and use of crack cocaine suggest the need for services to be modified to tackle these problems more effectively. Despite differences between the United Kingdom and the United States in patient populations and in treatment programmes, there are many similarities between the two countries in outcomes from large-scale, multi-site studies.
