title: The impact of a treatment process for substance users as a function of their degree of exposure to treatment.
abstract: The objective of this research is to evaluate the outcomes of a treatment for addicts. 248 subjects were tested before and 5 months after treatment with the Addiction Severity Index (ASI). Exposure to treatment was based on the number of clients' contact hours with a therapist. The sample was divided into three groups according to number of hours spent in treatment. The data were analyzed using MANOVA on the seven scales of the ASI for the three groups and the two time periods. Results showed that the severity of addiction problems decreased after treatment, and decreased more for subjects who underwent treatment for a longer period of time.
