Description
Summary:The present study compared methadone maintenance alone to methadone maintenance in combination with 16 weeks of either Intensive Twelve-Step Facilitation (ITSF) or Acceptance and Commitment Therapy (ACT) in a preliminary efficacy trial with polysubstance-abusing opiate addicts who were continuing to use drugs while on methadone maintenance. Results showed that the addition of ACT was associated with lower objectively assessed opiate and total drug use during follow-up than methadone maintenance alone, and lower subjective measures of total drug use at follow-up. An intent-to-treat analysis which assumed that missing drug data indicated drug use also provided support for the reliability of objectively assessed total drug use decreases in the ACT condition. ITSF reduced objective measures of total drug use during follow-up but not in the intent-to-treat analyses. Most measures of adjustment and psychological distress improved in all conditions, but there was no evidence of differential improvement across conditions in these areas. Both ACT and ITSF merit further exploration as a means of reducing severe drug abuse.
