title: From heroin to methadone--social role changes and reinforcement differentials in relation to outcome on methadone. Part I. The study of reinforcement differentials.
abstract: This study examines the relevance of reinforcements available to the addict in five critical stages of his career to his success on methadone maintenance. In-depth focused interviews were held with 30 addicts who had completed a program of methadone induction and who were characterized by social worker's evaluations as Successful, Marginally Adjusted, or Failures. The Successful group showed a higher initial negative reinforcement followed by higher positive reinforcement on methadone. The Moderately Successful group showed more negative reinforcement before treatment but continued to show negative reinforcements afterwards. The Failures were low on negative reinforcements earlier but negative reinforcements were high after treatment.
