Methadone maintenance outcome as a function of detoxification phobia.

Abstract

Methadone maintenance outcome as a function of detoxification phobia was examined. Opiate addicts (N = 271) in a 1983 random sample of methadone maintenance patients from three diverse populations were studied. Subjects from an individually assessed follow-up sample (N = 102) were compared on detoxification phobia. Logistic regression analysis yielded best predictors of the phobia. Phobic patients were more likely to be white, female, and abstinent; to have had fewer detoxification attempts and longer periods on maintenance; to show persistence of the phobia; to meet diagnostic criteria for depressive or anxiety disorders; and to have Addiction Severity Index scores above the 75th percentile for psychological problems. Detoxification phobia has a complex relationship to methadone maintenance outcome. It is associated with greater abstinence for patients in methadone maintenance treatment. However, for rehabilitated phobic patients it presents a barrier to successful detoxification and a drug-free adjustment that is often associated with other psychopathology but could be ameliorated by targeted assessment and treatment.
