Psychosocial factors in outcome in two opiate addiction treatments

Thirty naltrexone and 30 methadone patients in outpatient opiate addiction treatment were compared on pretreatment somatization, stress, and family support. Also, the relationship between these pretreatment variables and outcome in terms of drug abuse and retention was examined. In the methadone group, drug abuse was correlated significantly with somatization, stress, and family support. In the naltrexone group, retention was correlated significantly with somatization and stress. Treatment and research considerations were discussed.
