Parental relationships and substance use among methadone patients. The impact on levels of psychological symptomatology.

The relationship between parental substance use problems (SUPs) and the quality of parental relationships with levels of psychological symptomatology was examined in 155 female and 324 male methadone maintenance patients. Subjects completed the Beck Depression Inventory (BDI), SCL-90, and the Treatment Effectiveness Questionnaire (TEQ), which included questions regarding demographics, drug use, family/social relationships, and substance use in relatives. Of those completing the questionnaire, 40% were randomly selected for an Addiction Severity Index (ASI) interview. As hypothesized, parental SUPs were associated with greater levels of psychological symptomatology, more family/social, and medical problems. Positive parental relationships were associated with significantly lower levels of psychological symptomatology and fewer family/social problems. Males were significantly more likely than females to report positive parental relationships and no parental SUPs. No differences based on race were revealed related to reports of the quality parental relationships or parental SUPs.
