Unmet service needs in methadone maintenance.
The extent to which these needs are met may be an important factor in client retention and outcomes. Perceived unmet service needs and their relationship to client outcomes were therefore studied in relationship to a framework for studying drug abuse treatment process factors. The results showed that the measure of unmet needs for services was not significantly related to time to relapse or to time in treatment. However, there appeared to be an indirect effect. There were differences for clinic type and a few significant interactions with other predictor variables used to study treatment process.
