title: Predicting postprimary treatment services and drug use outcome: a multivariate analysis.
abstract: The substance abuse treatment field is continually challenged to develop interventions that encourage drug abusers to remain longer in therapeutic services and that facilitate improved outcomes. As one of those interventions, case management has generally not been subjected to multivariate analysis to evaluate its role in accomplishing those goals. Using a sample of 444 veterans who received substance abuse treatment services, this study examines relationships among demographic and psychosocial variables at intake, assignment to either traditional or enhanced (case management) treatment services, and both proximal (postprimary treatment contact) and distal (severity of drug use) measures of outcome. Multivariate analyses reveal that case-managed clients stay longer in postprimary treatment services than non-case-managed clients, and consequently, longer postprimary treatment contact leads to better drug use outcomes. The implications of these findings are discussed.
