Change in employment status and cocaine use treatment outcomes: A secondary analysis across six clinical trials

Abstract

BackgroundUnemployment is a chronic problem among treatment seeking substance users and is associated with poor treatment response. Most studies that have examined the relationship between employment and treatment outcomes for substance use disorders have done so by considering employment at only one specific point in time (e.g., upon entering treatment). There is a lack of research on how change in employment status over time is associated with substance use treatment outcomes. The aim of this study was to evaluate both static employment status and change in employment status over time as predictors of cocaine use treatment outcomes. MethodsWe utilized data pooled from six randomized clinical trials evaluating treatment for cocaine use disorders (n = 553). Multiple general linear mixed models were conducted to determine the association of baseline, end-of-treatment, and change in employment status (from baseline to end-of-treatment) with treatment outcomes. ResultsTreatment outcomes did not differ by baseline employment status but were significantly better for those employed versus unemployed at the end-of-treatment. In regard to change in employment status over time, those who were unemployed at baseline and acquired employment by end-of-treatment had significantly better treatment outcomes during active treatment and follow-up, as compared to those who were unemployed at baseline and remained unemployed by end-of-treatment. ConclusionOur findings suggest that end-of-treatment employment status may be an important marker of good outcome among those unemployed at treatment entry and support the incorporation of interventions designed to promote employment by substance use disorders treatment programs.
