Abstract:
:Despite depressive symptoms being very common among patients seeking treatment for cocaine dependence, few studies have examined the effects of depressive symptoms on cocaine outpatient treatment outcomes, and there is even less research in the context of Contingency Management (CM). The purpose of this study was to assess the main and interactive effects of co-occurring depressive symptoms on CM outcomes. Cocaine-dependent individuals (N = 108) were randomized to Community Reinforcement Approach (CRA) or CRA plus CM in two outpatient community clinical settings. Participants were categorized according to depression symptoms, self-reported by means of the BDI at treatment entry. Outcome measures included treatment retention and documented cocaine abstinence over a 6-month treatment period. Depressive symptoms were more commonly found in females and in unemployed participants, and were associated with more drug-related, social, and psychiatric problems at treatment entry. Individuals with baseline depressive symptoms had poorer treatment outcomes than patients without depressive symptoms. The addition of CM to CRA made the program more effective than with CRA alone, regardless of depressive symptoms. CM was associated with better abstinence treatment outcomes, while the interaction between unemployment and depressive symptoms was associated with negative retention treatment outcomes. This study supports the efficacy of CM for cocaine-dependent outpatients with and without depressive symptoms, and highlights its importance for improving treatment for unemployed and depressed cocaine-dependent individuals.
