Abstract This study's goals were to characterize the relationship between early and longer term cocaine abstinence and assess whether increasing early abstinence increases longer term abstinence. Results from 190 cocaine-dependent outpatients were analyzed. Participants were divided into 2 conditions: (a) those treated with community reinforcement approach (CRA) plus contingent vouchers (n = 125) and (b) those treated with control treatments (n = 65). A period of sustained abstinence during treatment was associated with significantly greater odds of posttreatment abstinence, with no evidence of differences between the 2 treatment conditions in that regard. Treatment conditions differed in that CRA plus contingent vouchers increased the proportion of participants who sustained a period of during-treatment abstinence and increased abstinence during 6-month posttreatment follow-up. Devising interventions that increase the proportion of individuals who achieve an early period of sustained abstinence may be key to increasing longer term cocaine abstinence.
