Intake urinalysis test results (drug positive vs. negative) has been previously identified as a strong predictor of drug abuse treatment outcome, but there is little information about how this prognostic factor may interact with the type of treatment delivered. The authors used data from a multisite study of abstinence incentives for stimulant abusers enrolled in outpatient counseling treatment (protocol CTN-0006) to examine this question. The first study urine was used to stratify participants into stimulant negative (n = 306) versus positive (n = 108) subgroups. Abstinence incentives significantly improved retention in those testing negative but not in those testing positive. Findings suggest that stimulant abusers presenting to treatment with a stimulant-negative urine benefit from abstinence incentives, but alternative treatment approaches are needed for those who test stimulant positive at intake.
