title: Effectiveness of abstinence-based incentives: interaction with intake stimulant test results.
abstract: Intake urinalysis test result (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 (N. M. Petry, J. M. Peirce, et al., 2005) 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.
