Voucher incentives increase treatment participation in telephone-based continuing care for cocaine dependence.

BACKGROUND: Telephone-based monitoring is a promising approach to continuing care of substance use disorders, but patients often do not engage or participate enough to benefit. Voucher incentives can increase retention in outpatient treatment and continuing care, but may be less effective when reinforcement is delayed, as in telephone-based care. We compared treatment utilization rates among cocaine-dependent patients enrolled in telephone continuing care with and without voucher incentives to determine whether incentives increase participation in telephone-based care. METHOD: Participants were 195 cocaine-dependent patients who completed two weeks of community-based intensive outpatient treatment for substance use disorders and were randomly assigned to receive telephone continuing care with or without voucher incentives for participation as part of a larger clinical trial. The 12-month intervention included 2 in-person orientation sessions followed by up to 30 telephone sessions. Incentivized patients could receive up to $400 worth of gift cards. RESULTS: Patients who received incentives were not more likely to complete their initial orientation to continuing care. Incentivized patients who completed orientation completed 67% of possible continuing care sessions, as compared to 39% among non-incentivized patients who completed orientation. Among all patients randomized to receive incentives, the average number of completed sessions was 15.5, versus 7.2 for patients who did not receive incentives, and average voucher earnings were $200. CONCLUSIONS: Voucher incentives can have a large effect on telephone continuing care participation, even when reinforcement is delayed. Further research will determine whether increased participation leads to better outcome among patients who received incentives.

An integrated drug counseling and employment intervention for methadone clients.

After drug use stabilization, employment has long been considered an important goal for clients enrolled in Methadone Maintenance Treatment Programs (MMTPs). The integrated counseling and employment intervention described here is a manualized treatment based on interpersonal cognitive problem solving (ICPS) theory. The six-month intervention utilized a problem-solving framework to help methadone clients obtain a job and manage employment within the context of drug treatment. In this pilot study, 23 subjects were randomly assigned to either integrated ICPS drug and employment counseling (n = 12) or to an ICPS drug counseling control condition (n = 11). While there were no differences between the integrated and control conditions, both groups showed a significant improvement in employment outcomes and reduction in HIV risk behaviors at the six-month follow-up. Although there may be concerns regarding the generalizability of the findings, overall, the problem solving framework may be an improvement over standard methadone counseling. The intervention may be beneficial when implemented with a larger group of motivated ex-offenders who are mandated to drug treatment as a condition of their parole.
