Evaluating Three Methods for Helping Syringe Exchangers Begin Methadone Maintenance

Summary

This research is being done to evaluate the effectiveness of three different treatment strategies for helping subjects begin and adjust to methadone maintenance treatment at Addiction Treatment Services (ATS). Subjects will be randomly assigned to one of three treatment conditions: 1) Voucher-Based Stepped Care (VBSC) induction, 2) Low-threshold Stepped Care (LTSC) induction, or 3) Routine Stepped Care (RSC) induction. It is hypothesized that subjects in both the VBSC and LTSC condition will remain in treatment longer than subjects in the RSC condition. In addition, it is hypothesized that VBSC and LTSC subjects will have less drug-positive urine samples and will report less infectious disease risk behaviors than RSC subjects.

Interventions

BEHAVIORAL

Low intensity care

During the first 3-months (13 weeks), subjects will be scheduled to attend one individual counseling session per month. Subjects will not be required to attend any group counseling sessions during this time. After the first 3-months of care, subjects will start usual counseling care, at which time they will be required to attend one individual counseling session per week, and may be required to attend additional individual and group counseling sessions each week for missed sessions or continued use of drugs or alcohol.

BEHAVIORAL

Voucher reinforcement

Subjects will receive usual counseling care during the 26 weeks of study participation.They will be required to attend one individual counseling session per week, and will be required to attend additional individual and group sessions each week for missed session or continued use of drugs or alcohol.In addition, subjects in this condition will have the opportunity to earn voucher incentives each week during the first 13 weeks of care.These incentives can be earned by taking daily methadone doses and attending all scheduled counseling sessions (individual and group).The first voucher is worth $12.00, and each voucher after that is worth an additional $13.50. Bonuses of $30.00 will be awarded for each 3 consecutive weeks of compliance.The total amount possible to earn in the study is $1329.00. Each week that the subject is not compliant,they will not earn a voucher and the value of the next voucher will be reset to $12.00.The vouchers can be used for goods and services in the community.
