One variation of contingency management involves providing vouchers with monetary value for the provision of a biological sample indicating no recent drug use. These vouchers can be exchanged for goods or services. The schedule with which the vouchers are disbursed has been studied and results suggest that those schedules that incorporate escalating magnitude of reinforcement for consecutive instances of abstinence and a reset contingency, which reduces the value of the vouchers for instances of use, seem to provide the best treatment outcome. In th is paper we explore several other scheduling arrangements while using the escalating schedule with a reset contingency as the comparator. The comparator schedule generally outperformed the other schedules in in itiating and in maintaining abstinence from methamphetamine.
