Abstract

Voucher-based reinforcement therapy (VBRT) is an efficacious contingency management intervention for substance use disorders that provides escalating voucher values to reinforce continuous abstinence and typically resets escalated values to the initial low level upon detection of drug use. The objective of this study involving 130 methadone-maintained outpatients receiving VBRT was to investigate whether resets (a) increase risk for adverse events (AEs) and (b) delay return to abstinence in relation to magnitude of voucher reset. Weeks following resets were examined for increased likelihood of AEs using a Poisson regression. A Cox proportional hazards model was used to determine if higher resets increased the number of days until a negative urine specimen. Results showed that resets did not increase the likelihood of AEs nor were higher resets related to an increased delay to abstinence. Research involving larger samples is needed to produce sufficient data directly addressing safety concerns of various treatment stakeholders.
