The primary goal of this investigation is to evaluate sleep, performance, and neurocognitive effects among a sample of methamphetamine-dependent participants (n=10) and a sample of prescription opioid-dependent participants (n=10) during active substance use and during a cessation period over the course of a 6-week contingency management (CM) protocol. Additionally, we plan to obtain and evaluate background characteristics, subjective and biological measures of polysubstance use, measures of chronic pain (both psychological and physiological), craving for methamphetamine and prescription opioids, and mood during active substance use and cessation periods. The proposed contingency management (CM) study will utilize a within-subject ABA design (see Table 1). This design provides a powerful framework for evaluating CM efficacy while allowing for a small sample size.
