Abstract

Introduction: The primary study goal was to assess the feasibility of implementing a Randomized Clinical Trial (RCT) of Mindfulness-Based Relapse Prevention (MBRP) in a substance use and methadone clinic using a neuropsychological framework. Methods: Participation interest, retention rates, and feasibility of study design were examined. 13 participants were randomized to waitlist (n = 6) or MBRP (n =7). Associations between baseline variables and retention were examined. Executive function (EF) performance and topological properties of fNIRS resting-state networks were assessed. Results: Power was limited, but quantity of outside treatment was associated with retention. EF was variable, but within the average range. Network analyses revealed small world parameters in resting-state networks using fNIRS. Exploratory correlation analyses between EF and graph metrics were performed. Conclusions: The feasibility of using neuropsychological measures of EF and fNIRS in the context of a RCT in an outpatient substance use clinic was demonstrated.
