Addictions Research Lab

Our work in the Addictions Research Lab is informed by social cognitive theory and cognitive behavioral and motivational enhancement treatment models.   Our research focuses on a variety of populations, including adult marijuana users, teen marijuana users, and Veterans.  Our work with adult, dependent marijuana users has primarily compared CBT interventions.  We have recently expanded into preliminary studies of continuing care with ongoing, brief "check-ups" in the follow-up period.  We have conducted various studies comparing brief interventions for marijuana reduction in the teen, high school, marijuana-using population.  These interventions have been primarily comprised of brief, Motivational Enhancement Therapy "check-ups" with optional continuing CBT therapy.  We have also collaborated with colleagues at the Salem, Virginia VA Medical Center on the evaluation of continuing care models of treatment for patients using contingency management and other behavioral principles.

Currently, we are working on a grant project funded by the National Institute of Drug Abuse studying the impact of motivational enhancement therapy for the reduction of marijuana use in adolescence with our partners in Seattle.  Additionally, we are working with the Virginia Tech College Alcohol Abuse Prevention Center to develop a brief marijuana intervention for college students.

The Addictions Research Lab is directed by Bob Stephens, professor and currently chair of psychology.  He trained as a clinical psychologist and received his PhD from Florida State University and then completed his postdoctoral work with Alan Marlatt at the University of Washington Addictive Behaviors Research Center.  His main research interests include substance abuse treatment efficacy, predictors of treatment outcome and etiology of substance abuse. Much of his work has focused on the treatment of marijuana dependence and has been funded by the National Institute on Drug Abuse.
