Research Bio

Dr. Pfund’s research program focuses on understanding the effects of psychological treatments for addictive behaviors, including gambling disorders and substance use disorders. Specifically, he is interested in what makes treatments work and how to tailor them to specific patients. Past research projects have focused on the association between treatment engagement (e.g., psychotherapy attendance, contingency management participation) and outcomes. Dr. Pfund frequently leverages systematic review and meta-analysis to conduct this research, and his research has been supported by grants from the National Institute on Alcohol Abuse and Alcoholism, the International Center for Responsible Gambling, and the Tennessee Department of Mental Health and Substance Abuse.  

Current research projects center on the following broad questions:

  • Meta-analysis of the immediate and enduring effects of motivational interviewing for gambling disorder
  • Meta-analysis of the cognitive-behavioral treatment components for gambling disorder
  • Development a web-based portal to facilitate the initiation of gambling disorder treatment 
  • Systematic review on the state of the evidence for motivational interviewing for substance use disorder
