About Us

Who We Are

The Addictive, Compulsive and Impulsive Disorders (ACID) research/clinical group has a variety of treatment services and clinical trial opportunities available in the areas of substance addiction, impulse control, and obsessive compulsive disorder.  Through our work, we hope to better understand the biological underpinnings of these common conditions and facilitate better treatments and quality of life for clients and their families.  We also strive to advance awareness and decrease stigma of these disorders through public advocacy, presentation, and interaction with federal, industry, foundation, and community sources.

Our central areas of focus are in substance and behavioral addictions, including alcohol, drug, and tobacco dependency, pathological gambling, compulsive shopping, kleptomania (shoplifting), pyromania (fire setting), compulsive sexual addictions, obsessive-compulsive disorder (OCD), skin picking, trichotillomania (hair pulling) and body dysmorphic disorder. Our clinical group offers cognitive behavioral therapy for these disorders to new and existing patients in the Department of Psychiatry and Behavioral Neuroscience. Group treatment may also be available based upon need and client interest.

Impulse control disorders (ICDs) are often referred to as “behavioral addictions.” The term “behavioral” derives from the fact that patients with ICDs, in general, do not abuse a particular substance but rather engage in damaging behaviors such as gambling, shopping, shoplifting, fire setting, excessive grooming, etc. Akin to those with substance addictions, individuals with ICDs often report urges to engage in a behavior that gives them short-term pleasure or excitement. A goal of our research is to identify pharmacological and psychotherapeutic means of dampening these urges (cravings) that seem to lead to behavioral control.


We conduct research to elucidate pathophysiological links to addictions, ICDs, and OCD, and conduct clinical trials to develop improved treatments for our patients.

Andrea King

Associated Clinican, ACID clinic

Andrea King, Ph.D., is a Professor of Psychiatry & Behavioral Neuroscience.  She received her doctoral degree from the University of Oklahoma Health Sciences Center and completed her internship at the University of Pennsylvania. Dr. King’s primary goal is to examine the mechanisms of vulnerability to substance use disorders and to identify efficacious behavioral and pharmacological interventions for treatment of addiction.  The main focus of her research has concentrated on the etiology and treatment of alcohol and nicotine dependencies. Dr. King’s work in the Clinical Addictions Research Lab has particularly focused on individual differences among drug users and what factors contribute to developing chronic, maladaptive use of various drugs of abuse. She also focuses on improving clinical methodology for traditionally underserved minority groups. Her work has earned numerous institutional awards at both the University of Chicago and University of Oklahoma Health Sciences Center.  Additionally, students and post-doctoral mentees in her lab have won national awards from the Research Society on Alcoholism.
