J. Aaron Johnson, PhD

Interim Director, Institute of Public and Preventive Health
Assistant Division Chief, Health Services Research, Institute of Public and Preventive Health
Associate Professor, Department of Psychological Sciences
Associate Professor, School of Graduate Studies

Dr. Johnson’s research is focused on the implementation of evidence-based practices in substance abuse prevention and treatment. More recently, his research has incorporated technology as a means of enacting behavior change within this field.  

Dr. Johnson has published several validation studies of brief alcohol and/or drug screening tools for use in general medical settings as well as studies examining the implementation of alcohol and drug screening and brief intervention (SBI) in medical settings including primary care, emergency department, trauma unit, and urgent care.  He is the principal investigator of one training grant and the director of evaluation on 2 additional training grants funded by SAMHSA to provide alcohol and drug screening and brief intervention training to health professionals across many disciplines. These projects have resulted in several publications and numerous presentations describing the changes in knowledge, attitudes and behavior resulting from this training.

In addition to these training grants, Dr. Johnson is currently conducting a pilot study using an existing smartphone app, developed as a recovery support tool for alcoholics leaving addiction treatment, with recent parolees identified as high risk for substance use disorders. The intervention group receives a smartphone with app while the control group receives supervision as usual. Follow-ups conducted at 1, 3, and 6 months post-release will determine if the app reduces alcohol and drug use days.
