Debra Lee Kaysen
Professor of Psychiatry and Behavioral Sciences (Public Mental Health and Population Sciences)
Current Research and Scholarly InterestsMuch of my current research focus is on the development of testing of accessible, scaleable, and effective treatments for trauma-related disorders and related comorbidities (e.g. substance use disorders, HIV, mood disorders). This work has focused on addressing trauma-related disorders especially in underserved populations and settings. This includes research in rural communities, with Native American communities, and with sexual minorities. My research has had a strong impact on building an evidence base on adaptations of psychotherapies for PTSD and substance use disorders for diverse populations both within and outside the United States. Our findings demonstrate that complex cognitive behavioral psychotherapies like Cognitive Processing Therapy can be culturally adapted and delivered in challenging settings (conflict settings, high poverty environments) with significant and lasting change in PTSD, depression, and functioning. This has led to work adapting CPT for diverse populations within the United States (rural Native Americans, urban Latinos) and outside of it (Iraq, DRC). Other research has focused on treatment for PTSD/SUD. My research has also found support for the use of brief telehealth interventions to build treatment engagement and to reduce drinking among trauma-exposed populations. In addition, my work has been critical in testing the feasibility of novel trauma-focused interventions for use by those with PTSD and SUD, thus paving the road for more rigorous research studies.
Current PI'ed research studies include: 1) developing and evaluating a brief motivational interviewing intervention designed to increase treatment-seeking among military personnel with untreated PTSD; a two-arm randomized comparative effectiveness trial to evaluate prevention of HIV/STI sexual risk behavior by addressing PTSD through Narrative Exposure Therapy or substance use through Motivational Interviewing among Native American men and women with PTSD; and 3) a comparison of outcomes among patients randomized to initially receive pharmacotherapy or Written Exposure Therapy delivered in primary care as well as comparing outcomes among patients randomized to treatment sequences (i.e., switching and augmenting) for patients who do not respond to the initial treatment. -
