- University of Missouri, St. Louis
- Brief Summary
This randomized controlled trial (RCT) will examine the feasibility, acceptability, and preliminary efficacy of a beginning treatment for Post-Traumatic Stress Disorder (PTSD) with Behavioral Activation (BA). Cambodian men and women who screen positive for PTSD will be randomized to receive six individually delivered sessions of either: 1) Stabilization Techniques alone (ST); or 2) ST+BA. After two months, all participants who continue to report clinically meaningful elevations in PTSD will receive Eye Movement Desensitization Reprocessing (EMDR). All participants will complete a follow-up assessment at four months post-randomization.
- Detailed Description
Nearly half of the Cambodian population reports elevated levels of psychological distress and PTSD. The high levels of psychological distress are linked directly to the report of remote and more recent trauma exposures, the most notable of which is the agrarian political regime of the Khmer Rouge during the 1970s, which occurred in the aftermath of the Vietnam War. During this period, approximately 1.5 million Cambodian residents died of starvation and sickness, 500,000 individuals were executed, and another two million were displaced over the course of several years. Political stability took shape in the early 1990s after the enactment of the United Nations Transitional Authority in Cambodia. However, the prior violence undermined an already fragile healthcare system, including mental health institutions and physicians providing direct patient care.
The combination of high trauma exposure, sustained conflict, and limited psychiatric capacity has created heightened vulnerability for Cambodians, and the need to assist those struggling with PTSD. There is a pressing need to reverse this trajectory using novel approaches to address mental health needs that are effective and scalable, providing a strong basis to conduct the proposed work in Cambodia. In partnership with the Cambodian Department of Mental Health and Substance Abuse, Ministry of Health, this NIH-sponsored study will examine the feasibility, acceptability, and preliminary efficacy integrating BA into trauma treatment that is being delivered by the Mekong Project in Cambodia.

Group Intervention Description Stabilization Techniques (ST) Stabilization Techniques (ST) Participants randomized into ST will receive 6 weekly 1-hour sessions of Stabilization Techniques from a Khmer-speaking mental health professional. Sessions provide an opportunity to improve emotion regulation and provide coping skills for managing symptoms of PTSD. Participants will complete a follow-up assessment 2 months after randomization in which PTSD symptoms will be re-assessed using the PTSD Checklist (PCL-5) for the Diagnostic and Statistical Manual for Mental Disorders (DSM-5). Those who exhibit a 50% reduction in PTSD symptoms from baseline and no longer meet criteria for PTSD will be designated as responders and will receive no further treatment. Participants who continue to display clinically meaningful elevations in PTSD symptoms (i.e., non-responders) will receive EMDR, which is the standard of care for trauma treatment in Cambodia. EMDR sessions will be delivered by a Khmer-speaking mental health professional. Stabilization Techniques with Behavioral Activation (ST+BA) Stabilization Techniques with Behavioral Activation (ST+BA) Participants randomized into ST+BA will receive 3 weekly 1-hour sessions of ST and 3 weekly 1-hour sessions of BA from a Khmer-speaking mental health professional. Sessions include stabilization techniques and behavioral skills that aim to establish and maintain routines, reduce avoidance, and manage negative emotions. Participants will complete a follow-up assessment 2 months after randomization in which PTSD symptoms will be re-assessed using the PTSD Checklist (PCL-5) for the Diagnostic and Statistical Manual for Mental Disorders (DSM-5). Those who exhibit a 50% reduction in PTSD symptoms from baseline and no longer meet criteria for PTSD will be designated as responders and will receive no further treatment. Participants who continue to display clinically meaningful elevations in PTSD symptoms (i.e., non-responders) will receive EMDR, which is the standard of care for trauma treatment in Cambodia. EMDR sessions will be delivered by a Khmer-speaking mental health professional. Stabilization Techniques (ST) Eye Movement Desensitization and Reprocessing (EMDR) Participants randomized into ST will receive 6 weekly 1-hour sessions of Stabilization Techniques from a Khmer-speaking mental health professional. Sessions provide an opportunity to improve emotion regulation and provide coping skills for managing symptoms of PTSD.

Stabilization Techniques with Behavioral Activation (ST+BA) Eye Movement Desensitization and Reprocessing (EMDR) Participants randomized into ST+BA will receive 3 weekly 1-hour sessions of ST and 3 weekly 1-hour sessions of BA from a Khmer-speaking mental health professional.

- Primary Outcome Measures
Name Time Method Percent of study participants who no longer screen positive for PTSD at four months using the PCL-5 questionnaire. 4 months
- Secondary Outcome Measures
Name Time Method Culturally-Relevant PTSD Symptoms 4 months The Cambodian Symptom and Syndrome Inventory (CSSI) is a culturally validated measure of PTSD symptoms that yields a total score ranging from 0-148, with higher scores indicative of greater symptomatology.
Alcohol and Substance Use 4 months The Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) provides validated composite scores indexing the severity of alcohol and other substance use (Mild = 0-3; Moderate = 4-26; Severe = 27 or greater).
Psychological Distress 4 months The Depression, Anxiety and Stress Scale (DASS-21) is a validated measure of psychological distress that yields domain scores ranging from Normal (depression=0-4; anxiety=0-3; stress=0-7) to Extremely Severe (depression=14+; anxiety=10+; stress=17+).
