Cognitive Processing Therapy Or Relapse Prevention for Comorbid Posttraumatic Stress Disorder and Alcohol Use Disorder

A randomized clinical trial

About the Course

This study compared a Posttraumatic Stress Disorder (PTSD) treatment (Cognitive Processing Therapy; CPT), an Alcohol Use Disorder (AUD) treatment (Relapse Prevention; RP), and assessment-only (AO) for those meeting diagnostic criteria for both PTSD and AUD. Participants with current PTSD/AUD were initially randomized to CPT, RP, or AO and assessed post-treatment or 6-weeks post-randomization (AO). AO participants were then re-randomized to CPT or RP. Follow-ups were at immediate post-treatment, 3-, and 12-months. Mixed effects intent-to-treat models compared conditions on changes in PTSD symptom severity, drinking days, and heavy drinking days. Results and conclusions are presented.

This course is based on the reading-based online article, Cognitive Processing Therapy Or Relapse Prevention for Comorbid Posttraumatic Stress Disorder and Alcohol Use Disorder created by Tracy L. Simpson, Ph.D. et al. in 2022.
