Written Exposure Therapy for Veterans With SUD and PTSD

This study is a randomized clinical trial within a Substance Use Disorder (SUD) specialty clinic to evaluate whether treatment as usual (TAU) plus Written Exposure Therapy (WET) is superior to TAU augmented by a neutral topic writing condition on both PTSD and addiction outcomes for Veterans in SUD treatment. Veterans with a current diagnosis of SUD and comorbid PTSD will be randomized to either WET plus TAU or TAU augmented by a neutral topic writing condition. During the first writing session, participants will be asked to write about either a personal traumatic experience (WET) or a neutral topic (control). In sessions 2 through 5, participants will again meet with the study therapist for 45 minutes (maintaining the same writing condition as assigned in session one). Measures of trauma symptoms, distress, and mood will be collected at each writing session, with additional assessments at baseline, at post-treatment (following 5 writing sessions), 8-weeks, and 12-weeks post-baseline assessment. The primary aim of this study is to examine whether WET augmentation of TAU improves trauma symptoms for Veterans with SUD and PTSD who are receiving outpatient SUD treatment compared to TAU with a neutral writing control. The secondary aim will examine whether WET improves SUD outcomes for Veterans with comorbid PTSD compared to TAU with a neutral writing control. If results prove promising, they will support WET as an effective brief, cost efficient, easy to disseminate, adjunct to current SUD treatment for Veterans with comorbid PTSD.
