What this trial studies

This clinical trial aims to evaluate the effectiveness of Group Written Exposure Therapy (G-WET) in reducing symptoms of Posttraumatic Stress Disorder (PTSD) among participants. The study involves six weekly online sessions led by two therapists, where participants will engage in therapeutic writing exercises and complete questionnaires to assess their symptoms. Researchers will compare the outcomes of G-WET with those of group Cognitive Processing Therapy (CPT) to determine its efficacy and dropout rates. The study will recruit 63 individuals aged 18 to 65 who are on a waitlist for group CPT.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have a diagnosis of PTSD and can read and write in English.

Not a fit: Patients with active severe substance use disorders, psychotic disorders, or those who have recently engaged in high-risk self-harm may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could provide an effective treatment option for individuals with PTSD, potentially leading to reduced symptoms and improved quality of life.

How similar studies have performed: Previous studies have shown success with individual Written Exposure Therapy, but this group approach is relatively novel and has not been extensively tested.
