Abstract

This study aimed to examine the effectiveness of the Written Exposure Therapy (WET) program on posttraumatic stress dis- order (PTSD), depression symptoms, and posttraumatic growth among individuals with interpersonal trauma. To this end, participants (n =20) who had experienced at least one interpersonal trauma and scored 18 or more on the Impact of Event Scale (IES) were recruited. Participants were randomly assigned to an experimental (n =10) or waitlist control group (n =10). The experimental group completed eight weekly WET sessions. Assessments were conducted at baseline, post-intervention, and at four weeks following the intervention. Significant interaction effects were found between group and time of measure- ment for PTSD, depression symptoms, and posttraumatic growth. Additionally, significant differences were observed between the groups over time. These results demonstrated that the WET program significantly decreased PTSD and depression symp- toms, while increasing posttraumatic growth. These effects were sustained at the four-week follow-up. These findings suggest that the revised WET program may be effective as an intervention strategy for PTSD in future counseling and clinical settings.
