The Trauma PORTAL-A Blended e-Health Intervention for Survivors of Childhood Interpersonal Trauma: An Open-Label Pilot Study

Background: Adults with mental health symptoms stemming from childhood interpersonal trauma require specialized trauma-focused psychological interventions. Limitations in accessing treatment interventions for this population necessitate innovative solutions. This study explored the feasibility of a protocol for a blended e-health psychoeducational treatment intervention for this population called the Trauma PORTAL (Providing Online tRauma Therapy using an Asynchronous Learning platform), combining asynchronous online modules and weekly live virtual group sessions.Method: From October 2021 to February 2022, this prospective, single-arm study recruited participants who were waitlisted for trauma therapy at an academic hospital. The primary outcome was protocol feasibility, including recruitment, adoption, and intervention acceptability. Secondary outcomes were pre- and post-intervention post-traumatic stress disorder (PTSD) symptoms (PTSD Checklist for DSM-5 [PCL-5]), depression/anxiety/stress (Depression and Anxiety Stress Scale [DASS-21]), and emotion regulation (Difficulties in Emotion Regulation Scale [DERS-18]), which were compared using paired t-tests and presented as mean differences (MDs) and 95% confidence intervals (CIs).Results: A total of 66 participants (median age = 37, female = 61) were enrolled, and they completed on average 53.5% of the online modules. There were 51 (77%) participants who completed post-intervention questionnaires. Acceptability was very high, with 49 respondents (98%) reporting that the intervention increased their access to health care. There were reductions from pre- to post-intervention on the PCL-5 (49.1 vs. 36.7, MD -12.4, 95% CI 8.3-16.5), DERS-18 (51.8 vs. 48.8, MD -3.3, 95% CI 0.2-6.4), and DASS-21 (60.1 vs. 50.7, MD -9.4, 95% CI 2.3-16.6).Conclusion: The Trauma PORTAL intervention was feasible to implement, well-adopted, and highly acceptable in an ambulatory trauma therapy program. The findings show promising evidence for symptom reduction. Further evaluation of the Trauma PORTAL's efficacy in a randomized trial is warranted.
