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

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.

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).

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).

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.
