Online trauma psychoeducation for people with depression and comorbid PTSD symptoms: A pilot randomized controlled trial

Introduction Depression is commonly comorbid with post-traumatic stress disorder (PTSD) symptoms. There is a lack of studies evaluating trauma-informed interventions for people with depression and PTSD symptoms. Objectives We examined whether an online, easily accessible, trauma psychoeducation program would be helpful for people with both depressive and PTSD symptoms. Methods Participants with depression (PHQ-9 ≥ 10) and co-occurring PTSD symptoms were recruited online and randomly assigned to the intervention group (i.e., a 10-session online program based on Be a Teammate With Yourself ) or the control group. Outcome measures included the Brief-COPE, a subscale of the Endorsed and Anticipated Stigma Inventory, and the Post-traumatic Maladaptive Beliefs Scale. These outcomes were assessed at baseline, posttest, and 2-month follow-up. Qualitative feedback was also obtained from the participants. Results 35 participants were randomly assigned to the intervention group, and 34 to the control group. With only email reminders, 9 participants in the intervention group and 14 in the control group completed posttest and follow-up surveys. Completers-only analyses were conducted. One-way repeated measures ANOVA showed that the intervention group had significant reductions in post-traumatic maladaptive beliefs, with a large effect size (F = 4.152, p = .035, Partial Eta Squared = 0.342). The control group did not have such changes. Both groups did not have significant changes in coping and self-stigma. Of 12 participants who provided feedback, 100% agreed that the program could help them remain hopeful for recovery, and 91.6% agreed that they were satisfied with the program. The qualitative feedback also supported the usefulness and acceptability of the programme. Conclusions Participation in this program was associated with significant decreases in post-traumatic maladaptive beliefs. Completers were satisfied with the program. Given a small sample with a high dropout rate (66.6%), the results should be interpreted with caution. Disclosure of Interest None Declared
