Exposure therapy for PTSD during pregnancy: a feasibility, acceptability, and case series study of Narrative Exposure...

Prenatal posttraumatic stress disorder (PTSD) is a significant complication of pregnancy linked to increased risk of adverse perinatal outcomes. Although 1 in 5 pregnant trauma-exposed individuals have PTSD, most PTSD treatment trials exclude participants who are pregnant, and none focus on treatment specifically during pregnancy. Moreover, access to mental health treatment is particularly challenging in low-resource settings with high rates of trauma. This study examined implementation of Narrative Exposure Therapy (NET), a short-term evidence-based PTSD treatment, in an urban prenatal care setting. Partial telehealth delivery was used to increase accessibility. Study aims were to examine (a) feasibility, (b) acceptability, and (c) case-based treatment outcomes associated with NET participation.

Eight pregnant participants (median age = 27, median gestational week in pregnancy = 22.5) received up to six sessions of NET with partial telehealth delivery. PTSD and depression symptoms were assessed at pre-treatment intake (T1), at each session (T2), and 1-week post-treatment (T3). A multiple case study approach was used to examine recruitment and engagement, retention, treatment completion, treatment barriers, use of telehealth, participants' experiences of treatment, and PTSD and depression symptoms.

Nine of the 16 participants (56%) who were invited to participate engaged in treatment, and one dropped out after the first session. Eight participants completed the minimum "dose" of 4 NET sessions (N = 8/9, 89%). Seven participants gave the highest ratings of treatment acceptability. The most frequently reported barriers to treatment were competing priorities of work and caring for other children. Pre-post treatment symptom measures revealed clinically meaningful change in PTSD severity for nearly all participants (7/8, 88%).

Results suggest that a brief exposure therapy PTSD treatment can be successfully implemented during pregnancy, suggesting promising results for conducting a larger-scale investigation.
