Valentine A1 - AB - OBJECTIVE: This pilot open trial examined the feasibility, acceptability, and preliminary effectiveness of Written Exposure Therapy (WET), a 5-session evidence-based intervention for posttraumatic stress disorder (PTSD) during pregnancy. Participants were pregnant women with comorbid PTSD and substance use disorder (SUD) receiving prenatal care in a high risk obstetrics-addictions clinic. METHODS: A total of 18 participants with probable PTSD engaged in the intervention, and 10 completed the intervention and were included in outcome analyses. Wilcoxon's Signed-Rank analyses were used to evaluate PTSD and depression symptoms and craving at pre-intervention to post-intervention and pre-intervention to the 6-month postpartum follow-up. Engagement and retention in WET and therapist fidelity to the intervention manual were used to assess feasibility. Quantitative and qualitative measures of patient satisfaction were used to assess acceptability. RESULTS: PTSD symptoms significantly decreased from pre-intervention to post-intervention (S = 26.6, p = 0.006), which sustained at the 6-month postpartum follow-up (S = 10.5, p = 0.031). Participant satisfaction at post-intervention was high. Therapists demonstrated high adherence to the intervention and excellent competence. CONCLUSIONS: WET was a feasible and acceptable treatment for PTSD in this sample. Randomized clinical trial studies with a general group of pregnant women are needed to expand upon these findings and perform a full-scale test of effectiveness of this intervention.
