Feasibility Trial of Narrative Exposure Therapy (NET) for Posttraumatic Stress Disorder (PTSD) During Pregnancy

Study Overview
=================
Brief Summary
-----------------
Posttraumatic stress disorder (PTSD) affects up to 35% of pregnant trauma survivors. Moreover, prenatal PTSD rates are up to 4 times higher among communities of color compared to white populations. PTSD during pregnancy has been linked to an increased risk of adverse perinatal and infant health outcomes and may even contribute to racial disparities in adverse perinatal outcomes. Although front-line treatments exist for PTSD, treatment research that specifically focus on pregnancy are extremely limited. Clinical studies examining the safety, acceptability, feasibility, and efficacy of treatments for PTSD during pregnancy are virtually non-existent. Thus, pregnant individuals with PTSD, particularly within low-income communities of color, are a vulnerable and underserved group in need of effective treatment approaches for their distress. Investigators propose to conduct a feasibility and acceptability study of a PTSD treatment, Narrative Exposure Therapy (NET), in a sample of pregnant individuals with PTSD in which low-income people of color are highly represented. Aim 1: The purpose of Aim 1 will be to examine feasibility. Investigators will evaluate the recruitment and assessment procedures. Aim 2: The purpose of Aim 2 will be to examine acceptability. Investigators will evaluate participant feedback of the NET intervention. Aim 3: The purpose of Aim 3 will be to examine the proportion of participants demonstrating clinically meaningful reduction in PTSD and perinatal depression symptoms from pre- to post-treatment. Investigators will aim to enroll up to 30 participants; participation will last up to ten months. Data sources will include questionnaires, electronic medical records, and qualitative feedback interviews. With this study, investigators aim to fill a critical gap in knowledge of how to safely and effectively treat PTSD among a vulnerable and underserved population (i.e., perinatal individuals of color).

Detailed Description
-----------------
Investigators will conduct a feasibility and acceptability study of Narrative Exposure Therapy (NET) to treat up to 30 pregnant trauma survivors with clinically-significant symptoms of PTSD. Up to 100 participants will be recruited with the aim of enrolling 30 participants in NET. Pregnant patients will be recruited from Rush OB/GYN resident training clinics. The racial/ethnic composition of patients served at these clinics (>70% ethno-racial minorities) will ensure that participants of color will be highly represented. Methods of recruitment include NET brochures that will be placed in the clinic's waiting rooms, OB/GYN physicians and nurse referring patients with a known history of trauma, and a 2-item screening measure -- the PTSD Checklist, Civilian Version (PCL-2) -- at the patient's initial OB appointment to facilitate recruitment. Following initial referral, the study team will conduct a brief phone screen to ensure basic eligibility criteria are met, describe the study purpose, and schedule eligible participants for an initial study session (week 0). During the initial visit participants will sign informed consent and complete self-report measures (week 1 of the study) - after which they will then be enrolled in the intervention (weeks 1-6 of the study). Participants will complete post-treatment self-report measures and treatment evaluation measures at 1 week and 1-month following their last NET session (week 7 and week 10, respectively), and again at 1-month postpartum. The participant will also be invited to complete a qualitative feedback interview upon completion of the intervention (or early withdrawal from intervention). Participants will be compensated for completion of all assessments and study components. Due to the Coronavirus/COVID-19 pandemic, all study activities will be conducted via telephone or telehealth. Schedule of Activities: Week 1: Consent and Pre-Intervention Clinical AND NET Session 1 Consent Session/Pre-Intervention Clinical interview Informed Consent: If patients are interested in participating in this study, they will undergo the informed consent procedure. A trained clinician with experience working with trauma survivors will verbally review the informed consent document. Interview and Self-Report Measures: Participation in Treatment while enrolled in the study: Patients may be in or seek psychological or psychiatric treatment and still enroll in the study, as long as they are not undergoing exposure therapy. If patients indicate that they are already or wish to seek such treatment, they will be asked to provide consent for study personnel to contact their mental health provider to obtain this single piece of information, as well as whether or not they are being prescribed anti-psychotics (which is a reason for study exclusion) NET Session 1 1. For each weekly session, the content of each session will be taken from the NET manual, a developed manualized treatment. The NET manual can be accessed here: https://www.psychologytools.com/category/narrative-exposure-therapy-net/ Weeks 2-6: Sessions 2-6 of NET 1. Participants will also complete self-report measures before the beginning of each NET session via REDCap. 1 Week Post-treatment: Post-treatment Evaluation 1 Month Post-treatment 10: Post-treatment Evaluation 1 Month Postpartum: Follow-up Evaluation Qualitative Feedback Interview (upon completion of the intervention or early withdrawal from intervention)

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Narrative Exposure Therapy<br>NET is a fully-manualized evidence-based treatment for PTSD. Participants will receive 6 weekly 60-minute individual sessions of NET. | Behavioral: Narrative Exposure Therapy<br>* NET involves: 1) diagnostic interview and psychoeducation, 2) laying out the Lifeline, 3) NET therapy sessions (constructing the trauma narrative in context of the life course), 4) final session rituals. Laying out the Lifeline (using rope or string) allows participants to take a bird's eye view of the events of their life using simple items such as flowers to represent positive events and stones to represent traumatic events. The focus of NET sessions is to encourage participants to describe the details of traumas and integrating the cold memories (i.e., facts) with the hot memories (e.g., cognitions, emotions, physiological feelings, and sensory information). The therapist makes notes after each session narrating the details of the traumas (stones) and reads this at the beginning of each subsequent session. Final session rituals involve re-reading the trauma narrative, hopes for the future, and laying out the final Lifeline placing flowers for hopes and wishes for the future.<br>* Other names: NET;|
