Feasibility and Efficacy of GTEP for Birth Trauma

February 18, 2026 updated by: University of Birmingham

A Study to Explore the Feasibility and Efficacy of Group Traumatic Episode Protocol (GTEP) for Reducing Trauma Symptoms Following a Traumatic Birthing Experience

This clinical study aims to evaluate the feasibility and initial efficacy of Group Traumatic Episode Protocol (GTEP) for reducing trauma symptoms (measured by the PCL-5 and City BiTS) for individuals following a traumatic birthing experience. A secondary aim is to evaluate the efficacy of GTEP in improving parental wellbeing (measured through the CORE-10) and parent-infant bonding (measured through the PBQ) following a traumatic birthing experience.

Participants (those who have experienced a traumatic birthing experience) will complete the GTEP intervention, delivered online. They will be asked to complete outcome measures and give feedback on their experience of the group.

Study Overview

Detailed Description

It is estimated that up to 15.7% of individuals will experience some trauma symptoms following childbirth, with 4-6% developing Post-Traumatic Stress Disorder. Research has found there to be an increased risk of postpartum depression, postpartum psychosis and anxiety following a complicated or traumatic childbirth, along with reduced parent-infant bonding at 1, 6 and 12-months postpartum. Group Traumatic Episode Protocol (GTEP) is a version of Eye Movement Desensitization and Reprocessing (EMDR) to be used in group settings. There is a growing evidence base for the efficacy of GTEP in other populations and it has been found to reduce trauma symptoms in a refugee population, adult cancer patients and healthcare professionals . However, there is no research to date exploring the feasibility and efficacy of GTEP for trauma symptoms related to birth.

This study aims to evaluate the feasibility and efficacy of GTEP for reducing trauma symptoms (measured by the PCL-5 and City BiTS) for individuals following a traumatic birthing experience. Feasibility / acceptability will be evaluated using structured measures, along with open-ended qualitative questions. The facilitators of the group will also be administered these measures and asked for qualitative feedback about their experience of facilitating the group.

A secondary aim is to evaluate the efficacy of GTEP in improving parental wellbeing (measured through the CORE-10) and parent-infant bonding (measured through the PBQ) following a traumatic birthing experience

The GTEP Intervention (for use in this study):

The intervention will involve a total of 8 sessions:

  • Session 1: a home visit to gain consent, determine full eligibility and complete outcome measures.
  • Sessions 2 - 7: 6 online GTEP sessions, conducted via Zoom, which will happen weekly. Each session will last approximately 90 minutes.
  • Session 8: A post-group follow-up, either face-to-face or over the telephone, to discuss experiences of the group, discuss any onward referrals (as required), complete final outcome measures.

Study Design:

This study will use a pre-post design, with outcome measure questionnaires (CORE-10, City BiTS, PBQ) completed at two time points (before and after the GTEP intervention). In addition, the primary outcome measure of the PCL-5, will be administered at 8 time points (i.e., during the pre-intervention home visit, before sessions 2, 3, 4, 5, 6 and 7 and during the post-intervention follow-up).

A study feasibility measure will also be administered to evaluate the feasibility of the intervention for this population. This will be administered to both client participants and the group facilitators, where appropriate. Qualitative feedback will also be gathered.

A further qualitative component will also be utilised. In order to gather more feedback from facilitators of G-TEP, stakeholders / professionals from around the country who have used, or are considering using G-TEP, with individuals who have experienced birth trauma will be recruited to complete an online questionnaire. These participants will be recruited via social media adverts. They need to be UK-based to be eligible to take part. Consent forms and PIS will be sent via email and once these have been returned, a link to an online questionnaire (via MS Forms) will be sent.

Participants:

Participants will be recruited via the Black Country Perinatal Mental Health Service (BCPMHS) who are self-reporting trauma symptoms related to a traumatic birthing experience within the last 18 months.

Data Analysis:

Data will be analysed at the University of Birmingham. Quantitative data analysis will include a pre-and-post-intervention comparison scores at both an individual (using a Reliable Change Index) and a group level (using either a bootstrapped paired samples t-test or a matched-pairs Wilcoxon). Descriptive statistics will also be used where appropriate.

Qualitative analysis may be conducted related to the feasibility questions outlined above.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: GTEP
Participants will receive the GTEP intervention, delivered online.

GTEP is a group version of the Recent Traumatic Episode Protocol (R-TEP), a form of EMDR.

The GTEP intervention will involve 2 sessions focusing on preparation (e.g., through grounding and emotional regulation) followed by 4 processing sessions.
