One in Ten Women Develops PTSD Symptoms After Induced Vaginal Delivery
Approximately 10.6% of women met a PTSD symptom profile two months after induced vaginal delivery (corrected prevalence 10.6%, 95% CI 8.1–13.7), with postpartum hemorrhage carrying nearly a fivefold increase in risk (aOR 4.9, 95% CI 1.8–13.3). Beyond established psychosocial vulnerability factors, specific features of the induction process itself — including cervical ripening and induction for fetal indications — emerged as independent contributors to PTSD risk.
What Was Studied
This study set out to estimate how common postpartum PTSD is among women who undergo induced labor followed by vaginal delivery, and to identify which clinical and psychosocial characteristics are associated with elevated risk. PTSD following childbirth in the context of labor induction has remained poorly characterized, and understanding its specific drivers is necessary to identify which women may benefit from targeted support.
How It Was Studied
This was an ancillary cohort study nested within the TRAAP randomized controlled trial, which enrolled women across 15 French university hospitals between 2015 and 2016. Eligible participants were women with induced labor who delivered a singleton vaginally after 35 weeks of gestation. Of the 794 women who met inclusion criteria, 560 completed questionnaires (70.5% response rate). PTSD symptom profile was assessed at two months postpartum using two validated self-administered screening instruments — the Impact of Event Scale-Revised (IES-R) and the Traumatic Event Scale (TES). Inverse probability weighting was applied to correct for nonresponse bias, and multivariate logistic regression was used to evaluate associations with potential risk factors.
What Was Observed
- The corrected prevalence of PTSD symptom profile at two months postpartum was 10.6% (95% CI 8.1–13.7), meaning roughly one in ten women who delivered vaginally following induction screened positive for PTSD.
- Postpartum hemorrhage of 1000 mL or more was associated with nearly five times the odds of PTSD compared to those without significant hemorrhage — the strongest single obstetric predictor identified (aOR 4.9, 95% CI 1.8–13.3).
- Induction performed for a fetal indication was associated with about two-and-a-half times higher odds of PTSD (aOR 2.6, 95% CI 1.2–5.5), and the use of cervical ripening as part of the induction process was linked to approximately double the odds (aOR 2.0, 95% CI 1.1–3.6), suggesting that procedural elements of induction contribute independently to PTSD risk.
- Negative subjective recall of the delivery experience at two days postpartum was associated with more than three times the odds of PTSD at two months (aOR 3.6, 95% CI 1.5–10.3), highlighting early psychological response as a potential marker of risk.
Why This Matters
Labor induction represents a clinically common obstetric intervention, yet this study indicates that the PTSD burden specifically within this group — at roughly one in ten women — is substantial and not fully explained by pre-existing psychosocial vulnerability. The finding that induction-specific procedural factors, such as cervical ripening and the indication for induction, are independently associated with PTSD suggests these elements of care may themselves shape the psychological experience of childbirth. Early subjective distress, captured at day two postpartum, may offer a clinically accessible window for identifying women who warrant closer follow-up.
How to Read This Result
These findings should be interpreted with caution: the study relies on self-administered screening questionnaires rather than formal diagnostic interviews, the cohort was drawn from a trial not designed to measure PTSD, response bias may persist despite statistical correction, and the absence of a spontaneous-labor comparison group limits conclusions about whether induced delivery independently elevates PTSD risk relative to other birth types.
Limitations
As an ancillary study of the TRAAP trial — an RCT designed to evaluate postpartum hemorrhage prevention — the dataset was not originally structured for PTSD research, which constrains the scope and depth of PTSD-relevant variables available for analysis. The 70.5% questionnaire response rate introduces potential nonresponse bias, which the investigators addressed through inverse probability weighting but cannot fully eliminate. Screening questionnaires, while validated, do not substitute for structured clinical interviews in confirming PTSD diagnoses, and some misclassification is likely. Critically, there was no concurrent comparison group of women with spontaneous labor, making it impossible to directly quantify whether induction itself raises PTSD risk above baseline levels seen in unplanned or spontaneous deliveries.
