Ensuring the well-being of women from the very early postpartum period is important for mother and child health. Research in the Dekel lab at Massachusetts General Hospital is focused on identifying the factors that are implicated in optimal adaptation as well as psychopathology of mothers following childbirth. To this end, we combine psychological, physiological and neuroimaging tools to prospectively study women from pregnancy across childbirth. Ultimately our goal is to develop novel tools for early detection of mothers at risk for postpartum mental disorders and preventive treatments that are effective and safe. 

Although childbirth is usually considered a uniformly happy event, some women may experience a traumatic childbirth. Some will go on to develop a postpartum posttraumatic stress disorder (PTSD), a condition we know very little about. We study the psychological and biological mechanisms underlying the various mental health trajectories in the wake of a traumatic delivery and what allows some women to be resilient and even grow psychologically. We are also interested in learning the ways in which distress in the mother may influence child development.

Patient Stories

There’s a recurrent theme among birthing people who experience a traumatic birth, only 20% seek treatment because there’s no formal diagnosis for postpartum PTSD. Women too often don’t know they’re suffering with the condition and can experience guilt and shame.

Increasing awareness of conditions of traumatic stress and associated post-traumatic stress disorder (PTSD), which is different and distinct from postpartum depression (PPD), after giving birth can help destigmatize postpartum PTSD, promote healing and a sense of ‘you’re not alone.’

Please be advised that the stories below are honest and powerful, though traumatic, stories of childbirth.

Emergency and/or unscheduled cesarean section (c-section)

“It’s after 6am and I wake up in my bed at the delivery room to see a group of nurses standing at my bedside looking very concerned. I immediately can tell that something’s not right. One of the nurses tells me that my baby’s heart rate has spiked really high and isn’t coming down. I start to panic and feel my heart beat faster and my stomach in knots. Two or three minutes later the nurses rush back in and one of them tells me that I need a c-section right now. I ask whether my partner can come and the nurse tells me they have to take me immediately. She puts a hairnet on me as they’re rushing me down the hall. I feel like I have no control. I hold on to my necklace with my daughter’s ashes and pray. I’m all alone and I’m terrified that I’ll lose this baby too.”

Recovery / immediate postpartum

“It’s the morning and I'm in the bathroom. I’ve just urinated. Now, I feel something large slide out of me as I stand up. Looking down, my face becomes flushed. There, on the pad in my underwear, I see a very large blood clot approximately the size of a lime. I’m feeling nauseous and my heart quickens. I fear that I’m bleeding again. With my hands trembling, I pull the nurses’ emergency line. Then, 3 nurses come running into the bathroom, and I see they look panicked. I feel lightheaded and jittery. I’m scared I need another surgery.”

Health of the fetus

“It’s around 11 am and I’m lying on a bed in the operating room and I’ve just had a c-section. They drop the curtain to show me my baby, and I feel sweaty as I look at her. She looks very red and swollen, and I know that something is wrong. My husband tells me that she has swelling on her head because she couldn’t fit, and I feel guilty because she was trying, and I wasn’t helping her. I feel exhausted as I think about what’s going to happen next. With tension in my forehead, I hear the constant chatter between the doctors, but no one will tell me if I’ll be able to do skin to skin and I feel sad.”

Obstetrical complications

“I’m lying cut open on the operating room table and blood rushes to my head. I don’t hear my baby crying, and I think that she’s not alive. They take my baby away, and I see my husband walk past me, looking at me with my insides exposed. The surgeon says, “I don’t like the placement of the bowel, let’s take it out and place it again.” I break out into a sweat and start to have a panic attack as my heart beats faster. Then, I begin to black out and my hands start to shake as I become nauseous.”

Medical complications

“It’s 11:00 pm and I’m lying on the operating room table with three IVs restricting my arms. My husband isn’t in the room and I’m all alone. Bright light shines on me, and my eyes become watery. Immediately I feel sick and begin to vomit. The nurse gives me a puke bag and I’m barely holding it between my left shoulder and chin. Only some of the vomit makes it in. I continue to shake vigorously and feel no control over what is happening. Now, the doctor tells me she needs to do a hysterectomy. My body feels heavy as I think I’ll lose my uterus. I’m concerned I may even lose my life.”

Staff Interactions

“It’s around 9:30 AM. I am in the labor and delivery unit propped up in a hospital bed with an IV, oxygen saturation monitor, and a fetal heart monitor on my belly. My husband is to the left of me, along with two nurses and a young male anesthesiologist elsewhere in the room. I feel tense all over and my heart begins to beat faster as I remember what happened during my last birthing experience. I ask the anesthesiologist if he had read my file in preparation for today. He says no and even shrugs when I describe my previous birthing experience. I want to scream, my jaw clenches and my stomach feels knotted, but I keep my emotions inside. I feel like everything is unraveling.”

Baby/mom attachment connection

“I’m lying on the birthing bed in the delivery room with my husband and the midwife holding my legs wide open. My heart races and I feel sweaty as the nurse tells me, “next push and she’s going to be here.” Suddenly, someone plops my baby onto me. With my eyes wide open, I look at her big purple face. It doesn’t feel like this is my baby and I feel disconnected, waiting for her to make a sound. Then, my palms are clammy as they quickly take her away and I feel shocked. She doesn’t look right, and I know that something is wrong.”

Current Lab Studies

Defining Postpartum PTSD and Its Implications for Maternal Wellness and Child Development (Harvard-MGH BIRTH study)

Maternal mental illness following childbirth is associated with substantial societal costs. An estimated 240,000 American women suffer from childbirth-related post-traumatic stress disorder (CB-PTSD) each year. Some may struggle with forming an emotional attachment to their infant. Yet, CB-PTSD remains largely underdiagnosed and undertreated, and we want to change this reality through state-of-the art research. This NIH-funded study aims to define the course and predictors of CB-PTSD and its effects on the child, and establish the foundation for preventive and holistic care for both mother and child. We are studying women from the time of pregnancy and at repeated times throughout the first postpartum year. Over 350 pregnant women have been enrolled in this study so far. The study is open to enrollment for women who receive their perinatal care at MGH.

Preventing Childbirth-Related PTSD With Expressive Writing (CARES)

There are no recommendations for interventions to prevent PTSD following childbirth. However, this form of PTSD is an ideal candidate for prevention because we know when the disorder develops, that is, after childbirth, and women are followed as part of routine care during this time period. In this first-of-its-kind study, we are testing whether a brief and early psychological intervention can prevent PTSD following a complicated, highly stressful delivery. The study is funded by the NIH and entails a randomized clinical trial, which is the state-of-the art study design in clinical research to determine whether a treatment is effective or not. Women are asked to write about their childbirth experience or neutral daily events in the first postpartum days. Our work furthers the NICHD’s mission that “women avoid harmful effects from reproductive processes and children achieve healthy and productive lives.” ClinicalTrials.gov IDNCT05662423. The study is open to enrollment for women who receive their perinatal care at MGH.

Dekel Lab: Global Mental Health Initiative: Harvard-Israel Birth Study

Although large-scale man-made trauma remains a global threat, our knowledge about the impact of terrorism and war on birth outcomes is scarce. This is in part because it is difficult to develop a study during times of crisis. We are collaborating with teams in Israel to study the impact of the October 7th massacre and the Israel-Hamas War on pregnant and postpartum women residing in Israel. Our goal is to collect critical information on women’s mental health and understand how heightened levels of stress may affect birth outcomes. We have enrolled over 800 women so far. Here is the study advertisement:

Calling all pregnant women and women who recently gave birth! Harvard University and Massachusetts General Hospital researchers in consultation with physicians and researchers from hospitals in Israel are examining the impact of the October 7th massacre on women’s wellbeing. Complete a survey.

Dekel Lab: Global Mental Health Initiative: Nigerian Obstetric Wellness (NOW) Project

The study of maternal mental health in developing countries is lacking. Unfortunately, rates of maternal death remain high in certain regions of the world, and accordingly, so do severe complications in childbirth that likely result in developing PTSD. Nigeria is among the leading countries in which the state of maternal mental health is poor: 1,047 out of 100,000 women die from complications related to pregnancy and childbirth, with an associated psychological toll. We have collaborated with the Obstetrics and Gynaecology Department of the University College Hospital in Ibadan, Nigeria (Site PI: Prof. Adesina Oladokun) to perform the first-ever study on traumatic childbirth and PTSD. We are investigating the prevalence of maternal PTSD and its risk factors by studying patients in this hospital. We are interested in revealing how social determinants of health, as well as the actual practice of perinatal care, impacts women’s well-being.

Preventing Postpartum Depression with Oxytocin

Our NIH funded clinical trial introduces a novel therapeutic approach with the use of oxytocin administered to mothers at risk immediately following childbirth. We are testing whether oxytocin, an anxiolytic and pro-social hormone, can reduce postpartum depression and anxiety and boost mother-infant bonding as well as breastfeeding to the ultimate benefit of the child’s health. Boosting mother-infant bonding at a critical stage for infant development can modify the long-term health trajectory of the child. This study is done in collaboration with an interdisciplinary team of Mass General researchers and the Mass General Obstetrics Program. Women who plan to deliver at Mass General are being recruited for this study. Clinical Trial

The Maternal Brain: Examining Neural Alterations Following Traumatic Childbirth

As much as a third of women experience a traumatic childbirth and a significant portion can go on to develop PTSD. Nevertheless, research on the underling biological mechanism of this maternal condition that can detect disease biomarkers is completely lacking. Neuroimaging is currently the only technique that provides direct non-invasive access to the living human brain. This NIH funded study is the first of its kind to examine potential changes in the maternal brain associated with traumatic childbirth and the development of PTSD. We use magnetic resonance imaging (MRI) tasks to reveal the core neural abnormalities of childbirth-related PTSD and how these abnormalities can mediate problems in early mother-infant attachment and impair healthy child development. Elucidating the neural correlates of postpartum PTSD and yielding clinically relevant biomarkers could translate into the development of new therapies and improve clinical diagnosis. This study is open for enrollment.

Childbirth-induced Postpartum Psychological Outcomes

Identifying at risk women for postpartum mental health disorders is crucial for implementing preventive treatment tailored to different symptoms. In this large-scale prospective, longitudinal study, we are examining women’s mental health trajectories from pregnancy through childbirth into the early postpartum period. We study the experience of childbirth and subsequent heterogeneous psychological responses to better capture the dynamic nature of postpartum coping over time. We assess negative as well as positive mental health outcomes induced by the childbirth experience and the factors predicting these responses. Women who plan to deliver at Mass General are recruited for this study, which is conducted in collaboration with Mass General Obstetrics Program. To learn more, contact our team at MothersStudy@partners.org.

Traumatic Childbirth: A Physiological Approach to Study Maternal Posttraumatic Stress Disorder

In this study we are examining the validation of maternal PTSD. To this end, we are using the same experimental methods that have been developed to establish the recognition of combat-related PTSD. We ask whether the memory of childbirth can trigger heightened physiological responses, similarly to the well-documented physiological reactivity seen in veterans diagnosed with PTSD. This study may call for expanding the formal DSM definition of postpartum conditions to include disorders of traumatic stress. Clinical Trial

International Study of Childbirth Characteristics and Subsequent PTSD

We recently completed a study of nearly 700 postpartum women from around the globe, targeting posttraumatic stress symptoms following childbirth. We have found that as much as 12% of women are expected to experience PTSD symptoms at a clinical level after giving birth to a healthy baby at term. Women who have an unscheduled Cesarean are three times more likely to suffer from PTSD

Overall, our findings show that objective stressors in birth such as mode of delivery and obstetrical complications as well as the woman’s subjective traumatic experience of childbirth predict the development of subsequent PTSD. Socioeconomic disadvantage also increases vulnerability. Furthermore, having symptoms of PTSD can interfere with the mother’s ability to bond with her baby

How was your childbirth experience?

We at Harvard University and Mass General Hospital are collaborating with other investigators around the globe to improve maternal mental health following childbirth. For this purpose, we would like to learn about your recent childbirth experience.
Let’s work together to collect critical information to ensure that women will receive all the support they deserve around childbirth.

Click here to complete an anonymous survey. It will take about 15 minutes to complete. Please note, this study is only open to those who gave birth at a Harvard-affiliated hospital within the past 6-12 weeks.

Completed Lab Studies

Impact of Coronavirus on Mother’s Birth Experience and Wellbeing

The outbreak of the COVID-19 pandemic turned the lives of millions of people upside down all over the globe and affected our wellbeing. Our mothers wellness coronavirus project was an international study open to all women in the U.S. and other countries. This study yielded a extensive findings that have been published in six journal articles:

  • We found that mothers in COVID-19-exposed communities endorsed more clinically acute stress response to childbirth than matched controls. Acute stress mediated the relationship between study group and postpartum outcomes. (PMID33412491)
  • Nearly 50% of COVID-19-positive women endorsed acute traumatic stress symptoms at a clinical level in response to childbirth. This group was more than twice as likely to endorse acute stress and to have no visitors during maternity hospitalization than COVID negative women. The COVID-19-positive group reported higher levels of pain in delivery, lower newborn weights, and more infant admission to neonatal intensive care units (PMID34188137). 
  • >60% of participants reported childbirth-related post-traumatic growth (PTG), with greater appreciation of life endorsed most frequently. In deliveries during the pandemic, childbirth-related acute stress was linked with elevated PTG; in turn, PTG was associated with lower posttraumatic stress symptoms and better mother-infant bonding. (PMID35772629)
  • We used a machine learning-based natural language processing model to represent childbirth narratives as vectors that served as inputs for a neural network machine learning model to identify participants with childbirth-related posttraumatic stress disorder (CB-PTSD). (PMID36509356)
  • We used numerical vector representations of childbirth narratives and compared ChatGPT vs. other machine learning (ML)-based large language models to assess for CB-PTSD, and we developed a model that performs very well (F1 score: 0.81). (PMID37886525)
  • We demonstrated the feasibility of using the Peritraumatic Distress Inventory (PDI) to assess for acute distress to classify women likely to endorse CB-PTSD. The data used in this study is also related to our International Survey. (PMID38070747)

She earned a Ph.D. in Clinical Psychology from Columbia University and completed her clinical internship training at Columbia Medical Center followed by a research postdoctoral fellowship in a leading international Trauma lab. Dr. Dekel is also a licensed clinical psychologist.

Dr. Dekel has been studying biological and psychological factors associated with ways of coping with stressful events. Her work on the positive outlook of traumatic stress is considered pioneering in the field. Rather than viewing trauma outcomes as exclusively negative, her studies have increased our understanding of the human capacity to thrive in the wake of trauma (see Dr. Dekel’s publication record). 

Since joining Massachusetts General Hospital in 2013, Dr. Dekel has expanded her research with the investigation of childbirth as a potentially traumatic event. This represents a new frontier in trauma studies. She developed a multidisciplinary research model involving both the Mass General Psychiatric and OB/GYN Departments that has allowed her to study over 4,000 postpartum women. Dr. Dekel is defining the overlooked condition of childbirth-related post-traumatic stress disorder (CB-PTSD) and working to better understand the transmission of the disorder’s effects to the offspring. By studying childbirth as a model of traumatic stress, she hopes to translate the knowledge gained to improve clinical care of trauma-exposed individuals. 

Dr. Dekel is a two-time recipient of the Brain and Behavior Research Foundation’s Young Investigator Award, the MGH’s Executive Committee On Research ISF funding, and the Harvard Mind Brain Behavior Faculty Award, as well as having received Mass General’s Claflin Distinguished Scholar Award for Women in Science, and is a recent recipient of Postpartum Support International Susan A.
