Psychosocial Predictors of Postpartum Posttraumatic Stress Disorder in Women With a Traumatic Childbirth Experience

Perineal tear and childbirth-related posttraumatic stress: A prospective cohort study

OBJECTIVE

Quantitative studies examining the occurrence of childbirth-related posttraumatic stress disorder (CB-PTSD) following severe perineal rupture are lacking. The objective of this population-based study was to investigate the prospective associations between the degree of perineal tear during childbirth and CB-PTSD symptoms, when adjusting for known covariates (maternal age, years of school education, premature birth, and parity). We hypothesized that women with different degrees of perineal tear will differ regarding (1) the level of CB-PTSD symptoms at 8 weeks and 2 years postpartum and (2) the rate of change in CB-PTSD symptoms from 8 weeks to 2 years postpartum.

METHOD

Secondary data analysis from the Akershus Birth Cohort, a large population-based prospective cohort study using self-report questionnaires and hospital record data.

RESULTS

The degree of perineal tear was significantly associated with CB-PTSD symptoms at 8 weeks and 2 years postpartum. However, the degree of perineal tear was not significantly associated with the change in CB-PTSD symptoms over time. Similar patterns were found for both total CB-PTSD symptoms as well as for avoidance and intrusion symptoms only.

CONCLUSION

Results seem to support a dose-response model, suggesting that the higher the severity of the perineal tear, the higher the posttraumatic morbidity.

Postpartum acute stress disorder symptoms, social support, and quality of couple's relationship associations with childbirth PTSD

Background

We aimed to examine the hypothesized negative associations between childbirth post-traumatic stress disorder (PTSD) symptoms (using the two-factor model of birth-related and general symptoms), social support, and a couple's relationship quality at 8-12 weeks postpartum. This analysis considered the longitudinal positive shared variance with acute stress disorder (ASD) symptoms measured shortly after birth, while accounting for obstetric and demographic variables.

Methods

Participants included 246 mothers who gave birth at the maternity ward of a tertiary healthcare center. Self-report questionnaires were used 1-4 days postpartum (T1): Demographic information, the Birth Satisfaction Scale-Revised (BSS-R), and the National Stressful Events Survey Acute Stress Disorder Short Scale (NSESSS). At T2 (8-12 weeks postpartum), the Multidimensional Scale of Perceived Social Support (MSPSS), the Dyadic Adjustment Scale (DAS-7), and the City Birth Trauma Scale (BiTS).

Results

In partial support of our hypotheses, three hierarchical regression analyses revealed a significant positive contribution of ASD symptoms to childbirth PTSD general symptoms (β = .33, p <.001) and the total score (β = .29, p <.001), but not to birth-related symptoms. Social support (β = -.21, p = .003) and the quality of the couple's relationship (β=-.20, p = .003) showed negative associations with the BiTS general symptoms.

Conclusion

Our study enhances understanding of the shared variance between childbirth ASD and PTSD, supporting the factor structure of general and birth-related symptoms as different aspects of childbirth PTSD and highlighting the negative association of social support and the quality of a couple's relationship with PTSD general symptoms, suggesting potential avenues for targeted interventions.

The Role of Social Support in Perinatal Mental Health and Psychosocial Stimulation

Social support refers to the help someone receives emotionally or instrumentally from their social network. Poor social support in the perinatal period has been associated with increased risk for symptoms of common mental disorders, including depression and posttraumatic stress symptoms (PTS), which may impact parenting behavior. Whether social support impacts parenting behaviors, independent of mental health symptomatology, remains unclear. Among N=309 participants of the Scaling Up Maternal Mental healthcare by Increasing access to Treatment (SUMMIT Trial), a large perinatal depression and anxiety treatment trial, we explored the relations between perceived social support, perinatal depressive and PTS symptoms, and psychosocial stimulation provided by the parent in their home environment. Social support was measured at baseline using the Multidimensional Scale of Perceived Social Support (MSPSS). Perinatal depressive symptoms were measured by the Edinburgh Postnatal Depression Scale (EPDS) and PTS symptoms were measured by the Abbreviated PTSD Checklist (PCL-6) at baseline, 3-, and 6-months post-randomization. Psychosocial stimulation was assessed by the Home Observation Measurement of the Environment (HOME) when the infant was between 6 to 24 months. Using stepwise hierarchical regressions, we found: (1) perceived social support at baseline significantly predicted both depressive and PTS symptoms at 3-months post-randomization, even when controlling for baseline depressive and PTS symptoms; and (2) while neither depressive nor PTS symptoms were significantly associated with psychosocial stimulation, perceived social support at baseline was a significant predictor. Clinical implications regarding treatment of perinatal patients are discussed.

The Relation between Birth with Cesarean Section and Posttraumatic Stress in Postpartum Women

Objective: The aim of this study was to investigate the relation between cesarean section and postpartum posttraumatic stress disorder as well as the factors that contribute to the development of posttraumatic symptoms in mothers. Materials and methods: A sample of 538 women who gave birth with emergency and elective cesarean section in a University Hospital of Thessaly, Greece, have consented to participate in a two-phase prospective study. A socio-demographic questionnaire, the stressor Criterion A, the Life Events Checklist and the Posttraumatic Checklist of the fifth edition of the Diagnostic and Statistical Manual (DSM-5) were used to diagnose posttraumatic symptoms in Greek postpartum mothers. Results:Out of 538 mothers, 37.2% had an emergency cesarean section and the remaining 62.8% an elective one. Posttraumatic stress was seen in 26 (26%) of women with emergency surgery and three (3%) of those with elective surgery. The present study also found that the inclusion of a neonate to the NICU, complications during pregnancy and delivery, lack of breastfeeding and lack of support from the partner were strongly associated with the development of posttraumatic symptoms. Conclusions:The results of the current study indicate the need to take measures to reduce cesarean section rates and promote vaginal delivery. The high posttraumatic stress rates make it imperative to take additional measures for the mental health of women after cesarean section, especially in those with a traumatic birth experience.

Childbirth-related posttraumatic stress symptoms - examining associations with hair endocannabinoid concentrations during pregnancy and lifetime trauma

Evidence has linked alterations of the endocannabinoid system with trauma exposure and posttraumatic stress disorder (PTSD). Childbirth-related PTSD symptoms (CB-PTSS) affect about every eighth woman and can negatively influence the entire family. While aetiological models of CB-PTSD include psychological risk factors such as maternal trauma history and negative subjective birth experience (SBE), they lack biological risk indicators. We investigated whether lifetime trauma and CB-PTSS were associated with long-term endocannabinoid concentrations during pregnancy. Further, we tested endocannabinoids as mediators between lifetime trauma and CB-PTSS and whether SBE moderated such mediational paths. Within the prospective cohort study DREAMHAIR, 263 expectant mothers completed trauma assessments and provided hair samples for quantification of long-term endocannabinoid levels (anandamide [AEA], 2-arachidonoylglycerol [1-AG/2-AG], and N-acyl-ethanolamides [NAE]) prior to their anticipated birth date. Two months postpartum, CB-PTSS and SBE were measured. Regression models controlling for relevant confounders showed no association between lifetime trauma and hair endocannabinoids during pregnancy, yet higher number of lifetime trauma events and lower hair AEA were significantly associated with CB-PTSS, with the latter finding not remaining significant when Bonferroni corrections due to multiple testing were applied. While hair AEA did not mediate the association between lifetime trauma and CB-PTSS, the effect of lower hair AEA on CB-PTSS was stronger upon negative SBE. Results suggest greater lifetime trauma and reduced maternal hair AEA during pregnancy may be associated with increased risk for CB-PTSS, particularly upon negative SBE. Findings confirm lifetime trauma as a CB-PTSS risk factor and add important preliminary insights on the role of endocannabinoid ligand alterations and SBE in CB-PTSS pathology.

Birth trauma: the elephant in the nursery

METHOD

The current study used a multiperspectival (dyadic) IPA approach to interview eight participants (N = 4 heterosexual couples) where one parent was help-seeking for the experience of birth trauma.

RESULTS

Analysis resulted in four superordinate themes: (1) From perfect plan to shattered reality, (2) Trauma in the healthcare system, (3) Trauma in the family system and (4) The post-trauma family: Navigating the new normal.

DISCUSSION

Parents described a shared experience of birth trauma during birth. However, fathers' perceived trauma ended in the delivery room whilst mothers' continued far beyond this. The dyadic focus showed a divergence of experience postnatally: differing levels of awareness to distress existed between partners, mothers experienced bonding difficulties and parents took to separate coping mechanisms. The trauma remained invisible and unspoken as couples avoided discussions about the birth, coped silently and separately. The parents identity changed following the trauma as individuals, couples and as a family.

CONCLUSION

The time following a traumatic birth is experienced differently by mothers and fathers. Parents seldom discuss the trauma, hold differing perceptions of roles and needs, and struggle to support each postnatally. Clinical implications and recommendations are discussed.

Predictors of pregnancy stress and psychological birth trauma in women undergoing vaginal delivery: a cross-sectional study in China

BACKGROUND

Psychological birth trauma exhibits a high incidence worldwide, resulting in a wide range of negative impacts on mothers, infants, couples, families and society at large through the maternal-centered ripple effect. However, there is currently limited research on psychological birth trauma in China. Social support and pregnancy stress are important influencing factors of psychological birth trauma. Consequently, this study aimed to explore predictors of pregnancy stress and psychological birth trauma in women undergoing vaginal delivery in China.

METHODS

This cross-sectional study was performed at a single medical center between December 2021 and May 2022 in Hangzhou, China. Participants were selected using a convenience sampling technique. A total of 351 postpartum women within one week after vaginal delivery were included. Questionnaires were used to collect sociodemographic and obstetric characteristics and scores on the Pregnancy Stress Rating Scale (PSRS), City Birth Trauma Scale (City BiTS), Social Support Rating Scale (SSRS) and Family Adaptation Partnership Growth Affection and Resolve index (Family APGAR). Both univariate analysis and multiple linear regression analysis were conducted to assess predictors of pregnancy stress and psychological birth trauma.

RESULTS

The median (IQR) of PSRS and City BiTS scores were 10.00 (14.00) and 3.00 (9.00), respectively. The incidence of postpartum posttraumatic stress disorder was 4.0% (14/351). Parity, social support, family support and level of education were predictors of pregnancy stress. Delivery complications, psychological traumatic event, pregnancy stress and family support were predictors of psychological birth trauma (P < 0.05).

CONCLUSION

Pregnancy stress is related to social support, family support and some sociodemographic and obstetric characteristics. Psychological birth trauma is correlated with delivery complications, psychological traumatic event, pregnancy stress and family support. Consequently, enhancing social support, especially family support, for pregnant women as a means of reducing pregnancy stress can effectively prevent psychological birth trauma.

Unmet Parental Mental Health Service Needs in Neonatal Follow-Up Programs: Parent and Service Provider Perspectives

Parental mental health services in neonatal follow-up programs (NFUPs) are lacking though needed. This study aimed to determine (1) the unmet mental health needs of parents and (2) the parent and provider perspectives on barriers and opportunities to increase mental health service access. Study 1: Parents in a central Canadian NFUP (N = 49) completed a mixed-method online survey (analyzed descriptively and by content analysis) to elucidate their mental health, related service use, barriers to service use, and service preferences. Study 2: Virtual focus groups with NFUP service providers (N = 5) were run to inform service improvements (analyzed by reflexive thematic analysis). The results show that parents endorsed a 2-4 times higher prevalence of clinically significant depression (59.2%), anxiety (51.0%), and PTSD (26.5%) than the general postpartum population. Most parents were not using mental health services (55.1%) due to resource insecurity among parents (e.g., time, cost) and the organization (e.g., staffing, training, referrals). Consolidating parents' and service providers' perspectives revealed four opportunities for service improvements: bridging services, mental health screening, online psychoeducation, and peer support. Findings clarify how a central Canadian NFUP can address parental mental health in ways that are desired by parents and feasible for service providers.

Traumatic Childbirth Experience and Childbirth-Related Post-Traumatic Stress Disorder (PTSD): A Contemporary Overview

With this manuscript we provide an overview of the prevalence, symptoms, risk factors, screening, support, and treatment for women with a traumatic childbirth experience or childbirth-related PTSD. This overview is based on both recent literature and the authors' clinical experiences from the fields of obstetrics, psychiatry and medical psychology to provide up-to-date knowledge about recognizing, preventing and treating CB-PTSD from a clinical perspective. We pay substantial attention to prevention as there are many things health care professionals can do or not do to contribute to a positive childbirth experience, and save women, their infants and families from a sub-optimal start due to childbirth-related trauma.

Mother-Child Bond through Feeding: A Prospective Study including Neuroticism, Pregnancy Worries and Post-Traumatic Symptomatology

Post-traumatic stress disorder (PTSD) is a common postpartum problem and influences maternal bonding with the infant. However, the relationship between this disorder, maternal personality, and the infant's emotional state during feeding is not clear. The aim of the present study was to explore the contribution of neuroticism on the infant's emotional state during feeding, by attending to the mediating role of postpartum PTSD (P-PTSD) symptoms and the moderating role of worries during pregnancy. A prospective design study was developed with 120 women with a low pregnancy risk. They responded to a questionnaire assessing maternal personality (first trimester), worries during pregnancy (third trimester), P-PTSD symptoms, and mother-baby bonding (4 months postpartum). The results showed a positive association among neuroticism, infant irritability during feeding, and P-PTSD symptoms, suggesting the latter plays a mediating role in the relationship between neuroticism and infant irritability (B = 0.102, standard error (SE) = 0.03, 95% coefficient interval (CI) [0.038, 0.176]). Excessive worries, related to coping with infant care, played a moderating role between neuroticism and P-PTSD symptoms (B = 0.413, SE = 0.084, p = 0.006, 95% CI [0.245, 0.581]). This relationship was interfered with by depressive symptoms in the first trimester (covariate) (B = 1.820, SE = 0.420, p = 0.016, ci [2.314, 0.251]). This study contributes to a better understanding of the role of neuroticism as an influential factor in the occurrence of P-PTSD symptoms, and in the impairment of infant bonding during feeding. Paying attention to these factors may favor the development of psychological support programs for mothers, with the aim of strengthening the bond with their child.

Effect of Midwife-Provided Orientation of Birth Companions on Maternal Anxiety and Coping during Labor: A Stepped Wedge Cluster Randomized Control Trial in Eastern Uganda

The study aimed to assess the effect of midwife-provided orientation of birth companions on maternal anxiety and coping during labor. A stepped wedge cluster randomized trial design was conducted among 475 participants (control n = 240), intervention n = 235) from four clusters. Midwives in the intervention period provided an orientation session for the birth companions on supportive labor techniques. Coping was assessed throughout labor and anxiety scores were measured after birth. Independent t-test and Chi-Square tests were used to assess the differences by study period. Anxiety scores were reduced among women in the intervention period (p = 0.001). The proportion of women able to cope during early active labor was higher during the intervention period (p = 0.031). Women in the intervention period had 80% higher odds of coping (p = 0.032) compared to those in the control period. Notable differences in anxiety and coping with labor were observed among first-time mothers, younger women, and when siblings provided support. Midwife-provided orientation of birth companions on labor support lowers maternal anxiety and improves coping during labor. Findings could inform the planning and development of policies for the implementation of the presence of birth companions in similar low-resource settings.

Postpartum post-traumatic stress symptoms during the COVID-19 period: exposure and fear as mediating factors

Background: Post-traumatic stress symptoms (PTSS) following childbirth are common within a stressful environment and are mitigated by social support. During the COVID-19 pandemic, an increase in such symptoms has been reported. The current study aims to longitudinally model the influence of general and pandemic-specific risk and protective factors on the temporal unfolding of symptoms among postpartum women.Methods: Participants were 226 women following a liveborn, term birth during the first lockdown in Israel. Participants completed questionnaires 10 weeks (T1) and 6 months (T2) after delivery. PATH analyses included predictors of symptoms in T1: demographics, exposure to traumatic events, medical complications during delivery or pregnancy, exposure to COVID-19-related events and their subjective impact, fear of COVID-19, and social support. Predictors of symptoms in T2 were: T1 predictors, both as direct effects and mediated by T1 PTSS, as well as predictors measured again in T2.Results: Results showed the suggested model fit the data. The effect of COVID-19-related fear and subjective impact at T1 on symptoms at T2 were fully mediated by PTSS in T1, as were the effects of marriage and high social support at T1. COVID-19-related fear at T2 positively predicted symptoms at T2, while social support at T2 had the opposite effect. Medical complications during pregnancy negatively predicted symptoms in T2 only.Discussion: Persistent fear appears to be a risk factor and supports a consistent buffer in postpartum PTSS during the COVID-19 pandemic. Medical complications during pregnancy served as a protective factor, possibly due to habituation to medical settings.

Developing a woman-centered, inclusive definition of traumatic childbirth experiences: A discussion paper

INTRODUCTION

Many women experience giving birth as traumatic. Although women's subjective experiences of trauma are considered the most important, currently there is no clear inclusive definition of a traumatic birth to help guide practice, education, and research.

AIM

To formulate a woman-centered, inclusive definition of a traumatic childbirth experience.

METHODS

After a rapid literature review, a five-step process was undertaken. First, a draft definition was created based on interdisciplinary experts' views. The definition was then discussed and reformulated with input from over 60 multidisciplinary clinicians and researchers during a perinatal mental health and birth trauma research meeting in Europe. A revised definition was then shared with consumer groups in eight countries to confirm its face validity and adjusted based on their feedback.

RESULTS

The stepwise process confirmed that a woman-centered and inclusive definition was important. The final definition was: "A traumatic childbirth experience refers to a woman's experience of interactions and/or events directly related to childbirth that caused overwhelming distressing emotions and reactions; leading to short and/ or long-term negative impacts on a woman's health and wellbeing."

CONCLUSIONS

This definition of a traumatic childbirth experience was developed through consultations with experts and consumer groups. The definition acknowledges that low-quality provider interactions and obstetric violence can traumatize individuals during childbirth. The women-centered and inclusive focus could help women to identify and validate their experiences of traumatic birth, offering benefits for practice, education, and research, as well as for policymaking and activism in the fields of perinatal mental health and respectful maternity care.

The Involvement of Past Traumatic Life Events in the Development of Postpartum PTSD after Cesarean Delivery

BACKGROUND

Although childbirth is considered a natural process, a high percentage of postpartum women consider it traumatic. Any previous traumatic event in a woman's life can be revived through a traumatic birth experience, especially after a complicated vaginal delivery or cesarean delivery. The purpose of this study was to clarify the relationship between previous traumatic life events and posttraumatic stress disorder (PTSD) in postpartum women after cesarean section and which specific events exerted the greatest influence.

METHODS

A sample of 469 women who had undergone cesarean sections at a Greek university hospital consented to participate in this prospective study. Data from a medical/demographic questionnaire, life events checklist, perinatal stressor criterion A, and posttraumatic stress checklist were used to evaluate past traumatic life events and diagnose postpartum posttraumatic stress.

RESULTS

Out of 469 women, 25.97% had PTSD and 11.5% a PTSD profile, while 2.7% had PTSD and 2.7% a PTSD profile. Also, it appeared that only specific direct exposure to a traumatic event and/or witnessing one were predictors of postpartum PTSD.

CONCLUSIONS

This survey identified specific traumatic life events, psychiatric history, stressor perinatal criterion A, preterm birth, and emergency cesarean section as risk factors for the development of PTSD or a PTSD profile in women after cesarean delivery.

Ensuring Trauma Informed Care in the Obstetric Setting: A vital role for the Psychiatrist

BACKGROUND

Trauma is highly prevalent, and women are twice as likely as men to develop post-traumatic stress disorder following a traumatic exposure. Consequently, many women entering the perinatal period have trauma histories. In the perinatal period, a trauma history, can negatively impact treatment engagement and adversely affect the experience of pregnancy, postpartum and parenting. A trauma informed care approach can mitigate these effects.

OBJECTIVES

This review aims to summarize literature that can aid psychiatrists in 1) identifying signs and symptoms of trauma in perinatal women 2) integrating elements of trauma informed care into perinatal mental health care, and 3) offering interventions that can minimize adverse outcomes for perinatal women and their children.

METHODS

A PubMed search was conducted with keywords including trauma, pregnancy, perinatal, post-traumatic stress disorder (PTSD), postpartum PTSD, trauma informed care.

RESULTS

Perinatal care, given its somewhat invasive nature, has the potential to traumatize or cause re-traumatization. Trauma related disorders are common and can present or worsen in the perinatal period. Trauma can manifest in multiple forms in this population, including exacerbation of pre-existing PTSD, new onset acute stress disorder in the perinatal period or postpartum PTSD secondary to traumatic childbirth. Unaddressed trauma can adversely affect the experience of pregnancy, postpartum and parenting. Psychiatrists caring for women in the perinatal period, are in an ideal position to screen for trauma and offer appropriate intervention. A trauma informed approach to obstetric care can help clinical teams respond to the unique trauma-related challenges that can arise during obstetric care. Trauma informed care, with its emphasis on establishing a culture of safety, transparency, trustworthiness, collaboration, and mutuality can empower health care providers and systems with powerful tools to respond to trauma and its myriad effects in a strengths-based manner. By applying a trauma-informed lens, psychiatrists can help their obstetric colleagues provide patient-centered compassionate care and treatment.

CONCLUSIONS

Applying a trauma informed approach to evaluation and treatment of perinatal populations could decrease the toll trauma has on affected women and their children.

Association among postpartum posttraumatic stress disorder, family coping, neurodevelopment, and language development in high-risk infants: a retrospective study

BACKGROUND

A high-risk infant (HRI) is a child whose fetal, neonatal, and infant development is impacted by adverse factors that may cause cognitive, sensory, behavioral, or language defects. The complex situation in the treatment process is a continuous challenge and stressor for parents. If parents fail to take appropriate coping styles, it will have an adverse impact on the health of parents and the growth and development of children. The purpose of this study was to explore the impact of clinical characteristics, postpartum posttraumatic stress disorder (PTSD), and family coping on the neurodevelopment and language development of HRIs as a reference for targeted intervention.

METHODS

This study retrospectively recruited 211 children who were hospitalized in the neonatal intensive care unit (NICU) of Suzhou Kowloon Hospital from January 2018 to December 2021. HRI and their mother were interviewed by telephone with general information questionnaire, Perinatal Post-traumatic Stress Disorder Questionnaire, medical coping modes questionnaire, Bayley Scales of Infant Development the Early Language Milestone Scale to investigate HRI and their mothers; Logistic regression was used to analyze the relationship between HRI mothers' emotions and family coping with neurodevelopment and language development.

RESULTS

The neurodevelopmental scores of HRIs differed according to gestational week of delivery, birth weight, and disease diagnosis. The language development scores of HRIs differed according to gestational week of delivery, birth weight, disease diagnosis, and maternal education. Multiple stepwise regression analysis showed that the neurodevelopmental scores were affected by gestational week of delivery, postpartum PTSD score, and family coping. Logistic regression analysis showed that the language development scores were affected by maternal education and neurodevelopmental level. The correlation analysis showed that the postpartum PTSD scores were negatively correlated with family coping, neurodevelopment, and language development, and that family coping was positively correlated with the neurodevelopment and language development scores (P<0.05).

CONCLUSIONS

The neurodevelopment and language development of HRIs were affected by the gestational week of delivery, maternal education, the child's birth weight, and disease diagnosis. NICU wards can promote the healthy development of HRIs by providing mothers with targeted health education concerning the child's condition, postpartum PTSD, and family coping strategies.

An Association Between Psychological Childbirth Trauma and Hazardous Alcohol Use

Hazardous alcohol use is increasing amongst some groups of women, yet little is known about the underlying reasons or gender-specific influences. The purpose of this study was to explore the association between psychological childbirth trauma and women’s hazardous alcohol use. We aimed to identify predictors of hazardous alcohol use given childbirth-related trauma, other life trauma (combat, natural disasters, physical or sexual assault, experiences threatening loss of life or loss of loved ones) and coping motives for drinking, whilst controlling for age, socio-economic status, negative affect and other drinking motives (enhancement and social motives). Australian data from the Why Women Drink survey (N = 301) was analysed. Women who experienced childbirth as traumatic scored higher overall for hazardous drinking and endorsed coping reasons more strongly than those who did not. Analyses of individual differences affecting hazardous drinking revealed coping reasons, rather than trauma itself, as the strongest predictor in a regression model. Other significant predictors included socio-economic status, enhancement of positive emotions and, marginally, negative affect. Findings identified a link between traumatic childbirth and hazardous drinking as a coping strategy. Prospective research is required to characterise predisposing and perpetuating vulnerabilities determining maladaptive coping after traumatic childbirth, and to inform effective interventions.

The Important Role of Partner Support in Women's Mental Disorders During the Perinatal Period. A Literature Review

The arrival of a newborn is often a happy event in a woman's life. However, many women experience perinatal distress such as anxiety disorders and depression during pregnancy or postpartum period. Although the positive interpersonal relationships of women with their wider environment seem to be a support network, research shows that support provided by partners is a very important protective factor in reducing mental health disorders in both prenatal and postnatal period in a woman's life. for this reason, more research needs to be done in the field of perinatal distress in order to clarify the causes that lead to mental disorders and to strengthen the partner's role in the management of perinatal mental disorders of women.

Smoking Patterns and Anxiety Factors Among Women Expressing Perinatal Depression

Background: Relationships among perinatal depression occurring a number of weeks before and after childbirth and smoking have been identified. Depression may lead to the inability to abstain from smoking during pregnancy.

Objectives: This study aims to determine factors affecting smoking during pregnancy revealing potential relationships between depression and smoking patterns during and after pregnancy.

Methods: A total of 206 mothers participated in the study. Data were collected through self-reporting as respondents were asked to answer questionnaires during the 12th week of pregnancy, during the 30th week of pregnancy, after childbirth, and during the period after pregnancy. Relationships between smoking behavior, sociodemographic variables, and feelings of perinatal depression were examined using chi-square test and binary logistic regression analysis. A follow-up investigation has been conducted after 2 years revealing the percentage of women returning to their smoking habits.

Results: Smokers before (B = 0.568; p = 0.026) and during pregnancy (B = 1.238; p = 0.009) were more likely to express depression before childbirth. Average daily cigarette consumption before (B = 1.110; p = 0.001) and during pregnancy (B = 1.167; p = 0.002) was associated with depression during pregnancy. Women who smoked during pregnancy reported significantly more depressive symptoms after pregnancy (B = 1.757; p = 0.005) compared with nonsmokers and smokers who abstained during pregnancy. Average daily cigarette consumption during pregnancy (B = 1.402; p = 0.002) affects the expression of depression after pregnancy. Women who smoked before pregnancy (B = 0.568; p = 0.025) and their average daily cigarette consumption before pregnancy (B = 1.465; p = 0.025) were highly associated with the inability to abstain from smoking during pregnancy. However, the knowledge of risks of maternal smoking during pregnancy (B = −1.110; p = 0.001) and medical consult on abstaining (B = −1.238; p = 0.009) reinforced the maternal attempt to quit smoking. The follow-up investigation revealed an elevated amount of women returning to previous smoking patterns.

Discussion: Perinatal depression is associated with smoking patterns during pregnancy. Assessment of depression and smoking is needed throughout perinatal period to support the health of women.

The association between caesarean and postnatal psychological distress: Effect modification by mental health history

BACKGROUND

The association between mode of delivery and postnatal depression is uncertain. Mental health history may modify the association.

OBJECTIVES

The objective of this study was to determine whether the association between caesarean and postnatal psychological distress (PPD) differs according to long-standing depression/anxiety.

METHODS

Analysis of the UK-based Millennium Cohort Study of women who gave birth 2000-2002 was carried out. The outcomes were PPD at 9 months by Rutter Malaise Inventory and actively treated physician-diagnosed depression/severe anxiety at 3 years. The exposure was mode of delivery. Adjusted relative risks were estimated using Poisson regression. Effect modification according to long-standing depression/anxiety was investigated multiplicatively and additively.

RESULTS

We included 15,936 women, of whom 2346 (13.4%, weighted) reported PPD. Women with long-standing depression/anxiety were at 34% lower risk of PPD following elective caesarean, compared with vaginal birth: relative risk (RR) 4.36 (95% confidence interval [CI] 3.76, 5.05), RR 3.25 (95% CI 2.23, 4.75) and RR 4.92 (95% CI 3.67, 6.59) for vaginal, elective and emergency caesarean births, respectively, with relative excess risk due to interaction (RERI) -1.28 (95% CI -2.73, 0.16), ratio of RRs 0.66 (95% CI 0.42, 1.05). Women with long-standing depression/anxiety were at greatest risk of later treatment following emergency caesarean, with RR 4.95 (95% CI 3.86, 6.34), RR 4.09 (95% CI 2.51, 6.65) and RR 6.74 (95% CI 4.87, 9.32), for vaginal, elective and emergency caesarean births, respectively; RERI 1.79 (95% CI -0.13, 3.71), ratio of RRs 1.36 (95% CI 0.94, 1.99); all RRs with reference to vaginal birth in the absence of long-standing depression/anxiety. There was no evidence of a similar association between emergency caesarean and PPD nor elective caesarean and later treatment.

CONCLUSIONS

Women with long-standing depression or anxiety who had elective caesarean had a lower risk of postnatal distress. When this group had emergency caesarean, there was greater risk of actively treated depression/anxiety at 3 years. These associations were not observed in women without long-standing depression/anxiety.

Maternal Mental Health Disorders Following Very Preterm Birth at 5 Years Post-Birth

OBJECTIVE

Mothers of children born very preterm (VP) are at increased risk of developing postnatal depression, anxiety, and post-traumatic stress symptoms. However, mental health disorder rates are rarely assessed in this population compared with full-term peers, and it is unclear if postnatal distress symptoms precede higher rates of maternal mental health disorders at 5 years post-birth in both birth groups.

METHODS

Mothers of children born VP (n = 65; mean [SD] age at birth, 33.9 [5.0]; 72.1% tertiary educated) and full-term (n = 90; mean [SD] age at birth, 33.4 [4.0]; 88.2% tertiary educated) completed questionnaires assessing symptoms of depression, anxiety, and trauma within 4 weeks of birth. At 5 years post-birth, they participated in a structured diagnostic interview assessing mood, anxiety, and trauma-related mental health disorders, both current and over the lifetime.

RESULTS

There was little evidence for differences between mothers in the VP and full-term groups in rates of any mental health disorder at 5 years (VP = 14%, full-term = 14%) or lifetime (VP = 41%, full-term = 37%). In mothers of children born VP, elevated postnatal post-traumatic stress symptoms were associated with higher rates of mental health disorders at 5 years (odds ratio = 21.5, 95% confidence interval = 1.35-342).

CONCLUSIONS

Findings suggest that preterm birth may not lead to increased odds of later developing maternal mental health disorders, despite known risks of elevated postnatal distress following a VP birth. However, those with post-traumatic stress symptoms following a VP birth could be more vulnerable, and assessment and monitoring is recommended.

The Lausanne Infant Crying Stress Paradigm: Validation of an Early Postpartum Stress Paradigm with Women at Low vs. High Risk of Childbirth-Related Posttraumatic Stress Disorder

Stress reactivity is typically investigated in laboratory settings, which is inadequate for mothers in maternity settings. This study aimed at validating the Lausanne Infant Crying Stress Paradigm (LICSP) as a new psychosocial stress paradigm eliciting psychophysiological stress reactivity in early postpartum mothers (n = 52) and to compare stress reactivity in women at low (n = 28) vs. high risk (n = 24) of childbirth-related posttraumatic stress disorder (CB-PTSD). Stress reactivity was assessed at pre-, peri-, and post-stress levels through salivary cortisol, heart rate variability (high-frequency (HF) power, low-frequency (LF) power, and LF/HF ratio), and perceived stress via a visual analog scale. Significant time effects were observed for all stress reactivity outcomes in the total sample (all p < 0.01). When adjusting for perceived life threat for the infant during childbirth, high-risk mothers reported higher perceived stress (p < 0.001, d = 0.91) and had lower salivary cortisol release (p = 0.023, d = 0.53), lower LF/HF ratio (p < 0.001, d = 0.93), and marginally higher HF power (p = 0.07, d = 0.53) than low-risk women. In conclusion, the LICSP induces subjective stress and autonomic nervous system (ANS) reactivity in maternity settings. High-risk mothers showed higher perceived stress and altered ANS and hypothalamic-pituitary-adrenal reactivity when adjusting for infant life threat. Ultimately, the LICSP could stimulate (CB-)PTSD research.

Factors Associated with Postpartum Post-Traumatic Stress Disorder (PTSD) Following Obstetric Violence: A Cross-Sectional Study

To determine the association between experiencing obstetric violence and the incidence of postpartum post-traumatic stress disorder (PTSD). A cross-sectional study with puerperal women was conducted in Spain following ethical approval. The Perinatal Posttraumatic Stress Disorder Questionnaire (PPQ) was administered online. Sociodemographic, clinical, and obstetric violence variables and the risk of dichotomized PTSD (low/high) were studied by bivariate and multivariate analysis with binary logistic regression. 955 women were invited to participate. 53 women refused to participate, three did not complete all survey questions and, finally, 899 women were included. The risk of PTSD (score ≥ 19) using the PPQ was 12.7% (114). The mean score was 9.10 points (SD = 8.52). Risk factors identified were having a delivery plan that was not respected (aOR: 2.85, 95% CI 1.56–5.21), elective caesarean delivery (aOR: 2.53, 95% CI 1.02–2.26), emergency caesarean section (aOR: 3.58, 95% CI 1.83–6.99), admission of the newborn to the neonatal intermediate care unit (aOR: 4.95, 95% CI 2.36–10.36), admission to the intensive care unit (aOR: 2.25, 95% CI 1.02–4.97), formula feeding on discharge (aOR: 3.57, 95% CI 1.32–9.62), verbal obstetric violence (aOR: 5.07, 95% CI 2.98–8.63), and psycho-affective obstetric violence (aOR: 2.61, 95% CI 1.45–4.67). Various clinical practices were identified with the risk of PTSD, highlighting various types of obstetric violence. Partner support and early breastfeeding were identified as protective factors. Sensitizing professionals is essential to prevent the risk of PTSD.

Long-Term High Risk of Postpartum Post-Traumatic Stress Disorder (PTSD) and Associated Factors

Postpartum post-traumatic stress disorder (PTSD) is not a specific process but can last for months and may manifest itself during any subsequent pregnancies or even become chronic. This study aimed to determine the factors associated with long-term PTSD symptoms one year after delivery. A cross-sectional study was conducted on 1301 Spanish puerperal women. Data were collected on sociodemographic, obstetric, and neonatal variables. The Perinatal Post-Traumatic Stress Disorder Questionnaire (PPQ) was administered online through midwives' associations across Spain. Crude odds ratio (OR) and adjusted odds ratio (aOR) and their 95% confidence intervals were calculated. A PPQ score ≥ 19 (high-risk) was recorded for 13.1% (171) of the participants. Identified risk factors were not respecting a birth plan (aOR = 1.89 (95% CI 1.21-2.94)), formula-feeding of the baby at discharge (aOR = 2.50 (95% CI 1.20-5.17)), postpartum surgical intervention (aOR = 2.23 (95% CI 1.02-4.85)), hospital readmission (aOR = 3.45 (95% CI 1.21-9.84)), as well as verbal obstetric violence (aOR = 3.73 (95% CI 2.52-5.53)) and psycho-affective obstetric violence (aOR = 3.98 (95% CI 2.48-6.39)). During childbirth, some clinical practices, such as formula-feeding of the newborn at discharge or types of obstetric violence towards the mother, were associated with a higher risk of PTSD symptoms one year after delivery.

Treatment of Pregnant Women With Fear of Childbirth Using EMDR Therapy: Results of a Multi-Center Randomized Controlled Trial

Fear of childbirth (FoC) occurs in 7. 5% of pregnant women and has been associated with adverse feto-maternal outcomes. Eye Movement Desensitization and Reprocessing (EMDR) therapy has proven to be effective in the treatment of posttraumatic stress disorder (PTSD) and anxiety; however, its effectiveness regarding FoC has not yet been established. The aim was to determine the safety and effectiveness of EMDR therapy for pregnant women with FoC. This single-blind RCT (the OptiMUM-study, www.trialregister.nl, NTR5122) was conducted in the Netherlands. FoC was defined as a score ≥85 on the Wijma Delivery Expectations Questionnaire (WDEQ-A). Pregnant women with FoC and a gestational age between 8 and 20 weeks were randomly assigned to EMDR therapy or care-as-usual (CAU). The severity of FoC was assessed using the WDEQ-A. Safety was indexed as worsening of FoC symptoms, dropout, serious adverse events, or increased suicide risk. We used linear mixed model analyses to compare groups. A total of 141 women were randomized (EMDR n = 70; CAU n = 71). No differences between groups were found regarding safety. Both groups showed a very large (EMDR d = 1.36) or large (CAU d = 0.89) reduction of FoC symptoms with a mean decrease of 25.6 (EMDR) and 17.4 (CAU) points in WDEQ-A sum score. No significant difference between both groups was found (p = 0.83). At posttreatment, 72.4% (EMDR) vs. 59.6% (CAU) no longer met the criteria for FoC. In conclusion, the results are supportive of EMDR therapy as a safe and effective treatment of FoC during pregnancy, albeit without significant beneficial effects of EMDR therapy over and above those of CAU. Therefore, the current study results do not justify implementation of EMDR therapy as an additional treatment in this particular setting.

Elaboration and Validation of Two Predictive Models of Postpartum Traumatic Stress Disorder Risk Formed by Variables Related to the Birth Process: A Retrospective Cohort Study

This study aimed to develop and validate two predictive models of postpartum post-traumatic stress disorder (PTSD) risk using a retrospective cohort study of women who gave birth between 2018 and 2019 in Spain. The predictive models were developed using a referral cohort of 1752 women (2/3) and were validated on a cohort of 875 women (1/3). The predictive factors in model A were delivery type, skin-to-skin contact, admission of newborn to care unit, presence of a severe tear, type of infant feeding at discharge, postpartum hospital readmission. The area under curve (AUC) of the receiver operating characteristic (ROC) in the referral cohort was 0.70 (95% CI: 0.67–0.74), while in the validation cohort, it was 0.69 (95% CI: 0.63–0.75). The predictive factors in model B were delivery type, admission of newborn to care unit, type of infant feeding at discharge, postpartum hospital readmission, partner support, and the perception of adequate respect from health professionals. The predictive capacity of model B in both the referral cohort and the validation cohort was superior to model A with an AUC-ROC of 0.82 (95% CI: 0.79–0.85) and 0.83 (95% CI: 0.78–0.87), respectively. A predictive model (model B) formed by clinical variables and the perception of partner support and appropriate treatment by health professionals had a good predictive capacity in both the referral and validation cohorts. This model is preferred over the model (model A) that was formed exclusively by clinical variables.

Predicting postpartum post-traumatic stress and depressive symptoms in low-risk women from distal and proximal factors: a biopsychosocial prospective study using structural equation modeling

PURPOSE

Posttraumatic stress (PTSD) and depression (PPD) are common mental disorders in the postpartum that constitute a threat both to the mother and the baby. It is unclear whether both disorders share similar antecedents, which is important to plan efficient interventions. The goal of this study was to examine the contribution of set of biopsychosocial predictors on both PTSD and PPD.

METHODS

The study design was prospective. The study was conducted at Hospital Universitario de Fuenlabrada, a public university hospital located in the south of Madrid (Spain). The sample was composed of 116 pregnant women with low pregnancy risk. STROBE reporting guidelines were followed.

RESULTS

The multivariate results show that psychopathology severity assessed during the first trimester (ß = 0.50, p < .001) and the Apgar score 5 min after delivery (ß = - 0.19, p = .030) were the two variables to significantly contribute to postpartum depressive symptoms. Conversely, only satisfaction with home care after delivery was independently associated with postpartum posttraumatic stress (ß = - 0.26, p = .016). The proposed model explained 21.8% of the variance of postpartum depressive symptoms (p = .041) and 27.1% of the variance of posttraumatic stress symptoms (p = .014).

CONCLUSION

Special attention should be given to shared and unique predictive factors of PDD and PTSD to develop effective prevention programs in perinatal care.

Sense of Coherence Mediates the Links between Job Status Prior to Birth and Postpartum Depression: A Structured Equation Modeling Approach

Postpartum depression (PPD) has detrimental effects on the health of the mother, child and family. Socio-demographic variables can influence PPD. Sense of coherence (SOC) is a personal resource that mitigates the experience of stressful events. We hypothesized that SOC would have a protective effect against PPD over time. The aim was to investigate the effects of socio-demographic factors and SOC on PPD at birth (T1) and nine months postpartum (T2). A longitudinal study of primiparous women (n = 114; age range 18-47 years) measured PPD, SOC and socio-demographics at T1 and T2. The majority were married, had no economic difficulties and were employed before birth. Results showed that PPD at T1 (15.8%) declined to 6.2% (T2). Job status was positively associated with SOC at T1. The structured equation model accounted for 27% of the variance in PPD (T2). In the first pathway, job status was linked to PPD (T2) via SOC at T1 and T2. In the second, SOC and PPD (T1) and SOC (T2) mediated the link between job status and PPD (T2). Results and clinical implications are discussed in the context of the theory of conservation of resources. An intervention for enhancing SOC is recommended for woman at risk of PPD.

The oxytocinergic system in PTSD following traumatic childbirth: endogenous and exogenous oxytocin in the peripartum period

Birth experiences can be traumatic and may give rise to PTSD following childbirth (PTSD-FC). Peripartum neurobiological alterations in the oxytocinergic system are highly relevant for postpartum maternal behavioral and affective adaptions like bonding and lactation but are also implicated in the response to traumatic events. Animal models demonstrated that peripartum stress impairs beneficial maternal postpartum behavior. Early postpartum activation of the oxytocinergic system may, however, reverse these effects and thereby prevent adverse long-term consequences for both mother and infant. In this narrative review, we discuss the impact of trauma and PTSD-FC on normal endogenous oxytocinergic system fluctuations in the peripartum period. We also specifically focus on the potential of exogenous oxytocin (OT) to prevent and treat PTSD-FC. No trials of exogenous OT after traumatic childbirth and PTSD-FC were available. Evidence from non-obstetric PTSD samples and from postpartum healthy or depressed samples implies restorative functional neuroanatomic and psychological effects of exogenous OT such as improved PTSD symptoms and better mother-to-infant bonding, decreased limbic activation, and restored responsiveness in dopaminergic reward regions. Adverse effects of intranasal OT on mood and the increased fear processing and reduced top-down control over amygdala activation in women with acute trauma exposure or postpartum depression, however, warrant cautionary use of intranasal OT. Observational and experimental studies into the role of the endogenous and exogenous oxytocinergic system in PTSD-FC are needed and should explore individual and situational circumstances, including level of acute distress, intrapartum exogenous OT exposure, or history of childhood trauma.

Posttraumatic Stress Disorder Postpartum of a Woman Recovered from Drug Addiction: A Case Report

There is high degree of prevalence and variety of risk factors of postpartum Posttraumatic Stress Disorder (PTSD). However, some postpartum women seem to struggle with their past traumatic life events and previous PTSD can result in them sinking deeper into a new PTSD, a postpartum PTSD. The person who has undergone detoxification has endured a very painful process and there is a strong association between drug addiction and mortality. The aim of this case report study is to raise the understanding of health professionals regarding the impact that these two factors might have on ex-drug addicted women. Data were collected from the Maternity unit of the University Hospital of Larisa in Greece. A mother on day 2 after elective cesarean section confirmed her participation and filled in a Life Events Checklist (LEC-5), Posttraumatic Checklist (PCL-5), Criteria A, and a socio-demographic questionnaire. After the sixth postpartum week, the woman answered via telephone, adapted for postpartum PCL-5. This case study describes vividly and painfully the impact of past drug addiction not only on her cesarean section but also how it affected her postpartum period. Eight past traumatic life events led to the creation of a chronic PTSD, i.e., trauma re-experiencing, avoidance, negative thoughts and feelings, agitation, and reactivity. Unfortunately, in cases of traumatic childbirth, especially cesarean section, when there are past traumatic experiences, such as addiction or sexual abuse, postpartum PTSD is an unbearable experience.

Correlation between Kind of Cesarean Section and Posttraumatic Stress Disorder in Greek Women

A birth experience with cesarean section (CS) can be a cause of the development of post-traumatic stress disorder after a cesarean (PTSD-AC) or profile PTSD, for a percentage of women. So far, there is no data on the frequency of PTSD-AC in Greece and this syndrome is often associated with other mental disorders of the postpartum period. The purpose of this research is to associate the kind of CS with PTSD-AC for Greek mothers and the combination of factors that make them less resistant to trauma. A sample of ahundred and sixty-six mothers who gave birth with emergency cesarean section (EMCS) and elective cesarean section (ELCS) at a Greek University hospital have consented to participate in the two phases of the survey, in the 2nd day postpartum and a follow-up in the 6th week postpartum. Medical/demographic data and a life events checklist (LEC-5) with Criterion A and post-traumatic stress checklist (PCL-5) were used to diagnose PTSD and PTSD Profile. Out of166 mothers enrolled, 160 replied to the follow-up (96.4%), ELCS 97 (97%) and EMCS 63 (95%). Twenty (31.7%) EMCS had PTSD and nine (14.3%) had Profile. One (1%) ELCS had PTSD and 4 (4.1%) had Profile. This survey shows a high prevalence rate of PTSD after EMCS with additional risk factors of preterm labor, inclusion in the Neonatal Intensive Care Unit (NICU), a lack of breastfeeding, and a lack of support from the partner.

Delivery mode is associated with maternal mental health following childbirth

Childbirth is a life-transforming event often followed by a time of heightened psychological vulnerability in the mother. There is a growing recognition of the importance of obstetrics aspects in maternal well-being with the way of labor potentially influencing psychological adjustment following parturition or failure thereof. Empirical scrutiny on the association between mode of delivery and postpartum well-being remains limited. We studied 685 women who were on average 3 months following childbirth and collected information concerning mode of delivery and pre- and postpartum mental health. Analysis of variance revealed that women who had cesarean section or vaginal instrumental delivery had higher somatization, obsessive compulsive, depression, and anxiety symptom levels than those who had natural or vaginal delivery as well as overall general distress, controlling for premorbid mental health, maternal age, education, primiparity, and medical complication in newborn. Women who underwent unplanned cesarean also had higher levels of childbirth-related PTSD symptoms excluding those with vaginal instrumental. The risk for endorsing psychiatric symptoms reflecting clinically relevant cases increased by twofold following unplanned cesarean and was threefold for probable childbirth-related PTSD. Maternal well-being following childbirth is associated with the experienced mode of delivery. Increasing awareness in routine care of the implications of operative delivery and obstetric interventions in delivery on a woman's mental health is needed. Screening at-risk women could improve the quality of care and prevent enduring symptoms. Research is warranted on the psychological and biological factors implicated in the mode of delivery and their role in postpartum adjustment.

Synthesis of Mixed Research on Posttraumatic Stress Related to Traumatic Birth

OBJECTIVE

To synthesize mixed-research results (quantitative and qualitative) on posttraumatic stress in women who experienced traumatic births.

DATA SOURCES

PubMed, Scopus, and PsycINFO databases.

STUDY SELECTION

Quantitative and qualitative studies were included if they were published in English from January 1, 2009, through December 31, 2018, and focused on posttraumatic stress in the postpartum period related to traumatic childbirth.

DATA EXTRACTION

The final sample consisted of 59 studies: 4 qualitative and 55 quantitative. Both authors independently appraised each study using the Critical Appraisal Skills Programme. Quantitative studies were synthesized by narrative synthesis and vote counting, and qualitative studies were synthesized by content analysis.

DATA SYNTHESIS

In the included studies, prevalence rates of elevated posttraumatic stress ranged from 0.8% to 26%. Significant predictors of posttraumatic stress that occurred before childbirth and those that were birth related were identified. Reports of six intervention studies to decrease posttraumatic stress symptoms after traumatic births were included. These interventions focused on postnatal debriefing, expressive writing, online cognitive behavioral therapy, a brief cognitive intervention, and the implementation of the nine instinctive stages of the infant during the first hour after birth. We created four themes from the findings of the qualitative studies: Distressing Symptoms, Detrimental Effect of Posttraumatic Stress on Women's Relationships With Their Infants and Partners, Critical Influence ofSupport, and Debriefing.

CONCLUSION

When a woman experiences posttraumatic stress related to a traumatic birth, the entire family unit is vulnerable. Findings from quantitative predictor studies can be used to develop an instrument to screen women for risk factors for posttraumatic stress related to birth trauma. Primary interventions are needed to prevent women from experiencing traumatic births.

Fear and Anxiety Disorders Related to Childbirth: Epidemiological and Therapeutic Issues

PURPOSE OF REVIEW

This paper seeks to identify the risk factors of fear of childbirth (FOC) and posttraumatic stress disorder (PTSD) related to birth and reviews the efficacy of their respective screening tools and therapeutic interventions.

RECENT FINDINGS

Biofeedback, hypnosis, internet-based cognitive behavioral therapy, and antenatal education are promising treatments for FOC. Training midwives to address traumatic birth experiences could help in preventing PTSD. A shorter more pragmatic screening tool for FOC than the Wijma Delivery Expectancy/Experience Questionnaire (WDEQ) is needed. Women with PTSD attributed a mismatch between the expected mode of delivery (MOD) and the actual MOD as the cause of their trauma. A history of mental health disorders, lack of social support, previous negative birth experiences, and MOD are correlated to FOC and postpartum PTSD. Psycho-education and CBT-based treatments have been found to reduce levels of FOC and PTSD.
