A diagnostic questionnaire for childbirth related posttraumatic stress disorder: a validation study

Evaluating a midwife-led consultation for women after a traumatic birth experience: Preliminary results

BACKGROUND

Approximately 9 to 50 % of women report a traumatic birth experience and 12 % develop childbirth-related posttraumatic stress disorder symptoms (CB-PTSS). A recent study using a postpartum midwifery-led counselling session showed promising results in reducing CB-PTSS, but more evidence is needed.

OBJECTIVES

The main objective of the study was to evaluate the impact of a midwifery-led counselling session 6 weeks post-partum or later, on depression and CB-PTSS.

STUDY DESIGN

The pre-post-intervention study, including 159 women, took place in a Swiss 18 university hospital. It was designed as a healthcare service quality project and therefore was therefore not registered a priori in a clinical trial registry. Ethical approval from the institutional board was obtained (n° 2020-06). A midwifery-led counselling session, six weeks or more after birth, allowed women to discuss their childbirth experience and to receive additional information about childbirth. Women completed the Edinburgh Postnatal Depression Scale (EPDS) and the PTSD Checklist for DSM-5 (PCL-5) two weeks before and three months after the consultation.

RESULTS

Results showed a significant decrease in depression and CB-PTSS, and in cases with probable childbirth-related posttraumatic stress disorder diagnosis (CB-PTSD): 24.7 % (36/146) before counselling versus 6.3 % (5/80) three months after (p < 0.01). The session was rated as extremely/very satisfactory by 91 % of women and extremely/very useful by >87 % of women. No associations were found between depression and CB-PTSD scores and obstetrical or neonatal data.

CONCLUSION

A midwifery-led single-session offered to women 6 weeks or more after birth seemed to be associated with a decrease of depression and CB-PTSS. However, the attrition rate (49 %) made definitive conclusions difficult. More research is needed with a larger sample, a randomized design, and a wait-list control group to consider the effect of time on depression or CB-PTSS.

Cognitive behavioural therapy for intolerance of uncertainty: A study protocol for the prevention of postpartum anxiety

BACKGROUND

Mental health disorders are the most prevalent health complication experienced during pregnancy and the postpartum, with anxiety disorders being most common. Intolerance of uncertainty (IU) is a well-known feature of anxiety disorders and has recently been identified as a risk factor for the worsening of anxiety during the postpartum period. Cognitive Behavioural Therapy (CBT) is a first-line treatment for perinatal anxiety, and CBT specifically targeting IU in non-perinatal populations has demonstrated positive findings for reducing anxiety. As such, the objective of our study is to examine whether CBT targeting IU in pregnancy can reduce the risk of postpartum anxiety.

METHODS

This protocol paper outlines a proof-of-concept randomised clinical trial assessing the effectiveness of a newly developed CBT for IU (CBT-IU) protocol to reduce the risk of postpartum anxiety. Pregnant individuals identified at increased risk for postpartum anxiety (defined as a baseline score of 64 or greater on the Intolerance of Uncertainty Scale) will be randomised to receive CBT-IU or care as usual (CAU) during pregnancy and will be followed through the postpartum period (6-12 weeks). The CBT-IU protocol is a weekly, six session treatment, which includes psychoeducation, behavioural experiments, imaginal exposure, and problem-solving to target IU.

DISCUSSION

To our knowledge, this will be the first study to investigate the efficacy of a CBT protocol aimed at reducing the risk of developing postpartum anxiety. Establishing this protocol as a potentially preventative strategy will offer a new option to improve the mental health and well-being of mothers and their infants.

A narrative review on emerging issues about war-related trauma in perinatal women: good practice for assessment, prevention, and treatment

BACKGROUND

Wars, in addition to causing death and destruction, have a negative impact on mental health, especially on perinatal women. The literature has identified psychological trauma as one of the most prevalent mental health issues associated with wars, but few studies have summarized how to assess, prevent, or treat this problem in perinatal women. To address this gap, the purpose of this study is to provide a narrative review of the current state of assessment, prevention, and treatment interventions of trauma among perinatal women living in war conditions or displaced as a result of a war.

METHOD

A literature search was performed in different research databases (e.g., Medline, PsycInfo). The search terms include a combination of trauma and stressor-related disorders and focused on diagnosis, prevention, and treatment.

RESULTS

Most of the results were related to post traumatic stress disorder (PTSD) more than acute stress disorder, although there are not many assessments, and interventions (prevention or treatment) dedicated specifically to perinatal women affected by war conditions.

CONCLUSION

Research in this area is still scarce. Recommendations for evidence-based practices in assessment and prevention and treatment interventions and future directions in research and clinical practice are provided.

HIGHLIGHTS

• The literature on trauma in perinatal women is sparse, and especially among perinatal women living in conditions of war. • This paper presents a narrative review of evidence-based assessment and treatment for perinatal women victims of war who experience trauma.

Partner military deployment and war conditions increase perinatal depression and decrease postpartum mother-infant bonding

The pregnancy and postpartum period represents a time of potentially heightened psychological vulnerability with implications for the offspring. Knowledge of the mental health of perinatal women exposed to armed conflict when their partner is in military deployment is scarce. This matched-control, survey-based study included a sample of 429 women recruited during the first months of the Israel-Hamas War who were pregnant or within six months postpartum. Women reporting partner in military deployment (n=250) were matched on background factors to women whose partner was no longer deployed (n=179). We found that nearly 44% of pregnant women with partner deployed endorsed depression symptoms at a clinical level. This group was more than two times as likely to endorse depression symptoms than matched controls. Postpartum women with partner deployed had significantly lower levels of mother-infant bonding than the matched group of partners not deployed. Mediation models revealed that social support mediated the relationship between study group and these maternal outcomes. Our findings suggest that war-exposed spouses of partners who are deployed are at increased risk for psychiatric morbidity and problems with attachment to the infant. Attention to optimizing social support in perinatal population is warranted during times of war and other large-scale traumas.

Brain health Begins Before Birth (B4): A "learning" pregnancy and birth cohort study

Mental health disorders affect over 1 billion people worldwide, profoundly impacting individuals, families, and the global economy. Risk for psychopathology begins early in life, with the perinatal period representing a critical window of vulnerability. The Brain health Begins Before Birth (B4) Study at Massachusetts General Hospital (MGH) is a prospective birth cohort designed to identify modifiable risk and resilience factors influencing early brain development and child- and adult-onset psychopathology. This study aims to deeply phenotype prenatal exposures through maternal surveys administered at multiple time points during and after pregnancy; assess early neurodevelopmental outcomes through the first two years of life; and triangulate exposure and outcome data with underlying biological mechanisms. The B4 Study consists of structured, remote surveys covering psychosocial, environmental, and health-related factors throughout pregnancy and the first two years of life, supplemented by medical record review. By integrating risk and resilience factors into a dynamic learning cohort model, the B4 Study aims to advance the field of preventive psychiatry by identifying actionable pathways for early intervention, testing strategies in real-time, and ultimately shaping policies that promote lifelong mental health and wellbeing from the earliest stages of development.

Network analysis of PTSD symptoms following childbirth and comorbid conditions among women with sexual trauma history

PURPOSE

Women with a history of sexual trauma (ST) have heightened risk for postpartum psychopathology. Although ST increases risk for traumatic delivery and maternal psychopathology, knowledge of the functional connections among various psychiatric symptoms and complicated delivery remains limited.

METHODS

We used regularized partial correlation networks to examine connections between symptoms of childbirth-related PTSD (CB-PTSD), depression, anxiety, somatization, obsessive-compulsive disorder, and complicated delivery (e.g., presence of obstetric complications, preterm birth, advanced maternal age) in 1,916 postpartum women. We compared networks of women with and without a history of sexual trauma (nST = 958 and nNST = 958, respectively).

RESULTS

Complicated delivery in both groups connected with three CB-PTSD clusters: reexperiencing, avoidance, and negative alterations in cognition and mood. Network comparison tests revealed a significant difference in global strength invariance, but not network invariance. ST network CB-PTSD nodes were significantly more strongly interconnected as compared to those with no ST (NST). Conversely, stronger connections in the NST network were Mood with Anxiety and Avoidance with Somatic symptoms.

CONCLUSION

The ST group's stronger PTSD symptom coactivation may reflect differences in risk for the emergence of CB-PTSD for women with a history of ST.

Psychometric properties of self-reported measures of psychological birth trauma in puerperae: A COSMIN systematic review

PURPOSE

To identify and evaluate the psychometric properties of available patient-reported outcome measures (PROMs) of psychological birth trauma (PBT) in postpartum women.

METHODS

A literature search was carried out across eight databases-PubMed, Embase, Web of Science, CINAHL, PsycINFO, China National Knowledge Infrastructure (CNKI), Wanfang Database, and VIP Database for Chinese Technical Periodicals-covering studies published from the inception of each database up to 21 May 2024. English and Chinese language studies employing any research design and reporting at least one psychometric property of PBT in puerperae were included. Independent reviewers extracted data and followed the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) guidelines to evaluate three aspects of the included instruments: methodological quality, psychometric properties, and level of evidence assessed using the modified Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework.

RESULTS

Thirty-one studies with twelve PROMs were included, measurement error, cross-cultural validity, and responsiveness were not reported for most PROMs. Nine PROMs received a Class B recommendation, based on their measurement attribute ratings and overall evidence quality. In contrast, the CTI, IES-R, and PBTAS with high-quality evidence for insufficient measurement properties, so received a Class C recommendation.

CONCLUSIONS

This systematic review provisionally recommends the City BiTS as credible tool for assessing PBT in both clinical practice and research involving puerperae. However, further comprehensive studies are needed to conduct more comprehensive validations of the psychometric properties of existing PROMs.

The Validation of the Perinatal Post-Traumatic Questionnaire in the Italian Population: Risk and Protective Factors

Background: Postpartum Post-Traumatic Stress Disorder (P-PTSD) symptoms develop after experiencing childbirth as traumatic. Several individual and environmental factors influence the childbirth experience. However, in Italy, this phenomenon remains unexplored due to the lack of screening tools. This project aims to validate the Italian version of the Perinatal PTSD Questionnaire (PPQ-II) and to identify maternal, pregnancy, childbirth, and postpartum risk and protective factors associated with P-PTSD. Methods: A total of 702 women (6-24 months postpartum) participated in an online cross-sectional study. They completed the PPQ-II, Depression Anxiety Stress Scales-21 (DASS-21), Big Five Inventory-10 (BFI-10), and a questionnaire to assess sociodemographic and perinatal factors. Factor structure was estimated with an exploratory (EFA) and confirmatory factor analysis (CFA). Internal consistency of the scale, convergent and divergent analyses were computed. Associations between perinatal factors and P-PTSD were also investigated. Results: The EFA revealed a two-factor structure: "Arousal and Mood alteration" and "Avoidance and Intrusion". CFA supported the factor structure, showing a good fit of the data. The validity was confirmed by a significant association between the PPQ-II and the DASS-21 and a lower correlation with the BFI-10. Significant associations were found between P-PTSD symptoms and factors across the maternal, pregnancy, childbirth, and postpartum periods. Conclusions: The Italian PPQ-II is a valid screening tool to include in maternity care protocols for the early identification of P-PTSD. This study also contributes to identifying perinatal factors for symptom detection and the promotion of maternal well-being.

AI and narrative embeddings detect PTSD following childbirth via birth stories

Free-text analysis using machine learning (ML)-based natural language processing (NLP) shows promise for diagnosing psychiatric conditions. Chat Generative Pre-trained Transformer (ChatGPT) has demonstrated preliminary initial feasibility for this purpose; however, whether it can accurately assess mental illness remains to be determined. This study evaluates the effectiveness of ChatGPT and the text-embedding-ada-002 (ADA) model in detecting post-traumatic stress disorder following childbirth (CB-PTSD), a maternal postpartum mental illness affecting millions of women annually, with no standard screening protocol. Using a sample of 1295 women who gave birth in the last six months and were 18+ years old, recruited through hospital announcements, social media, and professional organizations, we explore ChatGPT's and ADA's potential to screen for CB-PTSD by analyzing maternal childbirth narratives. The PTSD Checklist for DSM-5 (PCL-5; cutoff 31) was used to assess CB-PTSD. By developing an ML model that utilizes numerical vector representation of the ADA model, we identify CB-PTSD via narrative classification. Our model outperformed (F1 score: 0.81) ChatGPT and six previously published large text-embedding models trained on mental health or clinical domains data, suggesting that the ADA model can be harnessed to identify CB-PTSD. Our modeling approach could be generalized to assess other mental health disorders.
