Construct Validity and Psychometric Properties of the Hebrew Version of the City Birth Trauma Scale

Translation and Validation of the City Birth Trauma Scale With Lithuanian Postpartum Women: Findings and Initial Results

The childbirth experience and birth-related trauma are influenced by various factors, including country, healthcare system, a woman's history of traumatic experiences, and the study's design and instruments. This study aimed to validate the City Birth Trauma scale for Lithuanian women post-childbirth. Using a descriptive, cross-sectional survey with a nonprobability sample of 794 women who gave birth from 2020-2021, the study found good validity, reliability, and presented the prevalence of birth-related stress symptoms. A bifactor model, consisting of a general birth trauma factor and two specific factors for birth-related symptoms and general symptoms of PTSD, showed the best model fit. The Lithuanian version of the City Birth Trauma scale can be effectively used in research and clinical practice to identify birth-related trauma symptoms in women after giving birth.

Risk psychosocial factors associated with postpartum depression trajectories from birth to six months

PURPOSE

The purpose of this study was to assess the trajectory of women's depressive symptoms during the first six months postpartum, identify risk factors (sociodemographic, obstetric and personality) associated with classes, and examine associations between classes and postpartum PTSD at two months and bonding at six months.

METHODS

The final sample included 212 women who gave birth in the maternity wards of a large tertiary health center that were approached at 1-3 days, two months, and six months postpartum and completed a demographic questionnaire and measures of neuroticism (BFI) and postpartum depression (EPDS), postpartum PTSD (City Birth Trauma Scale) and bonding (PBQ). Obstetric data were taken from the medical files.

RESULTS

Cluster analysis revealed three distinctive clusters: "stable-low" (64.2%), "transient-decreasing" (25.9%), and "stable-high" (9.9%). Neuroticism, general-related PTSD symptoms, and bonding were associated with differences between all trajectories. Birth-related PTSD symptoms were associated with differences between both stable-high and transient-decreasing trajectories and the stable-low trajectory. No obstetric or demographic variables were associated with differences between trajectories.

CONCLUSION

We suggest that screening women for vulnerabilities such as high levels of neuroticism and offering treatment can alleviate the possible deleterious effects of high-symptom depression trajectories that may be associated with their vulnerability.

Development, women-centricity and psychometric properties of maternity patient-reported outcome measures (PROMs): A systematic review

BACKGROUND

Measuring maternity care outcomes based on what women value is critical to promoting woman-centred maternity care. Patient-reported outcome measures (PROMs) are instruments that enable service users to assess healthcare service and system performance.

AIM

To identify and critically appraise the risk of bias, woman-centricity (content validity) and psychometric properties of maternity PROMs published in the scientific literature.

METHODS

MEDLINE, CINAHL Plus, PsycINFO and Embase were systematically searched for relevant records between 01/01/2010 and 07/10/2021. Included articles underwent risk of bias, content validity and psychometric properties assessments in line with COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidance. PROM results were summarised according to language subgroups and an overall recommendation for use was determined.

FINDINGS

Forty-four studies reported on the development and psychometric evaluation of 9 maternity PROMs, grouped into 32 language subgroups. Risk of bias assessments for the PROM development and content validity showed inadequate or doubtful methodological quality. Internal consistency reliability, hypothesis testing (for construct validity), structural validity and test-retest reliability varied markedly in sufficiency and evidence quality. No PROMs received a level 'A' recommendation, required for real-world use.

CONCLUSION

Maternity PROMs identified in this systematic review had poor quality evidence for their measurement properties and lacked sufficient content validity, indicating a lack of woman-centricity in instrument development. Future research should prioritise women's voices in deciding what is relevant, comprehensive and comprehensible to measure, as this will impact overall validity and reliability and facilitate real-world use.

Maternal childbirth-related posttraumatic stress symptoms, bonding, and infant development: a prospective study

BACKGROUND

Childbirth-related posttraumatic stress symptoms (CB-PTSS) including general symptoms (GS, i.e., mainly negative cognitions and mood and hyperarousal symptoms) and birth-related symptoms (BRS, i.e., mostly re-experiencing and avoidance symptoms) may disrupt mother-infant bonding and infant development. This study investigated prospective and cross-sectional associations between maternal CB-PTSS and mother-infant bonding or infant development (language, motor, and cognitive).

METHOD

We analysed secondary data of the control group of a randomised control trial (NCT03576586) with full-term French-speaking mother-infant dyads (n = 55). Maternal CB-PTSS and mother-infant bonding were assessed via questionnaires at six weeks (T1) and six months (T2) postpartum: PTSD Checklist for DSM-5 (PCL-5) and Mother-Infant Bonding Scale (MIBS). Infant development was assessed with the Bayley Scales of Infant Development at T2. Sociodemographic and medical data were collected from questionnaires and medical records. Bivariate and multivariate regression were used.

RESULTS

Maternal total CB-PTSS score at T1 was associated with poorer bonding at T2 in the unadjusted model (B = 0.064, p = 0.043). In the adjusted model, cross-sectional associations were found at T1 between a higher total CB-PTSS score and poorer bonding (B = 0.134, p = 0.017) and between higher GS and poorer bonding (B = 0.306, p = 0.002). Higher BRS at T1 was associated with better infant cognitive development at T2 in the unadjusted model (B = 0.748, p = 0.026).

CONCLUSIONS

Results suggest that CB-PTSS were associated with mother-infant bonding difficulties, while CB-PTSS were not significantly associated with infant development. Additional studies are needed to increase our understanding of the intergenerational consequences of perinatal trauma.

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.

The latent factor structure and assessment of childbirth-related PTSD: psychometric characteristics of the City Birth Trauma Scale-Persian version (City-BiTS-P)

Objective

There is no validated Persian questionnaire to measure childbirth-related PTSD (CB-PTSD) symptoms. To cover this gap, the present study aimed to provide a Persian version of the City Birth Trauma Scale (CityBiTS-Pr) and to determine its psychometric properties.

Method

Since this is a cross-sectional study, sampling was done using a convenient sampling method. In total, 300 Persian-speaking women took part in this study and completed the City Birth Trauma Scale (CityBiTS-Pr), the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5), the Edinburgh Postnatal Depression Scale (EPDS), the Anxiety Subscale of the Depression, and the Anxiety and Stress Scale (DASS-21). In addition, sociodemographic information was completed. A confirmatory factor analysis of two- and four-factor models and a bi-factor model with a general factor and two specific factors were tested. Fit indices were calculated for all three models. Reliability, convergent, divergent, and discriminant validity also were examined. R v4.2.1 and SPSS v23 were used for data analysis.

Results

The four-factor model comprised intrusion, avoidance, negative cognitions and mood, and hyper-arousal showed a poor fit. The two-factor model composed of "birth-related symptoms" and "general symptoms" provided the best results based on all fit indices. The bi-factor result was relatively good, but the loadings indicated that the general symptoms factor is not well defined.

Conclusion

The Persian version of the City Birth Trauma Scale (CityBiTS-Pr) is a valid and reliable questionnaire for evaluating postpartum PTSD.

Assessment of childbirth-related post traumatic stress disorder in Australian mothers: Psychometric properties of the City Birth Trauma Scale

BACKGROUND

The City Birth Trauma Scale (BiTS; Ayers, Wright & Thornton, 2018) is self-report measure of Post-Traumatic Stress Disorder (PTSD) symptoms following childbirth, based on DSM-5 criteria. We report on the first study of the psychometric properties of the BiTS in the Australian population.

METHODS

Participants were mothers of infants aged 0-12 months (N = 705), who completed the BiTS and measures of related constructs. Confirmatory factor analysis was performed to assess the factor structure of the BiTS. Examination of the reliability, convergent, divergent and discriminant validity and acceptability of the BiTS was also examined.

RESULTS

Confirmatory factor analysis supported a bi-factor model of Birth-related Symptoms (BRS) and General Symptoms (GS) of post-partum PTSD as well as a global CB-PTSD factor. Internal consistency was found for the BiTS total scale and two proposed subscales (BRS and GS). BiTS total scores were significantly associated with an established measure of PTSD, providing support for convergent validity. Evidence of discriminant validity was examined by comparing the BiTS to an established measure of postpartum depression.

LIMITATIONS

The present sample may over-represent participants with traumatic birth experiences in comparison to the general public. Furthermore, use of self-report measures limits the capacity to confirm the diagnostic status of participants.

CONCLUSION

These findings suggest that the BiTS is a valid and reliable measure of childbirth-related PTSD, suited for use in postpartum populations. Total scores on the measure may be informative for clinical and research purposes, while evidence suggests strong support for interpretation of subscale scores.

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.

Epidural analgesia associations with depression, PTSD, and bonding at 2 months postpartum

The research aim was to study the possible effect of epidural analgesia, as well as other possible demographic/obstetric variables and subjective birth experience on postpartum depression, PTSD, and impaired bonding. This was a longitudinal study of 254 women who gave birth at the maternity wards of a large tertiary health center and responded to questionnaires at T1 (Childbirth Experience Questionnaire and level of fatigue question; in person, 1-4 days postpartum) and at T2 (Postnatal Depression Scale, Postpartum Bonding Questionnaire, and the City Birth Trauma Scale; online-two months postpartum). Obstetric and demographic data were taken from medical files. Having a previous psychiatric diagnosis and higher levels of fatigue significantly predicted worse outcomes in all measures (level of fatigue was not associated with the City Birth Trauma birth-related symptoms factor). Having higher education, being primiparous, worse birth experience, and longer second stage of birth predicted worse outcomes in some measures. Although epidural administration had no effect on any of the outcome variables, special attention should be devoted to women who had long second-stage births and/or suffering from postpartum fatigue to prevent postpartum psychopathology. In addition, demographic variables, such as primiparity, education, and prior psychopathology diagnosis should be considered to treat women and prevent postpartum psychopathology.

Auricular acupuncture for sleep quality in participants with mental and behavioral disorders due to prior multiple drug use: a retrospective consecutive case series

BACKGRUOUND

Poor sleep quality is associated with psychoactive substance abuse/addiction/withdrawal. Auricular acupuncture (AA) is a nonpharmacological method used for the treatment of sleep disturbances. This study aimed to examine the quality of sleep before and after AA in participants with mental and behavioral disorders due to prior multiple drug use in the therapeutic community.

METHODS

This was a consecutive case series of 27 participants (25 male [92.6%]). The median age was 35.0 years (interquartile range [IQR], 29.0-37.2 years), methadone/buprenorphine were not used, and the participants were treated with AA (median number of treatments, 15.0 [IQR, 12.0-18.0]) during a median period of 51.0 days (IQR, 49.0-51.0 days) according to the National Acupuncture Detoxification Association (NADA)-Acudetox protocol. Sleep quality was determined using the Pittsburgh Sleep Quality Index (PSQI), a self-rated questionnaire that assesses sleep quality and disturbances over a 1-month interval.

RESULTS

The global PSQI score dropped (indicating better sleep quality) by a median of 3.0 points (IQR, 0.0-8.0 points) after treatment. In the multivariate logistic regression analysis, with an increase in global PSQI score during AA by 1 point, there was a 0.73-fold reduction in the risk of poor sleep quality post-AA (adjusted odds ratio, 0.73; 95% confidence interval, 0.52-1.01; p<0.055; Nagelkerke's R2=0.66).

CONCLUSION

The results revealed a positive effect of AA (by the NADA-Acudetox protocol) on sleep quality (as measured by PSQI) among participants in a treatment center with mental and behavioral disorders due to multiple drug use.

Patient-reported outcome measures evaluating postpartum maternal health and well-being: a systematic review and evaluation of measurement properties

OBJECTIVE

This study aimed to systematically review and evaluate postpartum health and well-being using patient-reported outcome measures across all domains of postpartum health using the COnsensus-based Standards for the selection of health Measurement INstruments guidelines.

DATA SOURCES

Based on a preprepared published protocol, a systematic search of PubMed, Embase, and CINAHL was undertaken to identify patient-reported outcome tools. The protocol was registered with the International Prospective Register of Systematic Reviews (registration number CRD42021283472), and this work followed the COnsensus-based Standards for the selection of health Measurement INstruments guidelines for systematic reviews.

STUDY ELIGIBILITY CRITERIA

Studies eligible for inclusion included those that assessed a patient-reported outcome measure examining postpartum women's health and well-being with no limitation on the domain. The included studies aimed to evaluate one or more measurement properties of the patient-reported outcome measure.

METHODS

Data extraction and the methodological assessment of the quality of the patient-reported outcome measure were assessed by 2 reviewers independently based on content validity, structural validity, internal consistency, cross-cultural validity or measurement invariance, reliability, measurement error, hypotheses testing for construct validity, and responsiveness, as defined by the COnsensus-based Standards for the selection of health Measurement INstruments. The standard used for content validity were the domains of importance to women in postpartum health and well-being proposed by the International Consortium for Health Outcomes Measurement. The outcome domains for patient-reported health status include mental health, health-related quality of life, incontinence, pain with intercourse, breastfeeding, and motherhood role transition. The quality of the methods was rated an overall rating of results, awarded a level of evidence, and assessed using the Grading of Recommendations, Assessment, Development, and Evaluations assessment tool, and a level of recommendation was awarded for each tool.

RESULTS

There were 10,324 studies identified in the initial search, of which 29 tools were identified from 41 eligible studies included in the review. Moreover, 21 tools were awarded an "A" grading of recommendation for use as a patient-reported outcome measure in postpartum women following the COnsensus-based Standards for the selection of health Measurement Instruments standards. Of the "A"-rated tools, 17 (80%) examined the domain of mental health, 5 examined health-related quality of life, 4 examined breastfeeding, and 6 represented role transition. No "A"-recommended tool examined postpartum incontinence or pain with intercourse. Of note, 3 tools did not cover domains as recommended by the International Consortium for Health Outcomes Measurement, and 5 tools were awarded a "B" rating, requiring more research before their recommendation for use. Here, most tools were awarded very low-moderate Recommendations, Assessment, Development, and Evaluations level of evidence. Moreover, the highest quality tool identified that covered multiple domains of postpartum health and well-being was the women's Postpartum Quality-of-Life Questionnaire.

CONCLUSION

This systematic review identified the best performing patient-reported outcome measures to assess postpartum health and well-being. No individual tool covers all 6 domains of postpartum health and well-being. Here, the highest quality tool found that covered multiple domains of postpartum health and well-being was the Postpartum Quality-of-Life Questionnaire. The Postpartum Quality-of-Life Questionnaire captures 4 of 6 domains of importance to women, with domains of incontinence and sexual health unevaluated. The domain of urinary incontinence was represented by the International Consultation on Incontinence Questionnaire Short Form, which requires further psychometric analysis before its recommended use. Postpartum sexual health, not represented by any tool, necessitates the development of a patient-reported outcome measure. A postpartum patient-reported outcome measure would be best provided by a combination of tools; however, further research is required before its implementation.

Birth-related PTSD symptoms and related factors following preterm childbirth in Turkey

Objective: To examine factors associated with birth-related post-traumatic stress disorder (PTSD) among women who had preterm birth in their last pregnancy in Turkey.Methods: 304 women were asked to report sociodemographic factors, perinatal factors, birth-related factors, preterm birth/premature infant characteristics, and social support factors and PTSD symptoms. Data were collected using online surveys between November 2020 and February 2021. Hierarchical multiple linear regression was used. Results: The prevalence of birth-related PTSD symptoms following preterm birth was 71.1%. Older age, the woman being positively affected by her own mother's birth experience, not having traumatic experience in pregnancy and in the postnatal period, lower stress level after traumatic events experienced during birth, not feeling that their life/physical integrity was at risk during birth, having amniotomy, feeling psychologically well after childbirth, not being negatively affected by witnessing other parents' happy moments with their babies in friend/family groups, the absence of infant illness and mother's reporting higher positive interactions with healthcare team were associated with decreased likelihood of birth-related PTSD. Except for age and traumatic event in the postnatal period, all the variables explained 43% of the variance with a small effect size (f 2  = 0.04). Stress level after the traumatic events experienced during labor was the strongest predictor of birth-related PTSD symptoms (β = 0.33). Conclusion: Wellbeing of mother and baby, facilitating interventions at labor, and positive communication with the healthcare team was associated with lower birth-related PTSD symptoms. The study findings highlighted on birth-related PTSD symptoms in mothers of preterm infants in Turkey.

Posttraumatic stress following childbirth: psychometric properties of the Brazilian version of the City Birth Trauma Scale

OBJECTIVE

To seek validity and reliability evidence of the Brazilian version of the City Birth Trauma Scale (BiTS-Br) and establish diagnostic accuracy.

METHOD

A total of 343 mothers (up to one year after childbirth, 30.8 years old on average) completed the BiTs-Br and other instruments screening for posttraumatic stress disorder (PTSD), depression, and anxiety for convergent validity analysis. Structural validity was verified using exploratory techniques (principal components analysis), while discriminant validity was checked using the known-groups method and ROC curve. The Structured Clinical Interview for DSM-5 was applied via telephone interviews. Test-retest reliability was obtained in a 15-30-d interval.

RESULTS

A two-factor structure was found (birth-related and general symptoms), with excellent test-retest reliability (0.73) and internal consistency (0.91). Moderate/strong associations (>0.62) were found with correlated symptoms and posttraumatic stress. The scale had a diagnostic accuracy of 86.7% and a cutoff point >28 was the most appropriate, with a sensitivity of 72% and specificity of 83%.

CONCLUSIONS

BiTS-Br presented excellent psychometric indexes, similar to the original version and other cross-culturally adapted versions. Thus, it can be widely used in scientific research and clinical settings to support the identification and treatment of PTSD.

Measuring posttraumatic stress disorder following childbirth

PURPOSE

This study aims to assess the reliability and construct validity of the City Birth Trauma Scale (BiTS) in Oceania and confirm the latent factor structure of postpartum posttraumatic stress disorder (PTSD).

METHODS

Participants completed the City BiTS, demographic and obstetric information via an online survey. Psychometric properties of the City BiTS were investigated using confirmatory factor analyses (CFA).

RESULTS

The study included 195 women, with 39 participating in repeat administration. CFA confirmed a two-factor model which included a birth-related symptom (BRS) subscale and general symptom (GS) subscale. High reliability and construct validity was observed for subscales and total score at baseline and follow-up.

CONCLUSION

The City BiTS represents a potentially useful tool to assist with screening for postpartum PTSD.

Two are better than one? The impact of lay birth companions on childbirth experiences and PTSD

Although continuous support during childbirth is recommended by the World Health Organization (WHO) and has well-established benefits, the practice is still not routinely implemented in all maternity settings. We studied the possible effect of an additional lay companion (other than the partner) on childbirth experience and postpartum post-traumatic stress disorder (PTSD). Two hundred and forty-six women, who gave birth in maternity wards of a large tertiary health center in Israel, responded to questionnaires in person at 1-4 days (Demographic questions and the childbirth experience questionnaire) and on-line at 8-10 weeks postpartum (City Birth Trauma Scale). Obstetric data were taken from the medical files. Women who were accompanied by their partners and an additional companion were lower in birth-related PTSD symptoms (M = 1.17, SD = 2.61) than women accompanied by only their partner (M = 1.53, SD = 2.79) (F(2, 240) = 4.0, p < 0.05). Women who had a single companion (M = 1.44, SD = 2.61) showed more birth-related PTSD symptoms than women who had two or more companions (M = 1.17, SD = 2.52) (F(1, 241) = 6.4, p < 0.05). In addition, women who had a single companion were higher in general PTSD symptoms (M = 3.91, SD = 4.73) than women who had two or more companions (M = 2.31, SD = 4.29) (F(1, 241) = 4.2, p < 0.05). No differences were found in childbirth experiences of women with single or multiple companions. Allowing more than one lay companion (other than the partner) may be a simple cost-effective way of providing beneficial support in all birth settings, promoting respectful maternity care and reducing childbirth-related PTSD levels and by that future psychopathology sequela.

The use of personal protective equipment as an independent factor for developing depressive and post-traumatic stress symptoms in the postpartum period

Background

New recommendations regarding the use of personal protective equipment (PPE) during delivery have changed the maternal birth experience. In this study, we investigated the mental perceived impact of PPE use during delivery on the development of maternal postpartum depression (PPD) and post-traumatic stress symptoms (PTSS).

Methods

This was a multicenter, retrospective cohort study concerning women who delivered during the COVID-19 pandemic first lockdown period in Israel. Postpartum women were approached and asked to complete a comprehensive online questionnaire. Impact of PPE was graded on a scale of 1–5, and Impact of PPE ≥4 was considered high. PPD and PTSS were assessed using the EPDS and City BiTS questionnaires.

Results

Of 421 parturients, 36 (9%) reported high Impact of PPE. Parturients with high Impact of PPE had significantly higher PPD and PTSS scores)EPDS 8.4 ± 5.8 vs. 5.7 ± 5.3; City BiTS 9.2 ± 10.3 vs. 5.8 ± 7.8, p < 0.05 for both). Following adjustment for socio-demographic and delivery confounders and fear of COVID-19 (using Fear of COVID19 scale), Impact of PPE remained positively correlated with PPD symptoms (ß = 0.103, 95% confidence intervals [CI] 0.029–1.006, p = 0.038).

Conclusion

When examining the risk factors for developing postpartum PTSS—experiences during labor and PPE were found to be significant variables. As the use of PPE is crucial in this era of COVID-19 pandemic in order to protect both parturients and caregivers, creative measures should be taken in order to overcome the communication gap it poses.

Development and Validation of a Measure of Birth-Related PTSD for Fathers and Birth Partners: The City Birth Trauma Scale (Partner Version)

Research suggests that some fathers and birth partners can experience post-traumatic stress disorder (PTSD) after witnessing a traumatic birth. Birth-related PTSD may impact on many aspects of fathers’ and birth partners’ life, including relationship breakdown, self-blame and reducing plans for future children. Despite the potential impact on birth partners’ lives there is currently no measure of birth-related PTSD validated for use with birth partners. The current study therefore adapted the City Birth Trauma Scale for use with birth partners. The City Birth Trauma Scale (Partner version) is a 29-item questionnaire developed to measure birth-related PTSD according to DSM-5 criteria: stressor criteria (A), symptoms of re-experiencing (B), avoidance (C), negative cognitions and mood (D), and hyperarousal (E), as well as duration of symptoms (F), significant distress or impairment (G), and exclusion criteria or other causes (H). A sample of 301 fathers/birth partners was recruited online and completed measures of birth-related PTSD, bonding, and demographic details. Results showed the City Birth Trauma Scale (Partner version) had good reliability (α = 0.94) and psychometric and construct validity. The fathers/birth partners version has the same two-factor structure as the original scale: (1) general symptoms and (2) birth-related symptoms, which accounted for 51% of the variance. PTSD symptoms were associated with preterm birth and maternal and infant complications. Overall, the City Birth Trauma Scale (Partner version) provides a promising measure of PTSD following childbirth that can be used in research and clinical practice.

Post-traumatic stress disorder following childbirth

BACKGROUND

Childbirth experience could be complicated and even traumatic. This study explored the possible risk factors for post-traumatic stress disorder following childbirth (PTSD-FC) in mothers and partners.

METHODS

Through a cross-sectional online survey biographical, medical, psychological, obstetrical and trauma history data were collected. The PTSD-FC, postnatal depression, social support, and perceived mother-infant bond in 916 mothers and 64 partners were measured through self-reported psychometric assessments.

RESULTS

Our findings highlight the possible impact of several risk factors such as emergency childbirth, past traumatic experiences and distressing events during childbirth on PTSD-FC. The difficulties in mother-infant bond and the postpartum depression were highly associated with the total score of PTSD-FC symptoms for mothers. While for partners, post-partum depression was highly associated with the total score of PTSD-FC.

CONCLUSIONS

Our study demonstrated significant links between psychological, traumatic and birth-related risk factors as well as the perceived social support and the possible PTSD following childbirth in mothers and partners. Given that, a specific attention to PTSD-FC and psychological distress following childbirth should be given to mothers and their partners following childbirth.

The association of attachment style, postpartum PTSD and depression with bonding- A longitudinal path analysis model, from childbirth to six months

BACKGROUND

There is substantial evidence that postpartum depression (PPD) is associated with a poor mother-infant bond, however, fewer studies have examined the role of other postpartum psychopathologies such as birth-related PTSD or relevant trait variables such as adult attachment styles in the quality of the mother-infant bond.

METHODS

210 postpartum women were sampled in a maternity ward of a tertiary health care center. Participants completed questionnaires at three-time points. Demographics questionnaire and the Adult Attachment style scale were administrated at 1-4 days postpartum, the City Birth Trauma Scale and the Edinburgh Postpartum Depression Scale two months postpartum and the Postpartum Bonding questionnaire at six months postpartum.

RESULTS

The associations between adult attachment styles and postpartum bonding were fully mediated by postpartum psychopathology. Avoidant attachment had indirect effects on bonding through general PTSD symptoms (Beta=0.05, p=.019) and PPD (Beta=0.06, p=.010). Anxious attachment also had indirect effects on bonding through general PTSD symptoms (Beta=0.04, p=.044) and PPD (Beta=0.10, p=.001). In contrast, birth-related PTSD symptoms were not associated with bonding. The model presented a good fit.

LIMITATIONS

Women sampled from one health-care center and self-report measures used.

CONCLUSIONS

Our results suggest that although birth-related PTSD symptoms may cause difficulties, importantly they may not be associated with bonding difficulties six months postpartum. Therefore, women could be reassured that their birth-related PTSD symptoms, may not impact on bonding. Consequently, if interventions are specifically aimed at improving the mother-infant bond, the general-related PTSD, PPD symptoms and insecure attachment styles should be the focus of treatment.

Assessment of Childbirth-Related PTSD: Psychometric Properties of the German Version of the City Birth Trauma Scale

Background: About 3-4% of women in community samples suffer from childbirth-related posttraumatic stress disorder (PTSD). Surprisingly, the recently developed City Birth Trauma Scale (City BiTS) was the first diagnostic tool for childbirth-related PTSD covering DSM-5 criteria for PTSD. Since no questionnaire on childbirth-related PTSD is available in German, we aimed to validate a German translation of the City BiTS and to provide information on its psychometric properties. Methods: A community sample of 1,072 mothers completed an online survey, which included questions on sociodemographic and obstetric characteristics, the German version of the City BiTS, the Impact of Event Scale-Revised (IES-R), the PTSD Checklist for DSM-5 (PCL-5), Edinburgh Postnatal Depression Scale (EPDS), and the anxiety subscale of the Depression, Anxiety, and Stress Scale (DASS-Anxiety). Results: Exploratory factor analysis (EFA) on a random split-half sample confirmed the previously reported two-factorial structure of the City BiTS. The factors "Childbirth-related symptoms" and "General symptoms" explained about 53%, 52% of variance. Internal consistency was good to excellent for the subscales and the total scale (Cronbach's Alpha = 0.89-0.92). In a confirmatory factor analysis (CFA) in the holdout sample the two-factorial solution reached the best model fit out of three models. Correlation analyses showed convergent validity of the City BiTS (total scale and subscales) with the IES-R and PCL-5 and divergent validity with the EPDS and the DASS-Anxiety. Limitations: Data were acquired in a community sample and prevalence rates might not be representative for mothers of high-risk groups, e.g., after preterm birth. Conclusions: The German version of the City BiTS is the first German questionnaire which allows to assess symptoms of childbirth-related PTSD according to DSM-5 criteria. Besides an improvement in clinical routine it will help to make data on prevalence of childbirth-related PTSD internationally comparable. In addition, this work provides a basis to assess childbirth-related PTSD in studies conducted with a longitudinal study design or in high-risk samples.

Validity and reliability of the Turkish version of the City Birth Trauma Scale (CityBiTS)

The City Birth Trauma Scale (CityBiTS) was developed to be consistent with the current Diagnostic and Statistical Manual of Mental Disorders-DSM-5. It has been used as a complementary instrument that measures the psychological trauma related to childbirth. The aim of this study was to investigate the validity and reliability of the Turkish version of the CityBiTS. This research is a methodological study. This study was conducted with 315 women who had 6-month-old infants from August to October 2018. The CityBiTS is a 29-item instrument that was developed according to DSM-5 criteria to assess childbirth-related Post-Traumatic Stress Disorder. Test-retest measurements were performed at two-week intervals to evaluate the invariance of the scale over time. Cronbach's alpha coefficient of reliability was used to analyse internal consistency of scale. Cronbach's alpha coefficients were .76 for re-experiencing symptoms, .57 for avoidance symptoms, .77 for negative cognitions and mood, .83 for hyperarousal and .82 for dissociative symptoms. In conclusion, The Turkish version of the CityBiTS, as an instrument developed to be consistent with DSM-5 criteria in assessing childbirth-related trauma symptoms, is a valid and reliable tool.Impact statementWhat is already known on this subject? One of the possible barriers for this is the lack of validated questionnaires that measure the postpartum PTSD.What do the results of this study add? The aim of this study was to investigate the validity and reliability of the Turkish version of the CityBiTS. The City Birth Trauma Scale has good psychometric properties and the two symptom clusters identified are consistent with previous research on symptoms of postpartum PTSD.What are the implications of these findings for clinical practice and/or further research? The City Birth Trauma Scale provides with a measure of birth-related PTSD foruse in research and clinical practice.

Health-care practitioners' assessment and observations of birth trauma in mothers and partners

BACKGROUND

Evidence shows that traumatic childbirth can cause ongoing distress, often referred to as birth trauma. This can have an impact on parents and the couple relationship, and consequently identifying and supporting parents with birth trauma is important to practice.

AIM

To investigate the experiences of health-care practitioners from the United Kingdom (UK) in assessment for birth trauma, perceived occurrence of birth trauma and observed impact on parents and the couple relationship.

METHODS

An online survey of UK health-care practitioners working with parents in the first postnatal year.

RESULTS

A sample of 202 practitioners reported identifying birth trauma in 34.4% of mothers and 25.0% of partners. Assessment for birth trauma was only conducted for 50.3% of mothers and 25.9% of partners. The most observed symptoms were re-experiencing among mothers (87.1%) and avoidance among partners (50.9%). Birth trauma was perceived as impacting on the couple relationship for 29.8% of mothers and 26.9% of partners. Written responses provided more detailed observations of the impact of birth trauma.

CONCLUSION

Understanding how birth trauma may present differently in mothers and partners could support effective assessment. Once birth trauma is identified, parents require personalised support to help them cope with the impact.
