The postnatal effects of perineal trauma on maternal psychological and emotional wellbeing: A longitudinal study.

OBJECTIVE: To examine the postnatal psychological health and parenting adjustment of primiparous women experiencing perineal trauma. STUDY DESIGN: Longitudinal cohort study assessing body image, perceptions of traumatic birth, psychological distress, perineal pain, impact upon parental tasks and mother-infant bonding at 6-12 weeks (n = 103) and 6-10 months postnatally (n = 91). Primiparous women were recruited following vaginal birth and perineal suturing in a UK-based maternity hospital. al. Comparisons made according to the objective classification of perineal trauma experienced; 1st/2nd degree tear, episiotomy, and Obstetric Anal Sphincter Injuries (OASI). RESULTS: At 6-12 weeks women with an episiotomy reported a more negative perception of their body image than those with OASI. Women with OASI or an episiotomy were more likely to have experienced birth as traumatic, and those with OASI reported more avoidance symptoms of post-traumatic stress and a greater negative impact on parenting tasks. At 6-10 months significantly more avoidance symptoms continued to be reported by those with OASI, whereas those with an episiotomy reported more anxiety related symptoms in general than those with OASI. CONCLUSIONS: OASI, whilst associated with traumatic birth and some early parenting impacts, may not be linked to general negative psychological outcomes when specialist routine follow-up care is provided. Psychological impacts for women with episiotomy may merit further input than currently provided. Consideration should be given with regards to widening the access to postnatal perineal care by extending the criteria for specialist follow up beyond those sustaining OASI.

An interpretive phenomenological analysis of the experiences of mothers who continue to breastfeed despite facing difficulties.

BACKGROUND: Breastfeeding offers many health benefits to mother and infant. PROBLEM: Breastfeeding difficulties are common and are linked with postnatal distress. AIM: To explore the lived experiences of breastfeeding continuation despite facing difficulties. METHODS: Qualitative semi-structured interviews were conducted with eight women who had experienced breastfeeding difficulties yet continued breastfeeding. Interviews were analysed using Interpretative Phenomenological Analysis (IPA). FINDINGS: The first superordinate theme, 'Radical acceptance of the imperfect' included sub-themes of: 'Taking it day-by-day', 'Breastfeeding takes a community', and, 'Finding what works for you'. The second superordinate theme, 'Determination and persistence' included sub-themes of: 'Adopting a headstrong attitude' and 'Transient challenges versus lifelong achievement'. DISCUSSION: Participants found radical acceptance of breastfeeding as an imperfect, variable process which enabled them to sustain breastfeeding despite challenges. Participants proactively drew on social and personal resources to navigate guidance and to find solutions which worked for their individual circumstances. Finally, open-mindedness, optimism, self-compassion, and being headstrong and determined were all personal qualities which facilitated breastfeeding during exceptionally difficult moments on their breastfeeding journey. CONCLUSION: Recommendations are made for healthcare professionals: to provide emotional counselling during routine care (with an aim to instil breastfeeding self-efficacy) and to encourage breastfeeding advocacy among fathers and the maternal social support network (with an aim to further scaffold successful breastfeeding). Recommendations are also made for mothers: to develop and refine maternal confidence, patience, flexibility, self-compassion, and trust.

Cognitive processing biases associated with fear of childbirth.

Fear of childbirth (FOC) is a phobic-like response concerning the prospect of giving birth. FOC can have negative implications for women during pregnancy and can impact their birthing experience. Cognitive processing biases (e.g., difficulty disengaging from threatening information, interpreting ambiguous information as threatening, and preferentially recalling threatening content) have previously been found to maintain general anxiety and low mood. To date, there has been no research assessing these attention, interpretation, and memory biases and their relationship with FOC in pregnant women. Accordingly, in this cross-sectional study, participants who were at least 12 weeks pregnant (n = 116), recruited through a local hospital trust, completed tasks assessing attention (emotional Stroop task), interpretation (scrambled sentences test), and explicit memory (recognition task) biases with materials including FOC-related content. They also completed three separate measures of FOC and measures of low mood, general anxiety, worry, and rumination. We found that a negative interpretation bias (but not attention or explicit memory biases) was associated with higher levels of FOC. These findings indicate that women presenting with higher FOC are more likely to demonstrate negative interpretation biases for ambiguous information relating to childbirth, which may inform research developing interventions to support women presenting with FOC.

Do antenatal preparation and obstetric complications and procedures interact to affect birth experience and postnatal mental health?

BACKGROUND: Antenatal preparation is commonly offered to women in pregnancy in the United Kingdom, but the content is highly variable, with some programmes orientated towards 'normal birth', whilst others may incorporate information about complications and procedures (broader focus). However, the impact of this variability on birth experience has not been explored. We examined the relationship between the content of antenatal preparation received and birth experience, taking into account obstetric complications and procedures. As birth experience can have a profound impact on a mother's postnatal well-being, we also investigated associations with mothers' postnatal mood and anxiety. METHODS: N = 253 first-time mothers completed a cross-sectional survey measuring demographic and clinical factors, antenatal preparation content (categorised as normality-focused or broader-focused), obstetric complications and procedures experienced, birth experience (measured using three separate indices; the Childbirth Experience Questionnaire, emotional experiences, and presence/absence of birth trauma), postnatal depression and anxiety, and qualitative information on how the COVID-19 pandemic had affected birth experience. RESULTS: Regarding birth experience, receiving more broader-focused preparation was associated with a more positive birth experience irrespective of complications/procedures experienced, while receiving only normality-focused preparation was beneficial in the context of fewer complications/procedures. Regarding birth trauma, receiving more broader-focused preparation was associated with lower likelihood of reporting birth as traumatic only in the context of more complications/procedures. Degree of normality-focused preparation was unrelated to experience of birth trauma. Lastly, while more complications/procedures were associated with greater anxiety and low mood, only greater normality-focused preparation was linked with better postnatal mental health. CONCLUSIONS: Antenatal preparation including both normality- and broader-focused information is positively related to women's birth experience. While normality-focused preparation seems most beneficial if fewer complications/procedures are experienced, broader-focused preparation may be most beneficial in the context of a greater number of complications/procedures. As complications/procedures are often unpredictable, offering broader-focused preparation routinely is likely to benefit women's birth experience. This antenatal preparation should be freely available and easily accessible.

The feasibility and acceptability of a single-session Acceptance and Commitment Therapy (ACT) intervention to support women self-reporting fear of childbirth in a first pregnancy.

OBJECTIVE: To assess the feasibility and acceptability of a single-session Acceptance and Commitment Therapy intervention to help women manage fear of childbirth during a first pregnancy. DESIGN: A mixed-methods approach including qualitative feedback and pre/post-intervention self-report measures. Pregnant women (14-37 weeks gestation) were recruited via the UK National Health Service and attended a single-session (<3 hours) Acceptance and Commitment Therapy intervention alongside routine antenatal care. Data were analysed using content and statistical analyses. MAIN OUTCOME MEASURES: Fear of childbirth, anxiety and wellbeing were the main outcome measures. Secondary to these, intolerance of uncertainty and valued life domains (e.g. relationships, recreation) as hypothesised mechanisms of change, were also assessed. RESULTS: 33 expressions of interest were received, 21 women signed up, 15 participated, and 11 completed follow-up measures (participation rate: 33%). Findings demonstrated clinical and statistical reductions in fear of childbirth and anxiety alongside positive feedback on the intervention. Intolerance of uncertainty and wellbeing were low at baseline and remained unchanged. CONCLUSION: A single-session Acceptance and Commitment Therapy intervention to manage fear of childbirth is potentially feasible and acceptable. A pilot randomised controlled trial is warranted. Further research should explore efficacy and how Acceptance and Commitment Therapy may reduce perinatal distress.

Which events are experienced as traumatic by obstetricians and gynaecologists, and why? A qualitative analysis from a cross-sectional survey and in-depth interviews.

OBJECTIVES: To explore the events perceived as traumatic by obstetricians and gynaecologists (O&G), and to examine factors contributing to the perception of trauma. DESIGN: Mixed methods: cross-sectional survey and in-depth interviews. SAMPLE AND SETTING: Fellows, members and trainees of the Royal College of Obstetricians and Gynaecologists (RCOG). METHODS: An online survey was distributed to 6300 fellows (May-June 2017), members and trainees of RCOG; 1095 (17%) completed surveys were returned. Of these, 728 (66%) reported work-related trauma experience, with 525 providing a brief description of an event. Forty-three participants with trauma experience were purposively sampled and completed an in-depth interview (October 2017-March 2018), which were analysed using Template Analysis. Information regarding the scale and impact of trauma experience is presented elsewhere. The present analysis provides new information describing the events and perceptions of why events were traumatic. PRIMARY OUTCOME MEASURES: The nature of traumatic events in this clinical setting, taken from survey descriptions of perceived traumatic events and information from the in-depth interviews. RESULTS: Events perceived as traumatic by O&G were similar between consultants, trainees and other RCOG members no longer working in O&G. Maternal or neonatal death/stillbirth, haemorrhage and events involving a difficult delivery were most frequently reported. Sudden and unpredictable events, perceived preventability, acute sensory experiences and high emotionality contributed to trauma perception. Respondents' trauma was compounded by an absence of support, involvement in investigation procedures and pre-existing relationships with a recipient of care. CONCLUSIONS: Identification of events most likely to be perceived as traumatic, and wider circumstances contributing to the perception of trauma, provide a basis on which to focus preventative and supportive strategies for O&G. Training on the nature of traumatic events, self-help for early stress responses, processing support and rapid access to trauma-focused psychological input (where required) are needed.

The importance of face to face, group antenatal education classes for first time mothers: A qualitative study.

OBJECTIVES: To explore and understand perspectives of women expecting their first child and why they wanted to attend NHS antenatal education. This included what worries and concerns they wanted to be addressed and why this would be beneficial. It also included what they wanted their partners to be able to gain from attending classes. DESIGN: A longitudinal qualitative study using Template Analysis was undertaken with data collection during pregnancy and postpartum. A semi-structured topic guide was used to guide data collection, either via focus groups or one to one interviews which were audio recorded and transcribed. SETTING: National Health Service Trusts providing maternity services to women for labour and birth, purposively selected to allow the perspectives of specific groups of women to be included. PARTICIPANTS: Women expecting their first child from one of three groups: Women from the general population aged 20 years or more, women from ethnic minority groups and young women aged 16 to 19 years. FINDINGS: Eighty-two pregnant women participated. Three substantive themes are reported: the search for information, the functions of antenatal classes, and the specific information desired. Women wanted to attend NHS antenatal education to access trustworthy information that would reassure, increase confidence, and help them feel prepared. Women wanted to meet others in the same situation to help normalise concerns and offer the potential for ongoing relationships. Classes were seen as a way to help partners engage more fully with the transition to parenthood. Specific information required and shared by all groups was around understanding the stages of labour, managing labour, and common interventions. CONCLUSIONS: Access to a wide range of information increases women's anxieties about labour that women want addressed through antenatal education. However, antenatal classes serve broader functions beyond information- giving and women anticipate that attending antenatal classes will address both their own and their partners' needs. IMPLICATIONS: Service providers should ensure their antenatal education provision provides the information required and is structured in a way that enables women to develop relationships and supports partners' engagement in the transition to parenthood.

Association of Task-Shared Psychological Interventions With Depression Outcomes in Low- and Middle-Income Countries: A Systematic Review and Individual Patient Data Meta-analysis.

Importance: Task sharing, the training of nonspecialist workers with no formal experience in counseling, is a promising strategy for addressing the large gap in treatment for depression in low- and middle-income countries (LMICs). Objective: To examine the outcomes and moderators of task-shared psychological interventions associated with depression severity, response, and remission. Data Sources: Systematic literature searches in PubMed, Embase, PsycINFO, and Cochrane Library up to January 1, 2021. Study Selection: Randomized clinical trials (RCTs) of task-shared psychological interventions compared with control conditions for adults with depressive symptoms in LMICs were included. Data Extraction and Synthesis: Two researchers independently reviewed the titles, abstracts, and full text of articles from an existing generic meta-analytic database that includes all RCTs on psychotherapy for depression. A systematic review and individual patient data (IPD) meta-analysis was used to estimate the outcomes of task-shared psychological interventions across patient characteristics using mixed-effects models. Procedures for abstracting data and assessing data quality and validity followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guideline. Main Outcomes and Measures: Primary outcome was reduction in depression symptom severity measured by the 9-item Patient Health Questionnaire (PHQ-9). Response and remission rates were also estimated. Results: Of 13 eligible trials, 11 (4145 participants) contributed IPD. Task-shared psychological interventions were associated with a greater decrease in depressive symptom severity than control conditions (Hedges g, 0.32; 95% CI, -0.26 to -0.38). Participants in the intervention groups had a higher chance of responding (odds ratio, 2.11; 95% CI, 1.60 to 2.80) and remitting (odds ratio, 1.87; 95% CI, 1.20 to 1.99). The presence of psychomotor symptoms was significantly associated with the outcomes of task-shared psychological interventions (ß [SE], -1.21 [0.39]; P = .002). No other significant associations were identified. Heterogeneity among the trials with IPD was 74% (95% CI, 53%-86%). Conclusions and Relevance: In this meta-analysis of IPD, task-shared psychological interventions were associated with a larger reduction in depressive symptom severity and a greater chance of response and remission than control conditions. These findings show potential for the use of task-sharing of psychological interventions across different groups of patients with depression. Further research would help identify which people are most likely to benefit and strengthen larger-scale implementation of this strategy to address the burden of depression in LMICs.

Protocol for the development of a core outcome set for stillbirth care research (iCHOOSE Study).

INTRODUCTION: Stillbirth is associated with significant physical, psychosocial and economic consequences for parents, families, wider society and the healthcare system. There is emerging momentum to design and evaluate interventions for care after stillbirth and in subsequent pregnancies. However, there is insufficient evidence to inform clinical practice compounded by inconsistent outcome reporting in research studies. To address this paucity of evidence, we plan to develop a core outcome set for stillbirth care research, through an international consensus process with key stakeholders including parents, healthcare professionals and researchers. METHODS AND ANALYSIS: The development of this core outcome set will be divided into five distinct phases: (1) Identifying potential outcomes from a mixed-methods systematic review and analysis of interviews with parents who have experienced stillbirth; (2) Creating a comprehensive outcome long-list and piloting of a Delphi questionnaire using think-aloud interviews; (3) Choosing the most important outcomes by conducting an international two-round Delphi survey including high-income, middle-income and low-income countries; (4) Deciding the core outcome set by consensus meetings with key stakeholders and (5) Dissemination and promotion of the core outcome set. A parent and public involvement panel and international steering committee has been convened to coproduce every stage of the development of this core outcome set. ETHICS AND DISSEMINATION: Ethical approval for the qualitative interviews has been approved by Berkshire Ethics Committee REC Reference 12/SC/0495. Ethical approval for the think-aloud interviews, Delphi survey and consensus meetings has been awarded from the University of Bristol Faculty of Health Sciences Research Ethics Committee (Reference number: 116535). The dissemination strategy is being developed with the parent and public involvement panel and steering committee. Results will be published in peer-reviewed specialty journals, shared at national and international conferences and promoted through parent organisations and charities.

Psychological variables and quality of life in women with endometriosis.

BACKGROUND: Endometriosis is a common gynecological condition which has been found to have a detrimental impact upon women's quality of life (QoL). This study investigated the impact of pain self-efficacy, health locus of control (HLOC), coping style and illness uncertainty on QoL in women with endometriosis. METHOD: Two hundred and thirty women completed online questionnaires. Standard multiple regressions assessed the relationship between the psychological predictors and QoL. RESULTS: The psychological variables accounted for a statistically significant proportion of the variance (p < .0005) in scores across the four QoL domains. The model accounted for 55, 26, 10 and 32% of the scores in physical, psychological, social and environmental QoL domains, respectively. Pain self-efficacy made the largest unique contribution, followed by illness uncertainty. CONCLUSIONS: Women's perception of their ability to manage their pain and how uncertain they felt about their condition, were important factors in QoL, particularly in the physical domain.

The effects of perineal trauma on immediate self-reported birth experience in first-time mothers.

INTRODUCTION: Childbirth can sometimes be stressful or traumatic, and previous research has considered how birth complications and interventions may contribute to a negative birth experience. One of the most frequent complications during birth is trauma to the perineum. The aim of this study was to investigate whether different levels of perineal trauma were associated with differences in women's evaluation of their birth experience. MATERIALS AND METHODS: As part of a longitudinal cohort study, the self-reported birth experiences of 202 primiparous women were compared based on the degree of perineal trauma they had experienced. Women who had given birth for the first time, vaginally and within the last 48 h in a large tertiary maternity unit in England were invited to take part. Data were collected from their hospital records with their consent and using the Childbirth Experience Questionnaire (CEQ), Experience of Birth Scale (EBS) and a perineal pain Visual Analogue Scale (VAS). RESULTS: Women with an obstetric anal sphincter injury (OASI) or episiotomy reported a more negative overall birth experience and perceived themselves as having less ability to give birth compared to those with a 1st/2nd degree sutured tear. Those with an episiotomy also reported feeling less involved in decision making processes during their birth. Significant differences remained between the OASI and 1st/2nd degree tear groups when controlling for factors known to affect birth experience, highlighting severe perineal trauma as a potential contributor to more negative birth experience. CONCLUSIONS: Perineal trauma may affect a woman's birth experience. Experiencing an episiotomy should not be overlooked as a potential contributor, especially during instrumental birth and in the absence of involved decision making. Further research is needed to disentangle the effects of episiotomy on birth experience, to explore the care needs of women with different degrees of perineal trauma and to explore how a negative birth experience may contribute to poor psychological health in the longer term.

A new scale for fear of childbirth: the Fear of Childbirth Questionnaire (FCQ).

OBJECTIVE: To create a clear and acceptable measure of fear of childbirth with satisfactory content validity for use with English-speaking women in the UK. BACKGROUND: Fear of childbirth (FOC) can have a significant impact on a woman's view of her pregnancy, birth and her recovery post birth. Early identification is paramount to ensure that women's needs are recognised so that appropriately tailored care can be provided in pregnancy. Availability of reliable and valid measures to assess FOC in an English-speaking population are sparse, mainly due to issues with definitions of FOC or cultural sensitivity after translation. Recent research from phase one of the Fear of Childbirth study (FOCUS), has established key elements for FOC in an English-speaking UK population, and allows for a culturally sensitive measure of FOC to be developed. The aim was to ensure inclusion of all ten FOC elements and to attend to guidance from women in phase two of the FOCUS study about what would ensure clarity and acceptability. METHOD: A multidisciplinary team developed items in accordance with FOCUS. The measure was then piloted with one reviewer and further refined by the team of perinatal researchers. RESULTS: The FCQ is a new 20-item fear of childbirth questionnaire, which has been developed and is grounded in fears reported by women in the UK. CONCLUSION: A new tool to measure FOC in an English-speaking UK population with good content validity has undergone a preliminary phase of development and now needs testing for reliability and other forms of validity.

Facilitating Perinatal Access to Resources and Support (PeARS): a feasibility study with external pilot of a novel intervention.

BACKGROUND: Up to 50% of women in areas of high socio-economic deprivation are at risk of developing depressive symptoms in pregnancy. Feeling well supported, can facilitate good mental health perinatally. A brief, innovative intervention to facilitate access to support and resources was developed and tested. This included one antenatal and one postnatal session, each with three evidence-based components: i) support from a non-professional peer to enable a woman to identify her needs; ii) information about local community services and signposting; and iii) development of a personalised If-Then plan to access that support. The aims were to evaluate the intervention and research methods for feasibility and acceptability for perinatal women, maternity care providers and peers, and provide preliminary effectiveness indications. METHODS: Pregnant women living in an area of high deprivation were recruited from community-based antenatal clinics and randomised to intervention or control condition (a booklet about local resources). Outcome measures included women's use of community services by 34 + weeks gestation and 6 months postnatally; mental health and wellbeing measures, and plan implementation. Interviews and focus groups were conducted with women participants, providers, and peers. Data were analysed using framework analysis. Recruitment and retention of peers and participants, intervention fidelity, and acceptability of outcome measures were recorded. RESULTS: Peer facilitators could be recruited, trained, retained and provide the intervention with fidelity. One hundred twenty six women were recruited and randomised, 85% lived in the 1% most deprived UK areas. Recruitment constituted 39% of those eligible, improving to 54% after midwifery liaison. Sixty five percent were retained at 6 months postnatally. Women welcomed the intervention, and found it helpful to plan access to community services. Providers strongly supported the intervention philosophy and integrated this easily into services. The study was not powered to detect significant group differences but there were positive trends in community service use, particularly postnatally. No differences were evident in mental health and wellbeing. CONCLUSIONS: This intervention was well received and easily integrated into existing services. Women living in highly deprived areas could be recruited, randomised and retained. Measures were acceptable. Peer facilitators were successfully trained and retained. Full effectiveness studies are warranted.

The birth trauma psychological therapy service: An audit of outcomes.

OBJECTIVE: To evaluate routinely collected service data from a 'Birth Trauma' psychology clinic integrated into maternity services, in order to review effectiveness for women with symptoms of Post-Traumatic Stress Disorder (PTSD) following childbirth. BACKGROUND: Prevalence of PTSD after child-birth has been estimated to be around 3% for women meeting full diagnostic criteria and up to 9% for sub-threshold symptoms. This can occur even in response to deliveries considered to be medically straightforward. NICE guidelines (2018) recommend psychological therapy as a first line treatment for symptoms of PTSD. METHODS: The sample included 114 women referred post-natally for psychological assessment and intervention following a traumatic birth experience. Measures were routinely administered as part of initial assessment (T1) and at completion of intervention (T2). Data from these measures were collated and analyzed using a series of paired sample t tests. Following assessment 101 women were taken on for psychological intervention and of these, 74 completed both T1 and T2 measures. RESULTS: There were highly significant reductions across all measures of PTSD, anxiety and negative mood symptoms. The treatment effect sizes were very large. Mean total score on a measure of PTSD symptomatology was no longer clinically significant following interventions. CONCLUSION: This evaluation suggests an integrated Birth Trauma psychology clinic using a small number of contact sessions is a highly efficient and effective model of care for women experiencing symptoms of PTSD following childbirth.

Do stress and anxiety in early pregnancy affect the progress of labor: Evidence from the Wirral Child Health and Development Study.

INTRODUCTION: Despite widespread belief that anxiety causes longer labor, evidence of association is inconsistent. Data gathered as part of a prospective epidemiological longitudinal study were used to investigate associations between antenatal anxiety and pregnancy-specific stress, and labor progression was assessed by duration and use of augmentation. MATERIAL AND METHODS: Pregnant primiparous women completed measures for anxiety and pregnancy-specific stress at 20 weeks' gestation (n = 1145). Birth outcome data were extracted from medical records. Regression analyses and a path analysis assessed associations between antenatal anxiety and pregnancy-specific stress, and indices of labor progression (labor duration and augmentation). RESULTS: Anxiety/pregnancy-specific stress were not directly associated with duration of stage 1 labor (HIGH/LOW anxiety: mean difference = 13.94 minutes, SD = 20.66, 95% CI -26.60 to 54.49, P < .50)/(HIGH/LOW pregnancy-specific stress: mean difference = 12.05 minutes, SD = 16.09, 95% CI -19.52 to 43.63, P < .45). However, anxiety/pregnancy-specific stress were associated with epidural use (HIGH/LOW anxiety: 39% vs 31%, P < .042; HIGH/LOW pregnancy-specific stress: 38% vs 29%, P < .001), which was itself associated with longer labor (mean difference: 158.79 minutes, SD = 16.76, 95% CI 125.89-191.68, P < .001). Anxiety and pregnancy-specific stress were associated with increased likelihood of augmentation but these associations were nonsignificant after accounting for epidural, which was itself highly associated with augmentation. However, path analysis indicated an indirect effect linking pregnancy-specific stress, but not general anxiety, to labor duration and augmentation: elevated pregnancy-specific stress led to greater use of epidural, which was linked to both increased rates of augmentation, and increased labor duration. CONCLUSIONS: Contrary to general belief, general anxiety and specific pregnancy stress were not directly linked to longer duration of stage one labor. However specific pregnancy stress was associated with epidural use, which in turn was significantly associated with risk of augmentation, and longer stage one labor. Identification of pregnancy-specific stress could help to identify women for whom psychological interventions could improve birth experience.

Personality factors and vulnerability to post-traumatic stress responses after childbirth.

OBJECTIVES: To investigate whether levels of perfectionism, organization, and intolerance of uncertainty predispose women to more negative birth experiences and post-partum post-traumatic stress symptoms (PTSS). Birth experience was also examined as a potential moderator of the relationship between levels of the personality traits and post-natal PTSS. DESIGN: Prospective survey. METHOD: First-time expectant mothers (N = 10,000) were contacted via Emma's Diary during the perinatal period. At 32-42 weeks' gestation, participants completed measures examining the three personality traits and prenatal mood. At 6-12 weeks' post-partum, instruments assessing childbirth experience, birth trauma, PTSS, and post-natal mood were completed. Data from 418 women were analysed. RESULTS: Higher perfectionism and intolerance of uncertainty were associated with more negative birth appraisals and PTSS. Organization was unrelated to birth experience or PTSS. In a regression, higher intolerance of uncertainty and perfectionism statistically predicted more negative birth appraisals. Only perfectionism predicted PTSS. Birth experience did not moderate the relationship between perfectionism or intolerance of uncertainty and PTSS. CONCLUSIONS: Personality risk factors for negative birth experiences and post-natal PTSS are identifiable prenatally. Maternity care providers could educate women about the unique roles of high perfectionism and intolerance of uncertainty during antenatal birth preparation. PRACTITIONER POINTS: Women who expect themselves to be more perfect or who find it more difficult to cope with uncertainty had more negative experiences of childbirth. Women with higher levels of perfectionism were more likely to experience more symptoms of post-traumatic stress during the early post-natal period. Being more perfectionistic continued to have a more negative effect on women's well-being after birth, regardless of whether they had a positive or negative experience of birth. Integrating these findings into antenatal discussion around birth preferences would increase women's awareness of predisposing and obstetric risk factors that partially explain experiences of unsatisfactory births and post-partum post-traumatic stress.
