Worldwide prevalence of tocophobia in pregnant women: systematic review and meta-analysis

Introduction: Tocophobia is defined as a severe fear of pregnancy and childbirth. There is increasing evidence that tocophobia may have short-term and long-term adverse effects on mother and baby. We performed a systematic review and meta-analysis to determine the global prevalence of tocophobia in pregnancy. Material and methods: Relevant articles were identified through searching six relevant databases: MEDLINE, CINAHL, Pubmed, PsycINFO, Maternity & Infant Care and Scopus between 1946 and April 2016. We used search terms for tocophobia prevalence in pregnant women that we agreed with a medical librarian. There were no language restrictions. Two review authors independently assessed data for inclusion, extracted data and assessed quality using a standardized appraisal tool. Meta-analysis was performed to determine the overall pooled-prevalence of tocophobia. Several subgroup and sensitivity analyses were conducted. Results: Thirty-three studies were included in the systematic review from 18 countries of which data from 29 studies were used in the meta-analysis of 853 988 pregnant women. Definition of tocophobia varied, whereas prevalence rates ranged between 3.7 and 43%. The overall pooled prevalence of tocophobia, using a random-effects model, was 14% (95% CI 0.12â 0.16). Significant heterogeneity was observed (I2 = 99.25%, p = 0.00), which was not explained in subgroup analyses including tocophobia definition used, screening trimester and parity. Conclusion: The prevalence of tocophobia is estimated at 14% and appears to have increased in recent years (2000 onwards). Considerable heterogeneity (99.25%) was noted that may be attributed to lack of consensus on the definition of tocophobia, so our results should be interpreted with caution

Establishing a valid construct of fear of childbirth: Findings from in-depth interviews with women and midwives

Background: Fear of childbirth (FOC) can have a negative impact on a woman’s psychological wellbeing during pregnancy and her experience of birth. It has also been associated with adverse obstetric outcomes and postpartum mental health difficulties. However the FOC construct is itself poorly defined. This study aimed to systematically identify the key elements of FOC as reported by women themselves. Methods: Semi-structured interviews with pregnant women (n= 10) who reported to be fearful of childbirth and telephone interviews with consultant midwives (n= 13) who regularly work with women who are fearful of childbirth were conducted. Interviews were analysed using thematic analysis for each group independently to provide two sources of information. Findings were reviewed in conjunction with a third source, a recently published meta-synthesis of existing literature of women’s own accounts of FOC. The key elements of FOC were determined via presence in two out of the three sources at least one of which was from women themselves, i.e. the reports of the women interviewed or the meta-synthesis. Results: Seven themes were identified by the women and the consultant midwives: Fear of not knowing and not being able to plan for the unpredictable, Fear of harm or stress to the baby, Fear of inability to cope with the pain, Fear of harm to self in labour and postnatally, Fear of being ‘done to’, Fear of not having a voice in decision making and Fear of being abandoned and alone. One further theme was generated by the women and supported by the reports included the meta-synthesis: Fear about my body’s ability to give birth. Two further themes were generated by the consultant midwives and were present also in the meta synthesis: Fear of internal loss of control and Terrified of birth and not knowing why. Conclusions: Ten key elements in women’s FOC were identified. These can now be used to inform development of measurement tools with verified content validity to identify women experiencing FOC, to support timely access to support during pregnancy

Psychological perspectives on fear of birth : heterogeneity, mechanisms and treatment

Although it is medically safe to give birth in most western countries, the vast majority of pregnant women experience some kind of anxiety, fear or worry in relation to their pregnancy or the upcoming childbirth. Most pregnant women find ways of coping with these issues but, for many, fear of birth is a significant source of distress during pregnancy, with negative consequences both when giving birth and in the postpartum period. Previous research on fear of birth has for the most part had a medical perspective, investigating risk factors and consequences of this form of fear or anxiety, along with studies evaluating different forms of interventions. The general aim of this thesis was to approach fear of birth from a psychological perspective, by exploring the role of psychological factors in this form of fear, worry or anxiety. Four studies are included in the thesis. The first study is a randomized controlled trial, in which we compared a guided Internet-delivered self-help program, based on cognitive behavior therapy (guided ICBT), with standard care (midwife led fear of birth specific counseling), for the treatment of fear of birth. Despite poor adherence to the guided ICBT, the results showed a similar reduction in fear levels during pregnancy in both groups, with lower levels of fear of birth in the guided ICBT group one year after birth. The second study is a narrative literature review. This study adopted a psychological perspective on the existing literature describing fear of birth, with a special focus on the specificity of this form of fear or anxiety, the pathways of fear acquisition, and the physiological, cognitive and behavioral aspects of fear of birth. Using systematic procedures for the literature search, inclusion and exclusion, 89 original research papers were included and summarized in the study. The aim of the third study was to explore possible heterogeneity among pregnant women reporting high levels of fear of birth. Comparisons between primiparous and multiparous women revealed that these groups were very similar in their levels of fear of birth as well as in the psychological variables investigated. Using a series of hierarchical and non-hierarchical cluster analyses, five possible subgroups based on psychological characteristics were identified, pointing to psychological heterogeneity among women fearing birth. In the fourth study, our aim was to take a first step in trying to identify psychological mechanisms relevant to the understanding of fear of birth. In this study, pain catastrophizing and intolerance of uncertainty were clear predictors of fear of birth, while parity was not. Taken together, the results of the four studies included in this thesis indicate that fear of birth is a concept in need of further investigation, and that psychological perspectives could offer an important contribution to our understanding of this form of fear or anxiety. Women fearing birth seem to be a heterogeneous group, and psychological characteristics (e.g. pain catastrophizing, or catastrophizing in general, and intolerance of uncertainty) might be of greater importance than parity in both describing this diversity and understanding the development and maintenance of fear of birth. Treating fear of birth using guided ICBT can be challenging, and before introducing this form of treatment as an alternative, further refinement and evaluation of the methods are needed.Även om det medicinskt sett är förhållandevis säkert att föda barn i Sverige och andra västerländska länder, uppger de flesta gravida kvinnor att de känner en viss mån av rädsla, oro eller ångest kopplat till graviditeten eller den väntande förlossningen. De flesta kvinnor hittar ett sätt att hantera dessa upplevelser, men för många blir rädsla och oro inför förlossningen ständiga följeslagare under graviditeten. Den befintliga forskningen om förlossningsrädsla har huvudsakligen utgått ifrån ett medicinskt perspektiv. Förlossningsrädsla har kopplats till olika riskfaktorer och till negativa konsekvenser i samband med förlossningen eller under den närmaste tiden därefter. Ett antal studier har också utvärderat olika interventioner för att förebygga eller behandla förlossningsrädsla. Huvudsyftet med denna avhandling har varit att undersöka förlossningsrädsla utifrån ett psykologisk perspektiv, och fokus har därmed legat på att studera psykologiska faktorers betydelse i relation till denna form av rädsla, oro eller ångest. Avhandlingen innehåller fyra studier. Den första är en randomiserad kontrollerad studie, i vilken vi har jämfört effekterna av Internet-baserad kognitiv beteendeterapi med terapeutstöd och svensk standardvård (samtalsstöd med barnmorska) vid förlossningsrädsla. Trots lågt deltagande i den kognitiva beteendeterapin minskade graden av förlossningsrädsla på ett jämförbart sätt i båda behandlingsgrupperna under graviditeten, och ett år efter födseln var graden av rädsla något lägre i gruppen som erbjudits kognitiv beteendeterapi. Avhandlingens andra studie är en narrativ litteraturöversikt, som ger ett psykologiskt perspektiv på den befintliga forskningen om förlossningsrädsla. I studien sammanfattas fynd från 89 vetenskapliga artiklar, med ett särskilt fokus på resultat som kan ge oss ledtrådar om hur specifik denna form av rädsla är, rädslans olika inlärningsvägar, samt kognitiva, fysiologiska och beteendemässiga aspekter av förlossningsrädsla. Den tredje studien syftade till att undersöka potentiell heterogenitet bland gravida kvinnor med hög grad av förlossningsrädsla. Jämförelser mellan förstföderskor och omföderskor visade att dessa grupper var förhållandevis lika avseende grad av rädsla och psykologiska karakteristika. Istället identifierades fem möjliga subgrupper utifrån kvinnornas svarsmönster på psykologiska självskattningsinstrument. Resultaten från denna studie tyder på att skillnaderna mellan först- och omföderskor kanske inte är så stora i detta avseende, men att det kan finnas andra källor till psykologisk heterogenitet bland kvinnor med hög grad av förlossningsrädsla. Syftet med den fjärde studien var att ta ett första steg för att identifiera psykologiska mekanismer av betydelse för förståelsen för förlossningsrädsla. Höga självskattningar av smärtkatastrofiering och intolerans för osäkerhet predicerade hög grad av förlossningsrädsla. Däremot hade det ingen betydelse för graden av rädsla om deltagarna var först- eller omföderskor. Sammantaget tyder resultaten från de fyra studierna på att förlossningsrädsla är ett fenomen som behöver studeras närmare, och att psykologiska perspektiv kan vara av betydelse för att öka vår förståelse för denna form av rädsla, ångest eller oro. Kvinnor med förlossningsrädsla tycks tillhöra en heterogen grupp, och psykologiska karakteristika såsom grad av smärtkatastrofiering eller intolerans för osäkerhet skulle kunna vara av större betydelse än paritet (d.v.s. om kvinnan är först- eller omföderska) för att beskriva denna mångfald och förstå hur förlossningsrädsla utvecklas och vidmakthålls. Att behandla förlossningsrädsla med Internet-baserad kognitiv beteendeterapi har sina utmaningar, och innan ett sådant behandlingsalternativ kan introduceras inom mödravården krävs fortsatt förfining och utvärdering av metoden

Psychologists' experiences of working with fear of childbirth : implications and advice for care providers

BACKGROUND AND AIM: Fear of childbirth is a common problem that affects women's health and wellbeing. A variety of interventions have been used in research and clinical settings, but it remains unclear how interventions should be designed to be as effective and acceptable as possible. Additionally, the experiences of psychologists working to support women fearing childbirth are sparsely documented and therefore unavailable for researchers and clinicians. This qualitative study aimed to bridge this gap by exploring and describing the experiences of perinatal psychologists working clinically with women suffering from fear of childbirth. METHODS: Focus group interviews with eleven psychologists, analysed with reflexive thematic analysis with an inductive and semantic approach. RESULTS: We identified four main themes, with three to four subthemes each. It was described as essential to meet the woman where she stands: to listen, validate, explore, and tailor interventions. Depending on the needs of each woman, the psychologists had a smorgasbord of core interventions to offer. They also described how they could help the woman and her partner or support person to prepare for childbirth. Finally, they addressed the importance of multiprofessional engagement and cooperation. A list of recommendations based on the findings is presented. CONCLUSION: The findings add to the existing literature on how to treat and support women with fear of childbirth and should be considered as one of many sources of information guiding the development of future interventions, care strategies, and clinical pathways for women fearing childbirth

Validity and reliability of the WHOQOL-BREF in a pregnant population

Abstract Background Physical end emotional changes during pregnancy may not only affect pregnant womens’ quality of life, but also how instruments assessing quality of life perform in such populations. To date, there is insufficient evidence on psychometric properties for both generic and condition-specific instruments measuring quality of life during pregnancy. The aim of this study was thus to examine the structural validity, internal consistency, and construct validity of the WHOQOL-BREF in a sample of pregnant women. Methods A convenience sample of 1015 pregnant women in Sweden completed the WHOQOL-BREF online. We examined the psychometric properties of the instrument using principal component analysis (PCA), confirmatory factor analysis (CFA), Cronbach’s alpha, item-domain correlations, correlations with overall QOL and general health, and multiple linear regression with items on overall QOL and general health as outcomes. Results Principal Component Analysis in a random subsample (n = 502) supported a four-factor model, encompassing the domains physical, psychological, social and environmental quality of life, but with four of the items originally in the environmental domain relocated to the other domains. The proposed domain structure showed good fit in confirmatory factor analysis in the other random subsample (n = 513). The physical and psychological domains showed good internal consistency (Cronbach’s alpha = 0.885 and 0.826 respectively), while the social and environmental domains were weaker in this regard. All domains showed significant positive correlations with items on overall QOL and general health. The physical and psychological domains were the most evident predictors in the regression models. Conclusions We find the Swedish version of the WHOQOL-BREF to have good psychometric properties to be used in samples of pregnant women, and propose an alternative domain structure that might be even more useful for assessing quality of life during pregnancy. The physical and psychological domains showed good internal consistency and construct validity

Preconception fear of childbirth : experiences and needs of women fearing childbirth before first pregnancy.

BACKGROUND: Although early case studies have indicated that fear of childbirth can predate a woman's first pregnancy, the concept of preconception fear of childbirth is largely unexplored. The few studies reporting on the prevalence of preconception fear of childbirth found higher levels than most prevalence estimates in pregnant populations. However, little is known about women's fear of childbirth before becoming pregnant. The aim of this qualitative study was to give voice to the experiences of this often-neglected group of women. METHODS: To address the experiences and needs of women who do not dare become pregnant due to fear of childbirth, we conducted nine qualitative interviews and analyzed these using reflexive thematic analysis. RESULTS: The women perceived childbirth as an extremely risky event and doubted their abilities to cope with it. With increasing age, the fear became more real. It was associated with thoughts of becoming too old to be able to conceive. The women did their best to cope with fear on their own by seeking information, trying not to think about it, and using multiple strategies to avoid becoming pregnant. Despite expressing a strong wish for professional support, they all described very limited opportunities to receive support from maternal care services. They felt abandoned, left on their own in a stressful and constantly ongoing negotiation with themselves, feeling the pressure to decide whether to dare become pregnant or not. CONCLUSION: In this study, women expressed having experienced fear of childbirth long before a first pregnancy. They felt abandoned as they had to deal with their fear by themselves, without support from maternal care services. The results point to the necessity of an increased awareness of preconception fear of childbirth. We encourage maternal care services to consider their opportunities to support these women

The factor structure of the cardiac anxiety questionnaire, and validation in a post-MI population

Abstract Background CVD-patients with higher levels of cardiac anxiety suffer psychologically, as well as being at increased risk for cardiac morbidity and mortality. Therefore it is important to be able to assess CA in a clinical setting. It is currently measured with the Cardiac Anxiety Questionnaire, which has conflicting findings regarding its factor structure, and it has not been validated in a Swedish population. This study aimed to examine the factor structure of CAQ and its psychometric properties in a Swedish CVD-population. Methods Nine hundred thirty patients post-MI were recruited at different Swedish hospitals and completed the CAQ, along with several other questionnaires. Exploratory factor analysis and confirmatory factor analysis were conducted to explore factor structure and to inspect various factor solutions from previous research. Standard psychometric tests were performed for the CAQ to test its validity and reliability. Results The exploratory analysis found a model with the factors Fear/Worry, Avoidance and Attention. The confirmatory factor analysis indicated that a 3-factor solution best fitted the data, but with certain items removed. Additionally, psychometric properties turned out acceptable in a Swedish post-MI population. Conclusions We conclude that the original 3-factor structure of the CAQ is valid, but that the questionnaire could be revised in regard to some items. A shorter 10-items version could also be considered. We also confirm that the CAQ is a valid instrument to measure CA in a Swedish MI-population. Trial registration The study was registered on ClinicalTrials.gov on 05/01/2012 (NCT01504191)

Association of anxiety and recurrent cardiovascular events : investigating different aspects of anxiety

Aims While elevated levels of anxiety are associated with worse prognosis of cardiovascular disease (CVD), this association may vary between different aspects of anxiety. The aim of this study was to analyse self-reported behavioural, physiological, affective, and cognitive aspects of anxiety and their relation to the risk of recurrent CV events.Methods and results This prospective cohort study utilized data from the U-CARE Heart trial. Participants (N = 935, post myocardial infarction) answered the Hospital Anxiety and Depression Scale (HADS: Anxiety subscale) and the Cardiac Anxiety Questionnaire (CAQ: Fear, Avoidance & Attention subscales). HADS Anxiety reflected physiological aspects, CAQ Fear reflected cognitive and affective aspects, CAQ Avoidance reflected behavioural aspects, and CAQ Attention reflected cognitive aspects of anxiety. Cox regression was used to estimate the risk between anxiety and recurrent major adverse cardiac event (MACE). During the follow-up period (mean 2.9 years), 124 individuals (13%) experienced a specified MACE endpoint. HADS Anxiety and CAQ Total were both associated with increased risk of MACE [hazard ratio (HR) = 1.52, 95% confidence interval (CI): 1.15-2.02 and HR = 1.30, 95% CI: 1.04-1.64, respectively]. Among the CAQ subscales, there was support for an association between Avoidance and risk of MACE (HR = 1.37, 95% CI 1.15-1.64), but not for Attention and Fear.Conclusion The results support that anxiety is associated with an increased risk of recurrent MACE in post-myocardial infarction patients. The association between anxiety and risk was strong for the aspects of anxiety relating to behaviour and physiology, while the support for an association with cognitive and affective aspects was lacking.
