Practitioner perspectives on the use of selected fear of childbirth screening tools within a clinical context.

Fear of childbirth (FOC), or tokophobia, can influence several medical and obstetric variables, and is a significant predictor of maternal and mental health outcomes and birth experiences. Current practice in the UK does not include initial screening for tokophobia, rather, assessment and support occur under extreme circumstances e.g. maternal requests for caesarean sections or pregnancy termination requests in order to avoid childbirth. Moreover, while there are several candidate outcome measures for FOC, none have been evaluated in terms of their perceived suitability by specialist practitioners within perinatal healthcare pathways. The present study explores the perceived barriers and facilitators reported by health professionals working within the maternity and mental health services for the use of FOC candidate outcome measures. Evaluated measures included the Fear of Birth Scale, the Oxford Worries about Labour Scale, The Wijma Delivery Expectancy Scale, the Slade-Pais Expectations of Childbirth Scale the Tokophobia Severity Scale. The Tokophobia Severity Scale, followed by the Slade-Pais Expectations of Childbirth Scales were the most favourable scales selected for use according to clinicians. The identification of preferred scales and how they can be used in the local maternity system is a step towards the application of these consistently in clinical practice, to aid in the identification and assessment of FOC. The use of the correct tool at each stage of contact with the local maternity system will improve clinician confidence in the identification of FOC and facilitate the efficient implementation of treatment and support through the development of pathways of care.

The Tokophobia Severity Scale (TSS): measurement model, power and sample size considerations.

OBJECTIVE: To examine the measurement model of the Tokophobia Severity Scale and consider issues of statistical power and sample size from the original instrument development study. BACKGROUND: Fear of childbirth (FoC) and tokophobia represents an area of increasing concern within perinatal mental health research and clinical practice. Existing measures of the FoC have been criticised due to either measurement inconsistencies, difficulties in scoring or practical clinical application. Attempting to address these limitations, researchers developed the Tokophobia Severity Scale (TSS). A fundamental assumption underpinning the use of the TSS is unidimensionality, however this assertion may have been based on sub-optimal sample size and approach taken to factor structure determination. METHOD: Parallel analysis (PA), principal components analysis (PCA), exploratory factor analysis (EFA), power analysis and sample size calculation using a reconstruction of the original dataset from published summary data. RESULTS: Following replication of the original PCA, a three-factor model was found to offer a significantly better fit to data than a unidimensional model. Power analysis suggested the original study was underpowered. CONCLUSION: The TSS remains a promising tool but assumptions regarding its measurement model are based on an inadequate sample size. Sample sizes for a sufficiently powered study indicated.

Fear of childbirth measurement: appraisal of the content overlap of four instruments.

OBJECTIVE: To evaluate empirically the degree of content overlap between four self-report measures of fear of childbirth (FoC) identified as 'best in class' by a recent review. BACKGROUND: FoC and tokophobia is an area of increasing clinical concern and has been linked to poor maternal and neonatal outcomes. Clinical pathways have been established to improve care and interventions for FoC however, ambiguity and inconsistency remain regarding the most appropriate assessment measures. METHOD: A multi-rater and consensus content analysis was undertaken to determine the degree of overlap between four 'best in class' measures of FoC/tokophobia. RESULTS: The Slade-Pais expectations of childbirth scale (SPECS) was found to be the preferred measure in terms of symptom overlap of the tools evaluated, however, the overall level of overlap among these measures was weak. CONCLUSION: Limitations inherent to the current battery of preferred measures of FoC suggests both the desirability and urgency to develop a theoretically-grounded, psychometrically robust and accurate FoC assessment measure. Current measures of FoC are not interchangeable.

The Relationship between Maternal Personality Disorder and Early Birth Outcomes: A Systematic Review and Meta-Analysis.

(1) Background: Women with personality disorder are at risk of social and emotional problems which impact deleteriously on everyday functioning. Moreover, a personality disorder diagnosis has been established to have an adverse impact upon pregnancy outcomes and child health. Understanding this impact is critical to improving both maternal and child outcomes. This systematic review and meta-analysis will evaluate the contemporary evidence regarding these relationships. (2) Methods: Prospero and Cochrane were searched for any systematic reviews already completed on this topic. Academic Search Premier, CINAHL Complete, MEDLINE, PsycARTICLES, PsycINFO via the EBSCO host, and the Web of Science Core Collection were searched to include research articles published between 1980 and 2019. A total of 158 records were identified; 105 records were screened by reviewing the abstract; 99 records were excluded; 6 full text articles were assessed for eligibility; 5 records were included in the review. (3) Results: All the included studies reported on preterm birth. The meta-analysis indicates significant risk of preterm birth in women with personality disorder (overall odds ratio (OR) 2.62; CI 2.24-3.06; p < 0.01). Three studies reported on low birth weight, with the meta-analysis indicating a raised risk of low birth weight of the babies born to women with personality disorder (overall OR 2.00 CI 1.12-3.57 (p = 0.02)). Three studies reported on appearance, pulse, grimace, activity, and respiration (APGAR) score, with the meta-analysis of OR's indicating a risk of low APGAR score in women with personality disorder (overall OR 2.31; CI 1.17-4.55; p = 0.02). (4) Conclusions: The infants of women with personality disorder are at elevated risk of preterm birth, low birth weight and low APGAR score.
