Phenotypic Environmental Sensitivity and Mental Health During Pregnancy and Post Partum: Protocol for the Experiences of Pregnancy Longitudinal Cohort Study

BACKGROUND

Mental health problems during pregnancy and post partum are common and associated with negative short- and long-term impacts on pregnant individuals, obstetric outcomes, and child socioemotional development. Socio-environmental factors are important predictors of perinatal mental health, but the effects of the environment on mental health are heterogeneous. The differential susceptibility theory and the environmental sensitivity framework suggest that individuals differ in their degree of sensitivity to positive and negative environments, which can be captured by individual phenotypes such as temperament and personality. While there is strong evidence for these models in childhood, few studies examined them in adults, and they were not examined in pregnancy.

OBJECTIVE

The primary objective of the Experiences of Pregnancy study is to explore whether childhood and current environments are associated with mental health and well-being in pregnancy and whether these effects depend on individual sensitivity phenotypes (personality). This study also aims to gather important psychosocial and health data for potential secondary data analyses and integrative data analyses.

METHODS

We will conduct a longitudinal cohort study. The study was not registered elsewhere, other than this protocol. Participants will be recruited through social media advertisements linking to the study website, followed by an eligibility call on Zoom (Zoom Video Communications). Participants must be aged 18 years or older, currently residing in the United States as citizens or permanent residents, and currently planning to continue the pregnancy. A minimum of 512 participants will be recruited based on power analyses for the main objectives. Since the data will also be a resource for secondary analyses, up to 1000 participants will be recruited based on the available budget. Participants will be in their first trimester of pregnancy, and they will be followed at each trimester and once post partum. Data will be obtained through self-reported questionnaires assessing demographic factors; pregnancy-related factors; delivery, labor, and birth outcomes; early infant feeding; individual personality factors; childhood and current environments; mental health and well-being; attachment; and infant temperament. A series of measures were taken to safeguard the study from web robots and fraudulent participants, as well as to reduce legal and social risks for participants following Dobbs v. Jackson.

RESULTS

The study received ethics approval in April 2023 from the University of Oklahoma-Norman Campus Institutional Review Board. Recruitment occurred from May to August 2023, with 3 follow-ups occurring over 10 months.

CONCLUSIONS

The Experiences of Pregnancy study will extend theories of environmental sensitivity, mainly applied in children to the perinatal period. This will help better understand individual sensitivity factors associated with risk, resilience, plasticity, and receptivity to negative and positive environmental influences during pregnancy for pregnant individuals.

Evaluating the development, woman-centricity and psychometric properties of maternity patient-reported outcome measures (PROMs) and patient-reported experience measures (PREMs): A systematic review protocol

INTRODUCTION

Woman-centred care is the right of every woman receiving maternity care, irrespective of where care is being received and who is providing care. This protocol describes a planned systematic review that will identify, describe and critically appraise the psychometric properties of maternity patient-reported outcome measures (PROMs) and patient-reported experience measures (PREMs). The woman-centricity of PROM and PREM development and content validation (ie, the extent to which women were involved in these processes) will also be assessed. This information will be used to develop a maternity PROMs and PREMs database to support service and system performance measurement, and value-based maternity care initiatives.

METHODS AND ANALYSIS

This study will be guided by the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guideline for systematic reviews of outcome measurement instruments. Studies identified via MEDLINE, CINAHL Plus, PsycINFO and EMBASE describing the development, content validation and/or psychometric evaluation of PROMs and PREMs specifically designed for maternity populations throughout pregnancy, childbirth and postnatal periods will be considered if published from 2010 onward, in English, and available in full text. The COSMIN risk of bias checklist will be used to evaluate the quality of studies reporting on the development, content validation and/or psychometric evaluation of PROMs and PREMs. COSMIN criteria for good content validity will be used to assess the woman-centricity of PROM and PREM development and content validation studies. COSMIN standards of good psychometric properties will be used to evaluate the validity and reliability of the identified instruments.

ETHICS AND DISSEMINATION

Ethical permission for this research is not required. The findings of this research will be submitted for publication in an international, peer-reviewed journal. Abstracts for national and international conference presentations will also be submitted. The proposed maternity PROMs and PREMs database will be freely accessible online, and developed with consumer input to ensure its usefulness to a range of maternity care stakeholders.

The ICECAP-A instrument for capabilities: assessment of construct validity and test-retest reliability in a general Dutch population

PURPOSE

The ICEpop CAPability measure for Adults (ICECAP-A) assesses five capabilities that are important to one's well-being. The instrument might be an important addition to generic health questionnaires when evaluating quality of life extending beyond health. This study aimed to conduct a psychometric assessment of the Dutch translation of the ICECAP-A.

METHODS

Construct validity of the instrument was assessed in two ways. First, by measuring correlations with the EQ-5D-5L questionnaire and a measure of self-efficacy and, second, by investigating the ability to distinguish between groups known to differ on the construct the ICECAP-A means to capture. Additionally, test-retest reliability was evaluated.

RESULTS

In total, 1002 participants representative of the general Dutch population completed an online survey. For test-retest reliability, 252 participants completed the same questionnaire 2 weeks later. The ICECAP-A indicated moderate to strong correlations with the EQ-5D-5L and a strong correlation with self-efficacy. Furthermore, it was capable of differentiating known groups. Moreover, results indicated adequate test-retest reliability with an intraclass correlation coefficient of 0.79.

CONCLUSION

In summary, results suggest adequate test-retest reliability and construct validity and indicate that the ICECAP-A might be of added value, especially when considering areas outside of the traditional health intervention model.

Outpatient Foley Catheter for Induction of Labor in Nulliparous Women: A Randomized Controlled Trial

OBJECTIVE

To assess whether outpatient cervical ripening with a transcervical Foley catheter in nulliparous women undergoing elective labor induction shortens the time from admission to delivery.

METHODS

We performed a randomized controlled trial of patients with singleton pregnancies undergoing elective labor induction at 39 weeks of gestation or more with a modified Bishop score less than 5. Women were randomized 1:1 to outpatient or inpatient transcervical Foley. In the outpatient group, the Foley was inserted the day before admission for scheduled induction; insertion was performed at scheduled admission in the inpatient group. The primary outcome was duration of time from admission to the labor and delivery unit to delivery. With 80% power and a two-sided α of 0.05, a sample size of 126 was estimated to detect at least a 5-hour mean difference in time from admission to delivery between groups from a baseline duration of 19±10 hours.

RESULTS

From May 2018 to October 2019, 126 women were randomized, 63 in each group. Baseline characteristics were balanced between groups, except that body mass index (31±5.4 vs 34±7.5, P=.01) and group B streptococcus colonization (31% vs 54%, P=.01) were lower in the outpatient group. The time from admission to delivery was shorter in the outpatient group (17.4±7.4 vs 21.7±9.1 hours, P<.01, mean difference 4.3 hours, 95% CI 1.3-7.2). Admissions before scheduled induction were higher in the outpatient group (22% vs 5%, relative risk [RR] 4.7, 95% CI 1.4-15.4, P<.01), as was median modified Bishop score on admission (3 vs 1, P<.01). Cesarean delivery (24% vs 32%, RR 0.8, 95% CI 0.4-1.3, P=.32) and chorioamnionitis (22% vs 13%, RR 1.8, 95% CI 0.8-3.9, P=.16) were not significantly different between groups.

CONCLUSION

In nulliparous patients undergoing elective labor induction at term, outpatient cervical ripening with a transcervical Foley catheter reduced the time from admission to delivery.

Challenges in economic evaluations in obstetric care: a scoping review and expert opinion

OBJECTIVE

The aim of this study is to identify items of economic evaluation guidelines that are frequently not complied within obstetric economic evaluations and to search for reasons for non-adherence.

DESIGN

Scoping review and qualitative study.

SETTING

Literature on economic evaluations in obstetric care and interviews with experts.

POPULATION OR SAMPLE

The sample included 229 scientific articles and five experts.

METHODS

A systematic literature search was performed. All types of literature about economic evaluations in obstetric care were included. The adherence to guidelines was assessed and articles were qualitatively analysed on additional information about reasons for non-adherence. Issues that arose from the scoping review were discussed with experts.

MAIN OUTCOME MEASURES

Adherence to guideline items of the included economic evaluations studies. Analytical themes describing reasons for non-adherence, resulting from qualitative analysis of articles and interviews with experts.

RESULTS

A total of 184 economic evaluations and 45 other type of articles were included. Guideline items frequently not complied with were time horizon, type of economic evaluation and effect measure. Reasons for non-adherence had to do with paucity of long-term health data and assessing and combining outcomes for mother and child resulting from obstetric interventions.

CONCLUSIONS

This study identified items of guidelines that are frequently not complied with and the reasons behind this. The results are a starting point for a broad consensus building on how to deal with these challenges that can result in special guidance for the conduct of economic evaluations in obstetric care.

TWEETABLE ABSTRACT

Non-adherence to guidelines in obstetric economic evaluation studies: the difficulties in detail.

Methodological development of tools to measure how women are treated during facility-based childbirth in four countries: labor observation and community survey

Background

Efforts to improve maternal health are increasingly focused on improving the quality of care provided to women at health facilities, including the promotion of respectful care and eliminating mistreatment of women during childbirth. A WHO-led multi-country research project aims to develop and validate two tools (labor observation and community survey) to measure how women are treated during facility-based childbirth. This paper describes the development process for these measurement tools, and how they were implemented in a multi-country study (Ghana, Guinea, Myanmar and Nigeria).

Methods

An iterative mixed-methods approach was used to develop two measurement tools. Methodological development was conducted in four steps: (1) initial tool development; (2) validity testing, item adjustment and piloting of paper-based tools; (3) conversion to digital, tablet-based tools; and (4) data collection and analysis. These steps included systematic reviews, primary qualitative research, mapping of existing tools, item consolidation, peer review by key stakeholders and piloting.

Results

The development, structure, administration format, and implementation of the labor observation and community survey tools are described. For the labor observations, a total of 2016 women participated: 408 in Nigeria, 682 in Guinea, and 926 in Ghana. For the community survey, a total of 2672 women participated: 561 in Nigeria, 644 in Guinea, 836 in Ghana, and 631 in Myanmar. Of the 2016 women who participated in the labor observations, 1536 women (76.2%) also participated in the community survey and have linked data: 779 in Ghana, 425 in Guinea, and 332 in Nigeria.

Conclusions

An important step to improve the quality of maternity care is to understand the magnitude and burden of mistreatment across contexts. Researchers and healthcare providers in maternal health are encouraged to use and implement these tools, to inform the development of more women-centered, respectful maternity healthcare services. By measuring the prevalence of mistreatment of women during childbirth, we will be able to design and implement programs and policies to transform maternity services.

Interrater reliability of the Saint-Anne Dargassies Scale in assessing the neurological patterns of healthy preterm newborns

Abstract Objectives: to assess the interrater reliability of the Saint-Anne Dargassies Scale in assessing neurological patterns of healthy preterm newborns. Methods: twenty preterm newborns met the inclusion criteria for participation in this prospective study. The neurologic examination was performed using the Saint-Anne Dargassies Scale, showing normal serial cranial ultrasound examination. In order to test the reliability, the study was structured as follows: group I (rater 1/physiotherapist; rater 2/neonatologist); group II (rater 3/physiotherapist; rater 4/child neurologist) and the gold standard (expert and professor in pediatric neurology). Results: high interrater agreement was observed between groups I - II compared with the gold standard in assessing postural pattern (p<0.01). Regarding the assessment ofprimitive reflexes, greater agreement was observed in the evaluation of palmar grasp reflex and Moro reflex (p< 0.01) for group I compared with the gold standard. An analysis of tone demonstrated heterogeneous agreement, without compromising the reliability of the scale. The probability of equality between measurements of head circumference in the two groups, compared with the gold standard, was observed. Conclusions: the Saint-Anne Dargassies Scale demonstrated high reliability and homogeneity with significant power of reproducibility and may be capable to identify preterm newborns suspected of having neurological deficits.

Measuring women's childbirth experiences: a systematic review for identification and analysis of validated instruments

BACKGROUND

Women's childbirth experience can have immediate as well as long-term positive or negative effects on their life, well-being and health. When evaluating and drawing conclusions from research results, women's experiences of childbirth should be one aspect to consider. Researchers and clinicians need help in finding and selecting the most suitable instrument for their purpose. The aim of this study was therefore to systematically identify and present validated instruments measuring women's childbirth experience.

METHODS

A systematic review was conducted in January 2016 with a comprehensive search in the bibliographic databases PubMed, CINAHL, Scopus, The Cochrane Library and PsycINFO. Included instruments measured women's childbirth experiences. Papers were assessed independently by two reviewers for inclusion, and quality assessment of included instruments was made by two reviewers independently and in pairs using Terwee et al's criteria for evaluation of psychometric properties.

RESULTS

In total 5189 citations were screened, of which 5106 were excluded by title and abstract. Eighty-three full-text papers were reviewed, and 37 papers were excluded, resulting in 46 included papers representing 36 instruments. These instruments demonstrated a wide range in purpose and content as well as in the quality of psychometric properties.

CONCLUSIONS

This systematic review provides an overview of existing instruments measuring women's childbirth experiences and can support researchers to identify appropriate instruments to be used, and maybe adapted, in their specific contexts and research purpose.

Group based prenatal care in a low-and high risk population in the Netherlands: a study protocol for a stepped wedge cluster randomized controlled trial

BACKGROUND

CenteringPregnancy (CP) is a multifaceted group based care-model integrated in routine prenatal care, combining health assessment, education, and support. CP has shown some positive results on perinatal outcomes. However, the effects are less obvious when limited to the results of randomized controlled trials: as there are few trials and there is a variation in reported outcomes. Furthermore, former research was mostly conducted in the United States of America and in specific (often high risk) populations. Our study aims to evaluate the effects of CP in the Netherlands in a general population of pregnant women (low and high risk). Furthermore we aim to explore the mechanisms leading to the eventual effects by measuring potential mediating factors.

DESIGN

We will perform a stepped wedge cluster randomized controlled trial, in a Western region in the Netherlands. Inclusion criteria are <24 weeks of gestation and able to communicate in Dutch (with assistance). Women in the control period will receive individual care, women in the intervention period (starting at the randomized time-point) will be offered the choice between individual care or CP. Primary outcomes are maternal and neonatal morbidity, retrieved from a national routine database. Secondary outcomes are health behavior, psychosocial outcomes, satisfaction, health care utilization and process outcomes, collected through self-administered questionnaires, group-evaluations and individual interviews. We will conduct intention-to-treat analyses. Also a per protocol analysis will be performed comparing the three subgroups: control group, CP-participants and non-CP-participants, using multilevel techniques to account for clustering effects.

DISCUSSION

This study contributes to the evidence regarding the effect of CP and gives a first indication of the effect and implementation of CP in both low and high-risk pregnancies in a high-income Western society other than the USA. Also, measuring factors that are hypothesized to mediate the effect of CP will enable to explain the mechanisms that lead to effects on maternal and neonatal outcomes.
