The complexity of postpartum mental health and illness: a critical realist study

Critical Realism in Symptom Science - A Scoping Review

There has been an increasing interest in research positioned within critical realism (CR). This analysis aimed to determine how CR has been applied in symptom science through a scoping review of the literature. Fifty-two articles were identified through searches in seven databases and search engines, and grey literature. Quantitative and qualitative analyses were performed using Excel and ATLAS.ti 8.0. Review findings indicate that CR has been used to examine two key aspects of symptoms - symptom experiences and symptom interventions. The details of how CR was operationalized are presented. This first scoping review highlights how a critical realist lens would help examine individual and contextual factors that influence symptom experiences, response to interventions, and outcomes.

The Effects of Perceived Social Support on Postpartum Anxiety: A Moderated Mediation Model

PURPOSE

Previous literature showed that perceived social support, self-esteem and optimism all played critical roles in the developing of postpartum anxiety. However, the mechanisms of influence were still unclear. This study aimed to explore the underlying mechanism of the relationship among perceived social support, self-esteem, optimism and postpartum anxiety.

METHOD

756 women within one year after childbirth were surveyed using the Perceived Social Support Scale, Self-Assessment of Anxiety Scale, Self-Esteem Scale and Life Orientation Test Questionnaire. Pearson correlation analyses were performed to determine the direction and size of the all variables. The mediation model and the moderated mediation model were performed using the PROCESS macro.

RESULTS

Postpartum anxiety negatively correlated with perceived social support, self-esteem and optimism. A significant positive relationship existed among perceived social support, self-esteem and optimism. Self-esteem played a mediating role in the association between perceived social support and postpartum anxiety, with a mediating effect value of - 0.23. Optimism moderated the mediating process by which perceived social support affected postpartum anxiety via self-esteem. At the three levels of optimism (mean minus 1 SD, mean and mean plus 1 SD), the mediating effect values of self-esteem in the relationship between perceived social support and postpartum anxiety tended to diminish.

CONCLUSION

Self-esteem partially mediated the relationship between perceived social support and postnatal anxiety, and this mediating process was moderated by optimism.

Characteristics and changes in characteristics of women and babies admitted to residential parenting services in New South Wales, Australia in the first year following birth: a population-based data linkage study 2000-2012

OBJECTIVE

To examine the characteristics of women and babies admitted to the residential parenting services (RPS) of Tresillian and Karitane in the first year following birth.

DESIGN

A linked population data cohort study was undertaken for the years 2000-2012.

SETTING

New South Wales (NSW), Australia.

PARTICIPANTS

All women giving birth and babies born in NSW were compared with those admitted to RPS.

RESULTS

During the time period there were a total of 1 097 762 births (2000-2012) in NSW and 32 991 admissions to RPS. Women in cohort 1: (those admitted to RPS) were older at the time of birth, more likely to be admitted as a private patient at the time of birth, be born in Australia and be having their first baby compared with women in cohort 2 (those not admitted to an RPS). Women admitted to RPS experienced more birth intervention (induction, instrumental birth, caesarean section), had more multiple births and were more likely to have a male infant. Their babies were also more likely to be resuscitated and have experienced birth trauma to the scalp. Between 2000 and 2012 the average age of women in the RPS increased by nearly 2 years; their infants were older on admission and women were less likely to smoke. Over the time period there was a drop in the numbers of women admitted to RPS having a normal vaginal birth and an increase in women having an instrumental birth.

CONCLUSION

Women who access RPS in the first year after birth are more socially advantaged and have higher birth intervention than those who do not, due in part to higher numbers birthing in the private sector where intervention rates are high. The rise in women admitted to RPS (2000-2012) who have had instrumental births is intriguing as overall rates did not increase.

Philosophy and quality? TAPUPASM as an approach to rigour in critical realist research

BACKGROUND

Philosophical principles should guide how research is designed, conducted and appraised. The more traditional and commonly used approaches to positivist (validity and generalisability) or interpretivist (trustworthiness) research do not necessarily complement the philosophical principles of post-positivist critical realism.

AIMS

To discuss an approach to ensuring scientific rigour in post-positivist critical realist research using an enhanced version of the quality assurance model, TAPUPAS, that has an additional criterion: modified objectivity.

DISCUSSION

The authors present examples of the quality framework TAPUPASM in the planning, design, conduct and dissemination of a realist research study. These strategies include choices about the collection and analysis of data, as well as how to disseminate findings using methods other than traditional academic approaches. They also provide a practical example of how they used TAPUPASM to ensure rigour in a critical realist ethnographic study in pre-registration nurse education.

CONCLUSION

TAPUPASM provides a framework for quality in post-positivist critical realist research.

IMPLICATIONS FOR PRACTICE

Nurse researchers can use the strategies provided to plan, design, conduct and disseminate critical realist research.

Exploring reasoning mechanisms in ward rounds: a critical realist multiple case study

BACKGROUND

Ward rounds are an important and ubiquitous element of hospital care with a history extending well over a century. Although originally intended as a means of educating medical trainees and junior doctors, over time they have become focused on supporting clinical practice. Surprisingly, given their ubiquity and importance, they are under-researched and inadequately understood. This study aims to contribute knowledge in human reasoning within medical teams, meeting a pressing need for research concerning the reasoning occurring in rounds.

METHODS

The research reported here aimed to improve the understanding of ward round reasoning by conducting a critical realist case study exploring the collaborative group reasoning mechanisms in the ward rounds of two hospitals in Victoria, Australia. The data collection involved observing rounds, interviewing medical practitioners and holding focus group meetings.

RESULTS

Nine group reasoning mechanisms concerning sharing, agreeing and recording information in the categories of information accumulation, sense-making and decision-making were identified, together forming a program theory of ward round reasoning. In addition, themes spanning across mechanisms were identified, further explaining ward round reasoning and suggesting avenues for future exploration. Themes included the use of various criteria, tensions involving mechanisms, time factors, medical roles and hierarchies.

CONCLUSIONS

This paper contributes to the literature by representing rounds in a manner that strengthens understanding of the form of the group reasoning occurring within, thus supporting theory-based evaluation strategies, redesigned practices and training enhancements.

Depressive Symptoms and Influencing Factors in Low-Risk Mothers

INTRODUCTION

Depressive symptoms burden not only postpartum women, but can also compromise partner relationships and mother-infant interactions. With approximately 15% of women affected by perinatal mood and anxiety disorders (PMADs) each year, maternity care providers must be sensitive to personal characteristics and complaints that influence women's potential to develop postpartum depression (PPD). The purpose of the study was to identify personal characteristics and modifiable factors associated with depressive symptoms in low-risk postpartum women.

METHODS

A descriptive, correlational design was used to identify predictors of depressive symptoms among mothers who were considered to be at low risk for PPD. Self-report data related to mood, stress, sleep disturbance, and fatigue were collected near the sixth week post-delivery from women (N = 62) in a southern US state.

RESULTS

The levels of stress and reports of sleep disturbance approached clinical concern in the low-risk sample (n = 62), in addition to being positively correlated depressive symptoms. Cesarean delivery was also associated with increased depressive symptoms and predictive of depression symptoms when combined with perceived chronic stress, sleep disturbance, and fatigue.

DISCUSSION

The findings underscore the importance of assessing maternal mental health and adjustment during the postpartum period. While some mothers may not report depressive symptoms at post-delivery visits, they may be experiencing symptoms that predispose them to a mood disorder. Using a more holistic approach to postpartum care, with concern for both physical and mental well-being, may be a necessary shift to promote health in new mothers and families.

A systematic review, evidence synthesis and meta-analysis of quantitative and qualitative studies evaluating the clinical effectiveness, the cost-effectiveness, safety and acceptability of interventions to prevent postnatal depression

BACKGROUND

Postnatal depression (PND) is a major depressive disorder in the year following childbirth, which impacts on women, their infants and their families. A range of interventions has been developed to prevent PND.

OBJECTIVES

To (1) evaluate the clinical effectiveness, cost-effectiveness, acceptability and safety of antenatal and postnatal interventions for pregnant and postnatal women to prevent PND; (2) apply rigorous methods of systematic reviewing of quantitative and qualitative studies, evidence synthesis and decision-analytic modelling to evaluate the preventive impact on women, their infants and their families; and (3) estimate cost-effectiveness.

DATA SOURCES

We searched MEDLINE, EMBASE, Science Citation Index and other databases (from inception to July 2013) in December 2012, and we were updated by electronic alerts until July 2013.

REVIEW METHODS

Two reviewers independently screened titles and abstracts with consensus agreement. We undertook quality assessment. All universal, selective and indicated preventive interventions for pregnant women and women in the first 6 postnatal weeks were included. All outcomes were included, focusing on the Edinburgh Postnatal Depression Scale (EPDS), diagnostic instruments and infant outcomes. The quantitative evidence was synthesised using network meta-analyses (NMAs). A mathematical model was constructed to explore the cost-effectiveness of interventions contained within the NMA for EPDS values.

RESULTS

From 3072 records identified, 122 papers (86 trials) were included in the quantitative review. From 2152 records, 56 papers (44 studies) were included in the qualitative review. The results were inconclusive. The most beneficial interventions appeared to be midwifery redesigned postnatal care [as shown by the mean 12-month EPDS score difference of -1.43 (95% credible interval -4.00 to 1.36)], person-centred approach (PCA)-based and cognitive-behavioural therapy (CBT)-based intervention (universal), interpersonal psychotherapy (IPT)-based intervention and education on preparing for parenting (selective), promoting parent-infant interaction, peer support, IPT-based intervention and PCA-based and CBT-based intervention (indicated). Women valued seeing the same health worker, the involvement of partners and access to several visits from a midwife or health visitor trained in person-centred or cognitive-behavioural approaches. The most cost-effective interventions were estimated to be midwifery redesigned postnatal care (universal), PCA-based intervention (indicated) and IPT-based intervention in the sensitivity analysis (indicated), although there was considerable uncertainty. Expected value of partial perfect information (EVPPI) for efficacy data was in excess of £150M for each population. Given the EVPPI values, future trials assessing the relative efficacies of promising interventions appears to represent value for money.

LIMITATIONS

In the NMAs, some trials were omitted because they could not be connected to the main network of evidence or did not provide EPDS scores. This may have introduced reporting or selection bias. No adjustment was made for the lack of quality of some trials. Although we appraised a very large number of studies, much of the evidence was inconclusive.

CONCLUSIONS

Interventions warrant replication within randomised controlled trials (RCTs). Several interventions appear to be cost-effective relative to usual care, but this is subject to considerable uncertainty.

FUTURE WORK RECOMMENDATIONS

Several interventions appear to be cost-effective relative to usual care, but this is subject to considerable uncertainty. Future research conducting RCTs to establish which interventions are most clinically effective and cost-effective should be considered.

Assessment and Care of Childbearing Women With Severe and Persistent Mental Illness

Severe and persistent mental illness (SPMI) refers to complex mood disorders that include major depressive disorder with or without psychosis; severe anxiety disorders resistant to treatment; affective psychotic disorders including bipolar affective disorder, schizophrenia, and schizoaffective disorder; and other nonaffective subtypes of schizophrenia. SPMIs affect 1 in 17 people and are among the leading causes of disability and impaired health-related quality of life in the United States. Caring for childbearing women with preexisting SPMI can be challenging for maternal-child health clinicians. This article provides an overview of SPMI during pregnancy and challenges for clinicians, including early identification, accuracy of diagnoses, and appropriate management through care coordination among an interdisciplinary team that includes obstetric providers, psychiatrists, nurses, and others.

Mothering and anxiety: Social support and competence as mitigating factors for first-time mothers

This study investigated anxiety as a phenomenon distinct from depression and evaluated several variables that influence anxiety in first-time mothers. This explored the relationship between maternal sense of competence (both of mothering and efficacy) and perceived social support (from family, friends, and significant others) and first-time mothers' postpartum anxiety, when depression, socioeconomic status (SES), and marital status were controlled for. The population studied were 86 first-time mothers made up of women with children 24 months or younger in two populations of Kentucky and Michigan. The constructs of maternal sense of competence and perceived social support were found to be significant in explaining first-time mothers' anxiety. The study concluded that a combined association of perceived social support and maternal sense of competence were associated with a 34% (change in R-squared = .339) decrease of a first-time mothers' anxiety. However, not all types of social support, or maternal competence appeared to be equally important with regards to maternal anxiety: social support from friends and family and maternal sense of competence in regard to productivity appeared to be most significant. Lastly, some recommendations for health practitioners who work with mothers are provided.

Enhancing reciprocal partner support to prevent perinatal depression and anxiety: a Delphi consensus study

BACKGROUND

Systematic reviews have established that partner support protects against perinatal mood problems. It is therefore a key target for interventions designed to prevent maternal and paternal depression and anxiety. Nonetheless, the extant literature is yet to be translated into specific actions that parents can implement. Prevention efforts aiming to facilitate reciprocal partner support within the couple dyad need to provide specific guidance on how partners can support one another to reduce their vulnerability to perinatal depression and anxiety.

METHOD

Two panels of experts in perinatal mental health (21 consumer advocates and 39 professionals) participated in a Delphi consensus study to establish how partners can support one another to reduce their risk of developing depression and anxiety during pregnancy and the postpartum period.

RESULTS

A total of 214 recommendations on how partners can support each other were endorsed by at least 80 % of both panels as important or essential in reducing the risk of perinatal depression and anxiety. The recommendations were grouped under the following categories: becoming a parent, supporting each other through pregnancy and childbirth, communication, conflict, division of labor, practical support, emotional support, emotional closeness, sexual satisfaction, using alcohol and drugs, encouraging self-care, developing acceptance, and help-seeking.

CONCLUSION

This study established consensus between consumers and professionals in order to produce a set of guidelines on how partners can support each other to prevent depression and anxiety during pregnancy and following childbirth. It is hoped that these guidelines will inform the development of perinatal depression and anxiety prevention efforts.

An ethnographic investigation of the maternity healthcare experience of immigrants in rural and urban Alberta, Canada

Background

Canada is among the top immigrant-receiving nations in the world. Immigrant populations may face structural and individual barriers in the access to and navigation of healthcare services in a new country. The aims of the study were to (1) generate new understanding of the processes that perpetuate immigrant disadvantages in maternity healthcare, and (2) devise potential interventions that might improve maternity experiences and outcomes for immigrant women in Canada.

Methods

The study utilized a qualitative research approach that focused on ethnographic research design and data analysis contextualized within theories of organizational behaviour and critical realism. Data were collected over 2.5 years using focus groups and in-depth semistructured interviews with immigrant women (n = 34), healthcare providers (n = 29), and social service providers (n = 23) in a Canadian province. Purposive samples of each subgroup were generated, and recruitment and data collection – including interpretation and verification of translations – were facilitated through the hiring of community researchers and collaborations with key informants.

Results

The findings indicate that (a) communication difficulties, (b) lack of information, (c) lack of social support (isolation), (d) cultural beliefs, e) inadequate healthcare services, and (f) cost of medicine/services represent potential barriers to the access to and navigation of maternity services by immigrant women in Canada. Having successfully accessed and navigated services, immigrant women often face additional challenges that influence their level of satisfaction and quality of care, such as lack of understanding of the informed consent process, lack of regard by professionals for confidential patient information, short consultation times, short hospital stays, perceived discrimination/stereotyping, and culture shock.

Conclusions

Although health service organizations and policies strive for universality and equality in service provision, personal and organizational barriers can limit care access, adequacy, and acceptability for immigrant women. A holistic healthcare approach must include health informational packages available in different languages/media. Health care professionals who care for diverse populations must be provided with training in cultural competence, and monitoring and evaluation programs to ameliorate personal and systemic discrimination.

Perinatal Music Therapy and Antenatal Music Classes: Principles, Mechanisms, and Benefits

Antenatal music activities are in the ascendant. Regarding evidence-based research, the article advocates 5 main aims: music therapeutic control of pre- and perinatal stress, anxiety, and depression; music-related mental and physical birth preparation comprising cognitive adjustment, emotional regulation, physical activity, relaxation and pain management, and social inclusion; music-associated bonding and self-efficacy; prenatal sound stimulation to trigger learning processes, pedagogical priming and brain maturation; music activities to facilitate the child's acculturation and adaptive self-regulation. Underlying mechanisms such as neuroplasticity help to understand the multifaceted effects of music in pre- and perinatal care. Individual conditions and features of the mother and her child have to be taken into account and music interventions to be harmonized with complementary perinatal programs.

Postpartum depression in refugee and asylum-seeking women in Canada: A critical health psychology perspective

Canada has one of the world's largest refugee resettlement programs in the world. Just over 48 percent of Canadian refugees are women, with many of them of childbearing age and pregnant. Refugee and asylum-seeking women in Canada face a five times greater risk of developing postpartum depression than Canadian-born women. Mainstream psychological approaches to postpartum depression emphasize individual-level risk factors (e.g. hormones, thoughts, emotions) and individualized treatments (e.g. psychotherapy, medication). This conceptualization is problematic when applied to refugee and asylum-seeking women because it fails to acknowledge the migrant experience and the unique set of circumstances from which these women have come. The present theoretical article explores some of the consequences of applying this psychiatric label to the distress experienced by refugee and asylum-seeking women and presents an alternative way of conceptualizing and alleviating this distress.

A qualitative meta-synthesis and theory of postpartum depression

To synthesize existing qualitative literature on the first-hand experiences of women suffering from postpartum depression (PPD), to uncover potential common themes, a meta-synthesis of 12 qualitative studies using Noblit and Hare's 7-phase model of meta-ethnography was used. Four themes were discovered: crushed maternal role expectation, going into hiding, loss of sense of self, intense feelings of vulnerability, plus practical life concerns. A preliminary theory of PPD as a 4-step process is proposed, based on the relationships between the themes in this meta-synthesis. This 4-step process is compared and contrasted with Cheryl Tatano Beck's 4-stage theory of PPD "Teetering on the Edge". This meta-synthesis and theory offers a significant contribution to the literature in helping identify PPD distinctly from depression outside of the postpartum period, and deserves further study.
