Being alone and expectations lost: a critical realist study of maternal depression in South Western Sydney

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.

Females undergo selection too

Extending Campbell's (1999) staying alive theory (SAT) beyond aggression, we reviewed evidence that females are more self-protective than males. Many commentators provided additional supporting data. Sex differences in life-history adaptations, in the optimal relation between survival and reproduction, and in the mechanisms underlying trade-offs involved with self-protection remain important topics with numerous opportunities for improved understanding.

Can the Healthy Start Risk Screen Predict Perinatal Depressive Symptoms among High-Risk Women?

OBJECTIVES

Early detection of depression in at-risk populations is critical for ensuring better maternal and child health outcomes. This study assessed whether Healthy Start Prenatal Risk Screening (HSPRS) could predict depressive symptoms in women enrolled in a Healthy Start (HS) program in under-resourced, high-risk communities of Hillsborough County.

METHODS

Data from HS participants were included for those who were evaluated using the HSPRS and the Edinburgh Postnatal Depression Scale (EPDS). A correlation analysis determined if the HSPRS score was associated with a positive EPDS screen, and HSPRS questions related to the participants psychosocial environment were assessed individually to determine their predictive potential. The crude odds ratio (OR) and adjusted OR (controlling for sociodemographic covariates) were calculated for each question of interest.

RESULTS

A total of 736 women were included, with 122 (16.5%) scoring 14 or greater on the EPDS, indicating probable depression risk. There were significant differences between women at risk for depression compared to those not at risk regarding maternal age (p-value = 0.03) and marital status (p-value = 0.01). There were no significant differences in education, ethnicity, or race. The total HSPRS score had a weak yet significant correlation with the EPDS score (r = 0.14, p-value = 0.0001), and seven individual HSPRS questions were significantly associated with risk for perinatal depression. Conclusions for Practice: By focusing on responses to key HSPRS questions rather than the overall score, women may receive access to much needed services more quickly, thereby reducing the risk for poorer maternal and developmental outcomes.

SIGNIFICANCE

A young maternal age and single marital status have been identified as risk factors for perinatal depression. Additionally, women from racial/ethnic minority groups or low-income populations are more likely to experience depression. Thus, in communities where women exhibit many pre-identified risk factors for perinatal depression, the ability to quickly identify those at the highest risk is imperative. This work indicates that among medically and socially high-risk mothers enrolled in a HS program, the overall HSPRS score was not as predictive of perinatal depression as individual responses to key questions. Attention to these responses could result in women receiving much needed services quicker.

A critical realist evaluation of an integrated care project for vulnerable families in Sydney, Australia

BACKGROUND

Healthy Homes and Neighbourhoods (HHAN) Integrated Care Initiative was established to improve the care of families with complex health and social needs who reside in Sydney Local Health District. HHAN seeks to provide long-term multi-disciplinary care coordination as well as enhance capacity building and promote integrated care. The critical realist study reported here is part of the longitudinal development and evaluation of complex integrated health and social care interventions in Sydney, Australia.

METHODS

We describe the qualitative component of a critical realist pilot case study aimed at exploring, explaining and refining emerging HHAN programme theories in relation to care coordination. Qualitative interviews were undertaken with HHAN clients (n = 12), staff and other stakeholders (n = 21). Interviews and coding used a context (C), mechanism (M) and outcome (O) framework. Inductive, deductive, retroductive and abductive modes of reasoning were used with the CMO heuristic tool to inform the developing programme theory.

RESULTS

The mechanisms underpinning effective engagement of clients by care coordinators included: building trust, leveraging other family, social and organisational relationships, meeting clients on their own terms, demonstrating staff effectiveness as quickly as possible, and client empowerment. Mechanisms for enhancing care integration included knowledge transfer activities and shared learning among collaborators, structural and cultural changes, enhancing mutual respect, co-location of multidisciplinary and/or interagency staff and cultivating faith in positive change among staff.

CONCLUSIONS

Use of a critical realism case study approach served to elucidate the varied influences of contexts and mechanisms on programme outcomes, to highlight what works for whom and in what context. Findings supported the initial programme theory that engagement and trust building with clients, alongside enhanced collaboration and integration of services, improved outcomes for vulnerable families with complex needs. Further research is needed to explore the cost-effectiveness of integrated care initiatives, in view of the long term nature of service provision and the risk of staff burnout.

Refining Program Theory for a Place-Based Integrated Care Initiative in Sydney, Australia

Introduction

The Healthy Homes and Neighbourhoods (HHAN) Integrated Care Program seeks to enhance vulnerable family engagement with health and social services through a care coordination model. Besides servicing families in Sydney, HHAN has also established place-based initiatives (PBIs) in areas of disadvantage such as Redfern. The Redfern PBI co-locates HHAN with housing, drug and alcohol services, and financial and legal services. This integration aims to facilitate service access and multi-agency support for vulnerable families in Redfern. Hence, this study aims to evaluate for whom, when and why HHAN's PBI at Redfern works, or not, and what are its outcomes.

Methods

The project utilises critical realist methodology to undertake a qualitative evaluation of the impact of the PBI on clients, services and the community. Purposive sampling was used to identify 21 participants including HHAN clients, HHAN staff and stakeholders (HHAN partners). In-depth, semi-structured interviews were audio-recorded, transcribed, coded and analysed using a context (C), intervention (I), mechanism (M) outcome (O) (CIMO) approach to abductive analysis.

Results

Five key CIMO configurations of the Redfern PBI emerged - whole-of-family involvement, flexibility, trust, building connections and co-location. Whilst each theory had specific outcomes, overall client outcomes included improved access to services, better outlook, empowerment and engagement with services. Service outcomes included increased collaboration and foundation for integration between HHAN and other services. Negative outcomes included lack of full integration, the risk associated with integration and difficulty evaluating impact.

Conclusion

This study successfully refined the program theory for subsequent use in later implementation of critical realist evaluation studies.

A qualitative insight into the relationship between postpartum depression and body image

Objective: This study qualitatively explored the experience of depression and body image concerns in women diagnosed with depression in the postpartum period.Background: Women's bodies undergo substantial changes during the perinatal period which can impact their body image and mood post-birth.However, it remains unknown how women diagnosed with depression experience their body image in the postpartum period.Methods: Seventeen women in their firstpostpartumyear completed qualitative telephone interviews: seven women diagnosed with depression and ten without depression. Thematic content analysis identified the main themes of the women's narratives: 1) expectations and adjustments to motherhood; 2) mood in response to changing postpartum body; 3) the context of feeling bad about my body; and 4) body letting me down and relationship to mood.Results: Differences in the relationship between body image and mood for postpartum women with depression compared to women without depression were revealed. Other themes seemed to be experienced in the same way by women with and without depression.Conclusion: Poor body image and depressive symptoms appear linked during postpartum. An improved understanding of this association may assist postpartum women to manage negative body image post-birthand prevent the exacerbation of negative emotional health in this period.

Infant temperament and perinatal depressive and anxiety symptoms in Mexican women

AIM

This study explores the association between infant temperament at six months postpartum and pre- and postpartum depressive and anxiety symptoms. The association between infant temperament and stressful life events is also evaluated.

METHOD

A total of 210 Mexican women were assessed during pregnancy (gestational age 32.39 ± 4.01) and at six months postpartum. The instruments used were: Patient Health Questionnaire (PHQ-9), the Anxiety Subscale of the Hopkins Symptoms Checklist (SCL-90R), a short form of Stressful Life Events and The Infant Characteristics Questionnaire, when infants were six months old.

RESULTS

Although a mother's emotional state during pregnancy (depressive and anxiety symptoms and stressful life events) was not associated with difficult infant temperament, it was associated with depressive and anxious symptomatology during the postpartum period. Mothers with prenatal depressive symptoms who remained depressed and mothers who only had depression symptoms during the postpartum period reported having more difficult infants. Likewise, mothers with prenatal anxiety symptoms who maintained anxiety symptoms postpartum and mothers with anxiety symptoms during the postpartum period alone reported having more difficult infants. Comorbidity was found between depressive and anxious postnatal symptomatology in its association with difficult infant temperament.

CONCLUSION

In this study, postpartum depressive and anxiety symptoms played an important role in shaping difficult infant temperament. Comorbidity between the two conditions warrants clinical attention and additional research, since it is related to maternal perception of difficult infant temperament. Psychological interventions are required, since these women may require assistance with emotional adaptation in the transition to motherhood.

A Critical Realist Translational Social Epidemiology Protocol for Concretising and Contextualising a "Theory of Neighbourhood Context, Stress, Depression, and the Developmental Origins of Health and Disease (DOHaD)", Sydney Australia

Background:

We will describe here a translational social epidemiology protocol for confirming a critical realist “Theory of Neighbourhood Context, Stress, Depression, and the Developmental Origins of Health and Disease (DOHaD). The approach will include the concretising and contextualising of the above causal theory into programme theories for child and adolescent interventions that aim to break intergenerational cycles of disadvantage and poor life outcomes. In undertaking this work we seek to advance realist translational methodology within the discipline of applied perinatal and paediatric social epidemiology.

Theory and Methods:

The research settings are in metropolitan Sydney. The design will be a longitudinal, multi-level, mixed method realist evaluation of applied programme interventions that seek to break the intergeneration cycle of social disadvantage and poor child health and developmental outcomes. The programme of research will consist of three components: 1) Operationalisation of the theory and designing of programme initiatives for implementation; 2) Evaluation of the translated programme and implementation theory using Theory of Change and critical realist evaluation; and 3) Theory Testing of realist hypotheses using both intensive and extensive critical realist research methods including realist structural modelling.

Discussion:

The proposed programme of research will assist in translating empirical explanatory theory building to theory driven interventions. The research will be situated in socially disadvantaged regions of Sydney where the local child and family inter-agencies will collaborate to design and implement new initiatives that address significant disparities in childhood development and adolescent outcomes attributed to neighbourhood circumstances, family stress and intergenerational cycles of disadvantage and poor mental health.

War or Peace? How the Subjective Perception of Great Power Interdependence Shapes Preemptive Defensive Aggression

Why do great powers with benign intentions end up fighting each other in wars they do not seek? We utilize an incentivized, two-person "Preemptive Strike Game" (PSG) to explore how the subjective perception of great power interdependence shapes defensive aggression against persons from rival great powers. In Study 1, college students from the United States (N = 115), China (N = 106), and Japan (N = 99) made PSG decisions facing each other. This natural experiment revealed that Chinese and Japanese participants (a) made more preemptive attacks against each other and Americans than against their compatriots, and that (b) greater preexisting perceptions of bilateral competition increased intergroup attack rates. In Study 2, adult Americans (N = 127) watched real CNN expert interviews portraying United States-China economic interdependence as more positive or negative. This randomized experiment revealed that the more positive portrayal reduced preemptive American strikes against Chinese (but not Japanese), while the more negative portrayal amplified American anger about China's rise, increasing preemptive attacks against Chinese. We also found, however, that preemptive strikes were primarily defensive and not offensive. Interventions to reduce defensive aggression and promote great power peace are discussed.

Realist theory construction for a mixed method multilevel study of neighbourhood context and postnatal depression

BACKGROUND

We have recently described a protocol for a study that aims to build a theory of neighbourhood context and postnatal depression. That protocol proposed a critical realist Explanatory Theory Building Method comprising of an: (1) emergent phase, (2) construction phase, and (3) confirmatory phase. A concurrent triangulated mixed method multilevel cross-sectional study design was described. The protocol also described in detail the Theory Construction Phase which will be presented here.

METHODS

The Theory Construction Phase will include: (1) defining stratified levels; (2) analytic resolution; (3) abductive reasoning; (4) comparative analysis (triangulation); (5) retroduction; (6) postulate and proposition development; (7) comparison and assessment of theories; and (8) conceptual frameworks and model development.

THEORY CONSTRUCTION

The stratified levels of analysis in this study were predominantly social and psychological. The abductive analysis used the theoretical frames of: Stress Process; Social Isolation; Social Exclusion; Social Services; Social Capital, Acculturation Theory and Global-economic level mechanisms. Realist propositions are presented for each analysis of triangulated data. Inference to best explanation is used to assess and compare theories. A conceptual framework of maternal depression, stress and context is presented that includes examples of mechanisms at psychological, social, cultural and global-economic levels. Stress was identified as a necessary mechanism that has the tendency to cause several outcomes including depression, anxiety, and health harming behaviours. The conceptual framework subsequently included conditional mechanisms identified through the retroduction including the stressors of isolation and expectations and buffers of social support and trust.

CONCLUSION

The meta-theory of critical realism is used here to generate and construct social epidemiological theory using stratified ontology and both abductive and retroductive analysis. The findings will be applied to the development of a middle range theory and subsequent programme theory for local perinatal child and family interventions.
