Experiences of using the Edinburgh Postnatal Depression Scale in the context of antenatal care for Aboriginal mothers: Women and midwives' perspectives.

PROBLEM: Routine administration of the Edinburgh Postnatal Depression Scale (EPDS) is intended to promote early detection and preventative support for those who may be at risk of perinatal depression and anxiety. The cultural suitability of the EPDS has not been validated in the Aboriginal Australian context. BACKGROUND: Marked differences in health outcomes and service access between Australian Aboriginal and non-Aboriginal women and infants continue to exist. AIM: This study aimed to explore the cultural validity of the EPDS through understanding the experiences of Aboriginal women and midwives. METHODS: Qualitative data was drawn from semi-structured interviews/yarns with 13 Perth-based Aboriginal antenatal women and 10 non-Aboriginal midwives. FINDINGS: Utilising a grounded theory approach, thematic analysis of verbatim transcripts revealed that, surprisingly, women expressed generally favourable views of the EPDS, especially when the relationships between women and midwives were focused on. Midwives, however, expressed reservations about administering the EPDS and used the EPDS as a conversation-starter rather than as a standardised, standalone tool. DISCUSSION: In attempt to reconcile conflicting perspectives, analysis of recordings extended to evaluate micro-processes in the interviews. At the process level, it was clear that demand characteristics operated in some interviews, including socially desirable response biases, demand biases and acquiescent response styles. CONCLUSION: This highlights the need for researchers and clinicians to be trained in non-leading interview questioning techniques and in yarning methodology. Researchers and clinicians should also be aware of the cognitive biases and demand characteristics that may influence responding, likely perpetuated by dominant forces of a colonised society.

A systematic review of EPDS cultural suitability with Indigenous mothers: a global perspective.

The Edinburgh Postnatal Depression Scale (EPDS) is used extensively as the "gold standard" perinatal depression and anxiety screening tool. This study contributes to an emerging discussion about the tool's shortcomings, specifically around cultural suitability for use with Indigenous women. A systematic search was conducted in ProQuest, PsycINFO, MEDLINE (Web of Science), PubMed, Scopus, Informit, and CINAHL research databases, and grey literature. The quality of the body of evidence was assessed using the NHMRC Level of Evidence framework. Three studies supported the cultural validation of the EPDS with Indigenous groups in Canada (n = 2) and the USA (n = 1). The remaining eleven Australian studies demonstrated that cultural concerns were suggested by either Indigenous mothers, healthcare professionals (Indigenous and non-Indigenous), or both, though cultural concerns were more weighted from the perspectives of healthcare professionals. The quality of the evidence was not strong, and thus, there is a critical and urgent need for targeted research in this area. This review identified and recommended Indigenous-specific methodologies that can be adopted for more trustworthy, culturally safe, and effective research in this area. Given that the EPDS is currently considered gold standard in routine perinatal mental health screening practice in countries around the world, these findings raise significant concerns. Using culturally relevant research methodologies, such as the use of mixed-methods design, could lay stronger groundwork for further investigation of the broader utility and cultural relevance of the tool.

Research protocol for the exploration of experiences of Aboriginal Australian mothers and healthcare professionals when using the Edinburgh Postnatal Depression Scale: a process-oriented validation study using triangulated participatory mixed methods.

INTRODUCTION: Adopting a process-oriented framework for test validation can help to establish whether this tool has the potential to be an acceptable, valid and reliable indicator of depression for mothers and mothers-to-be. This mixed-methods research protocol seeks to explore the views and experiences of Aboriginal mothers and healthcare professionals in relation to the Edinburgh Postnatal Depression Scale (EPDS), and is intended to highlight potential barriers in perinatal mental health conceptualisation, engagement and response style. METHODS AND ANALYSIS: Thematic analysis will be applied to interview transcripts of Aboriginal Australian mothers (n=6+) and healthcare professionals (n=6+) to identify key themes. The process-focused validation model will use narratives about experiences of using the EPDS as the priority point of analysis. Item-level data and process-level (experience) data are key phenomenological data. The interview-based narratives will be then compared with EPDS scores to check for points of congruence and divergence. This will be done at two time points, antenatally and postnatally, to assess changes in assessment processes and perceptions. Bridging evidence-based research with clinical practice in an Aboriginal Australian context will be facilitated by an investigation of the perceived cultural relevance and likely clinical effectiveness of EPDS. Such evidence is critical to understanding whether the EPDS fulfils its intended purpose. The guiding principles in designing this research protocol is to benefit the well-being of young Aboriginal families and communities through partnership with Aboriginal women. ETHICS AND DISSEMINATION: Ethics approval was obtained from Human Research Ethics Committee of Murdoch University and from Western Australian Aboriginal Health Ethics Committee (WAAHEC). Participating healthcare sites and services have provided letters of support. Results of this study will be submitted for publication in a peer-reviewed journal.
