ABSTRACT
INTRODUCTION: The purpose of this study was to explore the reliability and construct validity of the EPDS-US. METHODS: To enhance the perinatal mental health screen, we adapted the Edinburgh Postnatal Depression Screen (EPDS) for application in the United States, and evaluated reliability and construct validity of the EPDS-US in a sample of 100 postpartum individuals. We explored reliability by estimating internal consistency of the scale and evaluating concurrent validity with correlations to the Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder Assessment (GAD-7); and construct validity using factor analysis and discriminant validity with correlations to the Perceived Stress Scale (PSS). RESULTS: We present both a one-factor (Cronbach's alpha of 0.83) and two-factor model consisting of depressive (Cronbach's alpha 0.76) and anxiety symptoms (Cronbach's alpha 0.78) of the EPDS-US. Related to discriminant validity, the EPDS-US and PSS exhibited a moderate correlation of 0.71. For measures of concurrent validity, correlations with the PHQ-9 and GAD-7 were moderate; 0.63 and 0.68, respectively. CONCLUSION: The EPDS-US was adapted to enhance the perinatal mental health screening experience for populations in the US while maintaining the reliability and validity of the original Edinburgh Postnatal Depression Scale. These findings contribute to the evidence of reliability and validity of the EPDS-US in perinatal populations in the United States; presenting initial evidence supporting construct validity and concurrent validity of this newly adapted 10-item scale.

Objective: To evaluate the validity of the Edinburgh Postnatal Depression Scale (EPDS) for screening during the perinatal period in the United States and concerns regarding its acceptability and performance. Methods: We conducted a systematic search in OVID MEDLINE, EMBASE (OVID), Cumulative Index to Nursing and Allied Health Literature (CINAHL), and PsycInfo (EBSCO) for articles published from inception of the database through February 2023. We included primary quantitative and qualitative studies on the validation of the EPDS in the United States and identified 880 articles of which 9 met criteria for inclusion. We extracted data related to aim, study population, setting, methods, outcomes, and key findings from each study into a table based on Joanna Briggs Institute (JBI) Scoping Review Guidelines. Results: We found no evidence that the original wording of the EPDS, which was developed in the United Kingdom, was adapted before validation in the United States. Conclusion: Our findings suggest that adaptation of the EPDS for use in the United States with a focus on contextual equivalence and validity could improve the performance of the tool and patients' experiences with completing the tool. Future research is warranted on optimal methods to adapt the EPDS for mental health screening in the perinatal period in the United States.

Perinatal mood and anxiety disorders (PMADs) affect up to 20% of pregnant and postpartum women and can have negative sequelae for maternal-child health. Nurses with clinical and research roles are on the front line of efforts to assess for and assist with prevention and intervention with PMAD symptoms. Thus, they can play an essential role in enhancing the mental well-being of women in the perinatal period and maternal-child health outcomes. The aim of this article is to assist nurses in this work by outlining the Comprehensive Model of Mental Health during the Perinatal Period, a conceptual framework for considering clinical and research opportunities to enhance perinatal mental health. The framework uses key principles that recognize biopsychoneuroimmunologic mechanisms involved in mental health; the key role that the experience of matrescence ("becoming a mother") plays in mental health and maternal-child health; and the mother-infant dyad as the functional unit during the perinatal period. Examples are provided of how the key principles of this framework might be used to enhance research and clinical practice about PMADs and, ultimately, enhance maternal-child health outcomes.
