Test-Retest Reliability of Postpartum Depression Risk Factors Questionnaire (PDRFQ) and Edinburgh Postnatal Depression Scale (EPDS)

Studies have suggested that postpartum depression can lead to adverse outcomes. Having a reliable tool to assess for postpartum depression would assist in evidenced-based screening for risk factors and associated symptoms to facilitate timely interventions. Previously, validation of the PDRFQ and EPDS was performed and allowed for the evidence-based use of both tools together in nursing practice. The purpose of this study is to examine test-retest reliability of the PDRFQ+EPDS, a 19-item questionnaire, in order to implement the revised version into routine postpartum nursing care. The nursing theory used to shape this study is Betty Neuman’s Systems Model, focusing on stressors and reactions that weaken the lines of defense and resistance, ultimately affecting basic structure. This is a prospective, cross-sectional, descriptive study which is part of a larger longitudinal validation study. Mothers will be enrolled during their postpartum hospital stay and asked to complete a second copy of the PDRFQ+EPDS while inpatient to provide test-retest reliability when compared to the previously completed PDRFQ+EPDS, given as part of routine care. A convenience sample of n=x postpartum mothers will be recruited from a Midwest hospital. SPSS 21 software will be used to analyze data to determine test-retest reliability. Results are pending. Conclusions are pending. Limitations include convenience sampling, limited generalizability, and self-reporting. The primary implication is confirming reliability of the revised PDRFQ+EPDS for implementation into nursing practice.
