Whānau Āwhina Plunket nurses’ views on the use of the PHQ-3 postnatal depression screening tool: a survey

Abstract

Introduction In New Zealand, nurses visiting families postnatally use the Patient Health Questionnaire-3 (PHQ-3) to screen and detect postnatal depression. Exploring nurses’ perception of the tool when using it with women across cultures is central to ensuring the PHQ-3 tool supports equitable screening and detection of postnatal depression, yet little is known about nurses’ confidence with, and use of, the tool with people of differing cultures. Aim The aim of this study was to understand nurses’ confidence in using the PHQ-3 to screen for postnatal depression, particularly its use cross-culturally. Methods Quantitative online survey research was carried out in 2019. Fifty-two percent of eligible registered nurses participated (n = 187), completing Likert scale responses and open questions about the use of the screening tool with specific groups, and barriers and facilitators to screening. Results Ninety-five percent of participants were confident in their use of the PQH-3, 70% of nurses agreed the PHQ-3 supports the identification of postnatal depression, and most respondents (54.5%) disagreed that the PHQ-3 was a good screening tool cross-culturally. Discussion Nurses were confident in their use of the PHQ-3, and it was relatively highly regarded in its ability to detect postnatal depression. However, less confidence in its use across cultures implies the PHQ-3 does not translate to evidence-based, cross-cultural care. To serve culturally diverse populations, consultation is needed on both languages used and cultural practices so that tools are appropriate, otherwise they cannot be validated for use cross-culturally.
