Development, woman-centricity and psychometric properties of maternity patient-reported experience measures: a systematic review

OBJECTIVE: Valid and reliable maternity patient-reported experience measures are critical to understanding women's experiences of care. They can support clinical practice, health service and system performance measurement, and research. The aim of this review is to identify and critically appraise the risk of bias, woman-centricity (content validity), and psychometric properties of maternity patient-reported experience measures published in the scientific literature. DATA SOURCES: MEDLINE, CINAHL Plus, PsycINFO, and Embase were systematically searched for relevant records between January 1, 2010 and July 10, 2021. STUDY ELIGIBILITY CRITERIA: We searched for articles describing the instrument development of maternity patient-reported experience measures and measurement properties associated with instrument validity and reliability testing. Articles that described patient-reported experience measures developed outside of the maternity context and articles that did not contribute to the instruments' development, content validation, and/or psychometric evaluation were excluded. METHODS: Included articles underwent risk of bias, content validity, and psychometric properties assessments in line with the COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) guidance. Patient-reported experience measure results were summarized according to language subgroups. An overall recommendation for use was determined for each patient-reported experience measure language subgroup. RESULTS: A total of 54 studies reported on the development and psychometric evaluation of 25 maternity patient-reported experience measures, grouped into 45 language subgroups. The quality of evidence underpinning the instruments' development was generally poor. Only 2 (4.4%) patient-reported experience measures reported sufficient content validity, and only 1 (2.2%) received a level "A" recommendation, required for real-world use. CONCLUSION: Maternity patient-reported experience measures demonstrated poor-quality evidence for their measurement properties and insufficient detail about content validity. Future maternity patient-reported experience measure development needs to prioritize women's involvement in deciding what is relevant, comprehensive, and comprehensible to measure. Improving the content validity of maternity patient-reported experience measures will improve overall validity and reliability and facilitate real-world practice improvements. Standardized patient-reported experience measure implementation also needs to be prioritized to support advancements in clinical practice for women.
