Questionnaires assessing knowledge and beliefs about musculoskeletal conditions are potentially suitable for use, but further research is needed: a systematic review

Objectives: To evaluate the measurement properties of Patient -reported outcome measures (PROMs) for knowledge and/or beliefs about musculoskeletal conditions. Study Design and Setting: A systematic review was performed according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines. This review was prospectively registered on PROSPERO e ID: CRD42022303111. Electronic databases, reference lists, forward citation tracking, and contact with experts were used to identify studies. Eligible studies were reports developing or assessing a measurement property of a PROM measuring musculoskeletal condition specific -knowledge and/or beliefs. We assessed the methodological quality and measurement properties of included studies. A modified Grading of Recommendations Assessment Development and Evaluation approach was used to rate the quality of evidence for each PROM. Results: The literature search was performed from inception to 11th September 2023. Sixty records were included, reporting 290 individual studies, and provided information on 25 PROMs. Five PROMs presented sufficient structural validity, three presented sufficient cross-cultural validity, ten presented sufficient reliability, three presented sufficient criterion validity, six presented sufficient hypothesistesting, and four presented sufficient responsiveness. No PROM presented sufficient evidence for content validity, internal consistency, and measurement error. Based on the available evidence, no PROM was classified as suitable for use according to the COSMIN recommendations. Twenty-four PROMs are potentially suitable for use , and one PROM is not recommended for use . Conclusion: No PROM designed to assess knowledge and/or beliefs about musculoskeletal conditions meets the COSMIN criteria of suitable for use . Most PROMs identified in this systematic review were considered as potentially suitable for use and need further highquality research to assess their measurement properties. (c) 2024 The Author(s).
