Psychometric properties of self-reported measures of active ageing: A systematic review protocol using COSMIN methodology

Abstract

Introduction Evaluation of active ageing is helpful in making public health policies, improving older adults' quality of life and confronting global ageing challenges. However, there remains no systematic review to summarise all active ageing assessment tools and report their psychometric properties. This study aims to apply the COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) methodology to review the psychometric properties of active ageing assessment tools obtained by multiple validation studies. Methods and analysis Studies that aim to validate patient-reported outcome measures (PROMs) of active ageing in older adults aged 60 and over and report one or more psychometric properties are eligible for this systematic review. We will consider studies conducted in any country or setting published either in English or Chinese. The following databases will be searched: PubMed, EMBASE, CINAHL, Web of Science, Cochrane Library, ProQuest Dissertations and Theses, CNKI, and Wanfang. Data extraction, assessment of methodological quality, summary of the quality of PROMs and grading of quality of evidence will be conducted according to the COSMIN methodology. Ethics and dissemination This study will not collect individual data. Therefore, obtaining ethical approval is not applicable. The results will be disseminated through peer-reviewed journals and conferences and will help researchers choose active ageing assessment tools. PROSPERO registration number CRD42021287395.
