Objectives: To systematically review the psychometric properties of outcome measurement instruments used in ANCA-associated vasculitis (AAV). Methods: Medline, EMBASE, Cochrane, Scopus and Web of Science were searched from inception to 14 July 2020 for validation studies of instruments used in AAV. Following the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) and OMERACT frameworks, different psychometric properties (validity, reliability, responsiveness and feasibility) were summarized. Risk of bias was assessed according to the COSMIN checklist. Results: From 2505 articles identified, 32 met the predefined selection criteria, providing information on 22 instruments assessing disease activity (n = 7), damage (n = 2), activity and damage (n = 1), health-related quality of life (HRQoL; n = 9) and function (n = 3). Most of the instruments were tested in AAV as a group or in granulomatosis with polyangiitis only. The BVAS, any version, the Vasculitis Damage Index (VDI) and the AAV-Patient-Reported Outcome (AAV-PRO) have been more extensively validated than the other instruments. BVAS for Wegener Granulomatosis (BVAS/WG) has been shown to be valid for measuring disease activity [correlation with Physician global assessment (r = 0.90)], reliability (inter-observer intraclass correlation coefficient = 0.97), responsiveness and feasibility. For damage, VDI was shown to be moderately valid (correlations with BVAS version 3 at 6 months r = 0.14, BVAS/WG at 1 year r = 0.40 and 5 years r = 0.20), and feasible. For HRQoL, AAV-PRO demonstrated validity (correlations of the six AAV-PRO domains with EQ-5D-5L: -0.78 to -0.55; discrimination between active disease and remission, P < 0.0001 for all comparisons). The overall performance of instruments assessing function was low-to-moderate. Conclusion: Among the 22 outcome measurement instruments used for AAV, BVAS (any version), VDI and AAV-PRO had the strongest psychometric properties.

Abstract
Objectives: To systematically review the psychometric properties of outcome measurement instruments used in ANCA-associated vasculitis (AAV). Methods: Medline, EMBASE, Cochrane, Scopus and Web of Science were searched from inception to 14 July 2020 for validation studies of instruments used in AAV. Following the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) and OMERACT frameworks, different psychometric properties (validity, reliability, responsiveness and feasibility) were summarized. Risk of bias was assessed according to the COSMIN checklist. Results: From 2505 articles identified, 32 met the predefined selection criteria, providing information on 22 instruments assessing disease activity (n = 7), damage (n = 2), activity and damage (n = 1), health-related quality of life (HRQoL; n = 9) and function (n = 3). Most of the instruments were tested in AAV as a group or in granulomatosis with polyangiitis only. The BVAS, any version, the Vasculitis Damage Index (VDI) and the AAV-Patient-Reported Outcome (AAV-PRO) have been more extensively validated than the other instruments.
