^*Vasculitis types include Behçet’s disease (n=48), central nervous system vasculitis (n=12), eosinophilic granulomatosis with polyangiitis (Churg-Strauss) (n=121), giant cell arteritis (n=32), granulomatosis with polyangiitis (Wegener’s) (n=332), IgA vasculitis (Henoch-Schönlein) (n=12), microscopic polyangiitis (n=42), polyarteritis nodosa (n=36), and Takayasu’s arteritis (n=57).

^**Identity was scored on scale from 0–22. All other dimensions were scored on a scale from 1–5. NC = not comparable across diseases due to disease-specific modifications to IPQ-R. NR = not reported.
