The mean scores on each IPQ\u2010R dimension were compared across different types of vasculitis. Cluster analysis and stepwise regression identified predictors of negative illness perception. Fatigue was measured using the general subscale of the Multidimensional Fatigue Inventory (MFI\u201020). Patient\u2010reported measures of disease activity and IPQ\u2010R dimensions were assessed in relation to MFI\u201020 scores using linear regression in sequential, additive models with model\u2010fit comparisons.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In total, 692 participants with 9 types of vasculitis completed the IPQ\u2010R. For 6 of the 8 IPQ\u2010R dimensions, there were no significant differences in mean scores between the different vasculitides. Scores in the identity and cyclical dimensions were significantly higher in Beh\u00e7et's disease compared with other types of vasculitis (13.5 versus 10.7 for identity and 4.0 versus 3.2 for cyclical [<jats:italic>P<\/jats:italic> &lt; 0.05]). Younger age (odds ratio [OR] 1.04, 95% confidence interval [95% CI] 1.02\u20131.06), depression (OR 4.94, 95% CI 2.90\u20138.41), active disease status (OR 2.05, 95% CI 1.27\u20133.29), and poor overall health (OR 3.92, 95% CI 0.88\u201317.56) were associated with negative illness perceptions. The sequential models demonstrated that the IPQ\u2010R dimensions explained an equivalent proportion of variability in fatigue scores compared with measures of disease activity.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Illness perceptions are similar across different types of vasculitis, and younger age is a risk factor for negative illness perceptions.
