Bland‐Altman comparison of the 36‐ and the 12‐item versions for each domain of the WHODAS 2.0 (n=638). Domain 1: Limits of agreement (reference range for difference): −16.078 to 23.870; mean difference: 3.896 (CI, 3.119–4.672); range: 0.000–100.000; Pitman test of difference in variance: r=−0.161, P<0.001 (n=638). Domain 2: Limits of agreement (reference range for difference): −20.932 to 12.414; mean difference: −4.259 (CI, −4.907 to −3.611); range: 0.000–96.875; Pitman test of difference in variance: r=−0.547, P<0.001 (n=638). Domain 3: Limits of agreement (reference range for difference): −11.054 to 13.974; mean difference: 1.460 (CI, 0.973–1.947); range: 0.000–100.000; Pitman test of difference in variance: r=−0.168, P<0.001 (n=637). Domain 4: Limits of agreement (reference range for difference): −23.667 to 24.129; mean difference: 0.231 (CI −0.698 to 1.160); range: 0.000–100.000; Pitman test of difference in variance: r=−0.288, P<0.001 (n=638). Domain 5: Limits of agreement (reference range for difference): −28.995 to 26.392; mean difference: −1.302 (CI, −2.383 to −0.220); range: 0.000–100.000; Pitman test of difference in variance: r=−0.243, P<0.001 (n=632). Domain 6: Limits of agreement (reference range for difference): −32.166 to 25.527; mean difference: −3.320 (CI, −4.441 to −2.198); range: 0.000–89.583; Pitman test of difference in variance: r=−0.533, P<0.001 (n=638).
