Validity of performance scales for disability assessment in multiple sclerosis
Abstract
Researchers increasingly use self-reported health status assessments, but these require validation. Performance Scales (PS) is a self-report measure for multiple sclerosis (MS)-associated disability, assessing mobility, bowel/bladder, fatigue, sensory, vision, cognition, spasticity and hand function. The criterion validity of the total PS score was established using the Expanded Disability Status Scale (EDSS), but the construct and criterion validity of the individual subscales have not been established. We assessed the criterion and construct validity of the PS subscales. Forty-four patients with MS completed PS, and these criterion measurements: neurological examination (EDSS), the Multiple Sclerosis Functional Composite (MSFC), contrast acuity testing, and the Multiple Sclerosis Quality of Life Inventory. We assessed criterion and construct validity with Spearman rank correlations between PS subscales and the other measurements. PS correlated with the MSFC ( r = -0.58, P < 0.0001). The mobility, hand, vision, fatigue and bladder subscales correlated with their criterion measures ( r = 0.59—0.77, P < 0.0001). The sensory subscale correlated weakly with the sensory functional system score ( r = 0.39, P = 0.01 ), and the cognitive subscale did not correlate with the PASAT ( r = -0.17, P = 0.26). This study supports the criterion and construct validity of PS overall, and its mobility, hand, vision, fatigue, and bladder subscales. Further assessment of the cognitive, sensory and spasticity subscales is needed. Multiple Sclerosis 2007; 13: 1176—1182. http://msj.sagepub.com

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
