Abstract
Purpose
To analyze WHODAS 2.0’s diagnostic capacity and accuracy in stroke survivors.
Methods
Cross-sectional methodological study, in which individuals with chronic stroke were evaluated. Disability was considered the outcome variable, being evaluated by WHODAS 2.0; the modified Rankin scale (mRS) was used as the parameter variable. Disability was categorized in two levels being: “No or mild disability” (mRS 0–2) and “Moderate to severe disability” (mRS 3–5). To identify the cutoff point, a Receiver-Operating Characteristic (ROC) curve was constructed with a confidence interval (CI) of 95% and considering sensitivity and specificity.
Results
The cutoff point >39.62 proved acceptable for distinguishing individuals with moderate/severe disability from individuals with no or mild disability (≤39.62 points), with 66.22% sensitivity, 72.41% specificity, positive predictive value (PPV) of 45.45%, and negative predictive value (NPV) of 84.74%. The area under the curve (AUC) was 0.747 (CI 95%: 0.65–0.83; p < 0.001).
Conclusion
WHODAS 2.0 demonstrated acceptable diagnostic capacity and the cutoff point of 39.62 proved suitable for distinguishing individuals with moderate/severe disability from those with no or mild disability after stroke.
WHODAS 2.0 demonstrated acceptable diagnostic capacity.
The WHODAS 2.0 cut-off point of >39.62 allows stratification of post-stroke disability into two different levels (no/mild disability versus moderate/severe disability).
These results facilitate clinical decision-making by rehabilitation professionals.
