Objectives: To estimate the test-retest reliability and validity of the Chedoke Arm and Hand Activity Inventory (CAHAI) and to test whether the CAHAI was more sensitive to change in upper-limb function than the Impairment Inventory of the Chedoke-McMaster Stroke Assessment (CMSA) and the Action Research Arm Test (ARAT). Design: Construct validation process. Setting: Inpatient/outpatient rehabilitation facilities. Participants: Stratified sample of 39 survivors of stroke: 24 early (mean age, 71.4y; mean days poststroke, 27.3) and 15 chronic (mean age, 64.0y; mean days poststroke, 101.7). Intervention: Regular therapy. Main Outcome Measures: Intraclass correlation coefficients (ICCs), receiver operating characteristic (ROC), standard error of measurement, and correlation coefficients. Results: High interrater reliability was established with an ICC of .98 (95% confidence interval [CI],.96-.99). The minimal detectable change score was 6.3 CAHAI points. Higher correlations were obtained between the CAHAI and the ARAT and CMSA scores compared with the CMSA shoulder pain scores (1-sided, P=.001). Areas under the ROC curves were as follows: CAHAI,.95 (95% Cl, 0.87-1.00); CMSA,.76 (95% Cl,.61-.92); and ARAT,.88 (95% Cl, 0.76-1.00). Conclusions: High interrater reliability and convergent and discriminant cross-sectional validity were established for the CAHAI. The CAHAI is more sensitive to clinically important change than the ARAT.
