The purpose of this study was to estimate the interrater reliability of
three shortened versions of the Chedoke Arm and Hand Activity Inventory (CAHAI-7,
CAHAI-8, CAHAI-9) when used with persons with acquired brain injury (ABI). The
CAHAI is an assessment of upper limb function with high reliability in the stroke
and ABI populations. In the stroke population, three shortened versions of the
measure have established reliability. Clinicians report time constraints as a
barrier to using standardized assessments; thus, establishing the reliability of
the shortened versions of the CAHAI in the ABI population may increase the use of
this measure. Method: This was an observational, parameter estimation study. The
participants were recruited from an in-patient ABI rehabilitation programme. The
administration of the CAHAI to six persons with ABI was video recorded, and the
video recordings were assessed by six clinicians to estimate interrater
reliability. A Latin square design was used to balance the order in which the
raters evaluated the videos. A repeated-measures analysis of variance was
performed, and the variance components were used to calculate an intra-class
correlation coefficient (ICC) and standard error of measurement (SEM) with 95%
confidence limits (CLs) for each of the shortened versions. Results: Interrater
reliability was high for all three versions: CAHAI-7, ICC=0.96 (95% CL: 0.89,
0.99; SEM 2.65); CAHAI-8, ICC=0.96 (95% CL: 0.90, 0.99; SEM 2.72); and CAHAI-9,
ICC=0.95 (95% CL: 0.85, 0.99; SEM 3.49). Conclusions: These results suggest that
the three shortened versions of the CAHAI demonstrate high reliability in the ABI
population. These versions may be particularly useful when time constraints or
patient tolerance are an issue.
