Objective: To examine the test-retest reliability, convergent validity, and
predictive validity of the comprehensive activities of daily living (CADL)
measure in patients with stroke. Design: A repeated-assessments design, 10-14
days apart, was used to examine test-retest reliability in 70 patients. In the
validity study, a further 168 patients were assessed at 6 months and 1 year after
stroke. Setting: Three rehabilitation units. Main outcome measures: The CADL
measure, providing Rasch-calibrated scores, assesses the entire continuum of
basic and instrumental activities of daily living. Both domains (self-care and
mobility) of the stroke-specific quality of life questionnaire (SS-QOL) were used
to examine the convergent validity. The summary score of the SS-QOL was used as
the criterion for examining the predictive validity of the CADL measure. Results:
The test-retest reliability was excellent (intraclass correlation coefficient =
0.96). The CADL measure and both domains of the SS-QOL exhibited strong
associations at 6 months and 1 year post-stroke (Pearson's r >/= 0.77). The score
of the CADL at 6 months post-stroke was highly correlated with that of the SS-QOL
at 1 year post-stroke (r = 0.75). Conclusion: The CADL measure showed
satisfactory test-retest reliability, convergent validity, and predictive
validity in patients with stroke.
