OBJECTIVE: To examine the intrarater reliability, interrater reliability, and
responsiveness of the Activities of Daily Living Computerized Adaptive Testing
system (ADL CAT) in patients with stroke. DESIGN: One repeated-measures design
(at an interval of 7d) was used to examine the intrarater reliability and
interrater reliability of the ADL CAT. For the responsiveness study, participants
were assessed with the ADL CAT at admission to the rehabilitation ward and at
discharge from the hospital. SETTING: Eight rehabilitation units. PARTICIPANTS:
Three different (nonoverlapping) groups of patients (N=157) were recruited.
Fifty-five and 42 outpatients with chronic stroke participated in the intrarater
and interrater reliability studies, respectively; 60 inpatients who had recently
had a stroke participated in the responsiveness study. INTERVENTIONS: Not
applicable. MAIN OUTCOME MEASURE ADL CAT RESULTS: The intraclass correlation
coefficient values were .94 and .80 for the ADL CAT in the intrarater reliability
and interrater reliability studies, respectively. The classical test theory-based
minimal detectable change values were 6.5 and 9.5 for the ADL CAT in the
intrarater reliability and interrater reliability studies, respectively. The
Kazis' effect size and standardized response mean of the ADL CAT were moderate
(.62-.73). CONCLUSIONS: The ADL CAT has good intrarater reliability and
interrater reliability in outpatients with chronic stroke, and sufficient
responsiveness in inpatients with stroke undergoing inpatient rehabilitation.
Further investigations on the responsiveness of the ADL CAT in outpatients are
needed to obtain more evidence on the utility of the ADL CAT.
