OBJECTIVE: To develop a computerized adaptive testing system of the Functional
Assessment of Stroke (CAT-FAS) to assess upper- and lower-extremity (UE/LE) motor
function, postural control, and basic activities of daily living with optimal
efficiency and without sacrificing psychometric properties in patients with
stroke. DESIGN: Simulation study. SETTING: One rehabilitation unit in a medical
center. PARTICIPANTS:
Patients with subacute stroke (N=301; mean age,
67.3+/-10.9; intracranial infarction, 74.5%). INTERVENTIONS: Not applicable. MAIN
OUTCOME MEASURES: The UE and LE subscales of the Fugl-Meyer Assessment, Postural
Assessment Scale for Stroke Patients, and Barthel Index. RESULTS: The CAT-FAS
adopting the optimal stopping rule (limited reliability increase of <.010) had
good Rasch reliability across the 4 domains (.88-.93) and needed few items for
the whole administration (8.5 items on average). The concurrent validity (CAT-FAS
vs original tests, Pearson r=.91-.95) and responsiveness (standardized response
mean, .65-.76) of the CAT-FAS were good in patients with stroke. CONCLUSIONS: We
developed the CAT-FAS, and our results support that the CAT-FAS has sufficient
efficiency, reliability, concurrent validity, and responsiveness in patients with
stroke. The CAT-FAS can be used to simultaneously assess patients' functions of
UE, LE, postural control, and basic activities of daily living using, on average,
no more than 10 items; this efficiency is useful in reducing the assessment
burdens for both clinicians and patients.
