Abstract
Objective
The authors aimed to develop and validate the Computerized Adaptive Testing System
for Assessing 5 Functions in Patients with Stroke (CAT-5F) based on the Barthel Index
(BI), Postural Assessment Scale for Stroke patients (PASS), and Stroke Rehabilitation
Assessment of Movement (STREAM) to improve the efficiency of assessment. The purposes
of the CAT-5F assessment are to describe patients’ levels of impairments or disabilities
in the 5 functions and to serve as an outcome measure in patients with stroke.
Design
This is a data-mining study based on data from a previous study using simulation analysis
to develop and validate the CAT-5F.
Setting
One rehabilitation unit in a medical center in Taiwan served as the setting for this
study.
Participants
Data were retrieved from totals of 540 (initial assessment) and 309 (discharge assessment)
participants with stroke assessed in a previous study. The assessment data (N=540)
were from the BI, PASS, and STREAM.
Interventions
Not applicable.
Main Outcome Measures
The outcome measures for this study were from BI, PASS, and STREAM.
Results
The CAT-5F using the optimal stopping rule (limited reliability increased <0.010)
had good Rasch reliability across the 5 functions (0.86-0.96) and needed 12.7 items,
on average, for the whole administration. The concurrent validity (Pearson product-moment
correlation coefficient, r=0.91-0.96) and responsiveness (standardized response mean=0.33-0.91) of the CAT-5F
were sufficient in the patients.
Conclusion
The CAT-5F has sufficient administrative efficiency, reliability, concurrent validity,
and responsiveness to simultaneously assess basic activities of daily living, postural
control, upper extremity/lower extremity motor functions, and mobility in patients
with stroke.
