We assessed the validity and reliability of a virtual environment
technology (VET)-based cognitive assessment program that was developed as a
measurement tool of cognitive abilities in patients after a stroke. DESIGN:
Twenty participants diagnosed with stroke caused by unilateral brain lesions were
enrolled to assess the VET program's validity and test-retest reliability.
Participants underwent evaluation by paper-based neuropsychological tests
including the Korean Mini-Mental Status Examination, the Korean-Wechsler Adult
Intelligence Scale, the Motor Free Visual Perception Test, Rey-Kim Memory Test,
and Kim's Frontal-Executive Neuropsychologic Test as well as the VET-based
cognitive assessment. Major variables and indices of the VET program were
calculated. The VET program validity was evaluated using a simple correlation
analysis between variables from the VET program and conventional paper-based
neuropsychological measurements, and the reliability was evaluated by
investigating the test-retest correlation coefficients. RESULTS: Major variables
and indices of the VET program in patients with stroke correlated significantly
with the related scores of paper-based neuropsychological tests. In addition, the
test-retest reliability analysis revealed that the correlation coefficients
ranged from 0.528 to 0.926. CONCLUSION: The VET-based cognitive assessment
program showed adequate reliability and validity as a method of cognitive
assessment in patients after stroke.
