The specific computerized assessment battery (CAB) evaluated is valid for cognitive screening of people with multiple sclerosis (MS) and may be more likely to detect prolonged response times and impaired executive function, according to a recent study. 81 people with MS (PwMS) and 15 healthy controls (HC) completed the CAB and a set of traditional neuropsychological tests recommended for MS on the same day. Principal component factor analysis was used to assess construct validity. For criterion validity, the gold standard definition of cognitive impairment was a score of ≥1.5SD below average on at least 1 cognitive domain, based upon traditional test normative data. Researchers found:
- Traditional and computerized tests of memory, processing speed, visuospatial, and executive function converged by factor analysis.
- Computerized tests detected cognitive impairment with 85% sensitivity and 70% specificity.
- PwMS classified as impaired on only the computerized battery had significantly prolonged response times and a higher rate of unemployment compared with PwMS classified as unimpaired on both batteries.
- Poor executive function was more likely to be revealed by the CAB.
