The study found that remote, technician-guided cognitive assessments can provide valid and reliable measurements in multiple sclerosis. By comparing conventional in-person testing and assessing test-retest reliability, the results showed that remote-administered SDMT and CVLT-II were very similar to in-person results. The findings suggest that remote assessment is a viable option for assessing cognitive function in MS.
Objectives: Determine the validity and reliability of a remote, technician-guided cognitive assessment for multiple sclerosis (MS), incorporating the Symbol Digit Modalities Test (SDMT) and the California Verbal Learning Test, Second Edition (CVLT-II). Methods: In 100 patients, we compared conventional in-person testing to remote, web-assisted assessments, and in 36 patients, we assessed test-retest reliability using two equivalent, alternative forms. Results: In-person and remote-administered SDMT (r = 0.85) and CVLT-II (r = 0.71) results were very similar. Reliability was adequate and alternative forms of SDMT (r = 0.92) and CVLT-II (r = 0.81) produced similar results. Conclusions: Findings indicate remote assessment can provide valid, reliable measures of cognitive function in MS.
