Remote administration of the symbol digit modalities test to individuals with multiple sclerosis is reliable: A short report

BACKGROUND: The Symbol Digit Modalities Test (SDMT) is the gold standard for cognitive screening in multiple sclerosis (MS). OBJECTIVE: Due to the recent COVID-19 pandemic and the increased need for virtual clinical visits, we examined the reliability of remote administration of the SDMT vs. standard in-person administration to individuals with MS. METHODS: Pearson’s correlation analysis was performed between SDMT scores on the in-person and remote administrations. RESULTS: For n = 132 participants, remote and in-person SDMT scores were strongly correlated (r = .80, p = .000). CONCLUSION: Remote administration of the SDMT is a reliable cognitive screening approach in MS.
