TLDR
Remote and in-person SDMT administrations appear interchangeable, and correlations between baseline and follow-up were comparable across modalities.
Abstract
BACKGROUND
Remote administration of the Symbol Digit Modalities Test (SDMT) requires validation.OBJECTIVES
Examine interchangeability of remote and in-person SDMT administrations in persons with MS.METHODS
After in-person baseline administration, follow-up administration was either performed in-person (n = 72) or remotely via videoconferencing (n = 143). We examined whether raw score change from baseline to follow-up differed between in-person and remote follow-up modalities.RESULTS
SDMT raw score change did not differ between in-person and remote follow-up modalities (-0.1 ± 5.9 vs -0.2 ± 6.2, p = 0.995, d = 0.008), and correlations between baseline and follow-up were comparable across modalities (0.86 vs 0.88).CONCLUSIONS
Remote and in-person SDMT administrations appear interchangeable.
