T-MoCA: A valid phone screen for cognitive impairment in diverse community samples

Introduction There is an urgent need to validate telephone versions of widely used general cognitive measures, such as the Montreal Cognitive Assessment (T-MoCA), for remote assessments. Methods In the Einstein Aging Study, a diverse community cohort (n = 428; mean age = 78.1; 66% female; 54% non-White), equivalence testing was used to examine concordance between the T-MoCA and the corresponding in-person MoCA assessment. Receiver operating characteristic analyses examined the diagnostic ability to discriminate between mild cognitive impairment and normal cognition. Conversion methods from T-MoCA to the MoCA are presented. Results Education, race/ethnicity, gender, age, self-reported cognitive concerns, and telephone administration difficulties were associated with both modes of administration; however, when examining the difference between modalities, these factors were not significant. Sensitivity and specificity for the T-MoCA (using Youden's index optimal cut) were 72% and 59%, respectively. Discussion The T-MoCA demonstrated sufficient psychometric properties to be useful for screening of MCI, especially when clinic visits are not feasible.

Automated summary

The study validated the effectiveness of the telephone version of the Montreal Cognitive Assessment (T-MoCA) using equivalence testing and presented conversion methods from T-MoCA to MoCA. Results showed that T-MoCA has sufficient psychometric properties for screening of mild cognitive impairment, especially when clinic visits are not feasible.
