Telehealth Equivalence of the Montreal Cognitive Assessment (MoCA): Results from the Emory Healthy Brain Study (EHBS) (P6-6.001)
Bibliographic record
Abstract
Objective: To characterize potential differences in Montreal Cognitive Assessment (MoCA) performance between in-person cognitive testing and video telehealth administration. In addition to global MoCA scores, we examined potential telehealth effects on mood (PHQ-8, GAD-7), and explored whether the presence of an observer at the participant’s home during remote MoCA testing influenced task performance. Background: Telehealth cognitive testing has become a common assessment approach following the COVID-19 pandemic when in-person testing was restricted for safety considerations. Although the equivalence of telehealth results to the traditional face-to-face testing is often assumed, formal equivalence validation is limited. Design/Methods: Scores from participants in the Emory Health Brain Study (EHBS) were contrasted based upon whether they were tested in the standard face-to-face (F2F) assessment (n=1205) or using a video telehealth administration (n=491). All EHBS participants were cognitively normal via self-report. Results: Total MoCA scores did not differ across administration method (F2F MoCA=26.6, SD=2.4, telehealth MoCA=26.5, SD=2.4). The 95% confidence interval for difference in administration was small (CI = −0.16 – 0.34). When examining individual MoCA domain scores, administration differences were either associated with no statistically significant effect, or if present were due to large sample sizes, were associated with small effect sizes and differences < 0.5 point. Groups did not differ on GAD-7, although F2F patients reported slightly higher GAD-7 scores of 0.4 point but well within the normal range. The presence of an observer during telehealth testing did not influence MoCA scores. Conclusions: While no single study design provides complete evidence of task equivalence between in-person and video telehealth assessment, this report with its large sample size and between subject cohort provides reassurance that administration mode does not introduce systematic performance differences for MoCA test administration. Continuing studies in clinically impaired groups will be needed to demonstrate the robustness of our findings.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
