Validating remote cognitive tests in the Wisconsin Registry for Alzheimer's Prevention.

ABSTRACT:

Introduction

Remote cognitive assessment addresses barriers to research participation for older participants, but continuity in longitudinal studies is a challenge. We examined whether scores from telephone-based assessments (T-COG) were valid and reliable estimates of in-person traditional neuropsychological findings.

Methods

Participants in the Wisconsin Registry for Alzheimer's Prevention (WRAP) who had completed in-person testing within the prior 12 months were invited to complete a follow-up T-COG visit. Bland-Altman plots and intraclass correlations were used to assess repeatability and bias.

Results

Correlations between in-person and T-COG scores were of moderate to large magnitude (Pearson r: 0.57 to 0.80, intraclass correlation coefficients: 0.52 to 0.
