A novel computer adaptive word list memory test optimized for remote assessment: Psychometric properties and associations with neurodegenerative biomarkers in older women without dementia

INTRODUCTION: This study established the psychometric properties and preliminary validity of the Stricker Learning Span (SLS), a novel computer adaptive word list memory test designed for remote assessment and optimized for smartphone use. METHODS: Women enrolled in the Mayo Clinic Specialized Center of Research Excellence (SCORE) were recruited via e‐mail or phone to complete two remote cognitive testing sessions. Convergent validity was assessed through correlation with previously administered in‐person neuropsychological tests (n = 96, ages 55–79) and criterion validity through associations with magnetic resonance imaging measures of neurodegeneration sensitive to Alzheimer's disease (n = 47). RESULTS: SLS performance significantly correlated with the Auditory Verbal Learning Test and measures of neurodegeneration (temporal meta‐regions of interest and entorhinal cortical thickness, adjusting for age and education). Test–retest reliabilities across two sessions were 0.71–0.76 (two‐way mixed intraclass correlation coefficients). DISCUSSION: The SLS is a valid and reliable self‐administered memory test that shows promise for remote assessment of aging and neurodegenerative disorders.
