Abstract
Objective: The purpose of this exploratory study was to describe associations between NIH Toolbox-Cognition Battery subtests and legacy measures of neurocognitive function in two samples with neurological conditions (stroke and sickle cell disease (SCD)). Method: This exploratory secondary analysis uses data from two studies that assessed cognition at one time point using the NIH Toolbox-Cognition Battery, the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), and subtests from the Delis-Kaplan Executive Functions System (DKEFS). People with stroke (n = 26) and SCD (n = 64) were included. Associations between the NIH Toolbox-Cognition Battery subtests and corresponding legacy measures were examined using linear correlations, Bland-Altman analysis, and Lin's Concordance Correlation Coefficient. Results: Linear correlations and Lin's Concordance Correlation Coefficient were poor to strong in both samples on NIH Toolbox-CB subtests: Flanker Inhibitory Control and Attention (r =.35 to.48, Lin CCC =.27 to.37), Pattern Comparison Processing Speed (r =.40 to.65, Lin CCC =.37 to.62), Picture Sequence Memory (r =.19 to.55, Lin CCC =.18 to.48), Dimensional Change Card Sort (r =.39 to.77, Lin CCC =.38 to.63), Fluid Cognition Composite (r =.88 to.90, Lin CCC =.60 to.79), and Total Cognition Composite (r =.64 to.83, Lin CCC =.60 to.78). Bland-Altman analyses demonstrated wide limits of agreement across all subtests (-3.17 to 3.78). Conclusions: The NIH Toolbox-Cognition Battery subtests may behave similarly to legacy measures as an overall assessment of cognition across samples at risk for neurological impairment. Findings should be replicated across additional clinical samples.
