Web vs iPad: Validation
We recently completed an NIH-sponsored study evaluating potential mode effects associated with iPad versus web-based versions of the NIH Toolbox Cognition Battery. We found that adjustments were needed to scores on four of seven cognition measures in order to ensure consistency across web and iPad versions and accurate interpretation of normative scores. The NIH Toolbox app automatically applies these adjustments to cognition data on the iPad. These adjustments and the differences between iPad and web-based Cognition scores are described in the NIH Toolbox Cognition Battery Analysis Guide.
