There is a benefit to developing computerized test batteries that can be used across large, longitudinal epidemiologic studies and prevention/intervention trials to facilitate comparison and harmonization across studies. The National Institute of Health (NIH) Toolbox is a royalty-free battery of tests designed to measure cognitive, sensory, motor, and emotional functioning that can be used across the lifespan and leverages Item Response Theory (IRT). Over 250 researchers from 80 institutions contributed to the scientific and psychometric development of the NIH toolbox. Today we bring you our discussion with Julie N. Hook, PhD, MBA, ABPP-CN, about the NIH Toolbox and its current and future use to improve collaboration across multisite, international neuropsychological studies, in addition to potential clinical applications.
