Abstract
The NIH Toolbox is used extensively in various research settings, including clinical trials, observational studies, and longitudinal studies. Its validity and reliability have been systematically appraised only in adults. The current study systematically evaluated the validity and reliability of the NIH Toolbox for assessing neurocognitive, motor and emotional-behavioral functioning in children. Based on 22 studies including over 60,000 participants, sufficient evidence was found for the validity and reliability of most tests in the Cognition Battery and Motor Battery. However, there was insufficient evidence to assess the validity and reliability of the Emotion Battery. Thus, this review supports the use of the NIH Toolbox Cognition and Motor Batteries in assessing neurocognitive functioning in 3–17-year-olds.
