The NIH Toolbox Cognitive Health Battery demonstrated convergent and discriminant validity against gold standard tests through a 5-factor structure that was invariant across adult age groups.

Does the NIH Neurobehavioral Toolbox Cognitive Health Battery (NIHTB-CHB) demonstrate convergent and discriminant validity compared to Gold Standard tests in adults?
The NIHTB-CHB demonstrates a valid 5-factor structure for assessing cognition across the adult lifespan.
The objective of this study is to evaluate the construct validity of the NIH Neurobehavioral Toolbox Cognitive Health Battery (NIHTB-CHB) in adults. Confirmatory factor analysis was used to evaluate the dimensional structure underlying the NIHTB-CHB and Gold Standard tests chosen to serve as concurrent validity criteria for the NIHTB-CHB. These results were used to evaluate the convergent and discriminant validity of the NIHTB-CHB in adults ranging from 20 to 85 years of age. Five dimensions were found to explain the correlations among NIHTB-CHB and Gold Standard tests: Vocabulary, Reading, Episodic Memory, Working Memory and Executive Function/Processing Speed. NIHTB-CHB measures and their Gold Standard analogues defined factors in a pattern that broadly supported the convergent and discriminant validity of the NIHTB-CHB tests. This 5-factor structure was found to be invariant across 20-60 year old (N=159) and 65-85 year old (N=109) age groups that were included in the current validity study. Second order Crystallized Abilities (Vocabulary and Reading) and Fluid Abilities (Episodic Memory, Working Memory, Executive/Speed) factors parsimoniously explained correlations among the five first order factors. These results suggest that the NIHTB-CHB will provide both fine-grained and broad characterization of cognition across the adult age span.
Mungas et al. (Tue,) conducted a cross-sectional in Cognitive assessment (n=268). NIH Toolbox Cognitive Health Battery (NIHTB-CHB) vs. Gold Standard tests was evaluated on Dimensional structure, convergent validity, and discriminant validity. The NIH Toolbox Cognitive Health Battery demonstrated convergent and discriminant validity against gold standard tests through a 5-factor structure that was invariant across adult age groups.
