This study introduces a special series on validity studies of the Cognition Battery (CB) from the United States National Institutes of Health (National Institutes of Health (NIH) Toolbox for the Assessment of Neurological and Behavioral Function (NIHTB) in an adult sample. The NIHTB-CB is designed to provide a brief, comprehensive, common set of measures to allow comparisons among disparate studies and to improve scientific communication. It contains four modules, each addressing a different domain of neurologic/behavioral function: Cognition, Emotion, and Motor, and Sensory Function. This first study in the series describes the sample, each of the seven instruments in the NIHTB-CB briefly, and the general approach to data analysis. Data are provided on test-retest reliability and practice effects, and raw scores (mean, standard deviation, range) are presented for each instrument and the gold standard instruments used to measure construct validity. Accompanying papers provide details on each instrument, including information about instrument development, psychometric properties, age and education effects on performance, and convergent and discriminant construct validity. One study in the series is devoted to a factor analysis of the NIHTB-CB in adults and another describes the psychometric properties of three composite scores derived from the individual measures representing fluid and crystallized abilities and their combination.
