Multicenter StudyNIH toolbox cognition tests following traumatic brain injury: Frequency of low scores.
To apply multivariate base rate analyses to the National Institutes of Health Toolbox Cognition Battery (NIHTB-CB) to facilitate the identification of cognitive impairment in individuals with traumatic brain injury (TBI). Research Method/Design: In a multisite cross-sectional design, 158 participants who sustained a complicated mild or moderate TBI (n = 74) or severe TBI (n = 84) at least 1 year earlier were administered the NIHTB-CB. The NIHTB-CB is comprised of 2 crystallized cognition tests (reflecting premorbid ability) and 5 fluid cognition tests, measuring processing speed, memory, and executive functioning. Base rates for obtaining 0 to 5 low fluid cognition scores were calculated across a range of cutoffs for defining a low test score (≤25th to 5th percentiles). Base rates of low scores in the TBI sample were compared to the NIHTB-CB normative sample using diagnostic accuracy statistics. ⋯ Premorbid ability stratified base rate tables provided in this article can guide researchers and clinicians in the interpretation of NIHTB-CB performance in adults with TBI.

Using the NIH Toolbox Cognition Battery (NIHTB-CB) in individuals with traumatic brain injury.
The NIH Toolbox for the Assessment of Neurological Behavior and Function Cognition Battery (NIHTB-CB) is a common data element for use in individuals with traumatic brain injury (TBI). This study evaluates its sensitivity and specificity in distinguishing individuals with complicated mild, moderate, or severe TBI, and provides support for the construct validity of the NIHTB-CB in individuals with TBI. ⋯ Findings provide evidence of construct validity and the clinical utility of the NIHTB-CB in individuals with TBI.
