This study cross-validates the screening module of the Neuropsychological Assessment Battery (NAB-SM) with a battery of well validated neuropsychological tests (Convergent Validity Test Battery: CVTB) in a Traumatic Brain Injury (TBI) population. Forty-four participants with "mild-complicated" to "severe" TBI were recruited from a cohort of patients attending an outpatient clinic at a UK major trauma center. The NAB-SM Total Index score and an abbreviated short-form, from which a TBI Index was derived, both showed good classification accuracy in predicting impairment as measured by the CVTB mean score. These indices also accurately identified impairment as defined by the base rate of low scores across individual CVTB indices measuring mental processing speed, working memory, memory and executive functioning. The NAB-SM and its derived TBI index therefore have significant utility as a cognitive screening tool for use in either inpatient (acute) or outpatient TBI populations.
