Cross-cultural adaptation of the SCATBI instrument for cognitive-linguistic abilities after traumatic brain injury.

Abstract

To perform the cross-cultural adaptation of the "Scales of Cognitive Ability for Traumatic Brain Injury" (SCATBI). After the translation and back-translation phases, a multidisciplinary committee judged and elaborated versions in order to maintain its conceptual equivalence, content, comprehensibility and contextual adjustment for Brazilian population. The final version was tested on 55 healthy subjects. The individuals' mean age was 41.75 ± 17.40 years (range = 18-81), 69% were women and they had a mean schooling of 12.96 ± 4.55 years. Higher total scores were positively correlated with years of schooling (p < 0.001) and social-economic status (p = 0.001), while older aged individuals performed worse than younger ones (p = 0.001). Both genders performed similarly on all domains of the instrument, except for "organization" ability, where women performed significantly better than men (p = 0.02). The Brazilian version of SCATBI is a useful tool for the diagnosis and monitoring of cognitive impairments after a traumatic brain injury.
