The goal of this study was to adapt and validate this battery to the Portuguese population of MS patients. The Portuguese version of BRBN-T was applied to a stratified control national sample of 334 individuals (stratification criteria: age, sex, educational level and geographic location) and to a clinical sample of 127 MS patients from eight national hospitals. Gender, education and age effects were explored. Through the exploration of its psychometrics properties, we produced the Portuguese norms of BRBN-T. The normative data is presented as a regression-based formula to adjust test scores for gender, education and age. The correspondence between adjusted scores and percentile distribution was calculated for each test of the battery. The normative data produced in this study improves the applicability of BRBN-T for both clinical and research proposes in the Portuguese population.
