Standard form of the Boston Naming Test: Normative data for the Latin American Spanish speaking adult population.

OBJECTIVE To generate normative data on the Boston Naming Test (BNT) across 10 countries in Latin America, with country-specific adjustments for gender, age, and education, where appropriate. METHOD The sample consisted of 3,779 healthy adults who were recruited from Argentina, Bolivia, Chile, Cuba, El Salvador, Guatemala, Mexico, Paraguay, Peru, and, Puerto Rico. Each subject was administered the BNT as part of a larger neuropsychological battery. A standardized five-step statistical procedure was used to generate the norms. RESULTS The final multiple linear regression models explained between 3-32% of the variance in BNT scores. Although t-tests showed significant differences between men and women for Mexico, Argentina, Chile, Cuba, Guatemala, and Bolivia on the BNT, none of the six countries had an effect size larger than 0.3. As a result, gender-adjusted norms were not generated. CONCLUSIONS This is the first normative multicenter study conducted in Latin America to generate norms for the BNT; this study will have substantial repercussions for the practice of neuropsychology throughout the global region.
