Methodology for the development of normative data for ten Spanish-language neuropsychological tests in eleven Latin American countries

Abstract

BACKGROUND: Within the field of neuropsychology, there is a significant lack of normative data for individuals in Latin America. OBJECTIVE: To describe the methodology utilized to obtain the data and create norms for 10 Spanish-language neuropsychological tests administered in 11 Latin-American countries in a sample of 3,977 healthy individuals between the ages 18 and 90. METHOD: The same data manipulation process was applied to the data collected (regardless of the scale or country) using a regression-based procedure that takes into account sex, age, and educational influences on neuropsychological test scores. CONCLUSIONS: Following this procedure, we were able to generate age, education, and sex (if relevant) based norms for each test in each of the 11 countries studied. These norms are presented in the 10 articles that comprise this special issue.
