Abstract

© 2017 Revista de Neurología. Introduction. Neuropsychological assessment in individuals with intellectual disability is of utmost importance in order to determine the cognitive deficits underlying brain dysfunction and limiting intellectual functioning and adaptive behavior. However, no neuropsychological batteries in Spanish language have been created and validated for this population. Aim. To adapt the ‘programa integrado de exploración neuropsicológica-test Barcelona’ and to validate the new version, the Barcelona Test for Intellectual Disability (TB-DI). To create normative data for its clinical use. Subjects and methods. The original test was modified based on data from a pilot sample of 65 individuals with intellectual disability. In order to study the psychometric properties of the TB-DI, it was administered to a sample of 170 individuals with intellectual disability and to a group of 60 individuals without it. The relevant variables for stratification of normative data were determined by means of regression models. Results. The TB-DI was finally composed by 67 subtests grouped in eight cognitive domains and it showed good psychometric properties. Normative data were created for five groups taking into account intellectual disability level, age and acquired curricular competence. These data were organized in percentiles in a way that allows the creation of cognitive profiles in the clinical and experimental fields. Conclusion. The TB-DI constitutes a tool of high applicability in the population with intellectual disability. It shows adequate validity and reliability, and it has good psychometric properties. The cognitive profiles obtained by the TB-DI will provide valuable information for the treatment of adult adults with mild and moderate intellectual disability.
