Abstract

Specific Language Impairment (SLI) is defined as an unexpected failure in linguistic abilities during a child’s early years of development. Children with SLI do not present significant impairment in nonverbal intellectual outcomes and do not lack normal environmental exposure to language. Brazilian and worldwide researchers have sought to understand the cultural implications of SLI in the Brazilian Portuguese language. Standardized and validated measures must be used in empirical studies. The present study systematically reviewed the instruments used to assess linguistic abilities in quantitative SLI research in Brazil. Three databases were chosen: Medline, SciELO, and Google Scholar. From a total of 828 articles retrieved, only 10 met the inclusion criteria. Seven standardized assessment measures were identified. However, only two of these reported psychometric properties using adequate normative data. No normalized instrument measured the entire spectrum of linguistic abilities. We discuss the results from the perspective of SLI theories and evidence in Brazil and worldwide.
