VALE, Ana Paula; SUCENA, Ana  e  VIANA, Fernanda. Prevalence of dyslexia between Portuguese children from elementary school. Rev. Lusófona de Educação [online]. 2011, n.18, pp.45-56. ISSN 1645-7250.

The purpose of the present study was to determine the prevalence of dyslexia among Portuguese 2nd, 3rd and 4th graders. A sample of 1460 children underwent an assessment process including two screening tests of reading and, in accordance with the established criteria, 155 of those children were further tested on general cognitive ability and phonological awareness. Children were tested collectively on the screening tests and individually on the other. Since this was the first study of the kind carried out in Portugal, strict criteria were used to select a child as dyslexic. Results show that 5.4% of children met all the criteria to be classified as dyslexic, a percentage that falls within the prevalence range recently reported in other countries.

Palavras-chave : dyslexia; prevalence; Portuguese children.
