Adaptação transcultural e validação do teste de inteligência fluída CFT20-R para população brasileira entre 8 1/2 e 17 anos

Abstract

The CFT 20-R is an instrument for the global assessment of intellectual capacity (intelligence), aimed at children and adolescents between 8 years and 6 months to 19 years old and for adults from 20 to 60 years old. In the present study, the CFT 20-R test was adapted and validated for children and adolescents aged 8 and a half to 17 years old. For this purpose, the semantic equivalence of the application instructions, measurement equivalence and operational equivalence were evaluated, having fluid intelligence as a construct and verifying the convergent validity of the results of fluid intelligence, of the non-verbal test CFT 20-R with the Raven’s Coloured Progressive Matrices. Semantic, operational and measurement equivalence steps were performed, according to current recommendations. Pre-test and subsequent data collection in municipal and state schools in Minas Gerais and in public and private schools in the state of Rio de Janeiro, totaling a sample of 511 exams. There was a good understanding of the instructions adapted from the stimulus notebook and the answer sheet header, moderate correlation (r = 0.4960) between the standard score of the Raven’s Coloured Progressive Matrices test and the total IQ of the CFT 20-R test and a correlation positive increase of 71% in the intercorrelation between subtests (serialization, classification, matrices and topology) with the main component which is fluid intelligence. The cross-cultural adaptation of the CFT20R test in the stimulus notebook and answer sheet proved to be effective and easy to understand for the Brazilian population aged 8 ½ years to 17 years. The Raven’s Coloured Progressive Matrices test and the CFT 20-R test measure moderately the same intelligence construct and the CFT 20-R test can be efficient for the assessment of fluid intelligence based on the theoretical model CHC.
