Childhood executive functioning inventory: Adaptação e propriedades psicométricas da versão Brasileira

Abstract

The aim of the study was to translate, adapt and investigate psychometric properties of Childhood Executive Functioning Inventory (CHEXI) for a sample of Brazilian children. After translation, cultural adaptation, back-translation and semantic equivalence performed by area judges, the Brazilian version of CHEXI was answered by parents and teachers of 408 children aged between 4 and 7 years, also evaluated with the Columbia Mental Maturity Scale and SNAP-IV. High internal consistency indices were found. Exploratory factor analysis yielded two factors for the Brazilian version: a more general factor of executive functions and one specific factor of inhibition. The scores on the subscales of planning, regulation and marginally working memory in CHEXI explained significantly the inattention indicator of SNAP-IV, while the score on the inhibition subscale explained the indicator of hyperactivity/impulsivity. The results provide good psychometric parameters for CHEXI, besides contributing to the studies with Executive functions and ADHD signs in Brazil.
