Construção e Estrutura Fatorial de uma Escala de Polidez Infantil

– Construction and Factorial Structure of an Infant Politeness Scale The aim of this study was to develop and evaluate psychometric parameters of the child, parent and teacher versions of the Escala de Polidez Infantil (EPI – Infant Politeness Scale). Initially, the development and evaluation of the understanding of the EPI items was presented. Next, the validity of these versions was investigated through their factorial structures. In this stage, 146 children (74 boys) with a mean of 8.99 years of age ( SD =1.46) and 4.10 years of study ( SD =1.36) participated. The parents (136 mothers and 88 fathers) and the teachers ( n =22) of these children also responded. In the exploratory factor analysis the most adequate solution for the three versions contained two factors (moral politeness and conventional politeness). The parent and teacher versions presented more adequate fit and omega reliability indices, while the child version will need adjustments. The scale presents a viable alternative for measuring the politeness precursor of moral behavior.
