Estudo de validade de uma escala de desempenho em tecnologias para estudantes

This study aims to evaluate the psychometric characteristics of the Escala de Desempenho em Tecnologias (EDETEC). 463 students with age between 15 and 60 years (M=22; DP=6,9) have participated, 53,1% female, 84.9% from public schools. EDETEC, which has 95 Likert items with a fouranswer choice each, was answered individually. The results showed a good internal consistency (±=0,97). The internal reliability, verified by the splithalf method, was 0,87 and it showed that the items were homogenous. The factor analysis found three factors that explained 47,25% of the variations. So 39 items (with communalities < 0,40) were eliminated to the first version.This study aims to evaluate the psychometric characteristics of the Escala de Desempenho em Tecnologias (EDETEC). 463 students with age between 15 and 60 years (M=22; DP=6,9) have participated, 53,1% female, 84.9% from public schools.
