JOLY, Maria Cristina Rodrigues Azevedo  and  MARTINS, Ronei Ximenes. Validity study of technology performance scale for students. Psicol. esc. educ. [online]. 2006, vol.10, n.1, pp. 41-52. ISSN 1413-8557.

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.
