Escala de Locus de controle ELCO/TELEBRÁS

open access: yesPsicologia: Reflexao E Critica, 1998
A scale with 28 items, the Organizational Locus of Control (ELCO), was built based on Rotter’s theory and Levenson’s scale. ELCO was validated on a sample of 350 employees of Telebras, a governmental firm in Brazil. As foreseen from the theory, a principal-axis factoring showed the presence of the expected two factors, namely internal and external ...
