Validação de uma medida de percepção de imagens organizacionais

The organizational images contruct has been considered useful for the understanding of human behavior at work. However, those images are almost always obtained from experts' or managers' opinions. A reliable measure of the perception of images, from the point of view of a broader set of organization members, is needed. The present work has tried to develop that measure, to test it within different organizational contexts in several parts of Brazil and to psychometrically validate it. Morgan's (1996) eight metaphors have served as the theoretical basis for formulating questions. The questionnaire was responded by almost 2.000 individuals, during two years, and it has been successively revised. Through the use of factor analysis, with oblique rotation, two perceived organizational images have been finally identified. The calculation of Cronbach's alpha scores has pointed out to adequate reliability indices for the safe use of the developed instrument in organizational research and analyses.
