Resumen:
The most widely-used model in studies of organizational commitment is the three-dimensional model developed by Meyer and Allen in 1991. This model understands the construct as being composed of instrumental, affective, and normative dimensions. However, it has been criticized by researchers who do not view instrumental commitment as related to the concept of commitment, but instead as a possible organizational link. In order to address the conceptual and empirical problems of the instrument, Powell and Meyer perfected the sub-scale of instrumental commitment and recommended that a new scale, named Perceived Sacrifices Associated with Leaving, be used in future research. This article aims to adapt and obtain evidence of the validity of the new scale, and analyze how teachers perceive the sacrifices associated with leaving a Federal Institute of Education, Science, and Technology. The scale has undergone cross-cultural adaptation and the adapted version was applied to teachers. Exploratory Factor Analysis and Confirmatory Factor Analysis were applied, displaying evidence of the validity of the construct for the Brazilian version. The results revealed that teachers agree on the high intensity level of the sacrifices associated with leaving, and that teachers who occupy management positions perceive it to a higher degree than others. The proposed changes in the scale should be evaluated in future research, and other studies are important to confirm the results found.
