This study aimed to verify the organization, consistency, and variation of the factorial structure of the Organizational Support Perception Scale (EPSO) among Brazilian workers. The economic, social, and professional changes that have occurred in recent years have influenced organizations in developing and maintaining people management practices focused on the quality of life of both the worker and the institution itself. Among the various proposals for the evaluation and diagnosis of organizational practices grounded in Positive Psychology, the assessment of organizational support has stood out as a relevant auxiliary measure of organizational performance. A total of 402 workers from the state of Rio Grande do Norte participated in the study, aged over 21 years and working in different professional specialties. Participants completed a sociodemographic questionnaire and the EPSO. For cross-validation purposes, the General Health Scale was also applied. Statistical analyses—including discriminant, representativeness, exploratory, and confirmatory analyses—revealed satisfactory psychometric indicators, confirming the quality of the measure. It can therefore be concluded that the scale is reliable for assessing the construct of organizational support among Brazilian workers. Moreover, the findings of this study support the possibility of developing a psychological test aimed at both organizational and individual evaluation.
