Abstract
An individual's perceptions concerning their validity in the workplace, whether realistic or not, become the reality for the individual, and can have important consequences on the resulting organizational behavior of that individual. This paper examines the self-perceptions of an individual and analyzes the relationship of self-efficacy and perceived organizational support with the impostor phenomenon in the workplace. The results of the study of 588 employees at a southeastern university indicated an inverse relationship that does exist between the impostor phenomenon and self-efficacy as well as the impostor phenomenon and perceived organizational support. Implications and future research suggestions are also recommended.
