Description: This study set out to explore the nature and existence of the impostor phenomenon, a subjective experience of intellectual phoniness demarcated by dissonance between an individual's public image of high achievement and internal feelings of incompetence. If the impostor phenomenon exits, it could be a major factor that keeps some people from fulfilling their true potential and have a negative impact on work performance and production.

To extend the impostor construct's validity and generalizability, past research by Harvey (1981) and Topping (1983) was replicated. A subject population removed from the academic setting was used--registered nurses. The data were collected by mailed questionnaires. The subject population comprised of 110 respondents.

In regard to discriminant validity, the results of this study lent support to the past finding that the impostor phenomenon was related but distinguishable from self-monitoring behavior. The relationship between self-esteem and the impostor construct was stronger than in previous research. This finding raises the questions of whether the Harvey IP Scale is an accurate measure of the impostor phenomenon or if the impostor construct is distinguishable from self-esteem.

This study further tested the impostor construct's discriminant validity by seeing if it was related to an individual's locus of control. Individuals who experienced strong impostor feelings tended to have an external locus of control. The statistical significance of the relationship was small. Thus the two constructs were separate and distinguishable. To gain a better understanding of the developmental aspects of the impostor phenomenon, this study explored its relationship to birth order. First-born individuals were more likely to experience a lower intensity of impostor feelings.

A Discriminant Analysis was performed with all demographic and characteristic variables to test their strength in distinguishing between individuals who experience strong and weak impostor feelings. Self-esteem, accounting for 65% of the explained variance, birth order (22%), years in current position (7.7%), effort success attributions (3%), and age (1.3%), were the first five variables that entered into the analysis. There was an 86% accuracy rate of impostor group prediction. General conclusions and suggestions for future research were presented.
