Introduction: “An exaggerated sense of self-importance”, which starts with claiming rights, sense of arrogance and superiority; and which is strengthened with compulsion and lack of empathy, is the first sign of pathology. A high correlation was found between narcissistic personality and the state that is conceptualized by some writers as “inflated sense of self”. Aim: This study is aimed at developing a scale that can measure dimensions and levels of the Exaggerated Sense of Ego and can be used by psychologists, psychological counselors and researchers as a unique measuring tool in Turkish. Methods: 1433 people voluntarily participated in this four-stage study. Dark Triad, Levenson Psychopathy Scale, Narcissistic Personality Inventory and Zuckerman-Kuhlman Personality Test were used to test the coherence of the scale. The data analysis was implemented by the means of Kaiser-Meyer-Olkin coefficient, Barlett Sphericity Test, exploratory and confirmatory factor analysis and correlation and regression techniques. Results: At the end of the study four-dimensional structure of the scale was proved; it was confirmed that the four dimensions appear to be the components of the structure that is called exaggerated sense of ego and create the upper-structure altogether. Goodness of fit index of the model was also found to be high. Cronbach Alfa internal consistency coefficient has shown between .76 and .79 for four dimensions, while internal consistency coefficient of the whole scale has shown .90. Correlation and predictive power were also high in compliance validity tests that were implemented with the 4 scales. Conclusion: The developed Scale of Exaggerated Sense of Ego is a measuring tool that can be safely used by psychologists, psychological counselors and researchers.
