Abstract

Introduction: The Enneagram is an old process for human personality typing, principally understood, and taught as a typology of nine interconnected personality types. The aim of this study was to develop a Turkish assessment tool based on the Enneagram principles.

Methods: An instrument based on expert opinion and the Delphic method was developed. The final questionnaire consisting of 27 questions, was applied to a sample of 199 Turkish-speaking participants. Expert validation, convergent validity, test-retest, and internal consistency were applied. Its categorization was validated against the personality type classification made by an expert and another Turkish inventory, the Ta????tan Personality Inventory.

Results: Of the participants, 70 were females (35.2%), and 129 were males (64.8%). The mean age of the participants was 34.26 ± 12.33 years. Cronbach’s alpha value for the total items was 0.756. The sensitivity and specificity of the results of the present study in detecting the different personality types ranged from 71.4% to 100.0%. Its overall performance was calculated as 90.8%.

Conclusion: It can be concluded that the Nile Personality Assessment Tool (Nile Enneagram Personality Test) is a useful tool in identifying personality types according to the Enneagram principles in Turkish-speaking people.
