The purpose of the study was to investigate the construct validity of the Enneagram Personality Type scale developed by factor analysis. The author built a conceptual framework for examining 9 personality type on the basis of Riso(1996) and on other related approaches in various literature reviews. This study developed Youn Enneagram Personality Type Indicators(YEPTI), which consists 9 personality types including the 81 items of the scale presented in a 5 point Likert format. The YEPTI was administered to 2179 participants, 559 males and 1620 females(1869 college students, 219 teachers, 61 company workers, and 30 soldiers).
The results of exploratory factor analysis by SPSS program showed that Enneagram personality type scale assumed to have 9 distinguishable latent factors: reformer, helper, performer, individualist, observer, loyal-skeptic, generalist, leader, and peacemaker. The means, standard deviations, of the subtests of YEPTI are reported. The alpha coefficients of the instrument ranges from .51 to .80, and the test-retest reliabilities(2-week interval) ranges from .67 to .92. Thus, it could be concluded that each of the scales was accepted as representing a good fit to one factor model. Thus, it may by utilized as a reliable psychological instrument for understanding one's personality types in school education and guidance. However this scales should be valid through specification search processes in terms of the ecological population validity.
