The Enneagram is a theory of personality typology developed within the Sufi school of Islam. While it has been preserved through oral tradition, little has been formally written about this system which offers heuristic insights into the structure and functioning of personality and is also employed as a diagnostic and therapeutic aid. This study undertook a systematic description of the Enneagram system, an assessment of the reliability of the typing of the system, an investigation into the concurrent validity of the system, and the construction of an objective test instrument to differentiate individuals into the nine personality types described by the system
Individuals were able to select one of the nine Enneagram personality types which best depicted their own personality style and to continue in their choice of that type after varying periods of time, ranging from four months to nine years. The subjects' self-perception and self-selection were stable enough to justify validation research
To assess the concurrent validity of the Enneagram system, subjects cognizant of their Enneagram type were administered the Millon-Illinois Self-Report Inventory and the Myers-Briggs Type Indicator. The results demonstrated highly significant differences among the nine Enneagram types and their scores on both the Millon and Myers-Briggs scales. The composite personality portrait was consistent with the Enneagram type descriptions. Although all three approaches relied on self-report measures, the substantial amount of agreement among the results yielded both convergent and discriminant validity and warranted the pursuit of further external validation
Along with the personality dimension, a highly significant age factor was found to be contributing to the results of the Millon and Myers-Briggs inventories. While this discovery was not anticipated, it indicated fertile possibilities for future research
The Enneagram Personality Inventory was devised to discriminate individuals into the nine types. There was a moderate amount of inter-item consistency within the nine scales and the predictive validity of the inventory offered a modest improvement over chance. Since there were both practical and theoretical benefits involved in the construction of such a test, suggestions were advanced for refining the reliability and predictive validity of this instrument
Recommendations were made for broadening the representativeness of the sample, for conducting a longitudinal study, and for exploring the subtypes found within each of the nine major Enneagram personality types
