Development of the OSPP Enneagram of Personality Scales

This page serves as documentation for the OSPP Enneagram of Personality Scales.

Background

The Enneagram of Personality is a model of personality with nine personality types. The theory has been developed and promoted by many different people and groups over the years, so there is no definitive test.

Initial item screening

The first alpha version of the test contained 72 items that were generated by the test creator after reading descriptions of the nine types in various different sources. This early version of the test
