For the most in-depth profile of your personality type, as well as the other eight types operating as psychological 'functions' in your personality, take the full-length, RHETI in booklet form. The Riso-Hudson Enneagram Type Indicator (RHETI, version 2.5) is a forced-choice test with 144 paired statements. It is the only independently validated Enneagram test (the result of two separate validation studies). The RHETI provides scores for all nine types in a full-spectrum profile, and access to the Expanded Personality Type Descriptions (of over 5,000 words each).
