The Riso-Hudson Enneagram Type Indicator (RHETI) is a forced-choice personality test that has been scientifically validated and is comprised of 144 paired statements. This test takes about 40 minutes to complete and produces a full personality profile across all nine personality types. The forced-choice format yields information not only about the user's main personality type, but also about other major personality structures. This provides a unique portrait that indicates the relative strengths and weaknesses of the nine types within your overall personality. Authors Don Riso and Russ Hudson, 1999 Reliability and Validity The most recent validation study was done in 2009 by Mary Ann Giordano. It is the third independently conducted study of the RHETI and it corroborates the research done by Rebecca Newgent, Ph.D. back in 2001. Both studies concluded the instrument as scientifically "valid and reliable" as a test instrument with "solid psychometrics". The internal consistency reliability scores show that the RHETI ranges from 56% to 82% accurate on various types; with an overall accuracy of 72%. Since everything above 70% is acceptable, 72% is a solid score for a forced-choice test. Purchasing the RHETI Enneagram Institute Administration, Analysis and Reporting Statistics Solutions consists of a team of professional methodologists and statisticians that can assist the student or professional researcher in administering the survey instrument, collecting the data, conducting the analyses and explaining the results.
