Enneagram Personality Test RHETI

 

Enneagram Infographic / Geoffrey W. Sutton, PhD

Scale name: Enneagram [Riso-Hudson Enneagram Type Indicator [RHETI®]

Scale overview: There is more than one version of the Enneagram, which purports to measure how an individual’s personality fits with nine types. The version referred to in this post is the RHETI®—see above for the full name.

A study by Newgent et al. (2004) used the 144-item forced choice format.

Authors: Don Richard Riso and Russ Hudson

Response Type: Forced-choice format

Subscales: 

Nine Enneagram types and descriptors

1 Reformer- principled, idealistic: purposeful, self-controlled, perfectionistic

2 Helper- caring, interpersonal type: people pleasing, generous, possessive

3 Achiever- success-oriented type: image-conscious, adaptive, driven

4. Individualist- sensitive, introspective type: expressive, dramatic, temperamental

5 Investigator- intense, cerebral type: perceptive, innovative, isolated

6 Loyalist- committed, security-oriented type: engaging, anxious, responsible

7 Enthusiast- busy, fun-loving type: spontaneous, distractible, scattered

8 Challenger- powerful, dominating type: decisive, willful, confrontational, self-confident

9 Peacemaker- easy-going, self-effacing type: agreeable, complacent, receptive

More detailed descriptions can be found at The Enneagram Institute

Sample item: (Newgent, et al., 2004, p. 228)

Item I contains the following two responses: "I've been romantic and imaginative" and "I’ve been pragmatic and down to earth." The first response is associated with the Individualist and the second response is associated with the Loyalist

Reliability: In their small study, Newgent et al. (2004) reported a range of alpha values from .56 (Achiever, Investigator) to .82 (Helper) six scales were at or above alpha .70.

 

Validity: Newgent et al. (2004) administered a version of the Big Five (NEO PI-R). They calculated correlations and performed a canonical variate analysis. They reported that all of the RHETI types were significantly correlated with at least one of the five NEO PI-R factors. See Table 1 for the details.

Notes

Hook et al. (2021) published a review of the literature on the Enneagram. They found mixed evidence regarding reliability and validity. Factor analyses yielded less than nine factors.

Several have found the Enneagram useful in spiritual growth. For example, see (Kam, 2018; Singletary, 2020).

In the SCOPES model, the Enneagram fits in the O = Observable behavior pattern of functioning.
