Enneagram Personality Test

The Enneagram's modern psychological application emerged from the work of Oscar Ichazo and Claudio Naranjo in the 1960s and 1970s. Naranjo, a psychiatrist trained at Harvard and Berkeley, integrated the system with contemporary personality psychology and introduced it to the therapeutic community.

While the Enneagram has roots in various wisdom traditions, recent empirical research has begun to validate its constructs. A 2021 study in the Journal of Clinical Psychology found that Enneagram types showed meaningful correlations with DSM-5 personality disorder traits, suggesting clinical utility.

Researchers at Stanford University and the University of California have examined the Enneagram's relationship to established personality measures. Studies show moderate correlations with Big Five traits, though the Enneagram's focus on core motivations provides distinct information not captured by behavioral trait measures.

The Enneagram Institute has conducted internal reliability studies showing Cronbach's alpha values above 0.70 for their typing instrument, the RHETI. While more peer-reviewed research is needed, the system has gained acceptance in organizational psychology, with over 70% of Fortune 500 companies reportedly using it for leadership development.
