By: David Daniels, Virginia Price

Narrated by: Lisa Larsen

The First Scientifically Determined Enneagram Personality Test and Guide

A centuries-old psychological system with roots in sacred tradition, the Enneagram can be an invaluable guide in your journey toward self-understanding and self-development. In this book, Stanford University Medical School clinical professor of psychiatry David Daniels and counseling psychologist Virginia Price offer the only scientifically developed Enneagram test based upon extensive research combined with a self-discovery and personal-development guide.

The most fundamental guide to the Enneagram ever offered, this book features effective self-tests to determine simply and accurately what your personality type is. Daniels and Price provide step-by-step instructions for taking inventory of how you think, what you feel, and what you experience. They then guide you in your discovery of what your type means for your personal well-being and your relationships with others, and they show you how to maximize your inherent strengths. Brimming with empowering information for each of the nine personality types—Perfectionist, Giver, Performer, Romantic, Observer, Loyal Skeptic, Epicure, Protector, and Mediator—this one-of-a-kind book equips you with all the tools you need to dramatically enhance your quality of life.

PDF Updated December 2025

Looks like the PDF to accompany the audio script was updated by Harper Audio in December 2025! The audio and PDF Test Booklet align and flow nicely. Lisa Larsen's voice is clear and describes the concepts well. The book is non-fiction so the content ('story') all holds together.

The PDF did not contain all of the information that is continuously referenced through this book, making it completely worthless

You guys really need to update this PDF. If it’s telling me to reference certain pages those pages need to be contained within the PDF.
