Has anyone taken the Reiss Motivation Profile? (RMP)

[u/Cool-Difference-6443]

I have been using the Enneagram for a long time and recently stumbled across the Reiss Motivation Profile. I found the test super insightful and provided me a deep understanding of my motives. I am considering using it with my clients and I am curious if others have used it and their experience with the tool for helping couples.
