The free quiz on olively.app gives you a starting point in about two minutes. The Attachment Profile inside the app goes further. Its 40 questions cover eight facets of the two dimensions researchers measure, attachment anxiety and attachment avoidance, and the app writes a report on how you handle closeness and conflict and what you do when a partner pulls away.
You can take the report into a conversation with the coach, read the guide for your pairing, or keep it to yourself. If you want to show someone, you can publish it at a private link and unpublish it whenever you like.
