Why none of these give you a score
Because a number is a thing to come back and check. Searching your own theme, reading one more account of it and retaking the quiz to see whether it moved are all the same move as asking somebody to tell you it is fine, and the relief they buy runs out at about the same speed.
So these ask what you do rather than how bad it is, and what comes back is what you said instead of a verdict. The published measures work the same way: not one of the eighteen items on the OCI-R asks what a thought is about, and even scored properly by a clinician it does not diagnose anybody.
If you want the whole loop rather than one theme, the free check is seven questions and about two minutes.
