Spectrum is just a word professionals use instead of the word "scale".

The diagnosing criteria of each dissociative disorder that professionals use is on a scale of 1-10.

based on where the person scores on their diagnostic testing of the validity scales and so on that are contained with in the tests like DDIS, DES and others (some interview and some computerized) is where they fit on that scale.

For example LL told me that I am probably an 8 or a 9 on the Dissociative Identity Disorder disoociative scale.

You can find out where you are on any of the dissociative disorders scales by taking a comprehensive psychological evaluation with suplimental tests for Dissociative Identity Disorder/dissociative disorders.

You can find in my blog in general terms what a comprehensive psychological evaluation is and contains though I did not include a complete list and details on all the tests given for DID. Some are not disclosed to the general public in part for the specific reason of weeding out the non - DID's.
