i did not ever receive any diagnosis based on a test of any kind.

i only had tests over the years to look for learning disabilities, anxiety, depression, cognitive functioning, and overall personality profile. they never picked up on dissociation as i don't believe that was something ever included on tests.

what led to my diagnoses of dissociative disorders including DID was based on a professional who was educated/knowledgeable on it and seeing it in me over the first few sessions/months of seeing them. it took longer though for me to talk about it, so it was only last year officially confirmed to me after several years of seeing them.
