DDNOS is a dissociative disorder caused by childhood trauma, like DID, and OSDD. It stands for dissociate disorder not otherwise specified. It is defined by having characteristics of one or more dissociative disorders but not fitting into one category.

(This is a definition from a DDNOS system)
DDNOS systems are valid just like DID and OSDD systems are!
