Quizplus · Accepted Answer

Dissociative identity disorder (DID) was not recognized as a distinct disorder until the publication of the third edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-III) in 1980. Prior to that, cases of DID were likely to be diagnosed as schizophrenia or other mental disorders. Therefore, it is unlikely that there were any reported cases of DID before 1970.
