(Ridgeview Institute and the International Society for the Study of Multiple Personality and Dissociation, 1992-06) Ross, Colin A.; Anderson, Geri; Fraser, George A.; Bjornson, Lynda; Miller, Scott D.; Reagor, Pamela A.
The authors interviewed 166 patients with clinical diagnoses of multiple personality disorder and 57 with diagnoses of dissociative disorder not otherwise specified with the Dissociative Experiences Scale and the Dissociative Disorders Interview Schedule. The findings supported the concept of a spectrum of dissociation, with increasingly complex and symptomatic forms of dissociation related to increasingly severe childhood trauma.
