Dissociative Disorders

Abstract Major dissociative disorders inDSM‐5include dissociative amnesia, depersonalization/derealization disorder, and dissociative identity disorder. The trauma model and the sociocognitive model are two perspectives that vie for empirical support as explanations of the genesis of dissociative identity disorder and perhaps other dissociative disorders. Nevertheless, there have been increasing signs of convergence between the trauma and sociocognitive models, and a more recent sleep‐trauma model represents an attempt partly to integrate them. Medication does not appear to be effective in treating dissociative disorders, and psychotherapies await evaluation with rigorously controlled clinical trials.
