Empirical testing of criteria for dissociative schizophrenia.

This study examined the validity of dissociative schizophrenia diagnostic criteria. In the first phase, 50 participants with a psychotic disorder were administered the Dissociative Experiences Scale and the Childhood Trauma Questionnaire to identify those with dissociative characteristics. In the second phase, we selected those who had a score of 15 or above on the Dissociative Experiences Scale.

[Does dissociative schizophrenia exist?].

On a phenomenological level, there's an important overlap between dissociative and psychotic symptoms. Furthermore, traumatic etiology, recognized in dissociative disorders, is also increasingly considered in psychosis. These similarities create confusion in clinical settings with important repercussions for individuals suffering from these disorders.
