Dissociative identity disorder (DID) and schizophrenia-spectrum disorders (SSD) share some overlapping phenomenological features making accurate diagnosis more difficult. Childhood abuse depersonalization have been associated with psychotic symptoms across psychological but their relationship to phenomenology remains understudied.The present study used quantitative measures examine (1) similarities differences in voice hearing experiences, interpretations of voices, thought individuals DID (n = 44) or SSD 45), (2) whether childhood maltreatment influenced the initial pattern findings.DID participants perceived voices as being internally located generated, louder, uncontrollable than participants. Furthermore, endorsed a greater frequency symptoms. Adding covariates (sex, depersonalization, child maltreatment) did not change findings location origin derailment, there were now no loudness controllability. However, schizophrenia sample reported distress metaphysical beliefs well incoherence word substitution controlled.While tentative, incoherent thoughts may reflect processes.
