The aim of the current study was to explore how the social stigmatization of dissociative identity disorder (DID) compared to that of schizophrenia and depressive disorders. Using a between-subjects experimental design, a total of 139 participants (126 usable data [39 men, 84 women, 3 other]) from the general population were randomly assigned to either a DID, schizophrenia, or depressive disorders experimental condition and responded to an adapted version of the Prejudice Toward People With Mental Illness (PPMI) Scale. Results suggested that, overall, depressive disorders were stigmatized against the least, schizophrenia was stigmatized against the most, and DID was intermediate, with its PPMI score being closer to schizophrenia than that of depressive disorders. We also found the same pattern for most of the subscales of the PPMI. At least relative to other well-known disorders, there is negative stigma associated with having DID.
