Prevalence of Undiagnosed Dissociative Disorders in an Inpatient Setting

This study examined the prevalence of undiagnosed dissociative disorders in a sample of 201 adult patients admitted to a private psychiatric hospital in a major metropolitan city in the south-central United States, over an eight-month period. A screening measure, two blind structured interviews, and a blind clinical interview were employed. The lifetime prevalence of dissociate disorders among the interviewed subjects was 40.8%. More specifically, 7.5% were diagnosed with dissociative identity disorder, 15.4% with dissociative disorder not otherwise specified, 13.4% with dissociative amnesia, and 4.5% with depersonalization disorder. Dissociative fugue was not found in this sample. Cohen's kappa reliability coefficients were computed between the three interview measures, resulting in significant findings for the presence of dissociative identity disorder and dissociative disorder not otherwise specified versus no dissociative disorder. The Cohen's kappa reliability coefficients were as follows: DDIS-DES-T = 0.81; SCID-D-DES-T = 0.76; Clinician-DES-T = 0.74, DDIS-SCID-D = 0.74; DDIS-Clinician = 0.71, and SCID-D-Clinician = 0.56. A meeting was conducted at the end of all subject interviews to discuss discrepant findings between measures. Four additional sub-analyses were performed between dissociative and non-dissociative subjects on DSM-IV variables. Patients diagnosed with a dissociative disorder had higher rates of comorbid major depressive disorder, borderline personality disorder, somatization disorder, and childhood history of physical and/or sexual abuse. Theoretical and methodological issues were discussed as they relate to these findings.
