Objectives: The aim of this study was to investigate the comorbidity of dissociative disorders in patients withbipolar disorder.Methods: Fifty-one patients who are diagnosed with bipolar disorder in euthymic state and forty-nine healtycontrols were included in the study. The Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I),Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D), Dissociative Experiences Scale(DES) and Childhood Trauma Questionnaire (CTQ-28) were administered to all participants with asociodemographic form.Results: Mean DES and CTQ-28 total scores were statistically higher in patients group than control group (p< 0.001 and p < 0.001, respectively). Emotional abuse, emotional neglect, physical abuse, physical neglectand sexual abuse subscale scores of CTQ-28 were higher in patients group than healthy controls group (p =0.002, p < 0.001, p = 0.005, p < 0.001 and p < 0.021, respectively). The rate of any dissociative disordercomorbidity was 35.4% in patients with bipolar disorder. The most frequent dissociative disorder in patientwith bipolar disorder was depersonalization disorder (17.6%). There was a positive correlation between DESscore and number of suicidal attempts (r = 0.284). Negative correlations were found between DES score andage of disease onset, and CTQ-28 total score and age of disease onset (r = -0.332 and r = -0.291).Conclusion: Our results have shown that dissociative disorders may be frequently accompanied in patientswith bipolar disorder. Dissociation and childhood traumatic events can be related with clinical features inpatients with bipolar disorder.
