    Patients with multiple personality disorder report significantly more somatic symptoms and a higher prevalence of somatization disorder compared to those with panic disorder, eating disorders, or schizophrenia.

    Area of Science:

    • Psychiatry
    • Psychology
    • Clinical Medicine

    Background:

    • Dissociative disorders, including multiple personality disorder (now known as dissociative identity disorder), are complex mental health conditions.
    • Somatic symptoms are physical complaints that may or may not be accompanied by a diagnosed medical condition.
    • The relationship between dissociative disorders and somatization requires further investigation.

    Purpose of the Study:

    • To compare the frequency of somatization disorder and individual somatic symptoms in patients diagnosed with multiple personality disorder versus other psychiatric conditions.
    • To investigate the prevalence of somatic symptoms within a sample of patients with multiple personality disorder.

    Main Methods:

    • A structured interview, the Dissociative Disorders Interview Schedule, was utilized.

  • The study included four groups of 20 patients each: multiple personality disorder, panic disorder, eating disorders, and schizophrenia.
  • Frequencies of somatization disorder and somatic symptoms were compared across the groups.

    • Main Results:

    • Patients with multiple personality disorder reported a higher number of somatic symptoms than patients in the other diagnostic groups.
    • Seven out of 20 patients with multiple personality disorder met the diagnostic criteria for somatization disorder.
    • The average number of reported somatic symptoms among multiple personality disorder patients was 13.5.

    Conclusions:

    • Multiple personality disorder is strongly associated with a high burden of somatic symptoms.
    • A significant portion of patients with multiple personality disorder may also meet criteria for somatization disorder.
    • These findings highlight the importance of assessing for somatic symptoms in the diagnosis and treatment of dissociative disorders.
