Summary

Dissociative psychopathology is common in psychiatric inpatients, with average scores significantly higher than the general population. Approximately 6%-8% of these patients may have multiple personality disorder, indicating a need for awareness.

Area of Science:

  • Psychiatry
  • Psychology

Background:

  • Dissociative disorders are a spectrum of conditions characterized by disruptions in memory, identity, emotion, perception, and behavior.
  • These disorders are often underdiagnosed, particularly in inpatient psychiatric settings.

Purpose of the Study:

  • To investigate the prevalence of dissociative psychopathology in general adult psychiatric inpatients.
  • To estimate the potential occurrence of multiple personality disorder (MPD) within this population.

Main Methods:

  • The Dissociative Experiences Scale (DES) was administered to 299 inpatients on an acute care general adult psychiatric ward over a two-year period.
  • Analysis included calculating average scores and identifying individuals with very high scores (above 50) on common DES items.
  • A specific scale factor, 'Activities of Dissociated States,' was used to estimate MPD prevalence.

Main Results:

  • The average DES score for inpatients was 14.6, significantly exceeding the general population mean.
  • Approximately one in six inpatients reported very high scores, suggesting significant dissociative psychopathology.
  • An estimated 6%-8% of general adult inpatients may have multiple personality disorder.

Conclusions:

  • Dissociative psychopathology is highly prevalent in acute care general adult psychiatric inpatient units.
  • The findings underscore the importance of screening for dissociative disorders in this clinical population.
