Multiple personality disorder (MPD), now known as dissociative identity disorder, is more common than previously believed. This study found that 4.4% of general adult inpatients had MPD, suggesting a need for increased awareness and diagnostic efforts.

Area of Science:

  • Psychiatry
  • Psychology
  • Mental Health

Background:

  • Multiple personality disorder (MPD) was historically considered a rare condition.
  • Recent evidence suggests MPD may be more prevalent in the general population than previously assumed.

Purpose of the Study:

  • To investigate the prevalence of MPD in a general adult inpatient population.
  • To discuss the implications of MPD prevalence on diagnosis and treatment.

Main Methods:

  • Retrospective analysis of 73 inpatient admissions over one year.
  • Inclusion of previously undiagnosed cases in an unselected general adult population.

Main Results:

  • Eight out of 73 (11%) inpatient admissions were for MPD.
  • Excluding pre-diagnosed MPD cases, 4.4% of inpatients had MPD.
  • Three of the MPD admissions were previously undiagnosed cases.

Conclusions:

  • MPD appears to be relatively common in general adult inpatient settings.
  • Findings suggest a potential underdiagnosis of MPD.
  • The study highlights the need for improved diagnostic strategies and awareness among clinicians.
