Summary

The dissociative taxon, proposed to identify pathological dissociation, was studied. Taxon membership was more frequent in patients but did not correlate with a clinical diagnosis of dissociative disorder.

Area of Science:

  • Psychology
  • Psychiatry
  • Clinical Psychology

Background:

  • Pathological dissociation is a clinical concern.
  • A 'dissociative taxon' was proposed to identify individuals with pathological dissociation.
  • The validity and frequency of this taxon require empirical investigation.

Purpose of the Study:

  • To determine the frequency of dissociative taxon membership in clinical and non-clinical populations.
  • To assess the validity of the dissociative taxon in relation to diagnosed dissociative disorders.
  • To clarify the clinical significance of belonging to the dissociative taxon.

Main Methods:

  • Utilized the Dissociative Experiences Scale (DES) for initial screening.
  • Administered the Dissociative Disorders Interview Schedule to patients with high DES scores.
  • Classified participants into the dissociative taxon based on established criteria.

Main Results:

  • Dissociative taxon classification applied to 2.9% of non-patients and 12.7% of psychiatric inpatients.
  • No statistically significant association was found between taxon membership and a formal diagnosis of a dissociative disorder.
  • Higher DES scores were observed in individuals classified within the taxon.

Conclusions:

  • While taxon membership is associated with increased dissociative experiences, it does not equate to a clinical diagnosis of a dissociative disorder.
  • The dissociative taxon may serve as an indicator of heightened dissociative symptomatology rather than a diagnostic classification.
  • Further research is needed to refine the utility of the dissociative taxon in clinical settings.
