Wearne, D., Curtis, G.J., Genetti, A., Samuel, M. and Sebastian, J. (2017) Where pseudo-hallucinations meet dissociation: a cluster analysis. Australasian Psychiatry, 25 (4). pp. 364-368.

Abstract

Objectives:
The possible link between cognitive areas of perception and integration of consciousness was examined using assessments of hallucinations and derealisation/depersonalization.

Methods:
Sixty-five subjects in three main diagnostic groups – posttraumatic stress disorder (PTSD), borderline personality disorder (BPD) and schizophrenia – identified by their treating psychiatrist as hearing voices were surveyed regarding characteristics of hallucinations, derealisation/depersonalization, delusions and childhood/adult trauma.

Results:
A cluster analysis produced two clusters predominantly determined by variables of hallucinations measures, childhood sexual abuse and derealisation/depersonalization scores.

Conclusions:
History of childhood trauma and variability in derealisation/depersonalization scores were better predictors of external, negative, uncontrollable voices than diagnosis of BPD or PTSD. The potential links between dissociative states and pseudo-hallucinations are discussed.
