The association between dissociative symptoms and schizophrenia-related negative symptoms: A transdiagnostic approach


Levin, Yafit; Bachem, Rahel; Brafman, Dorit; Ben-Ezra, Menachem (2024). The association between dissociative symptoms and schizophrenia-related negative symptoms: A transdiagnostic approach. Journal of Psychiatric Research, 169:81-83.

Abstract

Negative symptoms of schizophrenia remain clinically and theoretically understudied and represent an unmet psychiatric need. Negative symptoms are assumed to be related to other psychiatric disorders, but their association with dissociative symptoms is yet to be explored, particularly in light of depression and anxiety symptoms. We examined the five domains of negative symptoms (anhedonia, asociality, avolition, blunted affect and alogia) in an Israeli national sample of 1930 participants of whom 645 (33.4%) were with increased risk for dissociative disorder. The results show that anhedonia, blunted affect and alogia significantly associated with risk for dissociative disorder, above and beyond depression and anxiety. When assessing for negative symptoms it may be worth screening for dissociation and vice versa and thus make a more accurate clinical picture of the interplay between them.
