Key clinical point: Schizophrenia spectrum disorders and aggression appear tied to difficulties in perceiving accurate emotion.
Major finding: Using measures such as the World Health Organization’s Schedule for Clinical Assessment in Neuropsychiatry 2.1, the investigators found that violent offenders with schizophrenia are less accurate at perceiving emotion, compared with controls (46.1 vs. 64.5%, P = 0.026).
Study details: The results are based on a cross-sectional study of 59 people with aggressive schizophrenia, compared with 88 controls.
Disclosures: The study was supported by several Swedish entities, including the Swedish Society of Medicine. The authors reported having no conflicts of interest.
