The phenomenon of aggression in individuals with schizophrenia

Abstract

Objective: to compare and identify differences in the psychopathological symptoms and domains of social cognition in groups of individuals suffering from schizophrenia with a high level of aggression with or without alcohol consumption.Materials and methods. In the period from 2014 to 2020, we performed a comparative, cross-section, one-stage, observational study with the formation of a sample by the method of directed selection at Gomel Regional Clinical Psychiatric Hospital. The following assessment methods were used: 1. Screening for alcohol use — ASSIST scale (Humeniuk R. et al. 2008), 2. Determination of the level of aggression — OAS scale (Yudofsky SC 1986), 3. Degree of severity of psychopathological symptoms — PANSS scale (S. Kay, L.Opler 1986), 4. Hostile attributive style of the AIHQ scale (Combs D. R. et al., 2007). 5. The research of emotional processing was performed using a computerized neuropsychological battery (PennCNP) to study the neuropsychological functioning of the Laboratory of Brain Problems of the University of Pennsylvania.Results and discussion: The group with a preclinical level of alcohol consumption revealed changes in emotional processing (″reduced facial memory″), a bias in the attributive style towards hostility, and changes in the psychopathological symptoms, such as an increase in ″emotional lability″ and ″decreased judgment and awareness of the disease″. In the group without alcohol consumption, an increase in ″false positive recognition of neutral emotions″ and an increase in the degree of manifestation of the symptom of ″delusion″ were revealed.Conclusion: Alcohol and aggression are in conjunction with the psychopathological symptom ″emotional lability″ (PANSS scale) and the domain of social cognition ″attributive style″ (″anger index″). In the group without alcohol consumption, aggression is related to the ″delusion″ symptom.
