OBJECTIVE: We aimed to investigate the predictive factors of violent behavior in schizophrenia and the relationship between violent behavior and insight and cognitive functions in this study.
METHOD: 68 patients diagnosed with schizophrenia were separated into two groups; with a history of violent behavior (n = 30) and without (n = 38). Both group swere administered the Positiveand Negative Syndrome Scale (PANSS), Buss-Perry Aggression Questionnaire, Schedule for Assessing the Three Components of Insight, California Verbal Learning Test (CVLT), Trail Making Test, Wisconsin Card Sorting Test, and Stroop Test.
RESULTS: Male gender, the number of hospitalizations, incompliance with the treatment, alcohol and substance abuse, the number of suicide attempts, the mean score of PANSS positive symptoms, PANSS general symptoms and PANSS total were significantly higher in patients with schizophrenia with a history of violent behavior, compared to non-violent group. Long delayed response subsection of CVLT mean score was lower in patients with violent behavior. Incompliance with the treatment (OR:5.927, p=0.041), alcohol and substance abuse (OR:21.089, p=0.000), and PANSS total score (OR:1.053, p=0.011)were identified as predictive factors of violent behavior in patients with schizophrenia.
CONCLUSION: Lack of insight and executive function impairment are the core symptoms of schizophrenia and not seems to be associated with violent behavior in patients with schizophrenia. Impairment of memory may be associated with violent behavior in patients with schizophrenia. Incompliance with treatment, alcohol and substance abuse, and the severity of positive symptoms are important factors in predicting violence behavior in patients with schizophrenia.
