Objective : Psychopathy has been suggested as one of the important cause of violence in patients with schizophrenia. The purpose of this study was to evaluate the personality disorder in criminal schizophrenia.
Methods : A total of 187 criminal schizophrenia participated in this study. All participants filled out the Korean Inventory of Interpersonal Problem Personality Disorder Scales (K-IIP-PD), Psychopathic Personality Inventory-Revised (PPI-R), Personality Assessment Inventory (PAI). Using the correlations between the scales, we investigated whether K-IIP-PD could be used to evaluate personality disorder in criminal schizophrenia. Moreover, participants were divided into two groups of psychopathic and nonpsychopathic schizophrenics, and scores of K-IIP-PD were compared between the two subgroups.
Results : The overall correlation between the scales was very high. In particular, sum of 3 item scores (interprsonal sensitivity+interpersonal ambivalence+aggression) and aggression of K-IIP-PD were highly correlated with PPI-R and PAI. Total score of personality disorder scale and subscales were higher in psychopathic schizophrenic group compared to nonpsychopathic schizophrenic group.
Conclusion : The K-IIP-PD could be used to assess the antisocial and aggressive nature of criminal schizophrenia. Further studies in various clinical groups including the general population are required.
