Abstract

Objectives：The aim of this study was to assess dimensions of temperament and character in homicidal schizophrenic patients by using the temperament and character inventory(TCI) which was defined based on Cloninger’s biosocial model.
Subjects and Methods： Eighty four homicidal schizophrenic patients and 100 non-homicidal schizophrenic patients and 61 normal controls participated in this study. We used the Korean version of the TCI to compare these 3 groups. Diagnostic evaluation was made with Structured Clinical Interview for DSM-Ⅳ(SCID), and symptom evaluation was made with Positive and Negative Syndrome Scale(PANSS), and violent behavior was assessed with Life History of Aggression(LHA).
Results：Novelty seeking(NS) was lower in homicidal schizophrenic patients(HS) than non-homicidal schizophrenic patients(NHS)(p=0.01). Harm avoidance(HA) and Self-transcendence(ST) were higher in two schizophrenic patients groups(HS, NHS) than normal control(p<0.01). In two schizophrenic patients groups(HS, NHS) Reward dependence(RD) and Self-directedness(SD) and Cooperativeness(C) were lower than normal control(p<0.01).
Conclusion：The author found that higher NS was not a characteristic of homicidal schizophrenic patients comparing with non-homicidal schizophrenic patients. This study replicates the results of previous studies suggesting that schizophrenic patients have high HA and high ST.
