Abstract:
OBJECTIVES: We attempted to investigate personality characteristics influencing insight acquisition in patients with schizophrenia. METHODS: Tridimensional personality questionnaire(TFQ) for neurobiologically based personality characteristics assessment and Barron's ego strength test were administrated to 30 patients with schizophrenia who had good insight and 30 patients who had poor insight. Each group was also compared with 453 normal health controls. RESULTS: There were no significant differences between good and poor insight acquisition groups on ego strength. Poor insight acquisition group showed significantly higher reward dependence dimension on Tridimensional Personality Questionnaire than good insight acquisition group, though the other two personality dimensions showed no difference. The good insight group showed no difference on three TFQ dimensions from normal healthy control group. However, the poor insight group demonstrated higher score in reward dependence dimension than the healthy control group but not in the other two dimensions. CONCLUSION: These results suggest that neurobiologically determined personality characteristics rather than ego strength would be closely related with insight acquisition in schizophrenia. Reward dependence as groups of behavioral characteristics, mainly derived from central norepinephrine mediated behavior would be related with insight formation. The roles of norepinephrine in schizophrenia have not been lolly understood yet. Further understandings regarding insight formation process and role of norepinephrine In schizophrenia could give some clues on insight acquisition in patients with schizophrenia.
