Abstract

The purposes of the study were to identify the personality traits differences of the NEO-PI-R between the each of the patient groups and the normal group, and to explore the NEO-PI-R profiles of the patient groups, that were diagnosed alcoholism, depression, or schizophrenia by the psychiatrists. The patient groups were the high level in the Neuroticism and the low level in the Openness to Experience with the comparison to the normal distribution. Data analyses indicated that there were mean differences between the depression group and the normal group in the Neuroticism, Extraversion, and Openness to Experience domains. There were mean differences between the schizophrenia group and the normal group in the Extraversion and Openness to Experience domains. And there were mean differences between the alcoholic group and the normal group in the facets of the four factors with the exception of the Neuroticism domain. The profiles of the NEO-PI-R Korean version are as follows- The alcoholic patient group were explained according to the high 'E(Extraversion)' and low 'O(Openness to Experience)' pattern. The depression patient group were explained according to the high 'N(Neuroticism)' and the low 'O' pattern. The schizophrenia patient group were explained according to the low 'E' and low 'O' pattern. Overall, these results indicates the personality traits of the NEO-PI-R can anticipate clinical symptoms. So the NEO-PI-R Korean version may be useful to clinicians in understanding the patient, formulating a diagnosis, establishing rapport, and selecting the optimal form of treatment for the patient.
