ABSTRACT
OBJECTIVES: This study aims to estimate the prevalence of the DSM-IV psychiatric disorders in Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI). METHODS: Subjects were selected by taking multi-stage, cluster samples of 7,867 adult household residents, 18 to 64 years of age, in ten catchment areas. Total 78 trained interviewers administered the K-CIDI to the selected respondents, from June 1 to November 30, 2001. RESULTS: Total 6,275 respondents completed the interview. Some 33.5% of respondents reported at least one lifetime disorder, 20.6% reported at least one-year disorder, and 16.7% reported at least one-month disorder. The most common lifetime disorders were alcohol abuse/dependence (17.24%), nicotine dependence/withdrawal (11.19%), specific phobia (5.16%), and major depressive disorder (4.25%). The lifetime prevalence of substance abuse/dependence (0.25%) and schizophrenia (0.16%) was very low. Nicotine and alcohol use disorder showed very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among female than male. CONCLUSION: The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in distributions of psychiatric disorders across the areas and times were observed.

OBJECTIVE: The types, contents and major themes of schizophrenic hallucinations in Shanghai and Seoul were compared for evaluating cultural differences and connotation. METHODS: Among the schizophrenic inpatients of Shanghai Mental Health Center in Shanghai and National Seoul Mental Hospital and Hanyang University Hospital in Seoul, 396 cases(182 cases in Shanghai, 214 cases in Seoul) were selected by two ways:a) five staged stratified random sampling of sex, age, education, clinical subtype and onset year, b) cases who have admitted for one to six months in their last admission. Among them, 231 cases(55.39% in Shanghai, 60.83% in Seoul) confirmed to have hallucinations were the final subjects of study. RESULTS: Frequencies in types of hallucination were not different between the two groups. However, contents and major themes were different:Political themes and related contents were dominant in Shanghai cases, and supernatural and religious themes and related contents were dominant in Seoul cases. CONCLUSION: It was concluded that contents and themes of hallucinations were closely related to the delusional contents and themes, and such patterns were considerably influenced by sociocultural characteristics.

In this transcultural study of schizophrenic delusions among patients in Seoul, Shanghai and Taipei, we discovered that both the frequency and content of delusions differed among the three groups; and that these differences could perhaps be explained by varying sociocultural and political situations. Delusional themes that are sensitive to sociocultural or political situations include guilt, love/sex, religion, somatic damage, economy/business and politics. Delusions regarding longevity, love/sex, dysmorphophobia/dysosmophobia, religion or supernatural matters, and espionage/spy stories were most frequent in Seoul patients. Those in Taipei predominantly had delusions about possession, religion or supernatural matters, hypnotism, and mass media/computers. Shanghai patients often had delusions of poisons, being prickled by poisoned needles, their brain and viscera extracted and being a family member of political authorities.

An association study with Korean schizophrenic patients(N=84) and normal controls(N=87) was performed to find the relationship between catechol-o-methyltransferase(COMT) gene polymorphism and schizophrenia using polymerase chain reaction-restriction fragment length polymorphism. When we compared the allele and genotype frequencies of Bg/I COMT gene polymorphism in schizophrenics and normal controls, there was no significant difference between two groups. Our results do not support an association between the Bg/I polymorphism of COMT gene and schizophrenia.

Alleles , Genotype , SchizophreniaABSTRACT
An association study with Korean schizophrenic patients(N=75) and normal controls(N=87) was performed to find the relationship between D9S158 polymorphism and schizophrenia using polymerase chain reaction. Eight different alleles of a dinucleotide polymorphism on D9S158 locus were observed in both group. When we compared the frequencies of alleles between schizophrenics and normal controls, there was no significant difference between two groups. To increase homogeneity of schizophrenic group, we divided schizophrenic group by clinical phenotypes such as family history, negative and positive symptoms(PANSS), soft neurologic signs(NES-K) and DSM-lV diagnostic subtypes. Then we compared the frequencies of alleles among subgroups of clinical phenotypes, and there were no significant differences between subgroups(p>.05). Although our findings fail to provide an evidence of association between schizophrenia and D9S158 locus, further investigation of other loci that are linked to NMDA receptor gene may be needed in genetically homogeneous subgroups of schizophrenia.
