OBJECTIVEThis study aimed to compare the prevalence of mental disorders and services for people with mental health problems in Shaoxing city between 1991 and 2001 in order to provide scientific bases for prevention and treatment.

METHODSA population size of 339 651 were investigated in the urban and rural areas with "Psychosis Index Investigate Schedule" plus visit to their homes.

RESULTSThe overall prevalence rates of mental disorders were 10.17 per thousand and 13.85 per thousand and the point prevalence rates of mental disorder were 9.15 per thousand and 12.77 per thousand, respectively in 1991 and 2001. The point prevalence rates in the population aged 15 years and above were 11.70 per thousand and 14.60 per thousand. Prevalence rates of neurosis and alcohol dependence and drug dependence increased significantly from 1991 and 2001. The anterior three mental disorders were neurosis, schizophrenia and dementia in all mental disorders. Situation was better in the city than in the rural areas in terms of receiving care for mental disorder, their work ability, economy condition and gardianship.

CONCLUSIONThere was an increase of prevalence on mental disorder in Shaoxing city during the ten-year period. The increase in the prevalence of mental disorder was related to local economy, socialization and culture.

We have not yet had any official diagnostic system of mental disorders that is specific for the elderly patients. As in other diagnostic categories, the DSM-IV and ICD-10 are used as the official diagnostic criteria for mood disorder. Several dichotomous classifications are, however, applied sometimes for clinical and research convenience. The reported prevalence rates of depressive symptoms are between 10-40% among the elderly residing in community;the rate is far higher among those who are hospitalized or in chronic institution. The prevalence of major depression, clinical depression, among the elderly is known to be lower than that among younger adults, the exact reason for which is not well clarified so far. The rate of dysthymia is around 1.7% and similar to that for general population. Poor social support network is the most well known risk for developing depression for the elderly.

OBJECTIVE: To explore the mental health condition of primary and middle school students in Changsha and to provide reference for future evaluation or intervention. METHODS: Strengths and Difficulties Questionnaire (SDQ) (the edition for parents) was used to investigate 737 primary and middle school students aged 6-17 in Changsha. RESULTS: The prevalence of difficulty was 14.11%. The males showed higher scores of problem, hyperactivity and impact, while the females scored higher in emotional symptom as well as prosocial behaviors. Students aged 11-13 and 14-17 showed higher scores of total difficulties, peer problems and emotional symptom than those aged 6-10. Apart from higher scores of total difficulties and peer problems, the other scores were similar to the normal scores in China. there was significant difference in the normal scores between china and other countries. CONCLUSION mental health problems have divergent characters in gender and age. This study also highlights the importance of establishing local norms of SDQ and the need for appropriate measures in practical situations.

It is well-known that more than 50% of attention-deficit hyperactivity disorder (ADHD) cases also have comorbid psychiatric disorders. We evaluated the comorbid psychopathology of Korean children and adolescents with ADHD using a standardized diagnostic instrument. The Korean Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version (K-SADS-PL-K) was administered and completed in 105 patients who had been referred to the outpatient and inpatient clinics at the Samsung Medical Center from March 2004 to May 2005. All of the cases were diagnosed as ADHD according to DSM-IV criteria. We analyzed their clinical characteristics and psychiatric comorbidities, and assessed the correlation of any comorbidity with gender, age and ADHD subtype. Among our 105 participants, 70 (66.7%) subjects were diagnosed with combined-type ADHD, 22 (21.0%) were the predominantly inattentive type, only 1 (1.0%) was determined to have the predominantly hyperactive-impulsive type of ADHD, and 12 (11.4%) were classified as not otherwise specified (NOS) ADHD. Eighty (76.2%) subjects had at least one comorbid disorder such as oppositional defiant disorder (n = 53, 50.5%), anxiety disorders (n = 35, 33.3%) and affective disorders (n = 15, 14.3%). Our patients ranged in age from five to 16 years. Among the factors including gender, age, and ADHD subtype, ADHD subtype was the only one significant to comorbidity in our study. The results of this study suggest that psychiatric comorbidity in Korean children with ADHD is similar to the results of previous studies in western countries. Out of all the ADHD subtypes, the combined-type group had a significantly higher ratio of comorbid disorders and psychopathologies.

OBJECTIVES: This study aims to develop a Korean version of the Composite International Diagnostic Interview(K-CIDI). METHODS: The Composite International Diagnostic Interview(CIDI) is a comprehensive, fully standardized interview that can be used to assess psychiatric disorders and provide diagnoses. The K-CIDI was developed according to the guidelines provided by the WHO. The reliability and validity of the K-CIDI was evaluated by examining 135 psychiatric patients and five community residents. Subjects were jointly interviewed twice with a one-week interval. A psychiatric resident and clinical psychologist jointly determined clinical diagnoses using the Structured Clinical Interview for DSM-IV. RESULTS: Notable modifications were done in sex-related expression, health system and help-seeking behavior, subjects for phobic disorder, and kinds of alcohol and substance. Long and complex questions were divided into two or more questions. Field test and back-translation of the K-CIDI confirmed the appropriateness of the translation of the CIDI. The inter-rater reliability, test/retest reliability, and validity of the K-CIDI indicated kappa values ranging from 0.86-1.00, 0.42-0.89, and 0.50-1.00, respectively. CONCLUSION: The K-CIDI was deemed to be appropriate for the sociocultural background of Koreans. The reliability and validity of the K-CIDI were judged to be exceptionally acceptable.
