A Cross-sectional Survey of Disability Attributed to Mental Disorders and Service Use in China / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Mental disorders are strongly associated with disabilities. National survey on disability could provide a reliable basis for policymaking in care and rehabilitation of disabled persons. This study aimed to describe the disability prevalence rates attributed to mental disorders, their distribution by sociodemographic factors, and utilizations of service.</p><p><b>METHODS</b>This study is a secondary data analysis of the Second National Sample Survey on Disability in 2006. The disability and severity were assessed using the World Health Organization Disability Assessment Schedule 2.0. Mental disorders were diagnosed according to the International Statistical Classification of Diseases and Related Health Problems 10th Revision Classification of Mental and Behavioral Disorders. Using descriptive and analytic epidemiological methods, prevalence rates of disability attributed to mental disorders and service use were calculated.</p><p><b>RESULTS</b>Data of 2,526,145 respondents were analyzed. The disability prevalence rate attributed to mental disorders in China was 6.3‰, accounting for 9.9% of all disabled people. Regarding disability prevalence attributed to mental disorders, it showed that gender, residential area, marital status, education level, and economic area were related to the prevalence distributions. The proportions of mild disability were highest in the disabled people with onset age of 18-64 years, while the proportion of extremely severe disability was highest in the disabled people with onset age of 65 years and above. Only 58.6% of disabled people attributed to mental disorders used some of the services.</p><p><b>CONCLUSIONS</b>There are statistical differences of disability prevalence attributed to mental disorders by people and region in China. Service use in disabled people with mental disorders is insufficient.</p>

Distribution and Risk Factors of Disability Attributed to Personality Disorders: A National Cross-sectional Survey in China / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Personality disorders can lead to some disability. However, little is known about the disability prevalence and function impairments. This study aimed to describe the disability prevalence attributed to personality disorders, its distribution, impairments of daily activities and social functions, and risk factors in China.</p><p><b>METHODS</b>Using a descriptive and analytic epidemiological method, data from the Second China National Sample Survey on Disability in 2006 were analyzed. The disability prevalence attributed to personality disorders, its distribution in different people and regions, and risk factors were statistically calculated.</p><p><b>RESULTS</b>Respondents included 1,909,205 adults. The disability prevalence rate attributed to personality disorders in China was 5.9/100,000. The disability rate attributed to personality disorders of males was higher than that of females (P = 0.012), while the rate of the unemployed was higher than that of the employed (P < 0.001). Furthermore, the rates of unmarried/divorced/widowed people and the illiterate population were higher than those of married and educated people (P < 0.001). Regarding the severity of disability attributable to personality disorders, mild disability accounted for a majority or 60% of the respondents. The data showed that disability mainly impaired respondents' ability to engage in daily activities, get along with people, and participate in social situations. According to the case-control study, marriage, employment, and higher education were protective factors of disability.</p><p><b>CONCLUSIONS</b>The prevalence of disability attributed to personality disorders is low in China and always leads to mild disability. The distribution of disability attributed to personality disorders also varies in the Chinese population.</p>

Validity of Chinese Version of the Composite International Diagnostic Interview-3.0 in Psychiatric Settings / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The Composite International Diagnostic Interview-3.0 (CIDI-3.0) is a fully structured lay-administered diagnostic interview for the assessment of mental disorders according to ICD-10 and Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria. The aim of the study was to investigate the concurrent validity of the Chinese CIDI in diagnosing mental disorders in psychiatric settings.</p><p><b>METHODS</b>We recruited 208 participants, of whom 148 were patients from two psychiatric hospitals and 60 healthy people from communities. These participants were administered with CIDI by six trained lay interviewers and the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I, gold standard) by two psychiatrists. Agreement between CIDI and SCID-I was assessed with sensitivity, specificity, positive predictive value and negative predictive value. Individual-level CIDI-SCID diagnostic concordance was evaluated using the area under the receiver operator characteristic curve and Cohen's K.</p><p><b>RESULTS</b>Substantial to excellent CIDI to SCID concordance was found for any substance use disorder (area under the receiver operator characteristic curve [AUC] = 0.926), any anxiety disorder (AUC = 0.807) and any mood disorder (AUC = 0.806). The concordance between the CIDI and the SCID for psychotic and eating disorders is moderate. However, for individual mental disorders, the CIDI-SCID concordance for bipolar disorders (AUC = 0.55) and anorexia nervosa (AUC = 0.50) was insufficient.</p><p><b>CONCLUSIONS</b>Overall, the Chinese version of CIDI-3.0 has acceptable validity in diagnosing the substance use disorder, anxiety disorder and mood disorder among Chinese adult population. However, we should be cautious when using it for bipolar disorders and anorexia nervosa.</p>

Psychological symptoms and associated risk factors in Chinese freshmen: a three-year follow-up study / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The first year of attending university induces a stressful experience for many college students. The experience exposes these students to challenging circumstances and raises expectations, which consequently increases the risk of psychiatric disorders and may exacerbate pre-existing problems. This study was designed to explore the risk factors of psychological symptoms among freshmen in China.</p><p><b>METHODS</b>A three-year follow-up study was designed in a sample of Chinese college freshmen. To set up the baseline interviews, subjects from 25 high schools in Beijing were interviewed during the first year in high school. Three years later, we followed up with the 1547 students from 15 of the previously-selected 25 high schools after they had entered universities. Association between potential risk factors and the occurrence of psychological symptoms measured by the Symptoms Check List-90 was evaluated in unconditional logistic regression models with Wald test.</p><p><b>RESULTS</b>Among the 1547 interviewed college freshmen in the study, 120 students (7.8%) manifested at least one psychological symptom. Personality dysfunction (OR = 3.655, 95% CI 1.967-6.793), parental rejection (OR = 2.619, 95% CI 1.544-4.442), age ≥ 20 (OR = 2.578, 95% CI 1.227-5.418), disfavored university (OR = 2.054, 95% CI 1.376-3.066), non-first-choice academic major (OR = 1.887, 95% CI 1.255-2.837) and no orientation (OR = 1.739, 95% CI 1.025-2.951) were determined to be the risk factors of psychological symptoms among the college freshmen in China.</p><p><b>CONCLUSIONS</b>Psychological symptoms of college freshmen are associated with personality traits, parental rearing behavior and study environment. Therefore, it is important to pay attention to changes in mental health as students enter or decide on colleges and increase education geared towards mental health issues for students in high school and universities in China.</p>

In order to control and prevent SARS, strict management was conducted in three universities which providing various social supports. Out of the 6280 students, 460 had SCL-90 positive symptoms with a rate of 7.3%. Risk factors of SCL-90 positive symptom were found as follows: major in arts (OR = 2.00), misconception on the control and prevention of SARS (OR = 1.91), considering measures non-effective (OR = 2.25), and do not believe that SARS can be under control (OR = 3.57). Protective factors of SCL-90 positive symptom would include as: being female (OR = 0.77), being graduate students (OR = 0.38), and being not much influenced on study and daily life during the period of strict management (OR = 0.54).</p><p><b>CONCLUSION</b>Psychosocial status of students was influenced by their knowledge and attitude on SARS. Various social supports might keep the university students to having a healthy psychosocial status.</p>
