Background： 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. Methods： 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.

Results： Data of 2,526,145 respondents were analyzed. The disability prevalence rate attributed to mental disorders in China was 6.3%0, 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. Conclusions： 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.

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. Methods： 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. Results： 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.
