To study the prevalence of mental disorders among the Chinese youths aged 15 - 34 years, in rural areas and to identify risk factors related to suicide.
A consecutive sampling strategy was used for suicidal cases in 16 randomly selected counties in Hunan, Liaoning, and Shandong provinces. Between 2005 and 2008, a total of 392 suicide cases were recruited with 416 community controls at the same age range, selected from the same areas one family member together with one close friend of each suicidal case were interviewed, using the psychological autopsy (PA) method. The same method with structured instruments was performed on the two informants for each control in the same community. SCID was used for the diagnosis of mental disease.
48.0% of the suicides were diagnosed as having at least one mental disorder episode, in comparison with only 3.8% among the controls. It was found that mental disorder was the most important risk factor for the Chinese young suicide cases in the rural areas.
As seen in the Western countries, mental disorder had also been the number one correlate on suicidal cases in China, with the difference as other social and psychological factors might have played relatively more important roles in China.
研究中国农村地区15 - 34岁青少年精神障碍的患病率，并确定与自杀相关的危险因素。
采用连续抽样策略，对湖南、辽宁和山东16个随机抽取的县的自杀病例进行研究。在2005年至2008年期间，共招募了392例自杀病例，并选取了416名相同年龄范围的社区对照，这些对照来自同一地区，对每个自杀病例的一名家庭成员和一名亲密朋友进行访谈，采用心理解剖（PA）方法。对同一社区的每个对照的两名 informant 使用相同的结构化工具进行相同方法的调查。使用SCID诊断精神疾病。
48.0%的自杀者被诊断为至少有一次精神障碍发作，而对照组中这一比例仅为3.8%。研究发现，精神障碍是中国农村地区年轻自杀病例最重要的危险因素。
与西方国家一样，精神障碍也是中国自杀病例的首要相关因素，不同的是其他社会和心理因素在中国可能发挥了相对更重要的作用。
