背景资料：一般人群的调查数据，提出了终身患病率的自杀企图，以及转换概率开始的想法，计划之间的想法，并尝试之间的想法，无论有或没有计划。这些转变的风险因素也studyed.Methods：数据是从第二部分的全国科摩罗调查，一个具有全国代表性的调查进行了1990年至1992年的样本中的5877名受访者，年龄在15至54岁，研究患病率和相关的DSM-III-R疾病。使用寿命表分析估计过渡。使用生存analysis.Results：的受访者，13.5%的报告一生的想法，3.9%的计划，和4.6%的尝试的风险因素进行了检查。从构思到计划的过渡的累积概率为34%，从计划到尝试的累积概率为72%，从构思到计划外尝试的累积概率为26%。大约90%的计划外和60%的计划内的首次尝试发生在构思开始的1年内。所有重要的危险因素（女性，以前结婚，年龄小于25岁，在最近的队列，教育程度低，并有1个或多个DSM-III-R的疾病在调查中评估）更密切相关的构思比进展从构思到计划或attempty.Conclusions：预防工作应集中在计划的尝试，因为快速发病和不可预测性的计划外的尝试。需要对计划外尝试的决定因素进行更多的研究。
Background: General population survey data are presented on the lifetime prevalence of suicide attempts as well as transition probabilities to onset of ideation, plans among ideators, and attempts among ideators either with or without a plan. Risk factors for these transitions are also studied.Methods: Data are from part II of the National Comorbidity Survey, a nationally representative survey carried out from 1990 to 1992 in a sample of 5877 respondents aged 15 to 54 years to study prevalences and correlates of DSM-III-R disorders. Transitions are estimated using life-table analysis. Risk factors are examined using survival analysis.Results: Of the respondents, 13.5% reported lifetime ideation, 3.9% a plan, and 4.6% an attempt. Cumulative probabilities were 34% for the transition from ideation to a plan, 72% from a plan to an attempt, and 26% from ideation to an unplanned attempt. About 90% of unplanned and 60% of planned first attempts occurred within 1 year of the onset of ideation. All significant risk factors (female, previously married, age less than 25 years, in a recent cohort, poorly educated, and having 1 or more of the DSM-III-R disorders assessed in the survey) were more strongly related to ideation than to progression from ideation to a plan or an attempt.Conclusions: Prevention efforts should focus on planned attempts because of the rapid onset and unpredictability of unplanned attempts. More research is needed on the determinants of unplanned attempts.
