DESCRIPTION (provided by applicant): Available data indicate that unplanned versus planned acts have different correlates and may require different prevention strategies. However, data are limited by small samples, uncontrolled data, inadequate measures of planning, and samples of attempted suicide (as opposed to suicide). The proposed study overcomes these limitations in a rigorous, controlled investigation. Aim 1 tests the hypotheses that unplanned (versus planned) acts of suicidal behavior are associated with greater acute stress, are more likely to be preceded by a severe life event, but are associated with lower depressive symptoms and lower chronic stress. Aim 2 tests the hypotheses that unplanned acts are associated with younger age and rural (versus urban) residency. In Aim 3, a multivariate model of attempted suicide will be constructed, and correlates of planned versus unplanned suicide attempts will be identified based on the model. To address these aims, in this secondary analysis grant, two large, case-control datasets will be analyzed: 1) 519 suicide decedents and 536 nonsuicide injury death controls, and 2) 312 suicide attempters and 312 living community controls. All data were gathered in China (Phillips, PI). Data on suicides and their injury death controls were gathered to reflect the sociodemography of the general population. Suicide attempters were sampled from a general hospital, and controls were community members matched for gender, age, and location. Data were gathered using rigorous methods. The data sets will be analyzed separately although with the same basic approach - unordered multinomial logistic regression. The study represents a rare opportunity to examine the heterogeneity in attempted suicide and particularly in suicide, with implications for prevention in China where the suicide rate is very high, but also in the U.S. as a continuum of suicidal planning, as well as numerous risk factors, transcend cultures.

描述（由申请人提供）：现有数据表明，计划外行为与计划内行为有不同的相关性，可能需要不同的预防战略。然而，数据受到样本量小、数据不受控制、计划措施不充分以及自杀未遂（与自杀相对）样本的限制。拟议的研究在严格的对照研究中克服了这些局限性。目的1测试的假设，即计划外（与计划）的自杀行为与更大的急性压力，更有可能是由一个严重的生活事件之前，但与较低的抑郁症状和较低的慢性压力。目标2检验以下假设：计划外行为与年龄较小和居住在农村（相对于城市）有关。在目标3中，将构建自杀未遂的多变量模型，并根据该模型确定计划与非计划自杀未遂的相关性。为了实现这些目标，在二次分析中，将分析两个大型病例对照数据集：1）519例自杀死亡者和536例非自杀伤害死亡对照，2）312例自杀死亡者和312例生活社区对照。所有数据均在中国收集（菲利普斯，PI）。收集自杀及其伤害死亡控制的数据，以反映一般人群的社会人口学。自杀未遂者是从一家综合医院抽样的，对照组是性别、年龄和地点相匹配的社区成员。采用严格的方法收集数据。将单独分析数据集，但采用相同的基本方法-无序多项逻辑回归。这项研究提供了一个难得的机会来研究自杀未遂的异质性，特别是自杀，这对自杀率非常高的中国的预防有意义，但在美国，自杀计划的连续性以及众多的风险因素，超越了文化。
