This competing continuation proposal examines changes in suicidal behaviors and related risk and protective factors. Suicide is a major cause of death among youth aged 15-24 years. Suicide rates increase sharply from 20-24 years. Potential high school dropouts are known to be at higher risk than average for suicide and suicidal behaviors. Research indicates they enter young adulthood with greater risk and fewer protective factors. What is unknown is the impact of adolescent suicidal behaviors on young adult outcomes. This proposal describes a 4-wave, longitudinal study of high-risk youth across young adulthood (18-23 years). Study aims are to 1) test the temporal stability of a measurement model of suicide potential in adolescents vs. young adults; 2) study the longitudinal effects of adolescent risk and protective factors on the health outcomes of emotional distress, drug involvement, functional status, and suicidal behaviors; and to 3) examine patterns of change in suicide risk and related risk and protective factors across young adulthood, identifying predictors of these patterns of change. Subjects will be 1,150 young adults (18-23 years), identified as potential high school dropouts in the parent grant, and comprehensively assessed for suicide potential when 15-18 years old. The sample is approximately 48 percent female and 60 percent minority. Subjects will be surveyed annually 4 times and will participate in a comprehensive, suicide-risk assessment interview the final year. Young adult outcome variables include suicidal behaviors (thoughts/threats/attempts) and the related risk factors of emotional distress, drug involvement and functional status. Mediators include personal and social protective factors (coping/support). Three analytic approaches will be used: 1) confirmatory factor analyses to test factor stability of outcome construct; 2) structural equation modeling to test hypothesized relationships among adolescent antecedents and young adult outcomes; and 3) latent growth curve modeling (LGM) to determine patterns and predictors of change in suicidal behaviors across young adulthood.

该竞争性延续建议检查自杀的变化 行为和相关风险和保护因素。自杀是 15-24岁的青年死亡。自杀率从20-24急剧增加 年。潜在的高中辍学者的风险高于 自杀和自杀行为的平均水平。研究表明他们进入年轻 成年，风险更大，保护因素更少。未知是 青少年自杀行为对年轻成人结果的影响。这 提案描述了一项对年轻人的高风险青年的4波纵向研究 成年（18-23岁）。研究目的是1）测试a的时间稳定性 青少年与年轻人的自杀潜力的测量模型； 2） 研究青少年风险和保护因素对 情绪困扰，药物参与，功能状况和 自杀行为； 3）检查自杀风险变化的模式和 整个成年期相关的风险和保护因素，确定 这些变化模式的预测指标。受试者将是1,150名年轻人 （18-23岁），被认为是父母潜在的高中辍学 赠款，并在15-18岁时全面评估自杀潜力。 样本约为女性48％，少数60％。主题 将每年进行4次调查，并将参加全面的， 自杀风险评估访谈的最后一年。年轻成人结果变量 包括自杀行为（思想/威胁/尝试）和相关风险 情绪困扰，药物参与和功能状况的因素。 调解人包括个人和社会保护因素（应对/支持）。 将使用三种分析方法：1）确认性因素分析以测试 结果构建的因素稳定性； 2）测试的结构方程建模 青少年前因与年轻成人之间的假设关系 结果； 3）潜在生长曲线建模（LGM）确定模式和 整个成年期自杀行为变化的预测因素。
