DESCRIPTION (provided by applicant): Suicide remains a leading cause of death among young people--each year 1 in 5 teenagers considers suicide and approximately one million attempt suicide. These rates continue to escalate into young adulthood. Youth suicide-risk behavior is a major public health problem deserving immediate attention to critical intervention factors that promote short-term and maintain long-term behavioral change. This proposal examines psychosocial processes associated long-term behavioral change following participation in an indicated suicide prevention program, and responds specifically to RFA OB-03-003. The proposal takes advantage of a nearly completed prevention trial, Promoting CARE funded by the National Institute for Nursing Research. The program has demonstrated short-term outcome effects for suicide-vulnerable high school youth. The Promoting CARE study will provide a sample of approximately 550 vulnerable youth, randomly assigned to 1 of 3 experimental conditions, and compared to intervention "as usual." The study has been rigorously implemented, with extensive measures collected at baseline, post-intervention, 9 and 15 months post-baseline, and, for half the sample, at 30 months. With an extended follow-up to 48 months, we will 1) test for long-term intervention effects; 2) test the theoretic model, examining for mediational intervention effects on both short- and long-term behavioral outcomes; and 3) identify trajectories of change across time. Advanced statistical procedures (latent growth models, SEM) will be used to examine behavioral change and to test hypothesized mediating intervention effects. The influence of intervention processes and life course factors on patterns of change will be examined using multi-method approaches and exploratory analytic strategies. The proposed study is innovative and significant; it has implications for theory testing and prevention science. This research should markedly increase our understanding of ways in which youth and family-focused preventive interventions for suicide-vulnerable youth work to curb depression, anger and suicide-risk behaviors.

描述（由申请人提供）：自杀仍然是年轻人中的主要死亡原因 - 每5年级中的1年级都认为自杀和大约一百万次自杀。这些比率继续升级为年轻成年。青年自杀危行为是一个主要的公共卫生问题，值得立即关注关键干预因素，这些因素促进短期并维持长期行为改变。该提案研究了参与指定的自杀预防计划后与长期行为改变相关的社会心理过程，并专门响应RFA OB-03-003。该提案利用了几乎完成的预防试验，促进了国家护理研究所资助的护理。该计划证明了对可自杀的高中青年的短期结果影响。促进护理研究将提供大约550名弱势青年的样本，随机分配给3个实验条件中的1个，并与“照常”进行干预。这项研究已被严格实施，基线后，干预后，基线9和15个月采取了广泛的措施，在30个月的样本中，一半的样本中采取了措施。 随着时间的延长至48个月，我们将1）测试长期干预效果； 2）测试理论模型，检查中介干预对短期和长期行为结果的影响； 3）确定跨时间变化的轨迹。高级统计程序（潜在生长模型，SEM）将用于检查行为变化并测试假设的中介干预效果。干预过程和生活课程因素对变化模式的影响将使用多方法方法和探索性分析策略进行检查。拟议的研究具有创新性和意义。它对理论测试和预防科学具有影响。这项研究应该显着提高我们对青年和家庭以自杀式预防性干预措施的方式的理解，以遏制抑郁症，愤怒和自杀风险行为。
