DESCRIPTION (provided by applicant): Older adults have higher rates of suicide than younger individuals in the U.S. (and most countries in the world) and the size of the older adult population will rise dramatically in the coming decades, making suicide in later life an issue of pressing public health concern. It is not known how to prevent suicide among older adults; empirical data indicating how to prevent suicide among this high-risk population are notably lacking. The Candidate's career development goal is to be a leading expert in the study of suicide and its prevention in older adults. Reaching that goal requires training in three domains of geriatric research (described below), as well as completion of a mentored research project that will produce substantive, foundational results (also described below). Primary care is a key site for late life suicide prevention: two-thirds or more of older adults who die by suicide are seen by primary-care physicians within a month of their deaths, and up to half within a week. Depressed older adults do not tend to seek specialty mental health treatment. For this reason, Training Objective 1 for this K23 proposal is to gain expertise interfacing with primary care as a site for both recruitment and implementation of innovative interventions with older adults at risk for suicide. It is also known that depression is a strong risk factor for late-life suicide, but te vast majority of depressed older adults do not die by suicide. Further, evidence is beginning to accumulate suggesting that targeting depression in older adults does not sufficiently lower suicide risk among older adults. For example, in the PROSPECT trial, a significant number of older adults remained suicidal at the end of the intervention. Thus, intervention studies targeting older adults at risk for suicide are needed; in particular, we need to understand how these interventions work to effectively implement and disseminate them. For this reason, Training Objective 2 is to gain expertise in the implementation of behavioral intervention protocols for older adults. Depressed older adults frequently present with cognitive impairment. Further, social functioning deficits are also associated with cognitive impairment. Thus, to properly characterize research samples and draw valid inferences from data, the candidate will need to know how to accurately assess cognitive decline. For this reason, Training Objective 3 is to gain knowledge of, and skills assessing, aging-related cognitive decline. The candidate's program of research will be informed by her training and experience as a clinical psychologist, in particular by theoretical and empirical evidence that she helped establish showing the central importance of social disconnectedness to suicide. With the long-term research goal of improving interventions for late-life suicide, the principal objective of the research study proposed here is to examine whether increasing social connectedness -- the degree to which older adults feel connected to, and as if they contribute to, valued relationships -- is a mechanism by which behavioral interventions reduce risk for suicide. To achieve this objective, the candidate requires pilot data demonstrating that a manualized (thus replicable) behavioral intervention does, in fact, increase connectedness while adjusting for correlates of connectedness-depression and cognitive functioning. Despite the likelihood of this association, the question has simply not been comprehensively addressed. This study will recruit n = 100 adults aged 60 years from primary care who endorse both disconnectedness (i.e., feeling lonely and/or like a burden on others) and clinically significant depression. Subjects will be randomly assigned to a behavioral intervention targeting disconnectedness (i.e., Interpersonal Psychotherapy; IPT) or care-as-usual (CAU). At baseline, 3-month, and 6-month assessments, subjects will report on social connectedness, cognitive decline, and depression. The project's Research Aims are: Aim 1: To examine whether a manualized intervention (IPT) can increase connectedness among older adults. Aim 2: To examine whether an intervention targeting social functioning (IPT) also reduces late-life suicide risk. Aim 3: To examine increases in connectedness as a mechanism whereby IPT decreases depression. The resulting findings of this K23 project on depression and death ideation (i.e., indicators of suicide risk) will function as the basis for a larger R01-funded study powered to examine suicide ideation and behavior as outcomes. These findings will be coupled with the candidate's substantial pilot data supporting the link between disconnectedness and both suicide ideation/behavior and depression. Subsequent to this award, the candidate will build on the skills acquired in this period of mentored career development to contribute to the development and refinement of approaches to suicide prevention in later life.

描述(申请人提供)：在美国(和世界上大多数国家)，老年人的自杀率比年轻人更高，未来几十年，老年人人口的规模将急剧上升，使晚年自杀成为一个紧迫的公共卫生问题。目前还不知道如何防止老年人自杀；值得注意的是，缺乏关于如何在这一高危人群中预防自杀的经验数据。候选人的职业发展目标是成为研究老年人自杀及其预防的领先专家。要实现这一目标，需要在老年学研究的三个领域进行培训(如下所述)，以及完成一项将产生实质性基础性成果的有指导的研究项目(也见下文所述)。初级保健是预防晚年自杀的关键场所：三分之二或更多自杀的老年人在死亡后一个月内被初级保健医生看过，最多在一周内看过一半。抑郁的老年人不倾向于寻求专门的心理健康治疗。出于这个原因，这项K23提案的培训目标1是获得与初级保健对接的专业知识，作为招募和实施创新干预措施的地点，以应对有自杀风险的老年人。众所周知，抑郁症是晚年自杀的一个强烈风险因素，但绝大多数抑郁的老年人并不是自杀而死。此外，越来越多的证据表明，针对老年人的抑郁症并不能充分降低老年人的自杀风险。例如，在PROSPESS试验中，相当数量的老年人在干预结束时仍有自杀倾向。因此，干预研究的目标是 需要有自杀风险的老年人；我们尤其需要了解这些干预措施如何有效地实施和传播这些干预措施。为此，培训目标2是在为老年人实施行为干预方案方面获得专业知识。抑郁的老年人经常出现认知障碍。此外，社会功能缺陷也与认知障碍有关。因此，为了恰当地描述研究样本并从数据中得出有效的推论，候选人需要知道如何准确地评估认知能力下降。为此，培训目标3是获得与年龄相关的认知衰退的知识和技能评估。候选人的研究计划将从她作为临床心理学家的培训和经验中获得启发，特别是她帮助建立的表明社会脱节对自杀的核心重要性的理论和经验证据。以改善晚年自杀干预措施为长期研究目标，本研究的主要目的是 为了检验增加的社会联系--老年人感觉与有价值的关系的联系程度，似乎他们对有价值的关系做出贡献--是否是行为干预降低自杀风险的一种机制。为了实现这一目标，候选人需要试点数据，证明人工(因此可复制的)行为干预实际上确实增加了连接性，同时调整了连接性的相关性--抑郁和认知功能。尽管存在这种联系，但这个问题根本没有得到全面解决。这项研究将招募n=100名来自初级保健的60岁成年人，他们既有脱节的感觉(即感觉孤独和/或像是他人的负担)，也有临床上显著的抑郁症。受试者将被随机分配到针对脱节(即人际心理治疗；IPT)或照常护理(CAU)的行为干预。在基线、3个月和6个月的评估中，受试者将报告社交联系、认知能力下降和抑郁。该项目的研究目标是：目标1：检查人工干预(IPT)是否可以增加老年人之间的联系。目的2：研究针对社会功能(IPT)的干预是否也能降低晚年自杀风险。目的3：研究连接增加作为IPT减轻抑郁的一种机制。这项关于抑郁和死亡意念(即自杀风险的指标)的K23项目的结果将作为R01资助的一项更大规模研究的基础，该研究旨在检查自杀意念和行为作为结果。这些发现将与候选人大量的飞行员数据相结合，支持断开联系与自杀想法/行为和抑郁之间的联系。在此奖项之后，候选人将在这段接受指导的职业发展阶段获得的技能基础上，为以后生活中预防自杀的方法的发展和完善做出贡献。
