项目摘要
PROJECT SUMMARY/ABSTRACT
Many leading causes of death have declined significantly over the past 100 years (e.g., tuberculosis,
pneumonia/influenza, gastritis);; however, the suicide rate is virtually identical to what it was 100 years
ago. Lack of progress in the prevention of suicide is due in large part to the limited understanding of
this problem. Suicidal thoughts and behaviors (STBs), like other behavior problems (e.g., alcohol use,
substance use, eating disorders), rarely occur in the research lab where they can be carefully probed
and cannot be ethically induced in the lab. As a result, experts lack a firm understanding of the
fundamental properties of STBs, and of how, why, and when they unfold in nature. The purpose of
this study is to address this enormous gap by using newly developed smartphone and wearable
biosensor technologies to conduct an intensive longitudinal study that will advance the understanding
and prediction of STBs and related behaviors. This study will monitor 600 people (300 adults and 300
adolescents) at elevated risk of STBs (i.e., those presenting to a psychiatric hospital with suicide
ideation and/or a recent suicide attempt) during a high risk time period (i.e., post-hospitalization). The
first aim of this study is to identify digital phenotypes of STBs using data collected both
actively/subjectively using repeated smartphone surveys and passively/objectively using continuous
data from smartphones (e.g., GPS, accelerometer, communications data) and wearable biosensors
(e.g., electrodermal activity, accelerometer). The second aim is to map the dynamic trajectories of
STBs over time. The third aim is to identify short-term predictors of STBs during the 6 months post-
hospital discharge. Ongoing research by the proposed team demonstrates the feasibility of: recruiting
and retaining the proposed samples, intensively monitoring them over time using digital devices, and
using analyses of these rich data streams to make discoveries about how STBs and related
behaviors unfold in nature. The data collected in this study will provide a rich data source that will be
used by our research team and collaborative researchers to advance the understanding, prediction,
and ultimate prevention of STBs and related outcomes.
项目摘要/摘要
在过去的100年中,许多主要的死亡原因大幅下降(例如结核病,
肺炎/流感,胃炎);但是,自杀率实际上与100年相同
关于预防自杀的缺乏,很大程度上是由于对
这个问题。自杀思想和行为(STB),与其他行为一样(例如,酒精使用,
物质使用,饮食失调),很少发生在研究实验室中,可以仔细探测它们
并且不能在实验室中符合道德诱导。结果,专家缺乏对
STB的基本属性以及它们在自然界中如何,原因和何时展开的基本属性。目的
这项研究是通过使用新开发的智能手机和可穿戴设备来解决这一巨大差距
生物传感器技术进行深入的纵向研究,以提高理解
和STB和相关行为的预测。这项研究将监视600人(300名成人和300人)
青少年)处于STB的风险较高(即,那些自杀的精神病医院
在高风险时期(即院后化)期间的构想和/或最近的自杀企图。这
这项研究的第一个目的是使用收集的数据鉴定STB的数字表型
积极/主观地使用重复的智能手机调查,并使用连续/客观地进行/客观
来自智能手机(例如GPS,加速度计,通信数据)和可穿戴生物传感器的数据
(例如,电肌活动,加速度计)。第二个目的是映射动态轨迹
随着时间的流逝。第三个目的是确定STB的短期预测因子 -
医院出院。拟议团队正在进行的研究表明:招聘的可行性
并保留提出的样品,使用数字设备随时间进行密切监视它们,然后
使用对这些丰富数据流的分析,以发现有关STB和相关方式的发现
行为本质上展现出来。本研究中收集的数据将提供丰富的数据源
我们的研究团队和合作研究人员使用,以提高理解,预测,
以及最终预防STB和相关结果。
