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.
项目总结/摘要
在过去的100年里,许多主要的死亡原因已经显著下降(例如, 肺结核,
肺炎/流感,胃炎);然而,自杀率几乎与100年前相同
在预防自杀方面缺乏进展在很大程度上是由于对自杀的认识有限。
这个问题。自杀的想法和行为(STBs),像其他行为问题(例如, 酗酒,
物质使用,饮食失调),很少发生在研究实验室,在那里他们可以仔细探讨
在实验室中无法进行伦理诱导。因此,专家们对
的基本属性,以及如何,为什么,以及何时在自然界中展开。
本研究旨在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,将促进了解
本研究将监测600人(300名成年人和300名
青少年)在STBs的高风险(即, 那些因自杀而被送往精神病院的人
意念和/或最近的自杀企图)(即, 住院治疗后)。
本研究的第一个目的是使用收集的数据来识别STB的数字表型,
主动/主观地使用重复的智能手机调查,被动/客观地使用连续的
来自智能手机的数据(例如, GPS、加速度计、通信数据)和可穿戴生物传感器
(e.g., 第二个目的是绘制皮肤电活动的动态轨迹,
第三个目标是在治疗后的6个月内确定短期的STBs预测因子。
出院。拟议的团队正在进行的研究证明了以下可行性:
并保留拟议的样本,使用数字设备随着时间的推移对其进行集中监测,
通过分析这些丰富的数据流,
行为在自然界中展开。本研究收集的数据将提供丰富的数据源,
由我们的研究团队和合作研究人员使用,以促进理解,预测
和最终预防性传播疾病及相关结果。
