摘要
抑郁症是常见的,昂贵的,是残疾的主要原因。行为和经验的评估
抑郁症倾向于依赖自我报告和基于访谈的方法。环境瞬时评估插件
这是一个非常重要的问题,因为它有助于将评估纳入人们的生活,但仍然需要被评估者的积极参与。我们建议发展和
验证基于移动的电话的个人感测系统以检测依赖于传感器的抑郁和相关行为
这些数据是连续收集的,不引人注目。因为人们倾向于随身携带手机,所以移动的
手机是一个理想的传感平台,因为它可以在个人生活的背景下连续收集数据,
用户的持续努力。这样的系统已经被用来检测简单的行为,比如活动

英文摘要
Abstract
Depression is common, costly, and a leading cause of disability. Assessment of behavior and experience related to
depression has tended to rely on self-report and interview-based methods. Environmental momentary assessment inserts
assessment into people's lives, but still requires active engagement by those being evaluated. We propose to develop and
validate a mobile phone-based personal sensing system to detect depression and related behaviors that relies on sensor
data that are collected continuously and unobtrusively. Because people tend to keep their phones with them, the mobile
phone is an ideal sensing platform, as it can continuously collect data in the context of the individual's life with no
ongoing effort on the part of the user. Such systems are already being used to detect simple behaviors, such as activity
recognition and sleep quantification, which are more proximal to the sensor data. Aim 1 will develop markers for a broad
range of behavioral targets related to symptoms of major depressive episode (MDE; anhedonia, negative mood, sleep
disruption, psychomotor activity, fatigue, and diminished concentration) and related domains (e.g. social functioning,
stress, motivation) across a representative sample of participants. Aim 2 will combine all behavioral targets using machine
learning to 1) estimate MDE and symptom severity cross-sectionally, 2) identify transition from non-depressed to
depressed states, and depressed to non-depressed states, and 3) predict MDE and symptom severity 4 and 8 weeks out.
Aim 3 will seek to understand the complex relationships among behavioral targets and depression. We will accomplish
this by enrolling 1200 representative participants, in six 4-month waves of data collection. Each participant will
download software that collects a wide variety of sensor data (GPS, accelerometry, light, Bluetooth, phone usage, etc.)
and an app that collects ecological momentary assessments (EMA). Following each wave we will develop algorithms for
a subset of behavioral targets and features (a definition of raw sensor data that incorporates meaning, like translating GPS
data into “home”). Each algorithm will then be validated in the subsequent wave. After 5 waves (1000 participants), the
set of all markers of behavioral targets and features will be combined using machine learning to detect and predict
depression. This hierarchical approach extracts information from data at multiple levels, which ultimately is far more
likely to succeed than relying solely on raw sensor data. The final wave will serve to replicate and validate the entire
depression prediction model. This sensing platform is scientifically significant, as it will provide a fundamentally new tool
for obtaining continuous, objective markers of behavior that are relevant to depression, as well as many other psychiatric
and medical disorders. This project has the potential develop new understandings into the etiology of depression. It is
clinically significant, as it will allow for continuous, effortless assessment of populations at risk for depression and
ongoing evaluation during treatment.
