Changes in Substance Use Following COVID-19: Harnessing Digital Phenotyping

新型冠状病毒肺炎（COVID-19，即2019冠状病毒病）大流行是一个重大的全球和国家卫生紧急情况，尽管没有必要指出这一点，但有些地方还不相信这一点，这使得紧急情况更加可怕。在美国各地，新冠肺炎对有色人种社区、低收入人群和缺乏稳定住房的人群的影响尤为严重。新型冠状病毒肺炎（COVID-19，即2019冠状病毒病）大流行还与一种先前存在且正在持续的大流行相冲突：物质使用障碍（SUD）。SUD患者特别容易受到Covid-19的健康、社会和经济影响，SUD患者的数量可能会随着Covid-19的经济和心理压力而增加。 本项目的目的是：1）在研究开始时，在有和没有SUD的人群中，研究COVID-19大流行对药物使用、药物相关行为和药物使用后果的影响; 2）在有或发生SUD的人群中，研究COVID-19大流行与获得/坚持治疗之间的双向影响;以及3）改进检测以下日常生活行为标记的方法：（a）运动模式，（B）社会互动、支持和疏远，（c）物质使用，（d）复原力和幸福感，以及（e）心理问题（包括流行病特有的问题）。

The Covid-19 pandemic is a major global and national health emergencyand although it should be unnecessary to point that out, there are places where it is not yet believed, making the emergency all the more dire. Across the US, Covid-19 is disproportionately impacting communities of color, people with lower incomes, and people who lack stable housing. The Covid-19 pandemic is also colliding with a preexisting and ongoing pandemic: substance use disorders (SUDs). People with SUDs are particularly vulnerable to the health, social, and economic impacts of Covid-19and the number of people with SUDs is likely to increase with the economic and psychological stress of Covid-19. The aims of this project are to 1) investigate the effects of the Covid-19 pandemic on drug use, drug-related behaviors, and consequences of drug use, in people with and without SUDs at the start of the study; 2) investigate bidirectional effects between the Covid-19 pandemic and access/adherence to treatment, in people who have or develop SUDs; and 3) improve methodology for detection of daily-life behavioral markers of (a) movement patterns, (b) social interactions, support, and distancing, (c) substance use, (d) resilience and wellbeing, and (e) psychological problems (including pandemic-specific problems).
