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

Covid-19大流行是一场重大的全球和国家卫生紧急事件，尽管没有必要指出这一点，但有些地方还不相信它，这使得紧急情况更加可怕。在美国各地，Covid-19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。Covid-19大流行还与先前存在和正在发生的大流行相冲突：物质使用障碍（SUDs）。患有sud的人特别容易受到Covid-19的健康、社会和经济影响，并且随着Covid-19的经济和心理压力，sud患者的人数可能会增加。

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).
