ABSTRACT

The current investigation employed a cross-sectional design to evaluate the associations of COVID-19 stress, sleep disturbance, and substance use among a national sample of 143 adults (57.3% male, M_age = 38.5 years, SD = 11.28), surveyed at a single time-point using Amazon’s MTurk platform. We hypothesized that COVID-19-related stress would be indirectly related to substance use outcomes (i.e. number of substance classes used daily, number of alcoholic drinks per occasion, substance use coping motives; but not substance use enhancement motives) through sleep disturbance severity. As expected, results indicated that the models examining indirect effects were statistically significant for number of substance classes used daily and substance use coping motives. However, there was no evidence that sleep disturbance explained the relation between COVID-19-related stress and number of alcoholic drinks per occasion or substance use enhancement motives. These findings underscore the importance of sleep disturbance in efforts to better understand how COVID-19-related stress is associated with certain types of substance use behavior.

摘要

目前的调查采用横断面设计来评估 COVID-19 压力、睡眠障碍和物质使用在全国 143 名成年人样本中的关联（57.3% 男性，M_年龄 = 38.5 岁，SD = 11.28），使用亚马逊的 MTurk 平台在单个时间点进行调查。我们假设与 COVID-19 相关的压力将通过睡眠障碍的严重程度与物质使用结果（即每天使用的物质类别数量、每次饮酒的数量、物质使用应对动机；但与物质使用增强动机）间接相关。正如预期的那样，结果表明，检验间接影响的模型对于每天使用的物质类别数量和物质使用应对动机具有统计学意义。然而，没有证据表明睡眠障碍可以解释 COVID-19 相关压力与每次饮酒次数或物质使用增强动机之间的关系。
