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, = 38.5 years, = 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.
本研究采用横断面设计，评估了新冠大流行应激、睡眠障碍和物质使用在一个全国性样本中的关联，该样本由 143 名成年人（57.3%为男性，年龄 = 38.5 岁，= 11.28）组成，他们在亚马逊的 MTurk 平台上一次性接受调查。我们假设，新冠大流行相关应激通过睡眠障碍严重程度与物质使用结果（即每日使用的物质种类数量、每次饮酒的酒精量、物质使用应对动机；但不包括物质使用增强动机）存在间接关系。正如预期的那样，结果表明，检验间接效应的模型在每日使用的物质种类数量和物质使用应对动机方面具有统计学意义。然而，没有证据表明睡眠障碍解释了新冠大流行相关应激与每次饮酒的酒精量或物质使用增强动机之间的关系。这些发现强调了睡眠障碍在努力更好地理解新冠大流行相关应激如何与某些类型的物质使用行为相关联方面的重要性。
