COVID-related stress and substance use: examining the role of sleep disturbance

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.
