Examining the influence of substance use on mental health rating during COVID-19: A Canadian perspective

Introduction

Substance use and mental health symptoms (e.g., depression and anxiety) have increased during the COVID-19 pandemic, partly due to implementation of physical distancing measures aimed at containing the spread of the SARS-CoV-2 virus. However, there is limited pandemic-specific research that has examined the relationship between substance use and mental health with other correlates of well-being, including life satisfaction and social confidants.

Methods

In the current study, we used ordered logistic regression analyses to examine whether a greater frequency of substance use (e.g., alcohol, cannabis, and opioids) during the pandemic predicted poorer ratings of self-reported mental health in a large sample of Canadians aged 15 to 64 years. We further considered whether life satisfaction and number of social confidants interacted with substance use to influence mental health, and stratified the models by sex and personal feelings of shame surrounding the use of substances (i.e., high and low shame).

Results

Findings indicated that frequency of substance use was significantly associated with increased odds of reporting poorer mental health for males and females exhibiting both low and high shame. In females reporting low shame, we found that as frequency of cannabis use increased, life satisfaction has a much greater positive association with mental health. Whereas, in females disclosing high shame, maintaining social relations was particularly important to benefit the mental health of current users of opioids, relative to past and non-users. No such interaction was found in males.

Discussion

Overall, the findings of the current study showed the negative mental health consequences of substance use during COVID-19 in a large Canadian sample, and most importantly revealed a critical sex difference in the way in which social determinants interact with substance use to influence mental health.

The relationship of COVID-19 traumatic stress, cumulative trauma, and race to posttraumatic stress disorder symptoms

The purpose of this study was to test if coronavirus disease 2019 (COVID-19) traumatic stress predicts posttraumatic stress disorder (PTSD) symptoms after cumulative trauma and whether there is a three-way interaction between COVID-19 traumatic stress, cumulative trauma, and race in the prediction of PTSD. Using a cross-sectional design, a diverse sample of 745 participants completed measures of cumulative trauma, COVID-19 traumatic stress, and PTSD. COVID-19 traumatic stress accounted for a significant amount of the variance in PTSD above and beyond cumulative trauma. A significant interaction effect was found, indicating that the effect of COVID-19 traumatic stress in predicting PTSD varied as a function of cumulative trauma and that the effects of that interaction were different for Asians and Whites. There were generally comparable associations between COVID-19 traumatic stress and PTSD at low and high levels of cumulative trauma across most racial groups. However, for Asians, higher levels of cumulative trauma did not worsen the PTSD outcome as a function of COVID Traumatic Stress but did at low levels of cumulative trauma.
