Self-rated mental health, sense of community, life satisfaction, and perceived change in mental health among adults during the second and third waves of the COVID-19 pandemic in Canada

Based on results from the 2020 COVID-19 and Mental Health Survey (CMHS), positive mental health among adults in Canada was lower during the second wave of the pandemic (fall 2020) than in 2019. Using the winter and spring 2021 CMHS data analyzed in this study, we were able to find that average life satisfaction and the prevalence of high self-rated mental health, strong sense of community, and perceived stable or better mental health were even lower during the third wave of the pandemic than during the second wave , both in the overall adult population and among most sociodemographic groups.
