Objective: There have been significant concerns regarding the mental health impact of coronavirus disease 2019 , due to isolation, anxiety around the pandemic, and increased conflict in the home.The purpose of this study was to examine the rates of mental health problems and substance use, and to assess which COVID-19 related stressors were predictors of mental health and substance use in a large Canadian sample of adolescents, with comparisons across genders.Method: Participants (N = 809, Mage = 15.67,SD = 1.37) identified as a girl (56.2%), boy (38.7%), or trans/non-binary individual (TNBI; 5.1%) and were recruited via social media to complete an online survey.Results: A high proportion of adolescents met clinical cut-offs for depression (51%), anxiety (39%), and post-traumatic stress disorder (45%).Other mental health problems ranged from 9%-20%.Adolescents were mainly concerned with the health of family members and vulnerable populations, as well as the increased family stress at home during COVID-19.Rates of substance use were higher than expected, with over 50% of youth engaging in some form of substance use in the past 90 days, and almost 20% engaging in substance use at least once a week.TNBI and girls reported higher rates of mental health problems compared to boys.Family stress due to confinement and violence at home predicted higher rates of mental health, but not substance use problems.Conclusions: Increased rates of mental health problems and substance use necessitate targeted supports that encourage positive coping amidst the additional stresses of COVID-19.
