COVID-19 & Mental Health Study
The COVID-19 pandemic has had a massive societal impact, likened to a disaster. Public health directives for self-isolation and physical distancing (COVID-19 Emergency Measures; EM) have led to the closure of non-essential services, including schools and recreational facilities. Existing literature has shown that disaster events and quarantine measures are known to cause psychological trauma, severe anxiety, irritability, and behavior changes. However, little is known about their impact on children particularly among the large proportion (1 in 5) of children in Canada with pre-existing mental health disorders, who are expected to be more vulnerable. With parents taking on unfamiliar role, such as supervising a child’s education, and children no longer having familiar routines, the psychological impact is expected to be high.
Four leading research teams in child mental health: SickKids Child and Youth Psychiatry Outpatient Program, the Province of Ontario Neurodevelopmental (POND) Network, The Applied Research Group for Kids (TARGet Kids!), and Spit for Science, joined forces to improve our understanding of the mental health and wellbeing among Canadian children, parents, and families during the COVID-19 pandemic. The study explores the impact of COVID-19 emergency measures on child and family mental health, well-being, and functioning. This includes understanding how children and their parents felt as a result of the COVID-19 emergency measures, in addition to the impact on their relationships (i.e., with friends and extended family members) and daily activities (e.g., physical activity [1], eating habits, screen time [2], and sleep). The team has continued to examine the impact of the emergency public health measures across multiple waves of the pandemic, including periods of repeated closures and societal re-opening. The pandemic-related disruption to education and children’s school experiences are also closely examined. This includes how children and youth think and feel about school and the critical role of extracurriculars, sports, and social learning activities as supports for child and youth mental health.
Beyond identifying severity of mental health among children, youth, and families during the pandemic, this study is helping to identify important points of intervention. This research is ongoing and we are continuing to investigate how best to support the mental health of young Canadians and their families. We are actively working with community partners in both the public health and education systems in an effort to promote resilience for future challenges that children and youth may face beyond the pandemic.
The COVID-19 and Mental Health Research Team has a strong commitment to the development of Early Career Investigators, as well as undergraduate and graduate-level trainees. Currently, 6 major research papers from the COVID-19 and Kids’ Mental Health Study have been led by trainees [3,4,5,6,7,8]. These individuals come from schools in medicine, psychiatry, psychology, education, and public health. We also provide opportunities for undergraduate students through an annual summer internship program offered by the University of Toronto and the Hospital for Sick Children.
