"The Walls Had Been Built": A Qualitative Study of Canadian Adolescent Perspectives on Mental Health During the COVID-19 Pandemic.

Public health measures (PHMs) implemented during the COVID-19 pandemic introduced sudden changes to adolescents' everyday routines and required adolescents to repeatedly adapt their routines at a critical developmental stage. While meant to protect physical health, the PHMs destabilized mental health. Using a youth-engaged approach and interpretive description, this study explored adolescents' perspectives on their mental health in relation to the COVID-19 pandemic-related PHMs in Canada from March 2020 to the time of data collection in March 2022. Four Youth Research Collaborators contributed an adolescent lens to informing study activities, and a total of 33 high-school aged adolescents ages 14 to 19 completed individual interviews. Findings suggest an overarching concept of a "timeline" through which adolescents described their experiences. Most adolescents described their mental health as worsening during the initial lockdown, although some adolescents experienced positive mental health outcomes. Several adolescents felt their mental health had not recovered after the PHMs were fully lifted. This study contributes young Canadians' unique voices to the literature on the pandemic-related PHMs and adolescent mental health. It is essential that the impacts of the pandemic on adolescent mental health continue to be a focus of research and programming to better understand and address its ongoing effects.
