Increasing evidence has shown that the Covid-19 outbreak has impacted adolescents’ mental health. Utilising a mixed-method design, the current study examined a total of 518 adolescent perspectives (60% female), in Scotland, on what has and could help their mental health in the context of Covid-19. A reflexive thematic analysis revealed three themes in relation to what has helped adolescents’ mental health since the Covid-19 outbreak. These related to findings about the value of: (1) engaging in recreational activities, (2) engaging with friends, and (3) the disruption to schooling. The remaining four themes related to what could have helped adolescents mental health and wellbeing since the Covid-19 outbreak. These focussed on (1) better support: in relation to mental health; school work; and communication, (2) contact with friends, and (3) more opportunities for recreational activities. Males were more likely to report recreational activities had helped and less likely to report better support could have helped. Adolescents who reached clinical threshold for depression and anxiety and those with elevated PTSD-like symptoms about Covid-19 were more likely to state more support could have helped, and adolescents who reached clinical threshold for depression were less likely to report that friends could have helped their mental health. The findings may inform mental health policy and interventions in the recovery from the Covid-19 pandemic.

Increasing evidence has shown that the Covid-19 outbreak, and subsequent school closures and exam cancellations that followed, has impacted adolescent mental health. The current cross-sectional study examined rates of depression, anxiety and Post Traumatic Stress Disorder (PTSD)-like symptoms about Covid-19 in adolescents and whether current or past mental health support, additional support in school, keyworker status, poorer household relationships since the outbreak of Covid-19 or reduced physical activity were associated with elevated levels of depression, anxiety or PTSD-like symptoms. Lastly, it examined perceived changes in mental health due to the Covid-19 pandemic, school closures and the cancellation of exams. A total of 899 adolescents (14–18 years) took part in the ’in isolation instead of in school’ (INISS) project. Findings indicated that older adolescents, females, those who currently or previously received mental health support or additional support in school and adolescents who reported poorer relationships at home since Covid-19 were more likely to meet clinical threshold levels for their mental health. Adolescents highlighted worsening of their mental health due to Covid-19 and school closures with mixed positive and negative impact of exam cancellations. Adolescents experiencing clinical threshold levels of depression and anxiety uniquely reported worsening of their mental health since the Covid-19 pandemic, school closures and exam cancellations. Understanding the rates, perceptions and factors associated with increases in depression, anxiety and PTSD-like symptoms in adolescents during the Covid-19 pandemic will inform national policy in supporting adolescent mental health and recovery from the Covid-19 pandemic.
