Schools are central places for adolescent social lives, which is a major factor greatly affecting adolescent mental health; school climate (i.e. quality of the school social environments) can be a proximal social determinant for adolescent mental health. Supportive school environments may serve as a protective factor during crises like COVID-19, which disrupt social lives and worsen adolescent mental health. This is the first study examining whether the pandemic effects differed based on the levels of school climate on depressive symptoms (DS) and psychotic experiences (PEs) among adolescents.

School climate (score range: 0–28), DS (0–26), and PEs (0–5) were self-reported in a population-based cohort (Tokyo Teen Cohort; N = 3171) at four timepoints (10y, 12y, 14y, and 16y) before and during COVID-19. COVID-19 occurred midway through the 16y survey, allowing us to examine its impact and interaction effect with school climate while accounting for within-person changes over time using mixed-effects models.

Significant interaction effects were found on DS (unstandardized coefficient [B] = −0.166, 95% confidence interval [CI] −0.225 to −0.107) and PEs (B = −0.020, 95% CI −0.028 to −0.012). The pandemic effects were not significant for adolescents with high school climate scores (around the 80th percentile or higher), although the pandemic significantly worsened these outcomes among the overall sample.

The negative mental health effects of the pandemic were significantly mitigated among adolescents experiencing a supportive school climate. A positive school climate can protect adolescent mental health during challenging social conditions, such as pandemics.

No co-productive narrative synthesis of system-level facilitators and barriers to personal recovery in mental illness has been undertaken.

To clarify system-level facilitators and barriers to personal recovery of people with mental illness.

Qualitative study guided by thematic analysis. Data were collected through one focus group, which involved seven service users and three professionals. This group had 11 meetings, each lasting 2 h at a local research institute, between July 2016 to January 2018.

The analysis yielded three themes: barriers inhibiting positive interaction within personal relationship networks, roots of barriers from mental health systems and the social cultural context, and possible solutions to address the roots. Barriers were acknowledged as those related to sense of safety, locus of control within oneself and reunion with self. The roots of barriers were recognised within mental health services, including system without trauma sensitivity, lack of advocacy support and limited access to psychosocial approaches. Roots from social cultural context were also found. There were no narratives relating to facilitators. A possible solution was to address the roots from systems. Social cultural change was called for that makes personalised goals most valued, with an inclusive design that overcomes stigma, to achieve an open and accepting community.

The analysis yielded system-level barriers specific to each recovery process. Roots of barriers that need transformation to facilitate personal recovery were identified within mental health services. Social interventions should be further explored to translate the suggested social cultural changes into action.
