The current study investigated peer relationship and school climate factors associated with adolescent mental health. Cross-sectional data from 2,571 fifteen-year old students in 22 Scottish secondary schools was used. Multilevel models tested for school differences in mental health, and nested linear regression models estimated peer and school effects. Results demonstrated no significant between-school variation in mental health. Peer victimization was the only peer effect associated with mental health. School-belonging, student-teacher relationships, and a perceived inclusive school climate were associated with better mental health, whereas a perceived school climate of exam pressure was associated with worse mental health. The findings highlight multiple aspects of school climate that could be targeted in school-based interventions for adolescent mental health.
