Methods: Data were derived from the Swedish Health Behaviour in School-aged Children (HBSC) study of 2017/18, with information collected among 1,418 students in grade 9 (∼15-16 years). School demands, teacher support, and classmate support were measured by indices based on three items each. Mental well-being was measured by the Short Warwick-Edinburgh Mental Wellbeing Scale (SWEMWBS). Linear regression analyses were performed. Results: Higher demands were associated with lower mental well-being. Conversely, mental well-being increased with greater teacher support and classmate support. Interactions between demands and the support variables showed that at the lowest levels of teacher and of classmate support, mental well-being was low and not associated with school demands. With increasing levels of teacher and classmate support, the overall level of mental well-being increased and revealed an inverse association between school demands and mental well-being. Conclusion: The study contributes with knowledge about how psychosocial conditions in school may hinder or enhance well-being among students.
