Abstract
The present study explored the association between child internalising and externalising problems in schools and demographic factors (sex and age), school functioning (academic performance and adaptive functioning) and teacher-reported student–teacher relationship quality in a cross-sectional study using structural equation modelling. The study was conducted among a sample of Norwegian schoolchildren (n=825) in grades 1–7. The results showed among others that conflict in student–teacher relationships had the strongest association with teacher-reported child externalising and internalising problems. The school system and the teachers probably need to place more focus on how to support children with these kinds of mental health problems.
