NCT04610333

Brief Summary

Our primary aim of this trial is to evaluate the effectiveness of a teacher training programme to teach mindfulness as part of regular classroom teaching in the total population of students in Danish upper secondary schools and schools of health and social care, respectively, on students' self-reported mental health at six-month follow-up. Our secondary aim is to evaluate the effectiveness of the teacher training programme to teach mindfulness in a vulnerable subgroup of students on their self-reported mental health at three and six months after baseline.
