About this trial
The purpose of this study is to evaluate the effectiveness of the MEST work strategy in upper secondary schools. MEST is a school based, health promoting intervention delivered by school health services and designed to strengthen students' health literacy and mental well being. The study assesses whether implementation of the MEST work strategy results in improved health literacy and mental well being compared with usual school health services.
This study is a cluster randomized superiority trial in which upper secondary schools are assigned either to an intervention group implementing the MEST work strategy or to a control group continuing with school health services as usual. Student reported outcomes are collected using digitally administered questionnaires during school hours at baseline, prior to initiation of the intervention, and at 4 and 9 months following intervention initiation (end of the school year).

MEST Work Strategy
Other interventionThe MEST work strategy is needs based and adaptive. An anonymous, digitally administered MEST survey conducted prior to intervention initiation informs the selection and tailoring of intervention topics throughout the school year. This survey is used solely to guide intervention delivery and is not included in the outcome evaluation. Intervention activities may include classroom based sessions, school wide seminars, small thematic group activities, and individual consultations provided by the school health services, depending on identified student needs. All activities are conducted on school premises using existing school facilities and digital infrastructure.
