Chapter 2. Study protocol
Stakeholders: In the participating schools, all stakeholders involved in implementing a healthier school canteen will be asked to fill in questionnaires at baseline and after the intervention. These stakeholders will be identified by our contact of the school. The number of stakeholders and their function will differ per school, due to organizational differences between schools. Involved stakeholders may include: teachers, students, representatives of the school board/school canteen, students and health promoters of the Community Health Service.

Students: In each of the participating schools, 100 second or third-year (aged 13-15 years) students will be included. Therefore, approximately four second-year classes will be invited to participate, reflecting the education levels offered at the school. Students will be asked to fill in a questionnaire, at baseline and after the intervention. Two weeks prior to the questionnaires, parents and students will receive an information letter, and the option to decline participation. Per school, four vouchers of €25 (for an online goods shop) will be raffled off among all participating students.
Intervention
The implementation plan, consisting of various implementation tools, was developed as described before. Some existing tools were adapted and others were newly developed in collaboration with stakeholders from research, policy and practice. This resulted in a mix of implementation tools (Table 2.1): a questionnaire to gain insight in stakeholders’
