Process evaluation: All stakeholders involved in implementing the healthier school canteen will be asked to fill in an online questionnaire pre and post intervention. Demographics will be measured of stakeholders (e.g. age, gender) and school (e.g. offered education level, number of students).
The first process evaluation outcomes are perceived individual factors of the stakeholders and environmental factors that can affect the implementation process. Pre and post intervention, these individual factors (e.g. knowledge, self-efficacy and attitude regarding a healthier school canteen), as well as environmental factors affecting implementation (e.g. need for support, innovation and organisation) will be measured, based on the validated Theoretical Domain Framework questionnaire [99] and the Measurement Instrument for Determinants of Innovations [95] (Table 2.2).
The second process evaluation outcome is the quality of implementation. After 6 months, all stakeholders in the intervention group will be asked to evaluate the quality of each implementation tool. With an online questionnaire, quantitative process evaluation measures derived from the methodology of Saunders et al. [101] and Steckler and Linnan [102] will be measured. Fidelity will be measured with dose delivered and dose received. In addition, satisfaction will be measured. Dose delivered: Number of stakeholders to whom the tool was provided by the school canteen advisors. Dose received: Number of stakeholders who received and used the tool. Satisfaction: Participant’s satisfaction with each tool. Additionally, objective data collection will be conducted by digitally logging the delivery and use of each online implementation tool. Moreover, after the intervention via open-ended questions in the questionnaire and during an evaluation meeting, all stakeholders will be asked to: explain their satisfaction score; give a short evaluation per implementation tool; give their positive and negative experiences overall; and to give their suggestions for improvements (qualitative data).
