2.5.4. Monitoring of the Intervention and Outcomes
Researchers and research assistants visited one quarter of the randomly chosen sessions to verify programme fidelity. The mentors were reminded if the observers noticed students who were not participating in the sessions. The testing revealed that the mentors could follow the semi-structured curriculum and PYD principles. Metrics were constructed into the physical training timetable so the group members could easily obtain and keep a record of them. All of the chosen school systems were given an evaluation day scheduled with the school principals. Throughout the week before the day set aside for the evaluation, all of the participants were informed about the procedure and given written material fortheir parents or guardians [Meanwhile, the students in the control group were asked to access a web-based health education game with 400 questions on healthy lifestyles during the study period. The university’s computer room was provided to thosestudents without internet or computer access. Similarly, students were not allowed to interact in order to minimise bias.
