2.5. Recruitment Procedure

The data collection consisted of two phases. In the first phase, non-participant observations and informal interviews were conducted. In the second phase, in-depth interviews and focus groups were conducted. The researchers explained the purpose and design of the study to the school principal and students during an initial face-to-face contact session. Separate information sessions were held for students, their legal guardians, and the health and education professionals. During these meetings, the study was described and questions were answered. Finally, participants were invited to participate in the study. All the informative sessions were held at the APACE school.
