2.2.1. Development of the GT Program
From January 2020, the Judlin De Bouville (JDB) Foundation, as part of its Antéïa Preventive Center, gathered an expert committee in order to develop a school-based educational intervention to promote healthy active living through the use of a collaborative game among primary school children. Public health policymakers (representative of the rectorate and national education cabinet in charge of the primary school policies), preventive education specialists, school nurses, academic and school leaders, and teachers as well as physicians, research scientists, and methodologists were then gathered. Individual interviews and collective meetings gathering specific subgroups to discuss specific questions (e.g., elaboration of the design with researchers and methodologists) were conducted. General meetings gathering the entire expert panel were also conducted. Two main coordinators from the JDB foundation attended all the meetings and conducted all the interviews. From this effort, the GT game was developed, the materials and tools developed and an evaluation process was planned. The entire timetable and material were then presented to the expert panel for final validation.
