Once eligibility was confirmed, parents and adolescents completed baseline measures, and all participants received a package containing a scale, measuring tape, activity tracker (Fitbit), and brochure with current health recommendations. Once baseline measures were completed, participants were randomized and provided with a CAD $60 (US $46) incentive for e-transfer. A computer-generated randomization schedule was used to allocate participants into blocks of 4, 6, or 8 participants with a randomization ratio of 1:1 [The allocation schedule was concealed in the randomization module of REDCap and only assigned after informed consent and baseline assessments were obtained. Research team members did not enter or modify the allocation schedule; they were exclusively computer generated. Participants were not blinded to their allocation conditions, and allocation assignments were not concealed from researchers at the analysis stage.
