General Discussion 6 129 Aim 3 (Chapter 4)—Compare the effectiveness of the improved Share H 2 O social network intervention to a mass media intervention and no intervention • Children exposed to the improved Share H 2 O social network intervention consumed less SSBs than those who received no intervention. There was a trend for children exposed to the social network intervention to consume less SSBs compared to those who received the mass media intervention. • The effectiveness of the improved Share H 2 O social network intervention on children’s water consumption depended on social norms. Specifically, children with initially higher perceived descriptive norms and lower perceived injunctive norms increased their water consumption after the intervention. Aim 4 (Chapter 5)—Acquire an in-depth understanding of the underlying processes of motivating influence agents, and via them, their peers, to adopt healthy drinking behaviors • The design of the Share H 2 O social network intervention fostered an autonomy- supportive climate, enhancing the influence agents’ intrinsic motivation to drink water. Providing meaningful rationales based on short-term outcomes to drink water seemed to have particularly motivated them. • Influence agents mainly used face-to-face strategies, such as modeling, talking with peers, and providing social support, instead of online strategies to promote water consumption among their peers. • After the Share H 2 O intervention, the targeted peers experienced more social support and felt that their classmates thought they should drink more water. In addition, their intrinsic motivation to drink water did not increase. REFLECTIONS ON THE MAIN FINDINGS In the following sections, we discuss and reflect on the above findings based on the two main perspectives in the theoretical framework of this dissertation. First,
