Chapter 5—Promoting water consumption among Dutch children: An evaluation of the social network intervention Share H 2 O The aim of the study described in Chapter 5 was to evaluate the process of motivating the influence agents, and via them, their peers, to develop healthy drinking behaviors. This chapter describes a study that evaluates the process of implementing the Share H 2 O social network intervention, in (1) motivating influence agents to drink more water themselves and (2) supporting them in motivating their peers to drink more water. The evaluation was based on the theoretical framework of the self-determination theory which guided the design of the Share H 2 O training. To evaluate the implementation of the Share H 2 O social network intervention, reports from both the influence agents ( N = 37; 48.6% girls; M age = 10.95, SD age = .94) and the peers ( N = 112; 47.3% girls; M age = 10.84, SD age = 1.04) in the networks of the influence agents were used.
