Evaluation of the Motivation Process 5 113 Motivating Influence Agents to Drink More Water Them- selves Regarding the training process of motivating the influence agents, the influence agents on average reported significantly higher intrinsic motivation to drink water after the training as compared to before the training, t (26) = − 2.31, p = .029 (see Table 5.2), with 74% of the influence agents showing an increase. In addition to higher intrinsic motivation, the influence agents also reported drinking marginally significantly more water after the training compared to before the training, t (26) = − 1.89, p = .070 (see Table 5.2), with 67% showing an increase. The influence agents did not drink significantly fewer SSBs after the training as compared to before the training, t (26) = .88, p = .385 (see Table 5.2); however, about half (52%) of the influence agents did show a decrease. The open-ended responses of the influence agents suggest that the technique of providing meaningful rationales motivated the influence agents to drink more water themselves. Specifically, most (47%) of the influence agents indicated that the word web in combination with the interactive presentation—in which the meaningful rationales to drink water were discussed—were the most enjoyable aspects of the training: “I liked the presentation the most [about the training].” Girl, 10 years old “I liked the most [about the training] that you can get handsome for free from drinking water and that you can get beautiful teeth.” Boy, 12 years old “The interactive presentation, for example, guessing how many sugar cubes there are in a 250 ml coca cola can.” Boy, 10 years old
