Rewarding Healthy Food Choices: a Mobile Serious Game Intervention in Adolescents

The REWARD intervention is based on the dual process model incorporating strategies to influence both the automatic pathway (i.e., operant learning theory) and the conscious pathway (i.e., a focus on certain determinants). The central idea of the intervention will be that participants will earn credits in the game when scanning healthy (rather than unhealthy) snacks which will influence the advancement of the players in the game. This credit system will be related to the dietary quality index of the consumed snacks.
