This article proposes a procedural model designed to optimize the experience of citizens in decision making of public policies through gamification. The study assumes that gamification increases motivation and contributes to increase involvement within a specific area. In this case, gamification is used to encourage citizens’ engagement in decision-making, based on three models of evaluation of public policies that incorporate civil participation in three different roles: auditor, passive and active. After applying the Delphi methodology, the results of reliability and internal consistency show that experts attribute a higher value to the model of active participation using gamification. In conclusion, the model designed opens a new area of knowledge within the evaluation of public policies, embedded in the interactivity of the media context.
