ABSTRACT
The third part of this volume on persuasive gaming is dedicated to validation, a process that assesses the extent to which a specific game succeeds in realizing the intended outcome. For persuasive games, this outcome by definition consists of a change in attitude and/or behavior. Our notion of validation builds upon the theoretical considerations regarding persuasive gaming as discussed in Part I and the criteria for designing persuasive games that were covered in Part II. The chapters included in Part III show that validation research is a small but promising field within game studies. The chapters also show that validation research employed different methods from the social sciences and humanities to determine the effects and impact of persuasive games.
