 The study aims to capture the current state of conceptualizations of gamification and serious games in health care research and provide tools for researchers to disambiguate the reporting of game-based interventions, finding that less than half of the concept mentions are accompanied by an explicit definition and identifying four common approaches to distinguish between the two concepts. The study developed a set of guidelines called Gaming for Rigorous Reporting on Study Results of Game-Based Interventions.
