Measuring flow in gamification: Dispositional Flow Scale-2.

•Psychometric properties of the DFS-2 are examined in gamification of exercise.•A good model fit for the original DFS-2 structure is found.•A respecification of the model is created to reach higher level of goodness-of-fit.•The data suggest a division of the components of flow into conditions and outcomes.•The study also shows which components of flow are salient in gamification.
