In this paper, we present the development and validation of an instrument for measuring users’ gameful experience while using a service. Either intentionally or unintentionally, systems and services are becoming increasingly gamified and having a gameful experience is progressively important for the user’s overall experience of a service. Gamification refers to the transformation of technology to become more game-like, with the intention of evoking similar positive experiences and motivations that games do (the gameful experience) and affecting user behavior. In this study, we used a mixed-methods approach to develop an instrument for measuring the gameful experience. In a first qualitative study, we developed a model of the gameful experience using data from a questionnaire consisting of open-ended questions posed to users of Zombies, Run!, Duolingo, and Nike+ Run Club. In a second study, we developed the instrument and evaluated its dimensionality and psychometric properties using data from users of Zombies, Run! (N = 371). Based on the results of this second study, we further developed the instrument in a third study using data from users of Duolingo (N = 507), in which we repeated the assessment of dimensionality and psychometric properties, this time including confirmation of the model. As a result of this work, we devised GAMEFULQUEST, an instrument that can be used to model and measure an individual user’s gameful experience in systems and services, which can be used for user-adapted gamification and for informing user-modeling research within a gamification context.

This study investigates the effect of gamification on in-store mobile advertisement. More specifically, it investigates the effect of gamification on the inclination to act on offers gained at point of purchase. For this purpose, a field experiment was conducted at a supermarket, where real customers were recruited. Eye tracking, smartphone activity logging and choice were used to investigate the customers’ behaviour. The results reveal that gamification is not always useful for increasing the tendency to act on offers. In fact, engagement in a gamified shopping task is needed; otherwise, the tendency to act on offers might even decrease when gamifying.

The purpose of this study is to understand how gamification contributes to customers’ value creation in a retail context and how this value creation relates to brand engagement. The study builds on a field experiment using a two-group between-subjects design combined with correlational research. The experiment involved 378 participants recruited at a major European sports retailer. Participants were exposed to one of two conditions: one with a gamified activity in a store, and one in which the participants performed the same activity without being exposed to any game elements. The findings show that gamification affects the hedonic value of an activity and that this effect can be partly explained by positive affect. When this hedonic value was compared to the satisfaction with a reward, the hedonic value was found to be a better predictor of continued engagement intention. Finally, gamification through continued engagement intention is positively associated with brand engagement.
