Reflection is generally considered an effective means of achieving behavior change. A gamified approach to promoting rehearsal and reflection in a healthy eating context was studied. The game was based on the principles of the Implicit Attitude Test: by categorizing food items under positive or negative associations the players would gain points according to how fast they categorized foods under positive or negative associations. Game scores constituted feedback for reflection, and repeated playing constituted rehearsal of target responses. Experiment participants (N=58) played the game over a five-day period. Constructs of Rehearsal (REH), self-reported questionnaire responses on Reflection (REFL) and Perceived Persuasiveness (PEPE), and self-reported Perceived Health Behavior Change (PHBC) were analyzed using PLS-SEM. The results show that PLAY moderates the REFL-PEPE relationship, and there are also significant relationships between REH and PEPE, PEPE and PHBC, and REFL and PHBC.
A gamified approach to promoting reflection and to engaging users in rehearsing decision-making in a dietary context was studied. The game was based on the principles of the Implicit Attitude Test, but was not a complete IAT in itself like the original test at projectimplicit.net: by categorizing food items under positive or negative associations the players gained points according their categorization speed but the score was merely indicative of attitudinal alignment with the target response. Showing the scores was a vehicle for reflection, and repeated playing constituted response rehearsal. Research questions: 1) does a gamified process of drawing attention to implicit attitudes evoke self-reflection, 2) does gamification of response rehearsal contribute positively to behaviour change? We expected the exposure to one's own choices in the game to heighten the awareness of personal food choices. Experiment participants (N=58) played the game over a five-day period. Constructs of Rehearsal, Reflection, Perceived Persuasiveness, and Perceived Health Behavior Change were analyzed using PLS-SEM. The findings point to rehearsal having a role in how reflection and perceived persuasiveness are connected. Reflection was involved in the self-reported behaviour change, and perceived persuasiveness can promote behaviour change. Open-ended questions showed awareness of choice having a behavioural effect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
