Self-discrepancy and regulatory fit in avatar -based exergames

Drawing from Higgins's self-discrepancy theory and regulatory focus theory, this study examined the use of activated selves and regulatory foci in health games. Utilizing the Wii's® avatar-creating and exergaming features, a 2 (activated self: actual self versus ideal self) × 2 (regulatory focus: promotion versus prevention) × 2 (efficacy appeals: self-efficacy versus response-efficacy) betweensubjects experiment tested the interactions of activated selves, regulatory foci, and efficacy appeals on low-calorie dieting intentions after health game playing. Results from an experiment with 156 participants demonstrated that a fit between regulatory focus and efficacy appeals induced greater dieting intentions when the actual self was activated while the opposite effect occurred when the ideal self was activated. Theoretical contributions to basic and applied social psychology as well as managerial implications for consumer behavior research are considered.
