Influence of Congruency between Ideal Self and Brand Image on Sustainable Happiness

Building on the Sustainable Happiness Model, this study examines how congruency between ideal self-concepts and brand image influences a sense of happiness. The findings show that when the ideal self-image and the ideal social self-image are congruent with brand image, a sense of happiness can be enhanced through brand identification and positive emotions. An additional two-mediation analysis confirms that there are full mediation effects of brand identification and positive emotions between ideal self/ideal social self-brand congruency and happiness. This study contributes to the literature as it reveals the mechanism of how congruency between ideal self-concepts and brand image positively affects happiness. In addition, this study also provides useful insights for business practitioners as previous studies suggest that enhancing consumer well-being helps increase firms’ long-term sustainability in many ways.
