The effects of a psychological brand contract breach on customers' dysfunctional behavior toward a brand

Purpose: This paper introduces the concept of dysfunctional customer behavior toward a brand and argues that when customers perceive that a brand has failed to fulfill its promises, a psychological brand contract breach occurs, which in turn leads to a psychological brand contract violation, which evokes dysfunctional customer behavior toward the brand. In addition, this study investigates whether the impact of a breach of this contract is dependent on brand relationship quality, brand apology and restitution. Design/methodology/approach: Study 1 conducted the online survey and 224 respondents were used for data analysis and the moderating role of brand relationship quality was examined. Study 2 conducted an experiment with 201 participants to test the moderating role of brand apology and restitution. Findings: This study found the moderating role of brand relationship quality, brand apology and brand restitution on the relationship between a psychological brand contract breach and dysfunctional customer behavior toward a brand (i.e. brand-negative word-of-mouth, brand retaliation and brand boycott), which is mediated by psychological brand contract violation. Originality/value: This study contributes to the theoretical understanding of dysfunctional customer behavior toward a brand by integrating the literature on brand management with the organizational literature on psychological contracts between organizations and their employees. Furthermore, this study sheds light on the effectiveness of reparative actions by the firm after occurrence of the psychological brand contract breach.
