PurposeThis study aims to propose and test an appraisal theory-based framework that depicts the impact of negatively valenced brand personality dimensions on brand hate development and the resultant outcomes of non-purchase intention and anti-brand actions. The study also delineates the moderation effect of Big Five consumer personality traits on brand personality-brand hate relationship.Design/methodology/approachAn international sample of 370 brand haters was collected and analysed with partial least square-based structural equation modelling.FindingsBoth negatively valenced brand personality dimensions of responsibility and activity are significant predictors of brand hate in consumers, and this brand hate leads to outcomes of anti-brand actions and non-purchase intention of consumers. Moderation analysis delineates that the consumer personality trait of neuroticism significantly moderates the relationship between both brand personality dimensions and brand hate. The study also established the importance of national culture in defining consumers’ behavioural intentions.Originality/valueThis study provides a novel appraisal theory-based integrated framework to understand the relationship between cognition of brand personality, brand hate emotional state and behavioural actions of consumers. To the best of the authors’ knowledge, this study is the first to consider the impact of these personality dimensions on brand hate development while assessing the interaction effect of consumer and brand personality dimensions on brand hate development.
