This research explores how the corporate social responsibility (CSR) activities of a brand can affect consumers’ purchase intention. It investigates the effects of CSR on brand attachment, brand image, and purchase intention; the effects of brand attachment and brand image on purchase intention; and the mediating effects of brand attachment and brand image on the relationship between CSR and consumer purchase intention. The empirical results support the study’s hypotheses and indicate that CSR activities significantly enhance consumers’ brand attachment, brand image, and purchase intention. Furthermore, brand attachment and brand image partially mediate the relationship between CSR and purchase intention. Additionally, we find that brand image completely mediates the relationship between CSR and purchase intention for respondents who have previously consumed products or services of the brand and are aware of their CSR activities.
