Consumers’ negative emotions may be the main cause of behaviors such as complaining, negativeword of mouth, and brand switching. In this regard, factors other than brand can produce negative orpositive emotions toward a brand. One such factor is corporate social irresponsibility (CSIR). Thisstudy seeks to extract negative emotions toward a particular brand (auto brand). The results show thatconsumers’ negative emotions toward the auto brand are mainly characterized by anxiety, discontent,and anger. Also, the study model indicates a significant positive correlation between consumers’negative emotions and their behavioral approaches (e.g., complaining, negative word of mouth, brandswitching). On the other hand, the model represents the mediating role of negative word of mouth inbrand switching. Finally, this study investigates the moderating role of CSIR and shows that it canincrease the possibility of brand switching in consumers up to 40%.
