Research on identity threat has predominantly focused on the consequences of threat to some ascribed or involuntary identities, while overlooking individuals' responses to occupational identity threat. Integrating identity theory with identity threat literature, we argue that encountering occupational identity threat promotes negative emotion and feedback-seeking behavior, and negative emotion further mediates the relationship between occupational identity threat and feedback-seeking behavior. Moreover, individuals' performance self-esteem strengthens both the direct effect of occupational identity threat on negative emotion, and the indirect effect of occupational identity threat on feedback-seeking behavior through negative emotion. The results from two experimental studies and one field study provide support for these predictions. We discuss the theoretical and practical implications of our findings.
