This study examines the interactive effects of self-esteem, contingencies of self-worth, and ego threat on supportiveness and liking. Targets high or low in self-esteem and academic contingency receive failure test feedback or no evaluative feedback. Then, targets interact with another participant who discloses a personal problem; afterward, both participants complete questionnaires assessing targets' supportiveness and liking. High self-esteem, highly contingent targets feel less supportive and like partners less after interacting under threat than under no threat. Partners, in turn, perceive these targets to be less supportive and less likeable. Low self-esteem, highly contingent targets show the reverse pattern, although these findings do not reach statistical significance. Further analyses reveal that the interpersonal effects of ego threat were caused by threats in a specific domain of contingency (e.g., academics) rather than being a contingent person in general or having external or internal contingent self-worth. Implications for self-esteem and interpersonal processes are discussed.
