||Previous research has found that individuals often adopt traits of important social groups into their own self-concepts. Additionally, those who exhibit more interdependent self-construals are more likely to define themselves in relation to their social relationships and groups. Recent evidence has found that when individuals are threatened with the loss of an important group membership, they experience changes in the self-concept. The present study examined whether group identification and self-construal effected these threat-induced changes in the self-concept. Fifty-eight Villanova upperclassmen were primed with either high or low group identification and an interdependent or independent self-construal. Participants were then asked to imagine losing their Villanova group membership. Group importance was not found to have an effect on changes in the self-concept. However, those with an interdependent self-construal were more likely to experience lowered self-concept clarity and self-esteem and increased depression following the threat. Implications and directions for future research are discussed.
