Collective self-continuity, group identification and in-group defense

The present research tested the proposition that the sense of self-continuity that people derive from their group membership provides a basis for group identification and drives in-group defensive reactions in the context of identity threat. This proposition was examined in three studies, using the context of national identity. Study 1 found that collective self-continuity uniquely and strongly predicted national identification, when controlling for other identity motives. Studies 2 and 3 demonstrated that existential threats to national identity particularly increase a sense of collective self-continuity, compared to other identity motives, and that this enhanced sense of collective selfcontinuity results in stronger in-group defense in the form of opposition towards out-groups (Study 2) and social developments (Study 3) that may undermine group identity, as well as in stronger ingroup protectionism (Study 3). Taken together, these findings indicate that collective selfcontinuity is an important motive for group identification and in-group defense in the context of identity threat. (C) 2013 Elsevier Inc.
