Two studies examined how the relevance of group identity influences two psychological mechanisms of collective action: Emotion- and problem-focused coping with collective disadvantage. Extending Van Zomeren, Spears, Fischer, and Leach's (2004) integrative theoretical model of coping with collective disadvantage, we predicted that when group identity is more relevant to disadvantaged group membe...

An integrative social identity model of collective action (SIMCA) is developed that incorporates 3 socio-psychological perspectives on collective action. Three meta-analyses synthesized a total of 182 effects of perceived injustice, efficacy, and identity on collective action (corresponding to these socio-psychological perspectives). Results showed that, in isolation, all 3 predictors had mediu...

Based on two proposed functions of social identity performance (Klein, Spears, & Reicher, 2007)...
