Collective Action Tendency Measurement (SIMCA)
Collective action tendency measurement, organized by the Social Identity Model of Collective Action (SIMCA; van Zomeren, Postmes and Spears, 2008), assesses the psychological predictors of willingness to engage in protest and group-based political action: perceived injustice (especially group-based anger), group efficacy, and politicized social identity. SIMCA integrates these three traditions into a structural model in which identity drives action both directly and through injustice and efficacy.
