摘要	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.	The Political Participation Scale measures engagement in civic and political activities, encompassing voting, campaign involvement, contacting officials, organizational membership, community volunteering, and protest activity. Developed by Verba, Schlozman, and Brady (1995), the measure captures both conventional participation (voting, contacting representatives) and unconventional participation (protest, civil disobedience). It addresses fundamental questions in political science: Why do some citizens engage while others withdraw? How do structural resources (time, money, education) and psychological factors (efficacy, interest) drive participation?
