概要	The Relative Deprivation Scale measures the subjective sense that one's own group (fraternal/group relative deprivation) or oneself (egoistic/individual relative deprivation) is unjustly worse off than a relevant comparison standard, accompanied by feelings of resentment. Building on Runciman (1966) and synthesized by Smith and colleagues (2012), it captures the three-component process, cognitive comparison, appraisal of injustice, and affective resentment, that links inequality to political action.	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?
