Σύνοψη	The Post-Materialism Index, developed by Ronald Inglehart (1971), classifies individuals as materialist, postmaterialist, or mixed based on the priority they assign to physical and economic security versus self-expression, belonging, and quality of life. It operationalizes Inglehart's silent-revolution thesis that prosperity and security in postwar democracies caused an intergenerational shift from materialist to postmaterialist value priorities.	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?
