خلاصه	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?	The Political Trust Scale measures citizen confidence in government institutions, elected officials, and the political system's responsiveness and fairness. Pioneered by Miller (1974) and operationalized across comparative electoral studies (CSES Module 5), the scale captures both diffuse trust (in the political system generally) and specific trust (in particular institutions such as parliament or the executive). It is central to understanding democratic legitimacy, political engagement, and support for democratic institutions.
