Tóm tắt	The Political Knowledge Scale measures the range of factual information about politics that citizens hold and can retrieve, operationalized as a battery of factual quiz items. Delli Carpini and Keeter (1993, 1996) established the canonical short batteries (often five items) and argued that general political knowledge, not domain-specific information, is the most useful and reliable construct for survey research.	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?
