Tóm tắt	The Democratic Support Scale measures citizen commitment to democracy as a regime type, including beliefs that democracy is the best system of government, willingness to defend democratic institutions, and rejection of non-democratic alternatives. Pioneered by Norris (1999) and Dalton (2004) in comparative research, the measure distinguishes regime support (belief in democracy's superiority) from performance support (satisfaction with current government). It addresses the paradox of 'critical citizens'—in advanced democracies, people often express dissatisfaction with current government performance while maintaining deep commitment to democratic principles.	Political efficacy measures sense of personal agency and power in the political system, encompassing both internal efficacy (belief in own political competence and understanding) and external efficacy (belief that the political system is responsive to citizen input). Rooted in Bandura's self-efficacy theory (1977) and developed for political contexts by Niemi, Craig, and colleagues (1969 onwards), the measure explains why some citizens feel empowered to engage in politics while others feel powerless. High-efficacy citizens are substantially more likely to participate, contact representatives, and vote; low-efficacy citizens withdraw from politics and are susceptible to anti-democratic appeals.	The Voter Cynicism Scale measures citizen skepticism and disillusionment regarding the political process, including beliefs that the electoral system is rigged, politicians are self-serving, and voting does not matter. The measure captures a pessimistic orientation toward electoral democracy distinct from distrust in institutions (which can coexist with belief in democratic potential) or political alienation. Rooted in Campbell et al.'s American Voter (1960) tradition of measuring political efficacy and cynicism, the scale remains central to understanding voter turnout decline, support for populist alternatives, and democratic legitimacy crises.
