概要	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.	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.	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.
