概要	The Democratic Values Scale measures commitment to core principles of democratic governance including free speech, rule of law, fair elections, protection of minorities, and transparent institutions. Rather than measuring support for democracy as a system (which is nearly universal in principle), it captures depth of commitment to democratic norms, tolerance for dissent, and willingness to protect rights of political opponents. Developed by comparative political scientists including Dalton, Klingemann, and Welzel, it reveals psychological foundations of democratic stability.	The Institutional Trust Scale measures an individual's confidence and trust in formal political and social institutions including parliament, courts, police, media, and civil service. Distinct from generalized interpersonal trust, institutional trust reflects belief in the legitimacy, fairness, and effectiveness of formal organizations that structure governance and public life. Developed in political science by scholars including David Easton and Marc Hetherington, it is a key indicator of democratic health and governance legitimacy.
