概要	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.	The Generalized Trust Scale measures an individual's propensity to trust people in general, particularly strangers with whom they have no direct relationship. Originally developed by Morris Rosenberg in 1956 and later refined by Toshio Yamagishi and colleagues, it has become foundational in research on social capital, civic participation, and intergroup relations.
