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 Civic Engagement Scale measures the extent and type of an individual's participation in civic, political, and community life. Rather than a single construct, it typically encompasses multiple dimensions: electoral participation (voting), political activity (contacting officials, campaign involvement), civic service (volunteering, organizational membership), and social participation (community meetings, neighborhood involvement). Developed by scholars including Zukin, Keeter, and Dalton, it captures how citizens actualize their democratic role.
