概要	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.	The Media Trust Scale measures audience confidence in news media credibility, including perceptions of accuracy, fairness, completeness, and journalists' motivations. Developed by West (1994) and extended by Kiousis (2001), the scale captures both medium-specific trust (trust in TV news vs. newspapers vs. online news) and outlet-specific trust (CNN vs. Fox News vs. BBC vs. local news). Media trust is central to understanding political polarization, misinformation vulnerability, and the functioning of the democratic public sphere, as low-trust populations reject news sources entirely, opening space for alternative information ecosystems.
