สรุป	The National Identity Scale measures the strength and character of individuals' identification with their nation, including attachment to national symbols, pride in national achievements, and sense of belonging to the national community. Developed by Kosterman and Feshbach (1989), it distinguishes patriotism (pride in national accomplishments, willingness to serve) from nationalism (belief in national superiority, willingness to act against outsiders). The measure has become essential in comparative politics, examining how national identity shapes political behavior, attitudes toward immigration, support for international cooperation, and electoral choices.	The Political Ideology Scale measures individual self-placement on a left-right political spectrum, capturing fundamental preferences for government role, economic organization, and social values. The single-item self-placement measure (most common) asks respondents to rate themselves on a 0-10 or 0-100 continuum; multi-item versions assess distinct ideological dimensions (economic policy, social policy, nationalism). The left-right axis remains the dominant organizing principle of political competition globally, predicting party choice, policy preferences, and electoral behavior despite critiques that it oversimplifies multidimensional political space.	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.
