สรุป	The Democratic Support Scale measures citizen commitment to democracy as a regime type, including beliefs that democracy is the best system of government, willingness to defend democratic institutions, and rejection of non-democratic alternatives. Pioneered by Norris (1999) and Dalton (2004) in comparative research, the measure distinguishes regime support (belief in democracy's superiority) from performance support (satisfaction with current government). It addresses the paradox of 'critical citizens'—in advanced democracies, people often express dissatisfaction with current government performance while maintaining deep commitment to democratic principles.	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.
