תקציר	Group identity measurement assesses the strength and structure of a person's psychological identification with a social group, such as a party, nation, ethnic group, or movement. The Leach et al. (2008) hierarchical multicomponent model is a leading approach, decomposing in-group identification into self-definition (individual self-stereotyping, in-group homogeneity) and self-investment (solidarity, satisfaction, centrality), measured by a validated 14-item scale.	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.
