خلاصه	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 Partisan Identity Scale measures strength and direction of psychological attachment to a political party, encompassing both party preference and emotional party identification. Foundational since Campbell et al.'s American Voter (1960), the measure distinguishes party affiliation (which party one is registered with) from party identification (psychological identity with a party as a social group). Partisan identity is among the strongest predictors of voting behavior, political attitudes, and interpretation of political information, functioning as a 'perceptual filter' through which voters process news.
