Resumen	Social identity measurement in political behavior applies social identity theory (Tajfel & Turner, 1979) to political groups, treating partisanship, ideology, or movement membership as a social identity rather than a mere instrumental affiliation. Huddy, Mason and Aaroe (2015) adapted Mael and Tetlock-style identity items into a partisan social-identity scale that measures expressive, emotionally charged group attachment and predicts campaign activity and political emotion better than issue agreement.	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.
