Summary	The Nationalism and Patriotism Scale, introduced by Kosterman and Feshbach (1989), distinguishes patriotism (love of and attachment to one's nation) from nationalism (belief in national superiority and a desire for dominance over other nations). It established that national attachment is not a single attitude but a set of separable dimensions, a distinction later extended by Schatz, Staub and Lavine (1999) into blind versus constructive patriotism.	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.
