Sammendrag	The Partisan Social Identity Scale treats party identification as a social identity in the sense of Henri Tajfel rather than as a running tally of policy agreement. Building on Steven Greene's social-identity approach and crystallized in Huddy, Mason, and Aaroe's 2015 study of expressive partisanship, the scale adapts standard group-identification items to ask how central, important, and emotionally engaging a person's party is to their sense of self. Strongly identified partisans are shown to feel action-oriented emotions, anger when their side is threatened and enthusiasm when reassured, and to participate in campaigns more than issue-based measures of partisanship predict.	Affective polarization measurement quantifies the gap between how positively people feel toward their own political party (the in-party) and how negatively they feel toward the opposing party (the out-party). Iyengar, Sood and Lelkes (2012) showed that this affective divide has grown sharply even where issue positions have not, reframing polarization as a social-identity phenomenon of partisan like and dislike rather than ideological distance.
