Identity Expression Through Collective Action: How Identification With a Politicized Group and Its Identity Contents Differently Motivated Identity-Expressive Collective Action in the U.S. 2016 Presidential Elections.

Although political action often requires activists to express who they are and what they stand for, little is known about the motivators of such identity expression. This research investigates how and predict in the U.S. 2016 presidential elections. We recruited a longitudinal community sample of U.S. party supporters ( = 426) mid-October (T1), beginning November (T2), and mid-November (T3). Participants listed words they associated with party campaigners, and self-reported their identification with this identity content and the politicized group. Supporting H1, politicized group identification longitudinally predicted increased of collective action more strongly than did identification with specific identity content. Supporting H2, identification with specific identity content longitudinally predicted increased desires to that content through collective action more strongly than politicized group identification. Implications for our understanding of identity expression and identity content in collective action are discussed.
