This article describes the social psychological process that underlies the cultural transition of sojourners. Herein the empirical and theoretical literature on cultural transitions (and in particular cultural repatriation and the relevant literature on self-concept and identity) is analyzed, critiqued, and synthesized in an attempt to understand the near ubiquitous distress experienced during repatriation. The relation among self-concept, cultural identity, and cultural transitions is explored, and in light of the paucity of comprehensive repatriation models, a new predictive model is proposed that explicates these relations. Shifts in cultural identity are classified as subtractive, additive, affirmative, or intercultural, and research directions are suggested.
