This issue of JSI focuses on interethnic marriage. Our objectives are to (1) discuss conceptual and methodological concerns; (2) examine interethnic marital relationship processes especially through the lens of interdependence theory; (3) review attitudes towards interethnic marriage; (4) assess the clinical and policy implications; and (5) synthesize the contemporary scholarship. We draw upon the subject areas of intergroup and interpersonal relations including contributions from authors across various disciplines. Given the status of interethnic marriage as a potential bellwether of social change in the United States, we believe that the present edition is as timely as it is important.
