This scoping review seeks to integrate disparate research on the role of similarity in romantic relationships, a topic of long-standing interest among researchers and popular culture alike. We offer a synthesis of 339 articles measuring similarity and relationship outcomes in established romantic relationships. We report trends in extant research regarding domains of similarity, methods of calculating similarity, and sample characteristics.
