Abstract: | Are secret romantic relationships alluring or aversive? Previous research suggests that romantic secrecy (i.e., keeping a romantic relationship secret from others) creates a cognitive preoccupation that enhances romantic attraction. In contrast, we predicted that romantic secrecy interferes with relationship interdependence and thereby decreases relationship quality. Three studies of secrecy in ongoing romantic relationships confirmed this prediction. In Study 1, romantic secrecy predicted lower levels of initial relationship quality and decreased relationship quality over a 2‐week period. In Study 2, relationship burden mediated partially the negative association between romantic secrecy and relationship quality. In Study 3, the negative association between romantic secrecy and relationship quality was primarily explained by decreased relationship satisfaction. The importance of understanding romantic secrecy is discussed. |
