This study examined how open communication between spouses may buffer against discrimination experienced by Black–White couples. Results from 178 couples analyzed using a combination of common‐fate and actor–partner interdependence models, indicated that for Black partners, marital satisfaction was not contingent on the level of openness when experiences of couple discrimination were low. When experiences of couple discrimination were high, levels of marital satisfaction were maintained among partners who reported high openness and reduced among partners who reported low openness. Moderation effects were not found for White partners. The results suggest that because Black partners are more aware of and sensitized to discrimination, White partners’ abilities to attune to their partners’ needs for support could help enhance their relationships.
