Clark and Mills (2012) proposed that communal norms characterize “healthy marriages,” whereas exchange norms indicate “troubled” ones. Using the actor–partner interdependence model, we consider this proposal. Heterosexual married partners’ exchange and communal strength are examined with several relational features including trust, commitment, relational satisfaction, and control mutuality, as well as partner-specific tendencies toward forgiveness. The findings indicate that one’s communal strength is associated with positive relational features for both oneself and one’s spouse, as well as a greater propensity to forgive and lesser tendencies toward negative forgiveness (retaliation). Exchange strength was generally associated with negative forgiveness. However, the relationship between exchange strength and relational features is more complicated. Lesser communal strength was generally associated with lower levels of the relational characteristics. Yet, exchange and communal strength interacted, indicating exchange may play a protective function by buffering against the ill effects of a lack of communal strength for some relational characteristics.
