CD38 is associated with bonding-relevant cognitions and relationship satisfaction over the first 3 years of marriage

Abstract Although there are numerous benefits to having a satisfying romantic relationship, maintaining high levels of relationship satisfaction is difficult. Many couples experience declines in relationship satisfaction in the early years of marriage, and such declines predict not only relationship...
