In this paper; we examine whether people's beliefs about the permanence, de
sirability, and importance of marriage moderate the impact of marital trans
itions-including marital losses and gains-on depression, a disorder associa
ted with both marital status and role transitions. Using two waves of panel
data from the National Survey of Families and Households (N = 10,005), we
find that a marital loss results in increased symptoms, whereas a marital g
ain results in decreased symptoms. We also find, however, that the negative
effects of a marital loss are greater for people who believe in the perman
ence of marriage than they are for those who do not. Conversely, the positi
ve effects of a marital gain are greater for people who believe in the desi
rability anti importance of marriage than they are for those who do not. Ou
r results highlight the potential utility of more systematically incorporat
ing people's beliefs-and sociocultural factors more generally-into theory a
nd research on the impact of stressors on mental health.
