Research on attributions in marriage rests on 2 assumptions. First, the att
ributions spouses make for their partners' behaviors have been treated as a
style or a trait, reflecting enduring aspects of the perceiver. Second, at
tributions have been described as a causal factor in the development of the
marriage over time. To evaluate the evidence for these assumptions, the au
thors analyzed 8 waves of longitudinal data from a sample of newlywed coupl
es. Results offered no support for the idea of an enduring attributional st
yle; attributions changed linearly, and changes in attributions were strong
ly associated with changes in marital satisfaction within each spouse. Neve
rtheless, controlling for these associations, initial levels of attribution
s predicted changes in marital satisfaction more than initial satisfaction
predicted changes in attributions. Effects of neuroticism and effects on ma
rital dissolution were also examined.
