We propose a mid-range conceptual model integrating three somewhat disparat
e areas of research to provide an understanding of key factors that lead to
marital instability. These areas are the influence of gender on marital in
stability, the negativity and distancing behaviors in marriage, and identit
y theory. We develop and discuss a model that posits that incongruencies be
tween spouses in gender beliefs, expectations, and behaviors affect marital
instability through negative marital interactions, causing identity disrup
tion and resulting in distancing, marital instability, and, in some cases,
divorce.
