This research investigated the relationship between the length of women's m
aternity leave and marital incompatibility, in the context of other variabl
es including the woman's employment, her dissatisfaction with the division
of household labor, and her sense of role overload. Length of leave, work h
ours, and family salience were associated with several forms of dissatisfac
tion, which in turn predicted role overload. Role overload predicted increa
sed marital incompatibility for experienced mothers but did not for first-t
ime mothers, for whom discrepancies between preferred and actual child care
were more important. Length of maternity leave showed significant interact
ions with other variables, supporting the hypothesis that a short leave is
a risk factor that, when combined with another risk factor, contributes to
personal and marital distress.
