This study examines how tension is transmitted between the marital dyad and
the parent-child dyad on a day-to-day basis and explores how stable and ch
anging aspects of the family moderate this process of tension spillover: Mo
thers and fathers (n = 117 couples) separately completed a short diary ques
tionnaire that included a checklist of common daily stressful experiences o
n each of 42 consecutive days. Hierarchical generalized linear models showe
d that both mothers and fathers were more likely to have tense interactions
with their children on days when there had been some marital tension the p
revious day. On days when fathers experienced other stressors, such as work
overloads or home demands, they were more than twice as likely to experien
ce tension spillover than on stress-free days. Fathers also reported more s
pillover when their wives were working full-time. In families with adolesce
nts in the house, mothers had more tension spillover.
