Family functioning was investigated as a mediator between interparental con
flict and adolescent depressed mood among adolescents living in two-parent
and divorced families. Data were collected three times, with one year inter
vals. At the initial interview, adolescents were, on the average, 15.5 year
s old. Two types of interparental conflict were assessed: interparental con
flict involving arguments about the adolescent, and arguments focused on th
e parents' behaviors. The results confirmed that family functioning mediate
d the effects of parent issue/interparental conflict, but not adolescent is
sue/interparental conflict. This was most evident for girls than boys. Impl
ications of the findings for research and practice are discussed.
