Internalizing symptoms and disorders in families of adolescents: A review of family systems literature

Internalizing symptoms and disorders are relatively common during adolescence and impact considerably on social and emotional functioning. Using a family systems framework, this paper reviews the current literature examining the impact of internalizing symptoms and disorders on the functioning of the family system, the spouse subsystem and the parent–child subsystem. Moreover, literature examining the relationship between parentsʹ and adolescentsʹ internalizing symptoms and disorders is reviewed. The reviewed research demonstrates that there exists an association between internalizing symptoms and disorders and poorer functioning at various levels of the family system. Longitudinal studies have generally reported that parent internalizing symptoms and disorders predict poorer functioning in the family system as well as internalizing symptoms and disorders in adolescents. However, few longitudinal studies have examined whether adolescent internalizing symptoms and disorders predict poorer family functioning and internalizing symptoms and disorders in parents. Those that have examined such effects report mixed results. On the basis of our review, we make recommendations about future research directions. In particular, it is argued that more research on the reciprocal effects of internalizing symptoms and disorders within families is needed to better understand the antecedents and consequences of these conditions for families of adolescents.
