In this article, we introduce the concept of family integration to describe
the way in which family social organization affects individuals. We hypoth
esize that when parents are integrated into the family, it benefits their c
hildren's development of self. Using panel data, we test three mechanisms o
f parental family integration-activities within the home, family social net
works, and family support networks. The results show that parental family i
ntegration early in a child's life has positive effects on the child's self
-esteem in early adulthood, 23 years later. These findings provide importan
t new insights into both the social processes affecting self-esteem and the
long-term consequences of various dimensions of family integration.
