Welcome to the Child Development/Adolescent Development Project Homepage!

The Child Development Project (CDP) is a multi-site, longitudinal research program aimed at learning more about the processes involved in child and adolescent development.

The study emphasizes research on social, emotional and scholastic development of children and adolescents as well as how various family, peer, school and neighborhood factors impact development.

The project commenced in the summer of 1987, with a second cohort recruited in the summer of 1988. Since year one of the project, yearly assessments have been conducted with participants, their families, and their friends. Currently the CDP is in its 20th year of data collection.
