Promoting Positive Adult Functioning Through Social Development Intervention in Childhood: Long-term Effects from the Seattle Social Development Project

This Web site describes the Seattle Social Development Project (SSDP), which is a long-term study of the development of positive and problem behaviors among adolescents and young adults. Each year through the elementary grades, parents and teachers in intervention classrooms learned how to actively engage children in learning, strengthen family and school bonding, and encourage positive behaviors. The Project is currently preparing to interview its sample again at age thirty. Interview information is used to examine youth development and the causes and consequences of risky behaviors.
