The Seattle Social Development Project has produced important findings on the development of alcohol abuse and dependence, on risk factors for school dropout, violence and gang membership, and on long-term effects of preventive intervention in the elementary grades. The Seattle Social Development Project has generated many studies drawing on the same panel of participants.
Substance Use and the Consolidation of Adult Roles (SSDP)
Currently, the Seattle Social Development Project (SSDP) has completed the age 30 data collection having interviewed 91% of the original fifth-grade sample, and we are in the field interviewing participants at age 33! Our analyses have focused on examining development during period of emerging adulthood (18-24), and the factors that affect successful transition to and consolidation of adult roles in the 20s and 30s. In addition, we are examining factors that influence young adult health behaviors and health outcomes. Current papers include analysis of long-term effects of the SSDP intervention at ages 24 and 27, and examination of positive adult behavior, alcohol abuse and dependence trajectories and health outcomes into the 30s.Start Date: 1986

The Intergenerational Influence of Substance Use on Children (TIP)
Many of the members of the Seattle Social Development Project (SSDP) sample are now raising children of their own. The SSDP Intergenerational Project (TIP) is a study to extend the SSDP panel by examining the effects of past and current parental substance use on development in the subsequent generation. Participants in TIP include those SSDP participants actively parenting a biological child, their oldest child and an alternate caregiver (typically the spouse). Data collection is annual and tied to the child’s birthday. Currently the Intergenerational Project is examining data from the first five years of the study to examine the intergenerational
transmission, influence, and consequences of substance use on child developmental progress and difficulties, parenting practices and
family conflict. By studying the patterns and mechanisms of intergenerational transmission of substance use as well as the
intergenerational consequences of positive adult development, these studies will aid in the development of preventive interventions
aimed at breaking cycles of intergenerational transmission of problem behaviors.

Psychopathology and Health Risk Behavior Into Adulthood. (Adult Development and Mental Health - ADAMH)
This study examines the course, consequences, predictors, and prevention of depression, social phobia, and generalized anxiety, as well as their co-occurrence with risk for human immunodeficiency virus (HIV) infection and substance abuse and dependence in young adulthood in the SSDP sample through age 33. Analyses focus on the longitudinal patterns of these outcomes in the 20s and 30s, and the consequences of these patterns for healthy adult functioning, including positive behavior, physical health, and utilization of health services. Analyses include an examination of the effects of patterns of depression and anxiety on HIV risk. The study also examines the role of social developmental processes and proximal stressful life events in explaining patterns of depression and anxiety and their co-occurrence with HIV risk and substance abuse/dependence in young adulthood, as well as the long-term effects of the SSDP intervention in the elementary grades on these patterns.Start Date: 2006
