Summary

The Social Development Project (SSDP) is a prospective longitudinal study that has been in the field for over thirty years. Beginning in 1985, SSDP has followed a cohort of 808 individuals from childhood through adulthood. Within the cohort is nested a subset, who, in first grade, received an intervention that aimed to use the principals of the Social Development Model to develop pro-social behavior. Intervention effects into the thirties confirm that the original intervention has had positive effects on development and long-term health outcomes. The archived data are from waves 8, 9, and 10 of data collection, and were collected in years 1993, 1996, and 1999 respectively. In these years the cohort had an average age of 18, 21, and 24. Items included are measures of substance misuse, dependence, and addiction. Data for waves 9 and 10 are outcome and addiction variables only.

Study Purpose

The purpose of this study is to implement an intervention that aimed to use the principals of the Social Development Model to develop pro-social behavior.

Sample

In 1980, first-graders from five Seattle public schools serving high-crime neighborhoods were recruited to participate in an intervention. The intervention involved students, parents, and teachers in pro-social bonding and behavior exercises and trainings in first, second, third, and fourth grades. In 1985, the study was expanded to include 808 of 1,053 eligible fifth graders and their parents/caregivers (G2 and G1, respectively) at 18 different public schools in Seattle. An initial assessment was administered at this time. Over the next thirty years, the cohort was interviewed fourteen more times, most recently in 2014. Throughout the years, the study has been expanded to include measures of the built environment, genes, and even a third generation (G3).

The full sample consists of 808 individuals. 374 respondents consented to archiving. The sample is gender-balanced and racially and ethnically diverse: 47% identify as European-American, 26% as African-American, 22% as Asian-American, and 5% as Native American. The Seattle Social Development Project originally drew from elementary schools in low-income neighborhoods, and roughly half of the participants qualified for the National School Lunch/School Breakfast Program when the study began in 1985.
