The Joint Effects of Neighborhoods, Schools, Peers, and Families on Changes in the School Success of Middle School Students* Gary L. Bowen Roderick A. Rose Joelle D. Powers Elizabeth J. Glennie** Abstract: Longitudinal self-report data from 4,071 students are used to examine the degree to which students’ per- ceptions of their social environments (people and places) are associated with changes in 3 school success outcomes: school engagement, trouble avoidance, and grades. Specific variable dimensions within the neighborhood, peer, and family domains had significant effects on one or more of these school outcomes. Implications of the findings for further research and intervention practice are discussed, including the availability of a Web-based resource for link- ing these findings with evidence-based intervention and prevention strategies. Key Words: evidence-based practice, intervention research, middle school students, school success, social environment. School success is vital to youth development into competent and productive members of society, yet the rates of school failure in the United States are alarming (KewalRamani, Gilbertson, Fox, & Provasnik, 2007). A growing body of research sug- gests that students’ relationships and experiences in their neighborhood, school, peer group, and family influence specific outcomes associated with school success (Richman, Bowen, & Woolley, 2004). Moreover, the particular configuration of assets and resources in these social environments may affect an individual differently over time (Anderson, Sabatelli, & Kosutic, 2007). Consequently, it is important to identify those aspects of the social environment that can be leveraged at particular times in the develop- mental life span to promote school success. Using longitudinal data, the present research examines how middle school students’ perceptions of hypothesized assets in their social environments influence their perceptions of three school success outcomes—school engagement, trouble avoidance, and grades—over a 12-month period. All student- level data are self-reported and are derived from repeated administrations of the School Success Pro- file (SSP) in 11 middle schools. The SSP is an eco- logically oriented survey that assesses students’ perceptions of microlevel processes in their neigh- borhoods, schools, families, and peer groups. The present study supplements youth development scholars’ increasing examination of the combined effects of multiple influences from the neighbor- hood, school, peer group, and family on adolescent *This article was prepared with grant support from the William T.
