Integrative Statement

High levels of aggressive behaviors in early adolescence are associated with a host of problematic short- and long-term outcomes, including school drop-out, substance use, mental health problems, and delinquency (Baker, 2013; López-Romero, Romero, & Andershed, 2015). Growing up in poverty increases youth risk for developing aggressive behavior problems (Evans, Gonnella, Marcynyszyn, Gentile, & Salpekar, 2005). In part, this appears due to exposure to school contexts that are characterized by high levels of student poverty and low levels of student achievement, which can create socialization contexts that support aggression and impede the development of adaptive self-regulation skills. For example, when there are many aggressive children in the peer group, students are exposed to aggressive models and peer support for aggressive behaviors (Dishion & Tipsord, 2011; Powers, Bierman, & CPPRG, 2013). In addition, disorganized classrooms, demoralized teaching staff, and negative student-teacher relationships at these schools often contribute to the development of student aggression (Bradshaw, Sawyer, & O’Brennan, 2009; Myers & Pianta, 2008). Several studies have documented associations between student aggression and school contexts characterized by high levels of student poverty or low levels of student academic achievement, but rarely have studies examined these contexts together using a developmental lens. In the current study, 365 children from low-income families (58% Caucasian, 17% Hispanic, 25% African American; 54% girls) were followed from preschool through seventh grade. Regression analyses predicted teacher and parent ratings of seventh-grade student aggression with school levels of poverty (percentage of students receiving free or reduced lunch) and academic achievement (percentage of students scoring below the basic proficiency level on state achievement testing) experienced during elementary school and middle school, controlling for student baseline aggression and family demographics. Results revealed significant effects of elementary- and middle-school school-level context on student aggression in seventh grade, with middle-school school achievement levels making unique contributions across school and home settings (teacher and parent raters). Implications, limitations, and future directions of these findings are discussed.
