Background: Although there are concerns regarding the use of restrictive housing with detained youth, little research has examined factors that contribute to youth risk for restrictive housing. Objective: The current study examined whether perceived containment and contextual factors (i.e., peer delinquency, neighborhood problems, stressful life…

This study examined the role that peer groups play in shaping students' academic re-engagement across their first year in middle school and whether influences are stronger from peers with whom students remained affiliated over time. Data were collected on an entire cohort of 366 sixth graders (48% female) in a small town. Students reported on…

The world of education is filled with policies which aim to improve student outcomes. While there are many factors which may potentially contribute to the academic success of a student, there are similarly a wide variety of measures which can be used to determine student success. This dissertation examines some specific policies and environments…

In evaluating the deleterious effects of missing in-school time, research has almost exclusively focused on absences, and almost no attention has been paid to tardiness. Hence, this study contributes a new dimension to the field by examining the effects of student tardiness on academic achievement. Employing an empirical model on a large-scale,…

We develop a Roy model of social interactions in which individuals sort into peer groups based on comparative advantage. Two key results emerge: First, when comparative advantage is the guiding principle of peer group organization, the effect of moving a student into an environment with higher-achieving peers depends on where in the ability…

Classmates' academic skill level (peer effects) is emerging as an important predictor of individual student achievement, particularly in the early grades. However, less is known about the influence of peer effects with regard to classmates' self-regulation skills and whether they are associated with students' academic gains. Examining this is the…

In this article we examine how social capital affects the creation of human capital. Specifically, we study how college students' peers affect academic performance. Building on existing research, we consider the different types of peers in the academic context and the various mechanisms through which peers affect performance. We test our model…

Studies with adults of social dominance orientation (SDO), a preference for inequality among social groups, have found correlations with various prejudices and support for discriminatory practices. This study explores the construct among adolescents at an age when they are beginning to recognize the social groups in their environment, particularly…

This study examined whether peer groups can indirectly affect children's academic development in sixth grade (ages 11 to 13) by influencing their engagement in the classroom. From the entire cohort of 366 sixth graders in a town, 87% provided information at the beginning and end of the school year. Peer groups were assessed using Socio-Cognitive…

The present study analyzed the long-term effects of perceived friend use and perceived peer use on adolescents' own cigarette, alcohol and marijuana use as a series of parallel growth curves that were estimated in two developmental pieces, representing middle and high school (N = 1,040). Data were drawn from a large drug abuse prevention trial,…

School, parental and peer group effects have been identified as being influential in shaping the decision of students to participate in post-compulsory education, but the analysis of each effect separately is rare. Using a random effects logistic regression approach, estimates of the importance of school, parental and peer group effects on student…

The current investigation examined how homophobic and aggressive social climates of adolescent peer groups accounted for students' use of homophobic epithets and engagement in homophobic banter using multilevel modeling. Results indicated that aggressive peer group social climates accounted for increased use of epithets, over and above…

The broader context of relational aggression in adolescent romantic relationships was assessed by considering the ways such aggression emerged from prior experiences of peer pressure and was linked to concurrent difficulties in psychosocial functioning. Longitudinal, multi-reporter data were obtained from 97 adolescents and their best friends at…

This study examined the effects of peer groups on changes in academic engagement in 11- to 13-year-old children. From the entire cohort of 366 sixth graders in a town, 87% participated at the beginning and end of the school year. Peer groups were assessed using socio-cognitive mapping; as an indicator of motivation, teachers reported on students'…

The fact that crime and victimization share similar correlates suggests that family and peer contexts are potentially useful for explaining individual differences in violent victimization. In this research, we used routine activities and lifestyles frameworks to reveal how strong bonds of family attachment can promote more effective guardianship…
