In 2006 California implemented a unique firearm monitoring program, the Armed and Prohibited Persons System (APPS), to address gun violence in the state. The APPS program first identifies those firearm owners who be-come prohibited from owning one due to federal or state law,…

The goal of the current pilot study was to examine the effects of bystander intervention training on a sample of 27 high school students who were selected by their peers as opinion leaders. Measures of bystander intervention knowledge, attitudes, and behaviors were included in the within-subjects design. Sixteen of the students also participated…

We describe a holistic approach to promoting school safety that merges an emphasis on student voice with staff training in restorative practices. We first describe current approaches to keeping schools safe based on the existing research literature. Given that most of these approaches rely on access to credible information about potential threats…

Teen dating violence victimization is associated with a host of adverse mental and physical health problems. A number of bystander-focused interventions have been developed to mitigate the occurrence of abuse but with varying effectiveness. There remains a need to understand more about bystander behaviors used by adolescents to ensure that…

As an example of how historical events may influence the findings and interpretations of a randomized trial, we use a school-based evaluation of a classroom management program that was conducted in a nearby district before and after the shooting of Michael Brown in Ferguson, Missouri (N = 102 teachers and 1,450 students). The findings suggest that…

Early life adversity influences the diurnal cortisol rhythm, yet the relative influence of different characteristics of adversity remains unknown. In this study, we examine how developmental timing (childhood vs. adolescence), severity (major vs. minor), and domain of early life adversity relate to diurnal cortisol rhythms in late adolescence. We…

Drawing upon an ongoing school mental health survey being conducted in California, this article examines associations between high school students' mental wellness, including covitality (as measured with the Social Emotional Health Survey--Secondary), and school safety perceptions and experiences. Student self-reports reveal a strong positive…

Few published studies have examined the interaction between community violence exposure, academic engagement, and parental involvement, despite theory suggesting that these three domains of development are interrelated during adolescence. This study had two related objectives: (a) to assess the temporal ordering of the relation between community…

Does social influence exerted through role modeling of collective action impact social change in contexts that are not conducive to collective action, such as long-lasting violent conflicts?

School closures due to teacher strikes or political unrest in low-resource contexts can adversely affect children's educational outcomes and career opportunities.

Exposure to violence, both political and community violence, has detrimental implications for…

A wealth of past research has examined the relationship between low physiological arousal and violence or antisocial behavior. Relatively little research; however, has examined the relationship between low physiological arousal and psychopathic traits, with even less having been conducted with juveniles. The current study attempts to fill this gap…

Positioning our analyses within two theoretical frameworks, system justification (SJ) theory and critical consciousness (CC), we examine relationships between social class and endorsement of SJ and CC beliefs and behaviors within a sample of low-income, Latinx and Black youth living in Chicago. We operationalize social class using five indicators:…

Given the rise in dual career and single-parent families, and the need for monitoring and supervision during out-of-school time, afterschool settings are becoming important contexts for the prevention of problem behaviors and the promotion of the positive development of youth. Research indicates that high-quality afterschool programs can have…

Critical consciousness (CC) has emerged as a framework for understanding how low-income and racial/ethnic minority youth recognize, interpret, and work to change the experiences and systems of oppression that they face in their daily lives. Despite this, relatively little is known about how youths' experiences with economic hardship and structural…
