Adolescent substance use is a top national public health concern with approximately 50% of youth having tried an illicit substance by the end of high school. The transition to high school is a critical point for substance use initiation. Despite this fact, there is relatively limited research looking at factors that can protect students from…

Background: While a theoretical association between religiosity and substance use is anticipated, there is limited empirical evidence testing this theoretical proposition among Nordic adolescents. It was anticipated that studying these substance-use correlates from a criminological perspective by employing a large sample of students could provide…

Reports of deportation can create a state of chronic fear in children living in mixed-status immigrant families over their own or a loved one's potential deportation. One indicator of health disparities among youth is elevated rates of alcohol, tobacco, and other drug use (ATOD). Yet little is known about the effects of fear of deportation (FOD)…

Polysubstance use is related to elevated risk for adverse outcomes but remains understudied among early adolescents. This study focused on a cross-sectional (N = 1568) primarily Black (79%) sample of eighth grade students living in urban communities (Mean age = 13.8, SD = 0.68) to identify subgroups based on adolescents' reports of lifetime and…

Background: Previous studies demonstrate a relationship between body dissatisfaction and substance use and suicidal ideation among older adolescent girls and young women while less documentation exists for early adolescence. This study explored the relationship between reported weight loss attempts and substance use history and suicidal thoughts…

Substance use in adolescence is a significant public health issue, particularly in early-to-mid adolescence, which represents a window of risk in the etiology of substance abuse and dependence. Substance use during this development period often results from affiliation with deviant peers, who model, facilitate, and reinforce use. Existing…

This study examined the program effectiveness of Health Rocks!, a youth substance use prevention program. Merging data from 128,544 youth participants in 21 states between 2009 and 2021, this study compared self-reported levels of knowledge, skills, and internal and external assets before and after the program. Youth reported significant increases…

Rural adolescents are at a greater risk for substance abuse and other mental health challenges. There is a need for enhanced evidence-based prevention efforts. This case study evaluated both remote and in-person instruction of "Second Step®", a social-emotional learning (SEL) curriculum aimed to improve school-based prevention efforts.…

Purpose: This study explored differences between lesbian, gay, and bisexual (LGB)-housed and homeless students regarding substance use patterns on and off school grounds and the unique contribution of homelessness to substance use in school. Methods: Data were from the 2013-2015 California Healthy Kids Survey, a statewide survey of school…

Background and Purpose: Sleep is an important determinant of health in adolescence, but many adolescents around the world are sleep-deprived. Compared to children and adults, getting enough sleep is especially challenging for adolescents due to the natural alteration of circadian rhythms that govern sleep-wake cycles. The delayed circadian rhythm…

An emerging body of research documents a relationship between sleep quantity and delinquency during adolescence. Absent from this line of research, however, is an evaluation of whether the associations between sleep duration and different forms of delinquency vary across periods of adolescence and sex. The current study aimed to address this gap…

Iceland has witnessed a dramatic decline in adolescent substance use that may be partly the result of efforts related to the Icelandic prevention model (IPM). We sought to test risk and protective factor assumptions of the IPM using a prospective cohort study with 12 months separating baseline from follow-up. Participants were students in grades 8…

Across the country, many schools have adopted restorative practices in an effort to improve school climate and student outcomes while reducing exclusionary discipline. Restorative practices are designed to proactively build community, improve relationships, and help students amend harm when conflict occurs. Using 6 years of student survey data and…

As of 2024-25, Roswell Independent School District has four community schools, including Sierra Middle School--entering its fifth year of implementation--and University High School--an alternative school entering its third year of implementation. Sierra and University High have each created a nourishing school climate and culture by providing…

As evidence-based interventions (EBIs) become more widely disseminated, fidelity of implementation (FOI) often wanes. This study explores the association between FOI and malleable variables within classrooms that could be targeted to optimize resources without compromising FOI as school-based EBIs are disseminated across real-world settings. We…
