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…

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…

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…

An earlier trial of a school-based, preventative intervention, HealthWise South Africa, demonstrated some efficacy in preventing adolescent drinking and smoking in the Western Cape, South Africa. This was followed by the current implementation trial, which examined how implementation support conditions influenced adolescent drinking and smoking…

This paper examines the extent to which transgender students' experiences with school-based victimization and school protective factors contribute to or reduce substance use. We conducted secondary analyses of school-based victimization, school protective factors, and substance use of a subsample of transgender students from the 2013-2015…

The consequences of adolescent drug and alcohol use may be serious and far-reaching, forecasting problematic use or addictive behaviors into adulthood. School counselors are particularly well suited to understand the needs of the school community and to seamlessly deliver sustainable substance use prevention. This pilot study with 46 ninth-grade…

In recent years, peer education programs (PEPs) have put this effect to use in a positive way by providing peers that constitute positive role models for each other. Accordingly, this study was carried out to determine the effect of a PEP on the basic knowledge of adolescents about addiction and on the level of self-efficacy that is needed to…

The tables in this report provide national-level estimates of the extent to which students ages 12-18 enrolled in grades 6-12 experience bullying during school. The tables show how bullying victimization varies by student and school characteristics such as sex, race/ethnicity, grade, household income, region, school locale, school enrollment size,…

Community violence exposure is associated with externalizing problems in adolescents, yet little research has examined the moderating role of coping in these relationships. Eighty-four low-income, urban adolescents (M[subscript age] = 13.36, 50% male, 95% African American) participated in two waves of a longitudinal study a year and a half apart.…

Ethnic identity is a consistent predictor of positive youth adjustment, whereas discrimination has been associated with negative outcomes among Latino/a youth. Scholars have proposed associations between ethnic identity and discrimination; however, directionality of effects remains unclear. Addressing this gap, the current study examined the…

This study examines developmental change across adolescence in the similarity of friends versus nonfriends. This differential in similarity is a key aspect of the organization of the peer context of development: The stronger the correlation between friends for an attribute, the more the attribute delineates clustering and divisions of friendships.…

Under the integrated model of General Strain Theory (GST), the present study sought to examine whether delinquent peer association, social control, and negative emotion moderated the relations of distinctive cyberbullying roles with delinquency, as well as whether the moderating effects varied by gender among a nationally representative sample of…

Bullying and mental health problems are pressing concerns for adolescents. Given their burden, we need to find efficacious ways to prevent these experiences. However, existing prevention programs tend to be single-issue and may not focus on the universal capacities required to reduce these problems among youth. To this end, we evaluated the…

Face-to-face and cyberbullying are associated with adverse behavioral or health problems. However, little is known about the association between multiple types of bullying and substance use. The current cross-sectional study compares the association among face-to-face and cyberbullying (bully-only, victim-only, bully/victim, non-involved) and…
