The aim of this study was to determine if adolescents' scores on a 2-item underage alcohol use screener predict risky consequences of past-year alcohol use and other health risk behaviors in a nonclinical, school-based sample of adolescents. A predominantly minority sample of 756 middle and high school students completed in-school tablet-based…

This study identified classes of developmental trajectories of physical dating violence victimization from grades 8 to 12 and examined theoretically-based risk factors that distinguished among trajectory classes. Data were from a multi-wave longitudinal study spanning 8th through 12th grade (n = 2,566; 51.9 % female). Growth mixture models were…

The effect of early adolescent alcohol use on antisocial behavior was examined at 1- and 2-year follow-up in Washington State, United States, and Victoria, Australia. Each state used the same methods to survey statewide representative samples of students ("N" = 1,858, 52% female) in 2002 (Grade 7 [G7]), 2003 (Grade 8 [G8]), and 2004…

The identification of developmentally specific windows at which key predictors of adolescent substance use are most influential is a crucial task for informing the design of appropriately targeted substance use prevention and intervention programs. The current study examined effects of conduct problems and depressive symptomatology on changes in…

Prospective longitudinal data from over 14,000 youth residing in 28 communities in the rural United States were analyzed to examine the emergence of mixed-sex friendship groups in early adolescence. Youth were surveyed on 5 occasions between fall of 6th grade and spring of 9th grade. At each assessment, youth reported the names of up to 7…

This study explores the trajectory of suicidal ideation in childhood and adolescence and identifies its strong predictors. Secondary data obtained from two nationally representative cohorts of South Korean youth were longitudinally analyzed using frequencies, percentages, and discrete time survival analysis. This study revealed an increase in the…

This study seeks to provide a greater understanding of the factors that determine the perceived availability of alcohol and its role in predicting adolescents' alcohol use. Participants were 151,703 7th-12th grade students (50% female) from a sample of 219 rural communities across the United States, with oversampling for predominantly…

Parental knowledge is defined as parental awareness and information about a child's activities, whereabouts, and associations that is obtained through parental monitoring, parental solicitation, or self-disclosure. Increased parental knowledge is generally associated with lower adolescent substance use; however, the influence of various contextual…

This study investigated cultural identity and peer influence on tobacco, alcohol, and cannabis use in a culturally diverse sample of Northern Australian adolescents. Middle school students (n = 274) completed the Multigroup Ethnic Identity Measure (MEIM) and measures of their own and perceived friends' substance use. Higher scores on the full…

For the four leading causes of death in the United States (heart disease, cancer, stroke and chronic respiratory disease), tobacco use is a common risk factor. Tobacco use is responsible for almost 450,000 deaths per year and impacts the health of every member of our society. Tobacco is a gateway drug for substance abuse. That role is critical to…

Network position ("isolate," "member," "liaison"), peer-group substance use, and their interaction were examined as predictors of cigarette, alcohol, and marijuana use in a sample of 163 urban sixth, seventh, and eighth graders. Two measures of peer substance use were compared: one based on social network analysis…

This study examined the longitudinal effects of five family factors (familism, parent derogation, parent-child communication, family alcohol problems, and family drug problems) on intensity of alcohol use among a sample of 451 African American and White non-Hispanic males from early to mid-adolescence (sixth through eighth grades). Results…

Monitoring the Future (MTF) is a long-term study of American adolescents, college students, and adults through age 50. It has been conducted annually by the University of Michigan's Institute for Social Research since its inception in 1975. It is supported under a series of investigator-initiated, competing research grants from the National…

The current study explores whether theorized risk factors in Western countries can be used to predict school violence perpetration in an Asian cultural context. The study examines the associations between risk factors and school violence perpetration in Taiwan. Data were obtained from a nationally representative sample of 14,022 students from…

The Monitoring the Future (MTF) study is an ongoing series of national surveys of American adolescents and adults that has provided the nation with a vital window into the important, but largely hidden, problem behaviors of illegal drug use, alcohol use, tobacco use, anabolic steroid use, and psychotherapeutic drug use. For more than a third of…
