Adolescents attending Grade 7-10 (N = 329), answered questionnaires regarding their perceived social support (from parents, teachers, classmates, and…

Antisocial peer behavior and low parental knowledge of adolescents' activities are key interpersonal risk factors for adolescent substance use. However, how the magnitude of associations between these risk factors and substance use may vary across adolescence remains less well understood. The present study examined the age-varying associations of…

Monitoring the Future (MTF) is designed to give such attention to substance use among the nation's youth and adults. It is an investigator-initiated study that originated with, and is conducted by, a team of research professors at the University of Michigan's Institute for Social Research. Since its onset in 1975, MTF has been funded continuously…

The 2020 survey, reported…

Parents impact adolescent substance abuse, but sex-specific influences are not well-understood. This study examined parental influences on adolescent drinking behavior in a sample of ninth-grade students (N = 473). Hierarchical regression analyses indicated parental monitoring, disapproval of teen alcohol use, and quality of parent-teen general…

The movement from middle school to high school is a normative transition that is typically associated with increased stress and opportunity in social and academic domains. Theoretically, this transition may reflect a turning point in terms of initiating or sharply increasing heavy alcohol use, a notion that has received little attention in the…

We examined whether parental monitoring at baseline predicted subsequent substance use in a high-risk youth population. Students in 14 alternative high schools in Washington State completed self-report surveys at three time points over the course of 2 years. Primary analyses included 1,423 students aged 14-20 who lived with at least one parent or…

This study examined the link between victimization and sexual orientation and how this link contributes to social-emotional health, extending to school-related outcomes among adolescents. Of additional interest was whether having caring adult support was a protective factor in reducing the risk for high levels of distress or enhancing positive…

This study used a representative metropolitan sample to make longitudinal comparisons of college-bound and non-college-bound youth on incidents and predictors of heavy drinking. Respondents in the six-wave study were ages 13-16 at wave 1 and 18-21 at wave 6 (n's ranged from roughly 425-500 for different analyses). College/non-college comparisons…

Background: Alcohol, tobacco, marijuana use, and sexual behaviors are consistently reported by high school students in the United States and can contribute to reduced quality of life. Empirical research finds that many assets may act as a protective factor for adolescent risk behaviors. As such, the purpose of this study was to examine the…

Objective: The authors examined the sociodemographics and psychobehavioral characteristics of undergraduate US college students who abstain from alcohol. Participants: The respondents were 5,210 undergraduates from 32 colleges and universities. Methods: A survey was mailed to 300 randomly selected students per institution (spring 2000 or 2001).…

The Monitoring the Future (MTF) study involves 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…
