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, teams of research professors at the University of Michigan's Institute for Social Research. MTF contains ongoing national surveys of both adolescents…

Deviant behavior has become a daunting problem lately. More pupils are displaying abnormal behavior and thus destabilizing learning processes within school settings. It is a well-known fact that teenagers usually learn how to adapt to society and that aberrant behavior may lead to problems with conformity to societal values. Although the main…

Adolescent risk-taking can potentially result in serious individual and societal consequences. Previous research demonstrates that emotional and behavioral problems, particularly externalizing behaviors, are significantly associated with an array of risky behaviors such as substance use, sexual behavior, injury, and violence. However, the…

Mounting evidence indicates that students of color are more likely than their white peers to receive exclusionary discipline (out-of-school suspensions and expulsions), but alleviating these disparities requires an understanding of what drives them. In this study, we use seven years of student- and infraction-level data from every public school in…

Family structure is associated with a range of adolescent risk behaviours, with those living in both parent families generally faring best. This study describes the association between family structure and adolescent risk behaviours and assesses the role of the family meal. Data from the 2006 Health Behaviour in School-Aged Children survey were…

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…

Communities across the country have a vested interest in making sure that young people develop into healthy productive citizens and avoid behaviors that can jeopardize their own health and well-being and threaten the well-being of their families and neighborhoods as well. Substance abuse and delinquency are prime examples of behaviors that get in…

Evidence for shared heritable influences across domains of substance use suggests that some genetic variants influence broad risk for externalizing behaviors. Theories of externalizing psychopathology also suggest that genetic liability for substance use manifests as temperamental risk factors, particularly those related to behavioral…

Students who engage in high-risk behaviors, including early initiation of sexual intercourse, alcohol use, marijuana use, tobacco use, and externalizing behavior are vulnerable to a broad range of adverse outcomes as adults. Latent class analysis was used to determine whether varying patterns of risk behavior existed for 212 urban African-American…

Each year since 1997, the Federal Interagency Forum on Child and Family Statistics has published a report on the well-being of children and families. The "America's Children" series provides accessible compendiums of indicators drawn across topics from the most reliable official statistics; it is designed to complement other more…

Initiation of drug use and other risky behavior in preadolescence is associated with poor developmental outcomes. In this research, we examine models that ascribe the trajectory to (a) weak executive cognitive function (ECF), (b) early manifestation of externalizing problems, or (c) heightened levels of trait impulsivity. We test the explanatory…

Research has begun to show associations between adolescents' mealtime practices and their engagement in problem behaviors. Few studies have addressed this longitudinally and/or examined lunchtime practices during the school day. This study tests for associations between urban multiethnic middle school students' (N = 1498) lunchtime practices in…

The purpose of the research was quadrupled. It investigated the prevalence of anti-social behaviours in campuses of Nigerian universities. Several student fitness aspirants and recreationists perceived examination malpractices (85%), stealing (83%), armed robbery (81%), prostitution (82%), drunkenness (80%), smoking (79%), hard drug consumption…

Background: Health risk behaviors like substance use (alcohol, tobacco, soft/hard drugs) and risky sexual behavior become more prevalent in adolescence. Children with behavior problems are thought to be prone to engage in health risk behaviors later in life. It is, however, unclear which problems within the externalizing spectrum account for these…

Researchers have found mixed support for documenting whether work is protective or harmful during adolescence. This study examined the association between work and problem behaviors among African American youth (N = 592; 53% female; M = 14.8 years, SD = 0.60) followed from mid-adolescence to young adulthood over eight Waves (90% response rate over…
