Polysubstance use is associated with myriad short- and long-term health outcomes. Although prior research has documented differences in polysubstance use between lesbian, gay, bisexual, transgender, queer/questioning, and other sexual and gender minoritized (LGBTQ +) youth and their heterosexual/cisgender counterparts, as well as between subgroups…

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…

The current study sought to better understand how leisure boredom is associated with alcohol use and how peer factors moderated the relationship between state and trait leisure boredom and past month alcohol use. The 2004 to 2008 multi-cohort study sample included 3,837 high school students (50% female; 91% mixed race; M[subscript age] = 14 years;…

Parent-child similarity is a function of genetic and environmental transmission. In addition, genetic effects not transmitted to offspring may drive parental behavior, thereby affecting the rearing environment of the child. Measuring genetic proclivity directly, through polygenic risk scores (PRSs), provides a way to test for the effect of…

Background: People with intellectual disability may be at elevated risk of adverse consequences of substance use. This study outlines the prevalence of, and factors associated with, substance use in young people with and without intellectual disability. Method: Secondary analysis was undertaken of the Next Steps annual panel study, which follows a…

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…

Adolescents commonly engage in substance use and sexual behaviors which pose risks for their health. Secondary data analysis of two school-based surveys explored the clustering of lifetime use of cigarettes, alcohol, cannabis, and engagement in sexual intercourse among 2,489 adolescents in Scotland and 1,405 adolescents in Northern Ireland. All…

Adolescents often practice unhealthy behaviors to lose weight or keep from gaining weight. Centers for Disease Control and Prevention has conducted biennial Youth Risk Behavior Survey (YRBS) of various health risk behaviors since 1991 using U.S. representative samples of high school students and is therefore best for us to identify risk/preventive…

The purpose of the present study is to determine if high school students' character strengths composed of twenty-four different strengths, virtues including six dimensions and demographic characteristics predict risky behaviors. The participants of the study were 380 students aged between 14-19 years and enrolled in general high schools. The data…

Background: We examined the longitudinal trajectory of substance use (binge drinking, marijuana use, and cocaine use) in relation to self-esteem from adolescence to young adulthood. Methods: Generalized estimating equation models were fit using SAS to investigate changes in the relation between self-esteem and each substance use (binge drinking,…

Adolescents exposed to adverse childhood experiences (ACEs) are at increased risk for substance use. Factors that reduce likelihood of adolescent substance use are an important area of research and intervention. The present study aimed to understand the cumulative impact of household dysfunction ACEs on adolescent alcohol and marijuana use and to…

Aims: In this study we look at (1) changes in parenting practices related to adolescents' alcohol use in Finland from 2006 to 2012 and (2) whether parents' own drinking behaviour is related to the parenting practices. Methods: Two surveys of parents with children were conducted in 2006 (n = 2864) and 2012 (n = 2965). The data were analysed using…

This study built on research on sibling influences to assess potential bidirectional effects of older and younger siblings' risky behaviors on one another's risky behaviors; our longitudinal design allowed us to test these effects when siblings were at about the same chronological age, at different points in time. We also tested whether the…

Previous methodological approaches have not been flexible enough to model the heterogeneity of depressive symptoms or to identify variations between prototypical trajectories conditional on risk and protective factors. The current study examined latent class trajectories of depressive symptoms using data from 3,819 respondents of the Adolescent…

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…
