Disruption of Transitions in High-Risk Substance Use from Adolescence to Young Adulthood - School, Employment, and Romantic Relationship Factors

This study adds to the literature by examining the extent to which school, employment, and romantic relationship factors can disrupt problematic patterns of substance use (i.e. polysubstance use) in a sample of youth followed a decade from adolescence (ages 12-18) to young adulthood (ages 22-29). Specifically, we examine the extent to which school, employment, and romantic relationship factors can disrupt transitions among high-risk use classes at various developmental time points in the transition from adolescence to young adulthood.

Family Violence, Sibling, and Peer Aggression During Adolescence - Associations with Behavioral Health Outcomese

The current study had two phases. Phase 1 assessed heterogeneity in peer and sibling aggression. Specifically, we tested the theory of intergenerational transmission of violence, by using early adolescent exposure to family violence as predictors of emergent profiles of peer and sibling aggression and how these profiles differ by demographics (i.e., sex, race/ethnicity). In Phase 2, we included exposure to family violence in a mixture model with peer and sibling aggression. This phase allowed us to examine family violence exposure and engagement in peer and sibling aggression in tandem.

Examining Classes of Bully Perpetration among Latinx High School Students and Associations with Substance Use and Mental Health

The aim of this study is to examine the heterogeneity among bullying behaviors in a sample of Latinx adolescence and associations with mental health issues and substance use perceptions.

Adolescent Patterns of Peer Victimization - Concurrent and Longitudinal Health Correlates

We examine how heterogeneity in adolescent experiences of peer victimization impact health in adolescence and young adulthood. We include multiple indicators of mental health - internalizing symptoms (i.e., depressive and anxiety symptoms), externalizing symptoms (i.e., attention deficit hyperactivity disorder (ADHD) symptoms, oppositional defiant disorder (ODD) symptoms, and conduct problems), and substance use (i.e., smoking, heavy drinking, marijuana and illicit drug use). We also use multiple measures of physical health - subjective health (i.e., physical symptoms and physical self-concept), health-promoting behaviors (i.e., physical activity, healthy eating practices, and sleep duration and problems), and cardiometabolic risks (i.e., BMI waist circumference, and hypertension). In examining young adult health, we directly control for earlier (i.e., baseline) symptoms in order account for stability in health over time.

Examining the Pathways Between Bully Victimization, Depression, Academic Achievement, and Problematic Drinking in Adolescence

In Hong et al.’s (2014) conceptual framework, the author’s proposed important mechanisms and paths that may contribute to the association between bully victimization and substance use among adolescents. Specifically, we extend this framework and prior research by examining longitudinal within-person bidirectional relationships between bully victimization, depression, academic achievement, and problematic alcohol use from three theoretical frameworks - interpersonal risk model, symptom driven model, and a transactional model.

Social Ecological Determinants of Substance Use Treatment Entry Among Serious Juvenile Offenders From Adolescence Through Emering Adulthood

Applying a social–ecological framework, this study aims to fill a gap in the literature by investigating factors in various domains (individual, familial, peer, and neighborhood) separately and simultaneously to determine risk and protective factors for treatment entry among serious juvenile offenders over the course of 7 years.

Examining Within-Person and Between-Person Effects of Victimization and Social Risk on Cannabis Use Among Emerging Adults in Substance-Use Treatment

The current study used a large sample of EAs in outpatient substance-use treatment and investigated both within-person (time-varying) and betweenperson (time-invariant) relations of victimization and peer risk on cannabis use over a 12-month period.

The Longitudinal Associations Between Substance Use, Crime, and Social Risk Among Emerging Adults - A Longitudinal Within- and Between-Person Latent Variables Analysis

The current study examined the reciprocal relationships between crime, substance use, and social risk among emerging adults (aged 18–25 years) in substance use treatment.
