This study evaluated the psychometric properties of the Hope-Action Inventory (HAI) scores with a problematic substance use population (N = 783). The hierarchical seven-factor structure of the HAI fit the data well. Further, the HAI scores had satisfactory internal consistency reliability and good convergent evidence for validity.

The current study assessed whether risk factors associated with vaping were distinct from risk factors associated with other substance use (e.g., alcohol, cannabis) during adolescence. Participants (N = 848, ages 10-16 years) completed a self-report survey to assess frequency and age of onset of substance use, risk perceptions of use, risk factors…

Objective: To compare the prevalence and trajectories of risky health behaviors in sexual minority (SM; lesbian/gay/bisexual/questioning/asexual) versus heterosexual undergraduates across their first year of post-secondary. Participants: First-year undergraduates (N = 704, M[subscript age] = 17.97 years, 24% SM) from a midsized Canadian…

This study examined how schools prioritize ten key health concerns among their student populations over time and whether schools' prioritization of alcohol and other drug use (AODU) corresponds to students' substance use behaviours and cannabis legalization as a major policy change. Data were collected from a sample of secondary schools in…

The risk of delinquent to antisocial behaviors among youth (teenagers) seem to be more prevalent in group homes than other foster homes. The aim of this study was to examine the association between negative peer influence and youth antisocial behaviors in group homes. Participants were 875 youth aged 10 to 17 at baseline (2010-2011). Logistic…

Background: Youth psychosocial and school adjustment results from complex developmental transactions between their individual characteristics and diverse environmental influences, which appear as risk or protective factors throughout one's development. Objective: From an ecosystemic and developmental perspective, this study aims to: (1) identify…

Alcohol use is prevalent among post-secondary students and negatively impacts their academic achievement. Socially constructed gender-based perceptions can promote alcohol misuse on campus.

Aims: To estimate effects of brief substance use interventions delivered in general medical settings. Methods: A systematic review and meta-analysis of randomized trials conducted since 1990 of brief substance use interventions in patients of any age or severity level recruited in general medical settings. Primary outcomes were any measure of…

The dysregulation profile (DP) in youth is characterized by severe emotional, cognitive, and behavioral dysregulation and is associated with an increased risk for psychiatric disorders. Adolescent self-regulation has important implications for adulthood outcomes, yet this association is understudied in the context of the DP in emerging adults.…

The goal of the present study was to replicate Burt et al. (2009) and Hou et al. (2013) findings by determining the contribution of peers' deviance to changes in participants' (monozygotic [MZ] twins') self-reported delinquency from mid- to late adolescence while controlling for possible gene-environment correlations (rGE) through the use of the…

Adolescents are likely to experiment with risky behaviors, such as substance use, which can have implications lasting throughout their lives. Private schools, while not immune to substance use, tend to report lower levels of substance use among their students when compared to the adolescent population in general. This quantitative study focuses on…
