Methods: This was a quasi-experimental single-group pre-post study without a control group in a secondary education setting (n = 151; ages 15-17). Intervention Three standardized 1 h classroom sessions de…
Open article record in new tab ↗BACKGROUND: Adolescent substance abuse is a growing public health concern associated with poor mental health, unsafe sexual behaviour, violence, school dropout, and psychosocial dysfunction. In rural South Africa, peer influence, cultural practices, poverty, and inadequate psychosocial support may increase learners' vulnerability to substance use. However, limited qualitative evidence exists on how these factors i…
Open article record in new tab ↗Background/objectives Cannabis use has a particularly high prevalence in individuals with psychotic disorders. Although cannabis use is generally associated with cognitive impairments in the general population, its impact on cognition in psychosis remains controversial. This study aimed to investigate the association between cannabis use and cognitive performance in a cohort of individuals affected by psychotic di…
Open article record in new tab ↗AbstractBackgroundPrevious studies demonstrated the effectiveness of SmartCoach, a mobile phone–based life-skills training program for addiction prevention among adolescents. However, socially stratifying factors, such as educational level or migration background, were associated with lower program engagement and participation. To address these disparities, we optimized and tailored program elements, particularly…
Introduction Recent studies show that young females now report higher e-cigarette use than males, reversing prior trends. While sex differences in use are documented, little is known about underlying risk profiles. This study applied a machine learning (ML) approach to identify and compare predictors of adolescent e-cigarette use by sex. Methods We analyzed cross-sectional data from 1829 9th graders in Southern Ca…
Open article record in new tab ↗BackgroundOne year after the partial legalisation of cannabis, the effects on cannabis use among young people in Germany were investigated.MethodsBased on twelve representative studies from 2008 to 2025, changes in the 12-month prevalence of cannabis use among 12- to 17-year-old adolescents and 18- to 25-year-old young adults were presented, and trends over time were estimated.ResultsAmong female and male adolesce…
Open article record in new tab ↗Abstract Background: Adverse Childhood experiences (ACEs) disproportionately affect minoritized and low-income youth. Those with four or more ACEs are particularly vulnerable to chronic, unpredictable stress, which shapes their stress perception and response. Higher exposure to ACEs is associated with an increased risk of self-dysregulation, early initiation of alcohol and substance use, and cardiometabolic issues…
BackgroundAdolescents often navigate complex psychological, behavioral, and identity-related challenges, yet many do not seek the mental health support they need. Sexual minority youth face additional identity-based barriers that further hinder access to care.MethodA sample of 1,129 Israeli adolescents aged 16–18 (M = 17.42, SD = 1.03), including 30% who identified as sexual minorities, completed measures of menta…
Open article record in new tab ↗Introduction Bullying remains a major public health concern among adolescents and is associated with adverse mental health and behavioral outcomes. Evidence from low- and middle-income countries, including Ecuador, remains limited. Methods We conducted a cross-sectional study using data from the Ecuadorian version of the Youth Risk Behavior Surveillance System (YRBSS). Associations between school bullying, cyberbu…
Open article record in new tab ↗Aims To test whether the total consumption model and its extension, the theory of collectivity, apply to adolescent cannabis use. We estimated: (1) whether the distribution of cannabis use frequency was stable over time; (2) whether changes in average cannabis use were mirrored across consumption quantiles; and (3) whether higher average use corresponds with a higher prevalence of high-frequency users. Design Repe…
Open article record in new tab ↗IntroductionDespite evidence of the impact on academic performance of cannabis use disorder (CUD) there is little information about what happens in those cases of dual diagnosis, when CUD occurs along with other mental health disorders (DD).MethodsParticipants in this study (N = 300) were recruited from patients seeking treatment for CUD at an adolescent addictive behaviors unit. A multivariate logistic regression…
Open article record in new tab ↗Substance use and high-risk sexual behaviors remain pressing public health challenges among U.S. adolescents, with tobacco, alcohol, and marijuana being the most used substances. While previous research has shown an association between substance use and risky sexual behavior, there is limited data on how these associations vary based on demographic modifiers such as race, sex, and sexual identity among sexually ac…
Open article record in new tab ↗Background and aims Sexual minority youth report significantly higher rates of substance use than heterosexual youth, yet a comprehensive and systematic evaluation and synthesis of the magnitude of this inequity has not been conducted. The purpose of this study was to conduct a meta-analysis to assess the magnitude of overall inequities in substance use between sexual minority and heterosexual youth and examine de…
Open article record in new tab ↗Background Stigma experienced by individuals with cannabis use disorder (CUD) has been identified as a significant impediment to their engagement with treatment programs. Therefore, this study aims to investigate the effect of sociodemographic factors and familiarity with cannabis on stigmatizing attributions towards adolescent and adult case vignettes of people affected by CUD. Method A quota sampling web survey…
Open article record in new tab ↗Adolescent substance use imposes lasting costs on education, mental health, and lifetime earnings, with early initiation strongly predicting adult dependence. Despite legal prohibition, approximately 21% of U.S. high school students report current alcohol use, 18% report current nicotine vaping, and 16% report current cannabis use. Social media plausibly contributes to these patterns, yet prior studies rely on bro…
Open article record in new tab ↗BackgroundGuidelines on pre-pregnancy counselling are primarily clinical, and although recommendations and policy documents on preconception care exist in Australia, they place little or no emphasis on preconception health of adolescents and young adults. ObjectiveTo identify and prioritise unanswered questions and evidence uncertainties concerning preconception health needs of adolescents and young adults residin…
Open article record in new tab ↗Tuberculosis (TB) remains a major global health challenge, particularly in low- and middle-income countries such as Mozambique. To address this burden, promising new preventive TB vaccines targeting adolescents and adults are currently in phase III efficacy trials. This study aimed to assess stakeholders perspectives on priority high-risk groups, the challenges in reaching them, and potential strategies for delive…
Open article record in new tab ↗BackgroundAdolescent sexual and reproductive health (ASRH) remains a critical public health priority in Ethiopia, where adolescents face persistent barriers to accessing responsive and high-quality sexual and reproductive health (SRH) services. Conventional top-down interventions often fail to address adolescents lived experiences and local contexts. Human-centered design (HCD) offers a participatory and context-s…
The Satisfaction with Life Scale (SWLS) has been extensively validated using Classical Test Theory, mostly relying on factor analytic methods among adult samples. The current study used Item Response Theory to validate SWLS among a sample of early adolescents in California and examine associations between SWLS and tobacco and cannabis use. Data were collected from ninth-grade students (N = 2552) attending 10 publi…
