Research on planning, method choice, and method substitution in adolescents' suicide attempts is limited. We conducted in-depth interviews with 20 adolescents following their suicide attempt to learn the extent to which the attempt was planned, why they used the method they did, and whether they would have substituted another method if the one…

Reservation-dwelling American Indian adolescents are at exceedingly high risk for cannabis use. Prevention initiatives to delay the onset and escalation of use are needed. The risk and promotive factors approach to substance use prevention is a well-established framework for identifying the timing and targets for prevention initiatives. This study…

Background: To determine if school engagement is a viable target for early prevention of adolescent substance use, this study investigated whether school engagement in early adolescence (ages 12-14) is a cause of alcohol and cannabis use during middle to late adolescence (ages 15-19). Methods: To facilitate causal inference, inverse probability of…

It is important to prioritize intersectoral action at schools to prevent the use of alcohol and other drugs. This strategic act should be organized with multidisciplinary learning characteristics and with the involvement of different stakeholders. The aim of a recent scoping review was to identify the factors that benefit and hinder intersectoral…

Little is known about the outcomes of in-school comprehensive sexuality education (CSE) programmes two or more years after programme completion, particularly in low-income countries. "Projet Jeune Leader," a youth-founded Malagasy organisation, conducted a retrospective, qualitative evaluation of a CSE programme in Madagascar. The…

This study experimentally tested risk behavior outcomes of "Connecting," a low-cost, self-directed, family-based prevention program for families with youth placed in their care by state child welfare agencies. Families caring for youth aged 11 to 15 years from across Washington State were recruited and randomly assigned to either the…

Objective: Crack cocaine use has increased rapidly throughout Mexico, along with rising HIV and hepatitis C virus (HCV) infections among vulnerable groups. The Tirando Esquina: Interviniendo Muros de Salud (TE:IMS) project uses projection-mapping technology and is the first of its kind to reach and provide health education at an individual and…

Substance use represents a significant global health challenge that many countries lack the capacity to adequately address. While research has identified effective substance use practices and policies, utilization of this knowledge remains weak. Technology transfer is a process designed to accelerate the use of evidence in real-world settings.…

Several meta-analyses have demonstrated that bullying prevention programs are successful in reducing bullying. However, scant research addresses if and how such anti-bullying efforts affect long-term internalizing health problems and even less on later use of pharmacotherapy and psychotherapy. This study explores how the school-based Olweus…

Background: School-based substance use prevention is important, yet many educators are not trained in the curriculums. The purpose of this study was to assess changes in educators' knowledge about substances and confidence in delivering drug education before and after participating in educator trainings, as well as overall perceptions of the…

Objective: College students may not view sexual consent communication while under the influence of substances (i.e., alcohol and drugs) as problematic if media models the co-occurrence of these behaviors. The purpose of this study was to assess the types of consent cues used by characters who are and are not under the influence of substances in…

This study is a secondary data analysis that extends knowledge about the effects of the early childhood Family Check-Up (FCU) intervention to trajectories of general psychopathology problems (p factor) across early and middle childhood, and effects on adolescent psychopathology and polydrug use. The Early Steps Multisite study (ClinicalTrials.gov…

The current study describes an individual participant data meta-analysis (IPDMA) testing the efficacy of a peer-network counseling (PNC) intervention for preventing substance use escalation in adolescents and young adults. PNC has shown efficacy in reducing substance use among adolescents and young adults across small-scale randomized controlled…

This study employs a mixed-methods approach, combining quantitative and qualitative research methodologies to investigate the dynamics of leadership, management, and performance in the context of drug prevention within schools under local administrative organizations. The research pursues three main objectives: (1) to examine the key elements of…

Background: Comprehensive health education in schools can effectively prevent drug use and related outcomes, but successful implementation remains challenging. Contextual determinants, including intervention-setting compatibility, focus on the intervention, available resources, and leadership support, influence implementation success. This study…
