Article Synopsis
  • Individuals with ADHD are more likely to begin using substances during adolescence and struggle with substance use as adults, but the effects of psychosocial treatment for ADHD on substance use are not well understood.
  • In a study involving predominantly Latinx and Black rising ninth graders with ADHD, those who received a high-intensity treatment program were more likely to start using substances by the end of high school compared to those who received a lower intensity intervention.
  • The findings suggest that certain youths, particularly those with PTSD symptoms, may benefit from high-intensity treatment in terms of reduced substance use, highlighting the need for further research on the risks and benefits of ADHD treatments for different populations.

Introduction: Adolescents with attention-deficit/hyperactivity disorder (ADHD) may be at risk for early, escalating patterns of alcohol and substance use via academic, peer, and familial impairment. Existing school-based interventions for youth with ADHD effectively target these risk factors, yet their effects on alcohol and substance use have not been explored. We examined the immediate and long-term alcohol and substance use outcomes of an evidence-based school-based intervention for adolescents with ADHD.

Mental health and substance use fields suffer from underrepresentation of racially and ethnically minoritized, first-generation college student, and female members. The homogeny of the current workforce can impede scientific productivity, creativity, and problem-solving in addressing health-related issues. Our team developed the Teen Science Ambassador Program (TSAP) to provide underrepresented minoritized (URM) high school students with science-focused education, research opportunities, and mentoring within their community.

Article Synopsis
  • The study investigates how a parent's history of alcohol problems and antisocial behavior relates to adolescent alcohol use, particularly focusing on whether the child's ADHD status influences this relationship.
  • It involved 199 adolescents, with roughly half having ADHD, who assessed their perceptions of their parent’s drinking motives and reported their own alcohol use behaviors over the past year.
  • Results indicate that perceptions of parent drinking motives influenced adolescent alcohol use, especially in those without ADHD, suggesting the need for better communication about alcohol use between parents and their children.

Objective: We evaluated the effects of treatment compliance with the Challenging Horizons Program (CHP) for high school aged adolescents with attention-deficit hyperactivity disorder (ADHD).

Method: Participants were 185 high school aged adolescents (65% non-Hispanic White; 79% male) with a diagnosis of ADHD who were randomly assigned to either CHP or community control. Outcomes included parent-rated academic functioning, parent- and self-rated social-emotional functioning, and GPA.

This study evaluated whether an organization intervention was a mediator of change for grade point average (GPA) in a randomized clinical trial of a school-based treatment program for adolescents with attention deficit hyperactivity disorder (ADHD). A demographically diverse sample of 148 participants (105 males) with a diagnosis of ADHD were recruited from nine middle schools. Comprehensive diagnostic evaluations were completed and participants were randomized into one of three conditions (two active treatment conditions, one control condition) for a randomized clinical trial that lasted an entire school year.

Objective: The aim of this study was to examine the costs and cost-effectiveness of a school-based training intervention delivered at varying levels of intensity with adolescents with attention-deficit/hyperactivity disorder (ADHD). Costs were examined in relation to post-treatment and 6-month follow-up effects of the Challenging Horizons Program (CHP), a training intervention for adolescents with ADHD.

Method: A total of 326 middle-school students (71% male; 77% White) with ADHD were randomized to an after-school version of the CHP (CHP-AS), a less-intensive mentoring version (CHP-M), or routine community care.

Both qualitative and quantitative analyses were used to (a) describe the romantic and sexual relationships of adolescents with ADHD and (b) examine how ADHD-related impairments (e.g., social skill deficits and emotion dysregulation [ED]) are associated with romantic relationship outcomes in this group.

The purpose of the present study was to determine the role of emotion regulation in the pathway to problematic alcohol use among adolescents with attention-deficit/hyperactivity disorder (ADHD), specifically investigating the total effect of emotion regulation on problematic alcohol use and the indirect effect of emotion regulation through social skills on problematic alcohol use within a 2-wave longitudinal design. The potential protective effect of parent knowledge of these effects was assessed. Participants were 149 adolescents with ADHD (mean [] = 15.

Navigating academic demands in middle and high school may be particularly challenging for youth experiencing emotional and behavioral difficulties, and screening practices are a necessary first step in identifying youth in need of services. The goal of this study was to inform efficient universal screening practices in secondary schools by comparing 3 common methods of screening, including self- and teacher report on the Strengths and Difficulties Questionnaire, and grade point average (GPA) to indicate moderate and high levels of risk. Participants were 2,350 secondary students (47% female; 94% non-Hispanic White) and their teachers in 1 socioeconomically diverse school district.
