Childhood ADHD and Growth in Adolescent Alcohol Use: The Roles of Functional Impairments, ADHD Symptom Persistence, and Parental Knowledge

Research on the relation between childhood Attention-Deficit/Hyperactivity Disorder (ADHD) and adolescent alcohol use has found mixed results. Studies are needed that operationalize alcohol use in developmentally appropriate ways and that test theoretically plausible moderators and mediators in a longitudinal framework. The current study tested childhood ADHD as a predictor of alcohol use frequency at age 17, and age-related increases in alcohol use frequency, through adolescence for 163 adolescents with ADHD diagnosed in childhood and 120 adolescents without ADHD histories. Childhood ADHD did not predict either alcohol outcome. However, parental knowledge of the teen’s friendships, activities, and whereabouts moderated the association such that childhood ADHD predicted alcohol use frequency at age 17 when parental knowledge was below median levels for the sample. Mediational pathways that explained this risk included social impairment, persistence of ADHD symptoms, grade point average, and delinquency. Social impairment was positively associated with alcohol use frequency through delinquency; it was negatively associated with alcohol use frequency as a direct effect independent of delinquency. These nuanced moderated-mediation findings help to explain previously inconsistent results for the ADHD-adolescent alcohol use association. The findings also imply that future research and intervention efforts should focus on ADHD-related social and academic impairments as well as symptom persistence and parenting efforts

Modifying an evidence-based summer treatment program for use in a summer school setting: A pilot effectiveness evaluation

This report evaluates a pilot implementation of a modified version of the Summer Treatment Program (STP, Pelham et al. in Evidence-based psychotherapies for children and adolescents. The Guilford Press, New York, 2010) as an afternoon adjunct to a mandatory summer school curriculum in three inner city elementary schools (Summer School STP, SSSTP). Using preliminary post-test measures, the SSSTP was compared with afternoon adjunct programs implemented in two comparison schools. Students in pre-kindergarten through sixth grade who failed to meet grade-level requirements for grade promotion were required to attend the program and served as participants (SSSTP n = 585, Comparison n = 686). Measures collected include the following: student self-reports, teachers’ program evaluations, staff evaluations (of students, program, benefit to self), staff ratings of benefit to junior counselors (i.e., adolescent employees), and independent observations. Results suggest that the SSSTP is an acceptable and feasible adjunctive intervention for the summer school setting in inner city schools. Further research is needed to examine academic and therapeutic benefits. (PsycINFO Database Record (c) 2013 APA, all rights reserved). (journal abstract

Efficacy of a Methylphenidate Transdermal System Versus t.i.d. Methylphenidate in a Laboratory Setting

Objective: To test the efficacy and tolerability of the methylphenidate transdermal formulation (MTS) against immediate-release methylphenidate (IR MPH) and placebo in a 12-hr analog classroom setting. Method: A total of nine boys ages 6 to 9 years, medicated with MPH for ADHD, complete a within-subject, double-blind study. For the purpose of the study, the boys are administered a dose of 20 cm 2 MTS, a matched dose of IR MPH 10 mg TID, and placebo. ADHD symptoms and frequency counts of classroom rule violations and the number of math problems completed are assessed hourly, during three consecutive analog classroom sessions. Results: Findings show that, across measures and throughout the day, both treatments significantly differentiated from placebo (p \u3c .05) but not from each other. It is also observed that the MTS produced more consistent results across the day but had a delayed onset versus IR MPH. Both medications are well tolerated with only mild reductions in sleep onset. Conclusion: The MTS demonstrates comparable efficacy and tolerability to TID IR MPH. © 2011 SAGE Publications
