ObjectiveAlthough substance use (SU) is elevated in ADHD and both are associated with disrupted emotional functioning, little is known about how emotions and SU interact in ADHD. We used a mixed qualitative-quantitative approach to explore this relationship.MethodNarrative comments were coded for 67 persistent (50 ADHD, 17 local normative comparison group [LNCG]) and 25 desistent (20 ADHD, 5 LNCG) substance users from the Multimodal Treatment Study of Children with ADHD (MTA) adult follow-up (21.7-26.7 years-old).ResultsSU persisters perceived SU positively affects emotional states and positive emotional effects outweigh negative effects. No ADHD group effects emerged. Qualitative analysis identified perceptions that cannabis enhanced positive mood for ADHD and LNCG SU persisters, and improved negative mood and ADHD for ADHD SU persisters.ConclusionPerceptions about SU broadly and mood do not differentiate ADHD and non-ADHD SU persisters. However, perceptions that cannabis is therapeutic may inform ADHD-related risk for cannabis use.

ObjectiveTo evaluate participants' perceptions about frequent use and reasons for substance use (SU) in the qualitative interview study, an add-on to the multimodal treatment study of ADHD (MTA).MethodUsing the longitudinal MTA database, 39 ADHD cases and 19 peers with Persistent SU, and 86 ADHD cases and 39 peers without Persistent SU were identified and recruited. In adulthood, an open-ended interview was administered, and SU excerpts were indexed and classified to create subtopics (frequent use and reasons for use of alcohol, marijuana, and other drugs).ResultsFor marijuana, the Persistent compared with Nonpersistent SU group had a significantly higher percentage of participants describing frequent use and giving reasons for use, and the ADHD group compared with the group of peers had a significantly higher percentage giving "stability" as a reason for use.ConclusionMotivations for persistent marijuana use may differ for adults with and without a history of ADHD.

AimsTo examine the association between developmental trajectories of inattention, hyperactivity-impulsivity and delinquency through childhood and adolescence (ages 8-16 years) and subsequent binge drinking and marijuana use in early adulthood (age 21 years).DesignProspective naturalistic follow-up of children with attention deficit/hyperactivity disorder (ADHD) previously enrolled in a randomized controlled trial (RCT). Treatment-phase assessments occurred at 3, 9 and 14 months after randomization; follow-up assessments occurred at 24 months, 36 months, and 6, 8 and 12 years after randomization.SettingSecondary analysis of data from the Multimodal Treatment Study of ADHD (MTA), a multi-site RCT comparing the effects of careful medication management, intensive behavior therapy, their combination, and referral to usual community care.ParticipantsA total of 579 children with DSM-IV ADHD combined type, aged 7.0 and 9.9 years at baseline (mean = 8.5, SD = 0.80).MeasurementsRatings of inattention, hyperactivity-impulsivity and delinquency were collected from multiple informants at baseline and through the 8-year follow-up. Self-reports of binge drinking and marijuana use were collected at the 12-year follow-up (mean age 21 years).FindingsTrajectories of worsening inattention symptoms and delinquency (and less apparent improvement in hyperactivity-impulsivity) were associated with higher rates of early adult binge drinking and marijuana use, compared with trajectories of stable or improving symptoms and delinquency (of 24 comparisons, all P-values

Individuals with attention-deficit/hyperactivity disorder (ADHD) are at increased risk for experiencing alcohol-related problems by adulthood. However, few studies have examined contextual factors that may contribute to this risk. The current study examined 1 widely investigated social-contextual risk factor, friend alcohol use, in a sample of adolescents with and without a history of ADHD. One hundred and 59 adolescents (14-17 years old) with childhood ADHD and 117 demographically similar youth without ADHD were interviewed annually in the Pittsburgh ADHD Longitudinal Study. Adolescents reported the frequency of their own alcohol use in the prior 12 months and the number of friends who used alcohol regularly or occasionally (perceived friend alcohol use). Multiple-group parallel process models indicated that increases in friend alcohol use were more strongly associated with increases in adolescent alcohol use over time for individuals with ADHD (r = .15, SE = 0.04; 95% confidence interval [CI] = [0.08, 0.22]) than for those without ADHD (r = .06, SE = 0.03; 95% CI [0.00, 0.11]). These results suggest that social factors are an important part of escalating alcohol use among adolescents with ADHD histories, and they highlight the possibility that interventions focused on the peer context could be important for these at-risk youth. Additional social network research on adolescent alcohol use within the larger context of other relationships (e.g., family and romantic relationships) is indicated. [ABSTRACT FROM AUTHOR]
