Attention deficit hyperactivity disorder (ADHD) comprises a deficit in behavioral inhibition. A theoretical model is constructed that links inhibition to 4 executive neuropsychological functions that appear to depend on it for their effective execution: (a) working memory, (b) self-regulation of affect-motivation-arousal, (c) internalization of speech, and(More)
OBJECTIVE Despite growing interest in adult attention deficit hyperactivity disorder (ADHD), little is known about its prevalence or correlates. METHOD A screen for adult ADHD was included in a probability subsample (N=3,199) of 18-44-year-old respondents in the National Comorbidity Survey Replication, a nationally representative household survey that(More)
OBJECTIVE Optimal diagnostic thresholds were determined for DSM-IV attention deficit hyperactivity disorder, and the psychometric properties were compared to alternative definitions. METHOD Structured diagnostic interviews of multiple informants for 380 clinic-referred youths aged 4-17 years were conducted. In addition, standardized clinicians' validation(More)
Neuropsychology has customarily taken a molecular and myopic view of executive functioning, concentrating largely on those proximal processes of which it may be comprised. Although commendable as a starting point, such an approach can never answer the question, “Why executive functioning?” The present paper encourages neuropsychologists to contemplate the(More)
BACKGROUND Despite growing interest in adult attention-deficit/hyperactivity disorder (ADHD), little is known about predictors of persistence of childhood cases into adulthood. METHODS A retrospective assessment of childhood ADHD, childhood risk factors, and a screen for adult ADHD were included in a sample of 3197 18-44 year old respondents in the(More)
This study examined the persistence of attention-deficit/hyperactivity disorder (ADHD) into young adulthood using hyperactive (N = 147) and community control (N = 71) children evaluated at ages 19-25 years. ADHD was rare in both groups (5% vs. 0%) based on self-report but was substantially higher using parent reports (46% vs. 1.4%). Using a developmentally(More)
The psychiatric outcome is reported for a large sample of hyperactive children (N = 123), meeting research diagnostic criteria, and normal control children (N = 66) followed prospectively over an 8-year period into adolescence. Over 80% of the hyperactives were attention deficit hyperactivity disorder (ADHD) and 60% had either oppositional defiant disorder(More)
BACKGROUND Hyperactive/ADHD children are believed to be a greater risk for adolescent and young adult antisocial activity and drug use/abuse, particularly that subset having comorbid conduct problems/disorder. METHOD We report on the lifetime antisocial activities and illegal drug use self-reported at young adult follow-up (mean age 20-21 years; 13+ year(More)
Attention deficit hyperactivity disorder (ADHD) is increasingly recognized as a legitimate adult diagnostic category. Yet the nature of and comorbidities and adaptive impairments associated with adult ADHD have received little scientific investigation. The present study, therefore, compared 172 adults diagnosed with ADHD with 30 adults referred to the same(More)
