Methods: 316 children who participated in the Multimodal Treatment Study of Children with ADHD (MTA) completed the Conners' Continuous Performance Test (CPT) at the 24-month assessment point. Outcome measures included standard CPT outcomes (e.g., errors of commission, mean hit reaction time (RT)) and RT indicators derived from an Ex-Gaussian distributional model (i.e., mu, sigma, and tau). Results: Analyses revealed significant effects of medication across all neuropsychological outcome measures. Results on the Ex-Gaussian outcome measures revealed that stimulant medication slows RT and reduces RT variability. Conclusions: This demonstrates the importance of including analytic strategies that can accurately model the actual distributional pattern, including the positive skew. Further, the results of the study relate to several theoretical models of ADHD.

Developmental processes in peer problems of children with attention-deficit/hyperactivity disorder in The Multimodal Treatment Study of Children With ADHD: Developmental cascades and vicious cycles / Dianna MURRAY-CLOSE in Development and Psychopathology, 22-4 (November 2010)

SWANSON, Auteur Année de publication : 2010 Article en page(s) : p.785-802 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : We examined the developmental processes involved in peer problems among children (M age = 10.41 years) previously diagnosed with attention-deficit/hyperactivity disorder (ADHD) at study entry (N = 536) and a comparison group (N = 284). Participants were followed over a 6-year period ranging from middle childhood to adolescence. At four assessment periods, measures of aggression, social skills, positive illusory biases (in the social and behavioral domains), and peer rejection were assessed. Results indicated that children from the ADHD group exhibited difficulties in each of these areas at the first assessment. Moreover, there were vicious cycles among problems over time. For example, peer rejection was related to impaired social skills, which in turn predicted later peer rejection. Problems also tended to spill over into other areas, which in turn compromised functioning in additional areas across development, leading to cascading effects over time. The findings held even when controlling for age and were similar for males and females, the ADHD and comparison groups, and among ADHD treatment groups. The results suggest that the peer problems among children with and without ADHD may reflect similar processes; however, children with ADHD exhibit greater difficulties negotiating important developmental tasks. Implications for interventions are discussed.

Explicit vs. applied theory of mind competence: A comparison of typically developing males, males with ASD, and males with ADHD / Tiffany L. HUTCHINS in Research in Autism Spectrum Disorders, 21 (January 2016)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 21 (January 2016) . - p.94-108 Titre : Explicit vs. applied theory of mind competence: A comparison of typically developing males, males with ASD, and males with ADHD Type de document : Texte imprimé et/ou numérique Auteurs : Tiffany L.

PRELOCK, Auteur ; Hope MORRIS, Auteur ; Joy BENNER, Auteur ; Timothy LAVIGNE, Auteur ; Betsy HOZA, Auteur Article en page(s) : p.94-108 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Attention deficit hyperactivity disorder  Theory of mind  Assessment  Children Index. décimale : PER Périodiques Résumé : Using laboratory-type Theory of Mind (ToM) tasks (our measure of ‘explicit’ ToM competence) and a more ecologically-valid measure of ToM (our measure of ‘applied’ ToM competence), we found that for composite scores, typically developing (TD) males performed near ceiling levels on both indices and age-matched males with autism spectrum disorder (ASD) performed near floor levels on both indices. The scores for age-matched males with attention-deficit hyperactivity disorder (ADHD) showed a different pattern such that the ADHD group had high scores on the explicit measure and low scores on the applied measure. Subscale scores (early, basic, advanced ToM) for the two indices also revealed that (1) despite variable complexity, explicit ToM almost always distinguished the ASD group from the other two groups but never distinguished the ADHD and TD groups and (2) level of complexity was critical for distinguishing groups with regard to applied ToM. We suggest that although children with ADHD can calculate the content of traditional laboratory ToM tasks, this explicit ToM competence fails to be applied and expressed in real world demonstrations of ToM (especially when advanced ToM skills are assessed). By contrast, the ToM difficulties of children with ASD seem to be attributable to a deeper metarepresentational deficit. Our results have implications for practice and extend current models of social cognition in developmental disabilities by isolating variable aspects of competence that predict specific and testable models for future research.

Moderate-to-vigorous physical activity and processing speed: predicting adaptive change in ADHD levels and related impairments in preschoolers / Betsy HOZA in Journal of Child Psychology and Psychiatry, 61-12 (December 2020)

Physical activity (PA) is known to have a broad spectrum of positive effects on the brain in school-age typically developing children (Centers for Disease Control and Prevention, 2010, The association between school based physical activity, including physical education, and academic performance. Atlanta, GA: U.S. Department of Health and Human Services), including functions impaired by ADHD (Halperin, Berwid, & O'Neill, 2014, Child and Adolescent Psychiatric Clinics of North America, 23, 899), yet links between PA and ADHD levels and impairments have rarely been studied in either typically developing or at-risk preschool children. Importantly, impaired processing speed (PS), though not a symptom of ADHD, is a robust neuropsychological correlate (Willcutt & Bidwell, 2011, Treating attention deficit hyperactivity disorder: Assessment and intervention in developmental context. Kingston, NJ: Civic Research Institute) that may indicate additional risk for ADHD. Hence, we examined whether baseline PS moderates the association between preschoolers' PA, specifically moderate-to-vigorous PA (MVPA), and changes in ADHD levels and related behaviors. METHOD: Eighty-five preschoolers (49.4% female; M(age)  = 4.14, SD(age)  = .64) were drawn from a larger study of the effects of the Kiddie Children and Teachers (CATs) on the Move PA program on school readiness. The sample was largely Head Start eligible (68.2%) and ethnically diverse. Hierarchical regressions were utilized to examine links between MVPA, averaged over a school year, and changes in inattention (IA), hyperactivity/impulsivity (HI), oppositional behaviors, moodiness, and peer functioning, and whether these associations varied based on baseline PS. RESULTS: Results indicated that for IA, HI, and peer functioning, higher amounts of MVPA were associated with greater adaptive change for those with lower (but not higher) levels of PS. CONCLUSIONS: Preschool MVPA may be a viable method of reducing ADHD levels and impairments for those with lower PS.
