ADHD and delay aversion: the influence of non-temporal stimulation on choice for delayed rewards / Inge ANTROP in Journal of Child Psychology and Psychiatry, 47-11 (November 2006)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 47-11 (November 2006) . - p.1152–1158 Titre : ADHD and delay aversion: the influence of non-temporal stimulation on choice for delayed rewards Type de document : Texte imprimé et/ou numérique Auteurs : Inge ANTROP, Auteur ; Herbert ROEYERS, Auteur ; Dieter BAEYENS, Auteur ; Pieter STOCK, Auteur ; Sylvie VERTE, Auteur ; Jan R. WIERSEMA, Auteur Année de publication : 2007 Article en page(s) : p.1152–1158 Langues : Anglais (eng) Mots-clés : Delay-aversion Index. décimale : PER Périodiques Résumé : Background: Delay aversion, the motivation to escape or avoid delay, results in preference for small immediate over large delayed rewards. Delay aversion has been proposed as one distinctive psychological process that may underlie the behavioural symptoms and cognitive deficits of attention deficit/hyperactivity disorder (ADHD). Furthermore, the delay aversion hypothesis predicts that ADHD children's preference for immediate small over large delayed rewards will be reduced when stimulation, which makes time appear to pass more quickly, is added to the delay interval. The current paper tests these predictions. Methods: A group of children with a diagnosis of ADHD (with or without oppositional defiant disorder (ODD)), a group with a diagnosis of high-functioning autism (HFA), and a normal control group were compared on an experimental paradigm giving repeated choices between small immediate and large delayed rewards (Maudsley Index of Delay Aversion–MIDA) under two conditions (stimulation and no stimulation). Results: As predicted, ADHD children displayed a stronger preference than the HFA and control children for the small immediate rewards under the no-stimulation condition. The ADHD children preferences were normalised under the stimulation condition with no differences between the groups. This pattern of results was the same whether the ADHD children had comorbid ODD or not. Discussion: The findings from the MIDA are consistent with the delay aversion hypothesis of ADHD in showing that preference for small immediate rewards over large delayed rewards is a specific feature of ADHD and that this preference can be reduced by the addition of stimulation. Further research is required to better understand the emotional and motivational mechanisms underpinning delay aversion.

Stimulation Seeking and Hyperactivity in Children with ADHD / Inge ANTROP in Journal of Child Psychology and Psychiatry, 41-2 (February 2000)

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 41-2 (February 2000) . - p.225-231 Titre : Stimulation Seeking and Hyperactivity in Children with ADHD Type de document : Texte imprimé et/ou numérique Auteurs : Inge ANTROP, Auteur ; Herbert ROEYERS, Auteur ; Paulette VAN OOST, Auteur ; Ann BUYSSE, Auteur Année de publication : 2000 Article en page(s) : p.225-231 Langues : Anglais (eng) Mots-clés : Activity level  ADD/ADHD  behavioural measures  environmental influences  hyperactivity  stimulation seeking Index. décimale : PER Périodiques Résumé : Thirty hyperactive and 30 non-hyperactive children were confronted with a delay, consisting of a waiting situation of 15 minutes, either with or without extra stimulation provided by the presentation of a videotape. The behaviour of the child during the waiting period was videotaped and later coded by two naive observers. In line with theories that emphasise the stimulation-seeking function of hyperactive behaviours, such as the optimal stimulation account and the delay aversion theory, a group by stimulation effect was hypothesised. For two categories of activity this was found, with ADHD children displaying more activity than non-ADHD children in the no-stimulation but not in the stimulation condition. These data provide support for the stimulation-seeking function of certain features of ADHD hyperactivity.

Time-of-day effects in arousal: disrupted diurnal cortisol profiles in children with ADHD / Lindita IMERAJ in Journal of Child Psychology and Psychiatry, 53-7 (July 2012)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 53-7 (July 2012) . - p.782-789 Titre : Time-of-day effects in arousal: disrupted diurnal cortisol profiles in children with ADHD Type de document : Texte imprimé et/ou numérique Auteurs : Lindita IMERAJ, Auteur ; Inge ANTROP, Auteur ; Herbert ROEYERS, Auteur ; James D. SWANSON, Auteur ; Ellen DESCHEPPE, Auteur ; Sarah BAL, Auteur ; Dirk DEBOUTTE, Auteur Année de publication : 2012 Article en page(s) : p.782-789 Langues : Anglais (eng) Mots-clés : ADHD  ODD  circadian  HPA axis  cortisol  arousal Index. décimale : PER Périodiques Résumé : Background:  Fluctuations in attention-deficit hyperactivity disorder (ADHD) symptoms related to regulatory deficits in arousal states are themselves characterized by circadian rhythms. Although cortisol is an important circadian arousal-related marker, studies focusing on across-the-day cortisol variations in ADHD are scarce. There is no study with multiple measurements to take into account interday and intraday variability. Methods:  Salivary cortisol was sampled five times a day (awakening, 30 min after awakening, noon, 4 p.m., 8 p.m.) across five consecutive days in 33 children with ADHD (22 with and 11 without oppositional defiant disorder; ODD) and 33 class- and sex-matched controls (aged 6–12). The cortisol awakening response (increase from awakening to 30 min after awakening) and the diurnal cortisol profile (across-the-day variations) were compared for ADHD with ODD (ADHD + ODD) and without ODD (ADHD) subgroups and the control group. Results:  The cortisol awakening response was not significantly different between groups. However, longitudinal analyses to evaluate cortisol profiles across the day revealed a significant Group × Time effect (p < .001). More specifically, compared to each other, the ADHD subgroup showed a flatter slope with relative morning hypo-arousal and evening hyperarousal, whereas the ADHD + ODD subgroup showed a steeper slope with relative morning hyperarousal and evening hypo-arousal (p < .001). Conclusions:  Findings support time-related arousal disruptions in children with ADHD associated with the presence or absence of ODD comorbidity. We recommend research on cortisol in larger samples for a better understanding of arousal mechanisms involved in ADHD not only with and without ODD but also with other comorbidities which may have implications for timing of arousal-based treatments.
