Dimensions of oppositional defiant disorder in 3-year-old preschoolers / Lourdes EZPELETA in Journal of Child Psychology and Psychiatry, 53-11 (November 2012)
[article]
Titre : Dimensions of oppositional defiant disorder in 3-year-old preschoolers Type de document : Texte imprimé et/ou numérique Auteurs : Lourdes EZPELETA, Auteur ; Roser GRANERO, Auteur ; Nuria DE LA OSA CHAPARRO, Auteur ; Eva PENELO, Auteur ; Josep M. DOMENECH, Auteur Année de publication : 2012 Article en page(s) : p.1128-1138 Langues : Anglais (eng) Mots-clés : Comorbidity dimensions headstrong irritability negative affect oppositional defiant disorder preschool Trouble oppositionnel avec provocation Index. décimale : PER Périodiques Résumé : Background: To test the factor structure of oppositional defiant disorder (ODD) symptoms and to study the relationships between the proposed dimensions and external variables in a community sample of preschool children. Method: A sample of 1,341 3-year-old preschoolers was randomly selected and screened for a double-phase design. In total, 622 families were assessed with a diagnostic semi-structured interview and questionnaires on psychopathology, temperament and executive functioning completed by parents and teachers. Results: Using categorical and dimensional symptoms of ODD it was possible to confirm, cross-informant and cross-method, distinct dimensions for defining the structure of ODD: one made up of irritable and headstrong and the other of negative affect, oppositional behaviour and antagonistic behaviour. Specific associations with DSM-IV disorders were found, and irritable was associated with anxiety disorders, whereas headstrong was associated with disruptive disorders, including aggressive and non-aggressive CD symptoms. Also, negative affect was associated with anxiety disorders and non-aggressive CD symptoms, oppositional behaviour with disruptive disorders and aggressive CD symptoms, and antagonistic behaviours with disruptive disorders and, in boys, with mood disorders. The dimensions correlated with specific scales of psychopathology, temperament and executive functioning. Conclusions: Oppositional defiant disorder is a heterogeneous disorder from preschool age. Different dimensions, with moderate to acceptable reliability and convergent and discriminant validity with other psychological constructs, can be identified early in life.

In this exploratory three-wave longitudinal study spanning ages 9?19 years, we examined the associations between experiences of unpredictability, threat, and deprivation with the development of functional connectivity within and between three brain networks implicated in psychopathology: the salience (SAL), default mode (DMN), and fronto-parietal (FPN) networks, and tested whether network trajectories moderated associations between adversity and changes in internalizing symptoms. Connectivity decreased with age on average; these changes differed by dimension of adversity. Whereas family-level deprivation was associated with lower initial levels and more stability across most networks, unpredictability was associated with stability only in SAL connectivity, and threat was associated with stability in FPN and DMN-SAL connectivity. In youth exposed to higher levels of any adversity, lower initial levels and more stability in connectivity were related to smaller increases in internalizing symptoms. Our findings suggest that whereas deprivation is associated with widespread neurodevelopmental differences in cognitive and emotion processing networks, unpredictability is related selectively to salience detection circuitry. Studies with wider developmental windows should examine whether these neurodevelopmental alterations are adaptive or serve to maintain internalizing symptoms.

[article]
Titre : Annual Research Review: Re-thinking the classification of autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Catherine LORD, Auteur ; Rebecca M. JONES, Auteur Année de publication : 2012 Article en page(s) : p.490-509 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders dimensions classification diagnosisDSM-IV DSM-5 development; Index. décimale : PER Périodiques Résumé : Background: The nosology of autism spectrum disorders (ASD) is at a critical point in history as the field seeks to better define dimensions of social-communication deficits and restricted/repetitive behaviors on an individual level for both clinical and neurobiological purposes. These different dimensions also suggest an increasing need for quantitative measures that accurately map their differences, independent of developmental factors such as age, language level and IQ. Method: Psychometric measures, clinical observation as well as genetic, neurobiological and physiological research from toddlers, children and adults with ASD are reviewed. Results: The question of how to conceptualize ASDs along dimensions versus categories is discussed within the nosology of autism and the proposed changes to the DSM-5 and ICD-11. Differences across development are incorporated into the new classification frameworks. Conclusions: It is crucial to balance the needs of clinical practice in ASD diagnostic systems, with neurobiologically based theories that address the associations between social-communication and restricted/repetitive dimensions in individuals. Clarifying terminology, improving description of the core features of ASD and other dimensions that interact with them and providing more valid and reliable ways to quantify them, both for research and clinical purposes, will move forward both practice and science.
