A randomized controlled trial of Hanen’s ‘More Than Words’ in toddlers with early autism symptoms / Alice S. CARTER in Journal of Child Psychology and Psychiatry, 52-7 (July 2011)

Methods: Sixty-two children (51 boys and 11 girls; M age = 20 months; SD = 2.6) who met criteria for autism spectrum disorders (ASD) and their parents participated in the study. The HMTW intervention was provided over 3.5 months. There were three measurement periods: prior to randomization (Time 1) and at 5 and 9 months post enrollment (Times 2 and 3). Children’s communication and parental responsivity were measured at each time point. Children’s object interest, a putative moderator, was measured at Time 1. Results: There were no main effects of the HMTW intervention on either parental responsivity or children’s communication. However, the effects on residualized gains in parental responsivity from Time 1 to both Times 2 and 3 yielded noteworthy effect sizes (Glass’s Δ = .71, .50 respectively). In contrast, there were treatment effects on child communication gains to Time 3 that were moderated by children’s Time 1 object interest. Children with lower levels of Time 1 object interest exhibited facilitated growth in communication; children with higher levels of object interest exhibited growth attenuation. Conclusions: The HMTW intervention showed differential effects on child communication depending on a baseline child factor. HMTW facilitated communication in children with lower levels of Time 1 object interest. Parents of children who evidence higher object interest may require greater support to implement the HMTW strategies, or may require different strategies than those provided by the HMTW curriculum.

Telescoping of caregiver report on the Autism Diagnostic Interview – Revised / Vanessa HUS in Journal of Child Psychology and Psychiatry, 52-7 (July 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-7 (July 2011) . - p.753-760 Titre : Telescoping of caregiver report on the Autism Diagnostic Interview – Revised Type de document : Texte imprimé et/ou numérique Auteurs : Vanessa HUS, Auteur ; Amanda M. TAYLOR, Auteur ; Catherine LORD, Auteur Année de publication : 2011 Article en page(s) : p.753-760 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  telescoping  retrospective caregiver-report  language milestones Index. décimale : PER Périodiques Résumé : Background:  Delays in development are a fundamental feature in diagnosing autism spectrum disorders (ASD). Age of language acquisition, usually obtained through retrospective caregiver report, is currently used to distinguish between categories within ASD. Research has shown that caregivers often report children as having acquired developmental milestones earlier or later than they were actually achieved. The current study examines the extent to which this phenomenon, referred to as ‘telescoping,’ impacts retrospective reports provided by caregivers of children with ASD. Methods:  Participants were 127 caregivers of children referred for possible ASD or non-spectrum developmental delay. Caregivers were interviewed when children were 2, 3, 5, and 9 years of age. Caregiver-reported ages of first concern, language and non-diagnostic developmental milestones and interviewer-estimated age of onset were compared over time using linear models. Results:  Significant telescoping of language milestones resulted in more children meeting language delay criteria as they grew older, in spite of original reports that their language was not delayed. There was little evidence of consistent telescoping of caregiver-reported ages of first concern, daytime bladder control, and independent walking. With time, the interviewers’ judged ages of symptom onset increased, but remained prior to age three. Conclusions:  Telescoping of caregiver-reported ages of language acquisition has implications for both clinical diagnosis and genetic studies using these milestones to increase homogeneity of samples. Results support proposals to remove specific age-based criteria in the diagnosis of ASD. Telescoping should be considered when working with any clinical population in which retrospectively recalled events are used in diagnosis.

Task-related default mode network modulation and inhibitory control in ADHD: effects of motivation and methylphenidate / Elizabeth B. LIDDLE in Journal of Child Psychology and Psychiatry, 52-7 (July 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-7 (July 2011) . - p.761-771 Titre : Task-related default mode network modulation and inhibitory control in ADHD: effects of motivation and methylphenidate Type de document : Texte imprimé et/ou numérique Auteurs : Elizabeth B.

LIDDLE, Auteur Année de publication : 2011 Article en page(s) : p.761-771 Langues : Anglais (eng) Mots-clés : Attention deficit/hyperactivity disorder  default mode network  inhibitory control  motivation  methylphenidate Index. décimale : PER Périodiques Résumé : Background:  Deficits characteristic of attention deficit/hyperactivity disorder (ADHD), including poor attention and inhibitory control, are at least partially alleviated by factors that increase engagement of attention, suggesting a hypodopaminergic reward deficit. Lapses of attention are associated with attenuated deactivation of the default mode network (DMN), a distributed brain system normally deactivated during tasks requiring attention to the external world. Task-related DMN deactivation has been shown to be attenuated in ADHD relative to controls. We hypothesised that motivational incentives to balance speed against restraint would increase task engagement during an inhibitory control task, enhancing DMN deactivation in ADHD. We also hypothesised that methylphenidate, an indirect dopamine agonist, would tend to normalise abnormal patterns of DMN deactivation. Method:  We obtained functional magnetic resonance images from 18 methylphenidate-responsive children with ADHD (DSM-IV combined subtype) and 18 pairwise-matched typically developing children aged 9–15 years while they performed a paced Go/No-go task. We manipulated motivational incentive to balance response speed against inhibitory control, and tested children with ADHD both on and off methylphenidate. Results:  When children with ADHD were off-methylphenidate and task incentive was low, event-related DMN deactivation was significantly attenuated compared to controls, but the two groups did not differ under high motivational incentives. The modulation of DMN deactivation by incentive in the children with ADHD, off-methylphenidate, was statistically significant, and significantly greater than in typically developing children. When children with ADHD were on-methylphenidate, motivational modulation of event-related DMN deactivation was abolished, and no attenuation relative to their typically developing peers was apparent in either motivational condition. Conclusions:  During an inhibitory control task, children with ADHD exhibit a raised motivational threshold at which task-relevant stimuli become sufficiently salient to deactivate the DMN. Treatment with methylphenidate normalises this threshold, rendering their pattern of task-related DMN deactivation indistinguishable from that of typically developing children.

Delighted when approved by others, to pieces when rejected: children’s social anxiety magnifies the linkage between self- and other-evaluations / Albert REIJNTJES in Journal of Child Psychology and Psychiatry, 52-7 (July 2011)

However, the extent to which they base their momentary feelings of self-worth (i.e., state self-esteem) on social (dis)approval is unclear. It is also unclear whether this exceedingly approval-based self-esteem is a common correlate of social anxiety and depression, or specifically linked to one or the other. Methods:  Changes in children’s state self-esteem were obtained in response to a manipulated peer evaluation outcome. Participants (N = 188) aged 10 to 13 took part in a rigged online computer contest and were randomized to receive positive or negative peer feedback. Self-reported state self-esteem was assessed via computer at baseline and immediately post-feedback. The predictive effects of self-reported social anxiety and depression symptoms on changes in state self-esteem were investigated. Results:  Hierarchical multiple regression analyses showed that children with higher social anxiety, as indexed by the fear of negative evaluation component, experienced significantly stronger increases in state self-esteem following peer approval (β = .26, p < .05), and significantly stronger decreases in state self-esteem following peer disapproval (β =−.23, p < .05). In both conditions depressive symptoms did not predict changes in state self-esteem (ps > .20). Conclusions:  Socially anxious children’s state self-esteem is strongly contingent on social approval. Because basing one’s self-esteem on external validation has multiple negative consequences, these findings highlight the importance of teaching these children skills (e.g., making cognitive reappraisals) to weaken the linkage between other- and self-evaluations.

Developmental trajectories of positive and negative affect in children at high and low familial risk for depressive disorder / Thomas M. OLINO in Journal of Child Psychology and Psychiatry, 52-7 (July 2011)

OLINO, Auteur ; Nestor L. LOPEZ-DURAN, Auteur ; Maria KOVACS, Auteur ; Charles J. GEORGE, Auteur ; Amy L. GENTZLER, Auteur ; Daniel S. SHAW, Auteur Année de publication : 2011 Article en page(s) : p.792-799 Langues : Anglais (eng) Mots-clés : Positive affect  negative affect  depression risk  developmental trajectories Index. décimale : PER Périodiques Résumé : Background:  Although low positive affect (PA) and high negative affect (NA) have been posited to predispose to depressive disorders, little is known about the developmental trajectories of these affects in children at familial risk for mood disorders. Methods:  We examined 202 offspring of mothers who had a history of juvenile-onset unipolar depressive disorder (n = 60) or no history of major psychopathology (n = 80). Offspring participated in up to seven annual, structured laboratory tasks that were designed to elicit PA and NA. Results:  Growth curve analyses revealed that PA increased linearly and similarly for all children from late infancy through age 9. However, there also were individual differences in early PA. Relative to control peers, offspring of mothers with lifetime unipolar depression had consistently lower levels of PA, and this association remained significant even when controlling for current maternal depression and maternal affect displays. Growth curve analyses also revealed a significant linear decrease in NA in children across time; however, there was no significant inter-individual variation either in early NA or rate of change in NA. Conclusion:  Attenuated PA (rather than excessive NA) may be an early vulnerability factor for eventual unipolar depressive disorder in at-risk children and may represent one pathway through which depression is transmitted.

Methods:  We examined 202 offspring of mothers who had a history of juvenile-onset unipolar depressive disorder (n = 60) or no history of major psychopathology (n = 80). Offspring participated in up to seven annual, structured laboratory tasks that were designed to elicit PA and NA. Results:  Growth curve analyses revealed that PA increased linearly and similarly for all children from late infancy through age 9. However, there also were individual differences in early PA. Relative to control peers, offspring of mothers with lifetime unipolar depression had consistently lower levels of PA, and this association remained significant even when controlling for current maternal depression and maternal affect displays. Growth curve analyses also revealed a significant linear decrease in NA in children across time; however, there was no significant inter-individual variation either in early NA or rate of change in NA. Conclusion:  Attenuated PA (rather than excessive NA) may be an early vulnerability factor for eventual unipolar depressive disorder in at-risk children and may represent one pathway through which depression is transmitted.

Maternal eating disorders and infant feeding difficulties: maternal and child mediators in a longitudinal general population study / Nadia MICALI in Journal of Child Psychology and Psychiatry, 52-7 (July 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-7 (July 2011) . - p.800-807 Titre : Maternal eating disorders and infant feeding difficulties: maternal and child mediators in a longitudinal general population study Type de document : Texte imprimé et/ou numérique Auteurs : Nadia MICALI, Auteur ; Emily SIMONOFF, Auteur ; Daniel STAHL, Auteur ; Janet TREASURE, Auteur Année de publication : 2011 Article en page(s) : p.800-807 Langues : Anglais (eng) Mots-clés : ALSPAC  eating disorders  feeding  anxiety  depression;infants Index. décimale : PER Périodiques Résumé : Background:  Maternal eating disorders (ED) have been shown to increase the risk of feeding difficulties in the offspring. Very few studies, however, have investigated whether the effect of a maternal ED on childhood feeding is a direct effect or whether it can be ascribed to other child or maternal factors. We aimed to determine the role of maternal anxiety and depression in mediating the risk for feeding difficulties in infants of women with ED. Methods:  A prospective study comparing women with lifetime ED (441) and without any lifetime psychiatric disorder (10,461) and their infants from the Avon Longitudinal Study of Parents and Children (ALSPAC). We investigated the effect of: maternal anxiety and depression in late pregnancy (32 weeks) and the post-partum (8 weeks), child temperament and developmental status on infant feeding difficulties at 1 and 6 months. We also investigated the effect of active pregnancy ED symptoms. We tested 3 models and their fit to the data using structured equation modelling: a direct effect model, a fully mediational model and an integrated (partial meditational) model. Results:  The integrated model including a direct effect of maternal lifetime ED on infant feeding and a mediational path via maternal distress (a latent variable combining anxiety and depression) fitted the data best. This also applied to maternal pregnancy ED symptoms. Feeding difficulties in turn increased maternal distress over time. Conclusions:  Lifetime ED and active pregnancy ED increase the risk for infant feeding difficulties and do so via maternal distress (i.e., depression and anxiety). This has important implications for prevention and early intervention in relation to infant feeding difficulties, as well as for future research in the field.

Variability in post-error behavioral adjustment is associated with functional abnormalities in the temporal cortex in children with ADHD / Simona SPINELLI in Journal of Child Psychology and Psychiatry, 52-7 (July 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-7 (July 2011) . - p.808-816 Titre : Variability in post-error behavioral adjustment is associated with functional abnormalities in the temporal cortex in children with ADHD Type de document : Texte imprimé et/ou numérique Auteurs : Simona SPINELLI, Auteur ; Roma A. VASA, Auteur ; Suresh JOEL, Auteur ; Tess E. NELSON, Auteur ; James J. PEKAR, Auteur ; Stewart H. MOSTOFSKY, Auteur Année de publication : 2011 Article en page(s) : p.808-816 Langues : Anglais (eng) Mots-clés : Error processing  variability  temporal cortex  medial frontal cortex  ADD/ADHD  child  fMRI  brain imaging  distractibility  emotion regulation  reaction time Index. décimale : PER Périodiques Résumé : Background:  Error processing is reflected, behaviorally, by slower reaction times (RT) on trials immediately following an error (post-error). Children with attention-deficit hyperactivity disorder (ADHD) fail to show RT slowing and demonstrate increased intra-subject variability (ISV) on post-error trials. The neural correlates of these behavioral deficits remain unclear. The dorsal anterior cingulate cortex (ACC) and lateral prefrontal cortex (PFC) are key regions implicated in error processing and subsequent behavioral adjustment. We hypothesized that children with ADHD, compared to typically developing (TD) controls, would exhibit reduced PFC activation during post-error (versus post-correct inhibition) trials and reduced dACC activation during error (versus correct inhibition) trials. Methods:  Using functional Magnetic Resonance Imaging (fMRI) and a Go/No-Go task, we analyzed the neural correlates of error processing in 13 children with ADHD and 17 TD children. Results:  Behaviorally, children with ADHD showed similar RT slowing but increased ISV compared to controls. The post-error contrast revealed a relative increase in blood-oxygen-level dependent (BOLD) signal in the middle/inferior temporal cortex (TempC), the ACC/supplementary motor area (SMA) and the somatosensory/auditory cortex (AudC) in children with ADHD compared to controls. Importantly, in the ADHD group, increased post-error temporal cortex activity was associated with lower ISV. During error (versus correct inhibition) trials, no between-group differences were detected. However, in children with ADHD lower ISV was associated with decreased insula and increased precentral gyrus activity. Conclusions:  In children with ADHD, post-error neural activity suggests, first, a shift of attention towards task-irrelevant stimuli (AudC), and second, a recruitment of compensatory regions that resolve stimulus conflict (TempC) and improve response selection/execution (ACC/SMA). ADHD children with higher temporal cortex activation showed lower ISV, suggesting that functional abnormalities in the compensatory temporal regions contribute to increased variability. Moreover, increased ISV may be related to an over-sensitivity to negative outcomes during error trials in ADHD (insula correlation).
