It suggests we need to navigate a course between these two opposing extremes, seeing the proposed diet–behaviour link more as a hypothesis to test, than a truth to defend or a myth to debunk. It summarises the history and standing of the current diet-behaviour hypothesis and the use of dietary exclusions and dietary supplements for behaviour problems, in the light of current empirical evidence and the impetus this provides for further research in this field.

Research Review: Birth by caesarean section and development of autism spectrum disorder and attention-deficit/hyperactivity disorder: a systematic review and meta-analysis / Eileen A. CURRAN in Journal of Child Psychology and Psychiatry, 56-5 (May 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-5 (May 2015) . - p.500-508 Titre : Research Review: Birth by caesarean section and development of autism spectrum disorder and attention-deficit/hyperactivity disorder: a systematic review and meta-analysis Type de document : Texte imprimé et/ou numérique Auteurs : Eileen A.

KEARNEY, Auteur Article en page(s) : p.500-508 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  attention-deficit/hyperactivity disorder  Caesarean section Index. décimale : PER Périodiques Résumé : Background Given the growing prevalence of birth by Caesarean section (CS) worldwide, it is important to understand any long-term effects CS delivery may have on a child's development. We assessed the impact of mode of delivery on autism spectrum disorders (ASD) and attention-deficit/hyperactivity disorder (ADHD). Methods We conducted a systematic review of the literature in PubMed, Embase, CINAHL, PsycINFO and Web of Science up to 28 February 2014. No publication date, language, location or age restrictions were employed. Results Thirteen studies reported an adjusted estimate for CS-ASD, producing a pooled odds ratio (OR) of 1.23 (95% CI: 1.07, 1.40). Two studies reported an adjusted estimate for CS-ADHD, producing a pooled OR of 1.07 (95% CI: 0.86, 1.33). Conclusions Delivery by CS is associated with a modest increased odds of ASD, and possibly ADHD, when compared to vaginal delivery. Although the effect may be due to residual confounding, the current and accelerating rate of CS implies that even a small increase in the odds of disorders, such as ASD or ADHD, may have a large impact on the society as a whole. This warrants further investigation.

Reduction in behavior problems with omega-3 supplementation in children aged 8–16 years: a randomized, double-blind, placebo-controlled, stratified, parallel-group trial / Adrian RAINE in Journal of Child Psychology and Psychiatry, 56-5 (May 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-5 (May 2015) . - p.509-520 Titre : Reduction in behavior problems with omega-3 supplementation in children aged 8–16 years: a randomized, double-blind, placebo-controlled, stratified, parallel-group trial Type de document : Texte imprimé et/ou numérique Auteurs : Adrian RAINE, Auteur ; Jill PORTNOY, Auteur ; Jianghong LIU, Auteur ; Tashneem MAHOOMED, Auteur ; Joseph R. HIBBELN, Auteur Article en page(s) : p.509-520 Langues : Anglais (eng) Mots-clés : Omega-3  externalizing  internalizing  aggression  randomized trial Index. décimale : PER Périodiques Résumé : Background While limited evidence suggests that omega-3 supplementation may reduce antisocial behavior in children, studies have not reported on posttreatment follow-up and most treatment periods have been of short duration. This study tests the hypothesis that omega-3 supplementation over 6 months will reduce behavior problems in children both at the end of treatment and at 6 months post treatment. Methods In this randomized, double-blind, placebo-controlled, stratified, parallel-group trial, a community sample of 8–16 year old children were randomized into a treatment group (N = 100) and a placebo-control group (N = 100). The supplementation consisted of a fruit drink containing 1 g/day of omega-3 or a placebo consisting of the same fruit drink without omega-3. Participants, caregivers, and research assistants were blinded to group assignment. The primary outcome measures of externalizing and internalizing behavior problems were reported by both caregivers and their children in a laboratory setting at 0 months (baseline), 6 months (end of treatment) and 12 months (6 months post treatment), together with the secondary outcome measures of parental antisocial behavior. Data were analyzed on an intention-to-treat basis including all participants. Trial registration: ClinicalTrials.gov: http://clinicaltrials.gov/ct2/show/NCT02016079?term=mauritius&rank=2 Results Significant group × time interactions were observed with the treatment group showing long-term improvements in child behavior problems. The average posttreatment effect size was d = ?.59. Effects were documented for parent reports, but with the exception of proactive and reactive aggression, child-report data were nonsignificant. Parents whose children took omega-3 showed significant posttreatment reductions in their own antisocial and aggressive behavior. This improvement in caregiver behavior partly mediated the improvements observed in child behavior. Conclusions Findings provide initial evidence that omega-3 supplementation can produce sustained reductions in externalizing and internalizing behavior problems. Results are the first to report improvements in caregiver behavior, and to establish this improvement as a part-mechanism for the efficacy of omega-3.

Neurocognitive deficits may predict the increased risk of developing SUDs and nicotine dependence. Methods This study comprised three groups derived from the Dutch part of the International Multicenter ADHD Genetics (IMAGE) study: ADHD probands (n = 294), unaffected siblings (n = 161), and controls (n = 214). At baseline (age = 12.2), a range of neurocognitive functions was assessed including executive functions (inhibition, working memory, timing), measures of motor functioning (motor timing and tracking) and IQ. After a mean follow-up of 4.2 years, SUDs and ND were assessed. Results None of the neurocognitive functions predicted later SUDs or ND in ADHD probands, even after controlling for medication use and conduct disorder. Slower response inhibition predicted later nicotine dependence in unaffected siblings (OR = 2.06, 95% CI = 1.22–3.48), and lower IQ predicted increased risk for SUDs in controls (OR = 1.96, 95% CI = 1.12–3.44). Conclusions Cold executive functions, motor functioning, and IQ did not predict the elevated risk of SUDs and ND in ADHD. Future studies should target ‘hot’ executive functions such as reward processing as risk factors for SUDs or ND.

Mothering, fathering, and the regulation of negative and positive emotions in high-functioning preschoolers with autism spectrum disorder / Yael HIRSCHLER-GUTTENBERG in Journal of Child Psychology and Psychiatry, 56-5 (May 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-5 (May 2015) . - p.530-539 Titre : Mothering, fathering, and the regulation of negative and positive emotions in high-functioning preschoolers with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Yael HIRSCHLER-GUTTENBERG, Auteur ; Ofer GOLAN, Auteur ; Sharon OSTFELD-ETZION, Auteur ; Ruth FELDMAN, Auteur Article en page(s) : p.530-539 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  emotion regulation  emotional reactivity  mothering  fathering Index. décimale : PER Périodiques Résumé : Background Children with autism spectrum disorder (ASD) exhibit difficulties in regulating emotions and authors have called to study the specific processes underpinning emotion regulation (ER) in ASD. Yet, little observational research examined the strategies preschoolers with ASD use to regulate negative and positive emotions in the presence of their mothers and fathers. Methods Forty preschoolers with ASD and 40 matched typically developing children and their mothers and fathers participated. Families were visited twice for identical battery of paradigms with mother or father. Parent–child interactions were coded for parent and child behaviors and children engaged in ER paradigms eliciting negative (fear) and positive (joy) emotions with each parent. ER paradigms were microcoded for negative and positive emotionality, ER strategies, and parent regulation facilitation. Results During free play, mothers' and fathers' sensitivity and warm discipline were comparable across groups; however, children with ASD displayed lower positive engagement and higher withdrawal. During ER paradigms, children with ASD expressed less positive emotionality overall and more negative emotionality during fear with father. Children with ASD used more simple self-regulatory strategies, particularly during fear, but expressed comparable levels of assistance seeking behavior toward mother and father in negative and positive contexts. Parents of children with ASD used less complex regulation facilitation strategies, including cognitive reappraisal and emotional reframing, and employed simple tactics, such as physical comforting to manage fear and social gaze to maintain joy. Conclusion Findings describe general and parent- and emotion-specific processes of child ER and parent regulation facilitation in preschoolers with ASD. Results underscore the ability of such children to seek parental assistance during moments of high arousal and the parents' sensitive adaptation to their children's needs. Reduced positive emotionality, rather than increased negative reactivity and self-regulatory efforts, emerges as the consistent element associated with ER processes in this group.

Insecure attachment during infancy predicts greater amygdala volumes in early adulthood / Christina MOUTSIANA in Journal of Child Psychology and Psychiatry, 56-5 (May 2015)

In a 22-year longitudinal study, we examined hippocampal and amygdala volumes in adulthood in relation to early infant attachment status, an important indicator of the quality of the early caregiving environment. Methods Participants (N = 59) were derived from a prospective longitudinal study of the impact of maternal postnatal depression on child development. Infant attachment status (24 Secure; 35 Insecure) was observed at 18 months of age, and MRI assessments were completed at 22 years. Results In line with hypotheses, insecure versus secure infant attachment status was associated with larger amygdala volumes in young adults, an effect that was not accounted for by maternal depression history. We did not find early infant attachment status to predict hippocampal volumes. Conclusions Common variations in the quality of early environment are associated with gross alterations in amygdala morphology in the adult brain. Further research is required to establish the neural changes that underpin the volumetric differences reported here, and any functional implications.

Maladaptive social information processing in childhood predicts young men's atypical amygdala reactivity to threat / Daniel Ewon CHOE in Journal of Child Psychology and Psychiatry, 56-5 (May 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-5 (May 2015) . - p.549-557 Titre : Maladaptive social information processing in childhood predicts young men's atypical amygdala reactivity to threat Type de document : Texte imprimé et/ou numérique Auteurs : Daniel Ewon CHOE, Auteur ; Daniel S. SHAW, Auteur ; Erika E. FORBES, Auteur Article en page(s) : p.549-557 Langues : Anglais (eng) Mots-clés : Amygdala  social information processing  hostile attribution  aggression  functional magnetic resonance imaging Index. décimale : PER Périodiques Résumé : Background Maladaptive social information processing, such as hostile attributional bias and aggressive response generation, is associated with childhood maladjustment. Although social information processing problems are correlated with heightened physiological responses to social threat, few studies have examined their associations with neural threat circuitry, specifically amygdala activation to social threat. Methods A cohort of 310 boys participated in an ongoing longitudinal study and completed questionnaires and laboratory tasks assessing their social and cognitive characteristics the boys were between 10 and 12 years of age. At age 20, 178 of these young men underwent functional magnetic resonance imaging and a social threat task. At age 22, adult criminal arrest records and self-reports of impulsiveness were obtained. Results Path models indicated that maladaptive social information-processing at ages 10 and 11 predicted increased left amygdala reactivity to fear faces, an ambiguous threat, at age 20 while accounting for childhood antisocial behavior, empathy, IQ, and socioeconomic status. Exploratory analyses indicated that aggressive response generation – the tendency to respond to threat with reactive aggression – predicted left amygdala reactivity to fear faces and was concurrently associated with empathy, antisocial behavior, and hostile attributional bias, whereas hostile attributional bias correlated with IQ. Although unrelated to social information-processing problems, bilateral amygdala reactivity to anger faces at age 20 was unexpectedly predicted by low IQ at age 11. Amygdala activation did not mediate associations between social information processing and number of criminal arrests, but both impulsiveness at age 22 and arrests were correlated with right amygdala reactivity to anger facial expressions at age 20. Conclusions Childhood social information processing and IQ predicted young men's amygdala response to threat a decade later, which suggests that childhood social-cognitive characteristics are associated with the development of neural threat processing and adult adjustment.

Although unrelated to social information-processing problems, bilateral amygdala reactivity to anger faces at age 20 was unexpectedly predicted by low IQ at age 11. Amygdala activation did not mediate associations between social information processing and number of criminal arrests, but both impulsiveness at age 22 and arrests were correlated with right amygdala reactivity to anger facial expressions at age 20. Conclusions Childhood social information processing and IQ predicted young men's amygdala response to threat a decade later, which suggests that childhood social-cognitive characteristics are associated with the development of neural threat processing and adult adjustment.

This study aimed to investigate the prevalence and clinical significance of PE in preadolescent children from the general population by use of in-depth psychopathological interviews and comprehensive diagnostic assessments. Methods We investigated 1,632 children from the general population-based Copenhagen Child Cohort 2000. PE were measured by semistructured interviews using the K-SADS-PL-items on psychotic and affective symptoms, each symptom scored as not present versus likely or definitely present. The Development and Well-Being Assessment (DAWBA) was used independently to diagnose DSM-IV-mental disorders. Puberty development and sleep disturbance were self-reported. The associations between PE (any lifetime hallucination and/or delusion) and various mental problems and disorders were examined by multivariable binomial regression analyses, adjusting for gender and onset of puberty. Results The weighted life time prevalence of PE at age 11–12 years was 10.9% (CI 9.1–12.7). The majority of children with PE (n = 172) either had a diagnosable DSM-IV-mental disorder (31.4%) or self-reported mental health difficulties in absence of a diagnosis (31.4%). The risk of delusions increased with onset of puberty. The risk of PE increased with emotional and neurodevelopmental disorders, subthreshold depressive symptoms, sleep problems and lack of sleep, regardless of whether PE were expressed as hallucinations and/or delusions. The highest correlations were seen for emotional and multiple disorders. Conclusions Psychotic experiences are particularly prevalent in the context of affective dysregulation and sleep disturbance, increase with onset of puberty and represent a trans-diagnostic marker of psychopathology.

Working memory and cognitive flexibility-training for children with an autism spectrum disorder: a randomized controlled trial / Marieke DE VRIES in Journal of Child Psychology and Psychiatry, 56-5 (May 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-5 (May 2015) . - p.566-576 Titre : Working memory and cognitive flexibility-training for children with an autism spectrum disorder: a randomized controlled trial Type de document : Texte imprimé et/ou numérique Auteurs : Marieke DE VRIES, Auteur ; Pier J. M. PRINS, Auteur ; Ben A. SCHMAND, Auteur ; Hilde M. GEURTS, Auteur Article en page(s) : p.566-576 Langues : Anglais (eng) Mots-clés : Executive functioning  working memory  flexibility  cognitive training  autism Index. décimale : PER Périodiques Résumé : Background People with autism spectrum disorders (ASDs) experience executive function (EF) deficits. There is an urgent need for effective interventions, but in spite of the increasing research focus on computerized cognitive training, this has not been studied in ASD. Hence, we investigated two EF training conditions in children with ASD. Methods In a randomized controlled trial, children with ASD (n = 121, 8–12 years, IQ > 80) were randomly assigned to an adaptive working memory (WM) training, an adaptive cognitive flexibility-training, or a non-adaptive control training (mock-training). Braingame Brian, a computerized EF-training with game-elements, was used. Outcome measures (pretraining, post-training, and 6-week-follow-up) were near-transfer to trained EFs, far-transfer to other EFs (sustained attention and inhibition), and parent's ratings of daily life EFs, social behavior, attention deficit hyperactivity disorder (ADHD)-behavior, and quality of life. Results Attrition-rate was 26%. Children in all conditions who completed the training improved in WM, cognitive flexibility, attention, and on parent's ratings, but not in inhibition. There were no significant differential intervention effects, although children in the WM condition showed a trend toward improvement on near-transfer WM and ADHD-behavior, and children in the cognitive flexibility condition showed a trend toward improvement on near-transfer flexibility. Conclusion Although children in the WM condition tended to improve more in WM and ADHD-behavior, the lack of differential improvement on most outcome measures, the absence of a clear effect of the adaptive training compared to the mock-training, and the high attrition rate suggest that the training in its present form is probably not suitable for children with ASD.

Three experiments were conducted to determine whether caregiver reports of past and current behaviors are affected by question timing and ordering. Methods Using the Autism Diagnostic Interview – Revised (ADI-R), two studies systematically varied the order in which caregivers were asked about behaviors. In a third study, descriptions of children's current behaviors at age 5 were compared to retrospective descriptions of behaviors at age 5 collected at age 10. Results Caregivers, who were first asked about a history of symptoms, described less severe past and present behavior than caregivers reporting current behaviors as well as caregivers reporting current and history of symptoms together. Caregivers retrospectively reported more severe behaviors for age 5 when their children were age 10 than they had when their children were age 5. Conclusions Caregivers describe past behaviors differently depending on whether they are asked about current symptoms first. Methods of caregiver reporting can influence interpretations of symptom severity with effects on diagnoses and research findings.

Genetic and environmental contributions to anxiety among Chinese children and adolescents – a multi-informant twin study / Jie CHEN in Journal of Child Psychology and Psychiatry, 56-5 (May 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-5 (May 2015) . - p.586-594 Titre : Genetic and environmental contributions to anxiety among Chinese children and adolescents – a multi-informant twin study Type de document : Texte imprimé et/ou numérique Auteurs : Jie CHEN, Auteur ; Jing YU, Auteur ; Xinying LI, Auteur ; Jianxin ZHANG, Auteur Article en page(s) : p.586-594 Langues : Anglais (eng) Mots-clés : Anxiety  Chinese children and adolescents  genetic and environmental influence  heritability  twin study Index. décimale : PER Périodiques Résumé : Background Child and adolescent anxiety has become a major public health concern in China, but little was known about the etiology of anxiety in Chinese children and adolescents. The present study aimed to investigate genetic and environmental influences on trait anxiety among Chinese children and adolescents. Rater, sex, and age differences on these estimates were also examined. Methods Self-reported and parent-reported child's trait anxiety was collected from 1,104 pairs of same-sex twins aged 9–18 years. Genetic models were fitted to data from each informant to determine the genetic (A), shared (C), and non-shared environmental (E) influences on trait anxiety. Results The parameter estimates and 95% confidence intervals (CI) of A, C, E on self-reported trait anxiety were 50% [30%, 60%], 5% [0%, 24%], 45% [40%, 49%]. For parent-reported data, the corresponding parameter estimates were 63% [47%, 78%], 13% [1%, 28%], and 24% [22%, 27%], respectively. The heritability of anxiety was higher in girls for self-reported data, but higher in boys for parent-reported data. There was no significant age difference in genetic and environmental contributions for self-reported data, but a significant increase of heritability with age for parent-reported data. Conclusions The trait anxiety in Chinese children and adolescents was highly heritable. Non-shared environmental factors also played an important role. The estimates of genetic and environmental effects differed by rater, sex and age. Our findings largely suggest the cross-cultural generalizability of the etiological model of child and adolescent anxiety.
