Updating biological bases of social behavior / Thomas G. O'CONNOR in Journal of Child Psychology and Psychiatry, 55-9 (September 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-9 (September 2014) . - p.957-958 Titre : Updating biological bases of social behavior Type de document : Texte imprimé et/ou numérique Auteurs : Thomas G. O'CONNOR, Auteur Article en page(s) : p.957-958 Langues : Anglais (eng) Mots-clés : Social behaviours  cognitive development  mental phenomena  biological mechanisms Index. décimale : PER Périodiques Résumé : This month's collation of papers deals with social behaviors that operationalize key constructs in fields covered by the journal, including attachment theory and parenting; emotional regulation; psychopathology of several forms; general and specific cognitive abilities. Notably, many examples are offered of how these social behaviors link with biology. That is an obvious and important direction for clinical research insofar as it helps to erase a perceptual chasm and artificial duality between ‘behavior’ and ‘biology’. But, although it must be the case that social behavior has biological connections of one sort or other, identifying reliable connections with practical application has proved to be a non-trivial challenge. In particular, the challenge seems to be in measuring social behavior meaningfully enough that it could be expected to have a biological pulse, and in measuring biological markers systematically enough that emergent-downstream effects would surface. Associations are not especially uncommon, but it has been a frustrating task in constructing a practically broad model from a bricolage of scattered and disconnected parts and findings in the literature. Several reports in this issue offer contrasts that may help move along this line of study.

Practitioner Review: Long-term pharmacological treatment of pediatric bipolar disorder / Covadonga M. DIAZ-CANEJA in Journal of Child Psychology and Psychiatry, 55-9 (September 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-9 (September 2014) . - p.959-980 Titre : Practitioner Review: Long-term pharmacological treatment of pediatric bipolar disorder Type de document : Texte imprimé et/ou numérique Auteurs : Covadonga M.

In order to guide clinical practice, we review the efficacy and safety profile of mood stabilizers, antipsychotics, and other pharmacological strategies for the long-term treatment of BD in pediatric patients. Methods A MEDLINE, EMBASE, Cochrane and PsycInfo search (inception through November 2013) was performed to identify prospective studies longer than 12 weeks assessing the use of pharmacological strategies for the long-term treatment of BD in pediatric patients (0–18 years of age). Results Four randomized controlled trials (RCT) [three placebo-controlled (assessing aripiprazole (2) and flax oil), and one head-to-head comparison of lithium vs. divalproex], and thirteen noncontrolled studies (six open-label studies assessing lithium or anticonvulsants, five assessing second-generation antipsychotics (SGAs) and four assessing combination strategies) were included in the review. Aripiprazole has shown efficacy for relapse prevention in children with pediatric bipolar disorder (PBD) 4–9 years of age in one placebo-controlled RCT. Positive results have been reported in noncontrolled studies with quetiapine and lithium for relapse prevention, as well as with lithium, quetiapine, ziprasidone, and the combination of risperidone and divalproex or lithium for long-term symptom reduction in PBD. The most frequently reported adverse events in children and adolescents treated with lithium and anticonvulsants are gastrointestinal and neurological, whereas use of SGAs is mainly related to weight gain and sedation. Conclusion According to the limited empirical evidence, aripiprazole can be useful for relapse prevention in children with PBD. Given the lack of consistent efficacy data, clinical decision making should be based on individual clinical aspects and safety concerns.

Heart rate variability during social interactions in children with and without psychopathology: a meta-analysis / Sara SHAHRESTANI in Journal of Child Psychology and Psychiatry, 55-9 (September 2014)

Research has employed heart rate variability (HRV) during both socially engaging and socially disengaging dyadic tasks between children and adults to assess this. Methods We conducted a meta-analysis including evidence from 18 studies comprising 1,544 children who were categorized as either healthy or at risk/diagnosed with psychopathology. Within these groups, we assessed the impact of social engagement and disengagement tasks on HRV. Results Results showed that social engagement tasks left HRV unaltered to a baseline. Social disengagement, however, was associated with decreases in HRV. In a task that included disengagement and then engagement, HRV was reduced during disengagement but was then restored during the reunion phase (engagement). Children at risk or with a diagnosis for psychopathology, however, failed to show any change in HRV during dyadic social interaction tasks. This was despite a social stressor, the Trier Social Stress Test, causing significantly reduced HRV in both groups. Conclusions This meta-analysis provides support to suggest HRV may provide a worthwhile context specific marker for the effective regulation of dyadic social interactions in children.

Social perception in children born at very low birthweight and its relationship with social/behavioral outcomes / Kathryn E. WILLIAMSON in Journal of Child Psychology and Psychiatry, 55-9 (September 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-9 (September 2014) . - p.990-998 Titre : Social perception in children born at very low birthweight and its relationship with social/behavioral outcomes Type de document : Texte imprimé et/ou numérique Auteurs : Kathryn E.

Methods To gain insight into core deficits that may underlie these difficulties, in this study, we assessed the social perceptual skills of 8- to 11-year-old children born at very low birthweight (VLBW) (1,500 g) and age-matched, full-term controls, using the Child and Adolescent Social Perception Measure. We also assessed social and behavioral outcomes with two parent-report measures used in ASD screening. Results Children in the preterm group had normal range estimated verbal IQ. However, we found that they were impaired in their ability to use nonverbal cues from moving faces and bodies, and situational cues, to correctly identify the emotions of characters depicted in videotaped social interactions. Their performance on this task was related to the number of ‘autistic-like’ traits they displayed. Conclusions This research highlights links between social perceptual deficits and poor social and behavioral outcomes in children born very prematurely. The results also suggest that even those who have escaped major intellectual/language problems are at risk for social and behavioral problems that can be of clinical concern.

If similar processes operate in human development then this is significant, as the capacity to regulate emotional states is fundamental to human adaptation. Methods We utilised a 22-year longitudinal study to examine the influence of early infant attachment to the mother, a key marker of early experience, on neural regulation of emotional states in young adults. Infant attachment status was measured via objective assessment at 18-months, and the neural underpinnings of the active regulation of affect were studied using fMRI at age 22 years. Results Infant attachment status at 18-months predicted neural responding during the regulation of positive affect 20-years later. Specifically, while attempting to up-regulate positive emotions, adults who had been insecurely versus securely attached as infants showed greater activation in prefrontal regions involved in cognitive control and reduced co-activation of nucleus accumbens with prefrontal cortex, consistent with relative inefficiency in the neural regulation of positive affect. Conclusions Disturbances in the mother–infant relationship may persistently alter the neural circuitry of emotion regulation, with potential implications for adjustment in adulthood.

A second goal was to examine differences in pupil dilation to emotional stimuli between children of anxious versus nonanxious mothers. Method Participants included 117 mother–child pairs drawn from the community. Children were between the ages of 8 and 14. Pupil dilation was assessed using an eye-tracker while participants viewed angry, happy, or sad faces. Results Children of mothers with a history of major depression (MDD) exhibited increased pupil dilation to sad, but not happy or angry, faces compared with children of nondepressed mothers. Second, we found that children of anxious mothers exhibited increased pupil dilation to angry, but not happy or sad, faces compared to youth of nonanxious mothers. Conclusions The current findings add to the growing body of research suggesting that differences in physiological reactivity to depression- and anxiety-relevant cues may represent an important mechanism in the intergenerational transmission of MDD and anxiety.

Methods Participants were sourced from the Western Australian Pregnancy Cohort (Raine) Study that includes 2868 children born between 1989 and 1992 in Perth, Western Australia. When the children were 17 years old (2006–2009), cognitive performance was assessed using a computerized cognitive battery of tests (CogState) that included six tasks. Using a food frequency questionnaire administered when the children were 14 years old (2003–2006), ‘Healthy’ and ‘Western’ dietary patterns were identified by factor analysis. Associations between dietary patterns at 14 years of age and cognitive performance at 17 years of age were assessed prospectively using multivariate regression models. Results Dietary and cognitive performance data were available for 602 participants. Following adjustment for the ‘Healthy’ dietary pattern, total energy intake, maternal education, family income, father's presence in the family, family functioning and gender, we found that a longer reaction time in the detection task (? = .016; 95% CI: 0.004; 0.028; p = .009) and a higher number of total errors in the Groton Maze Learning Test – delayed recall task (? = .060; 95% CI: 0.006; 0.114; p = .029) were significantly associated with higher scores on the ‘Western’ dietary pattern. The ‘Western’ dietary pattern was characterized by high intakes of take-away food, red and processed meat, soft drink, fried and refined food. We also found that within the dietary patterns, high intake of fried potato, crisps and red meat had negative associations, while increased fruit and leafy green vegetable intake had positive associations with some aspects of cognitive performance. Conclusion Higher dietary intake of the ‘Western’ dietary pattern at age 14 is associated with diminished cognitive performance 3 years later, at 17 years.

Two earlier studies examined the effect of the serotonin transporter polymorphism (5-HTTLPR) on sensitive parenting, but reported opposite results. In a large cohort we further examined whether 5-HTTLPR is a predictor of observed maternal sensitivity and whether observed child social fearfulness moderates the effect of 5-HTTLPR on maternal sensitivity. Methods The population-based cohort consisted of 767 mother–child dyads. Maternal sensitivity was repeatedly observed at the child's age of 14 months, 36 months and 48 months. Sensitivity was coded using the Ainsworth's rating scales for sensitivity and cooperation and the revised Erickson rating scales for Supportive presence and Intrusiveness. Child social fearfulness was observed using the Stranger Approach episode of the Laboratory Temperament Assessment Battery at 36 months. Results Repeated measurement analyses showed a consistent main effect of maternal 5-HTTLPR on sensitivity; mothers carrying the S-allele were more sensitive toward their children (p = .005). This effect was not explained by the child's 5-HTTLPR genotype. We found no evidence that child social fearfulness moderated the effect of 5-HTTLPR on sensitivity. Conclusions This study suggests that variations in maternal 5-HTTLPR genotype appear to be involved in the etiology of parenting behavior. The observed effects of this genetic variation are consistent with the notion that parenting may have a genetic component, but large studies are needed to find the specific small molecular effects.

Two earlier studies examined the effect of the serotonin transporter polymorphism (5-HTTLPR) on sensitive parenting, but reported opposite results. In a large cohort we further examined whether 5-HTTLPR is a predictor of observed maternal sensitivity and whether observed child social fearfulness moderates the effect of 5-HTTLPR on maternal sensitivity.

Genetic and environmental influences on adolescent attachment / Richard M. PASCO FEARON in Journal of Child Psychology and Psychiatry, 55-9 (September 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-9 (September 2014) . - p.1033-1041 Titre : Genetic and environmental influences on adolescent attachment Type de document : Texte imprimé et/ou numérique Auteurs : Richard M. PASCO FEARON, Auteur ; Yael SHMUELI-GOETZ, Auteur ; Essi VIDING, Auteur ; Peter FONAGY, Auteur ; Robert PLOMIN, Auteur Article en page(s) : p.1033-1041 Langues : Anglais (eng) Mots-clés : Adolescence  attachment  genetics  environmental influences Index. décimale : PER Périodiques Résumé : Background Twin studies consistently point to limited genetic influence on attachment security in the infancy period, but no study has examined whether this remains the case in later development. This study presents the findings from a twin study examining the relative importance of genetic and environmental influences on attachment in adolescence. Methods The sample included 551 twin pairs aged 15 years recruited from the larger Twins Early Development Study (TEDS). Attachment was assessed using a semistructured interview, the Child Attachment Interview. Results We found robust associations between MZ twins' scores for Coherence and their overall security of attachment (r = .42, p .001; kappa = .26, p .001), but substantially lower associations for DZ twins (r = .20, p = .001; kappa = .09, p = .20), suggesting genetic influence on adolescent attachment (and substantial nonshared environment). Model-fitting analyses confirmed this impression, indicating approximately 40% heritability of attachment and negligible influence of the shared environment. Conclusions The results suggest that genes may play an important role in adolescent attachment and point to the potentially distinct aetiological mechanisms involved in individual differences in attachment beyond early childhood.

Prevalence and predictors of PTSD and depression among adolescent victims of the Spring 2011 tornado outbreak / Zachary W. ADAMS in Journal of Child Psychology and Psychiatry, 55-9 (September 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-9 (September 2014) . - p.1047-1055 Titre : Prevalence and predictors of PTSD and depression among adolescent victims of the Spring 2011 tornado outbreak Type de document : Texte imprimé et/ou numérique Auteurs : Zachary W.

RUGGIERO, Auteur Article en page(s) : p.1047-1055 Langues : Anglais (eng) Mots-clés : Disaster  adolescents  PTSD  depression  tornadoes Index. décimale : PER Périodiques Résumé : Background Relatively few studies have examined prevalence and predictors of posttraumatic stress disorder (PTSD) or major depressive episode (MDE) in disaster-affected adolescents. Fewer still have administered diagnostic measures or studied samples exposed to tornadoes, a common type of disaster. Further, methodologic problems limit the generalizability of previous findings. This study addressed prevalence estimates and risk factors for PTSD and MDE among adolescents exposed to the Spring 2011 tornado outbreak in Alabama and Joplin, Missouri. Methods A large (N = 2000), population-based sample of adolescents and caregivers, recruited randomly from tornado-affected communities, participated in structured telephone interviews. PTSD and MDE prevalence were estimated for the overall sample, by gender, and by age. Hierarchical logistic regression was used to identify risk factors for PTSD and MDE. Results Overall, 6.7% of adolescents met diagnostic criteria for PTSD and 7.5% of adolescents met diagnostic criteria for MDE since the tornado. Girls were significantly more likely than boys to meet diagnostic criteria for MDE, and older adolescents were more likely than younger adolescents to report MDE since the tornado. Female gender, prior trauma exposure, and an injured family member were associated with greater risk for PTSD and MDE. Specific incident characteristics (loss of services, concern about others’ safety) were associated with greater PTSD risk; prior disaster exposure was associated with lower MDE risk. Conclusions However, most adolescents were resilient following tornado exposure, roughly 1 in 15 developed PTSD, 1 in 13 developed MDE, and many more endorsed subclinical mental health problems. Information regarding specific risk factors can guide early screening, prevention, and intervention efforts in disaster-affected communities.

Who is afraid of math? Two sources of genetic variance for mathematical anxiety / Zhe WANG in Journal of Child Psychology and Psychiatry, 55-9 (September 2014)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 55-9 (September 2014) . - p.1056-1064 Titre : Who is afraid of math?

In particular, mathematical anxiety has attracted recent attention because of its damaging psychological effects and potential associations with mathematical problem solving and achievement. This study investigated the genetic and environmental factors contributing to the observed differences in the anxiety people feel when confronted with mathematical tasks. In addition, the genetic and environmental mechanisms that link mathematical anxiety with math cognition and general anxiety were also explored. Methods Univariate and multivariate quantitative genetic models were conducted in a sample of 514 12-year-old twin siblings. Results Genetic factors accounted for roughly 40% of the variation in mathematical anxiety, with the remaining being accounted for by child-specific environmental factors. Multivariate genetic analyses suggested that mathematical anxiety was influenced by the genetic and nonfamilial environmental risk factors associated with general anxiety and additional independent genetic influences associated with math-based problem solving. Conclusions The development of mathematical anxiety may involve not only exposure to negative experiences with mathematics, but also likely involves genetic risks related to both anxiety and math cognition. These results suggest that integrating cognitive and affective domains may be particularly important for mathematics and may extend to other areas of academic achievement.
