Confirming the etiology of adolescent acting-out behaviors: an examination of observer-ratings in a sample of adoptive and biological siblings / S. Alexandra BURT in Journal of Child Psychology and Psychiatry, 52-5 (May 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-5 (May 2011) . - p.519-526 Titre : Confirming the etiology of adolescent acting-out behaviors: an examination of observer-ratings in a sample of adoptive and biological siblings Type de document : Texte imprimé et/ou numérique Auteurs : S. Alexandra BURT, Auteur ; Ashlea M. KLAHR, Auteur ; Martha A. RUETER, Auteur ; Matt MCGUE, Auteur ; William G. IACONO, Auteur Année de publication : 2011 Article en page(s) : p.519-526 Langues : Anglais (eng) Mots-clés : Shared environment  antisocial behavior  adoption design  observer-ratings Index. décimale : PER Périodiques Résumé : Background:  A recent meta-analysis revealed moderate shared environmental influences (C) on most forms of child and adolescent psychopathology (Burt, 2009), including antisocial behavior. Critically, however, the research analyzed in this meta-analysis relied largely on specific informant-reports (and particularly parent and child reports), each of which is subject to various sources of rater bias. Observer-ratings of children’s behaviors avoid many of these biases, and are thus well suited to verify the presence of C. Given this, we sought to buttress the evidence supporting C in two key ways. First, we sought to confirm that C contributes to observer-ratings in a sample of adoptive siblings, as similarity between adoptive siblings constitutes a ‘direct’ estimate of C. Second, we sought to confirm that these shared environmental influences persist across informants (i.e., the effects are not specific to the rater or the context in question). Methods:  The current study examined the etiology of observer-ratings of acting-out behaviors, as well as sources of etiological overlap across observer-ratings, adolescent self-report and maternal-report in sample of over 600 biological and adoptive sibling pairs from the Sibling Interaction and Behavior Study (SIBS). Results:  Results revealed moderate and significant shared environmental influences on observer-ratings (31%), as well as on the other informant-reports (20–23%). Moreover, a portion of these effects overlapped across measures (C correlations ranged from .32 to .34). Conclusions:  Such findings argue against passive gene–environment correlations (rGE) and rater bias as primary explanations for earlier findings of C on antisocial behavior, and in this way, offer a critical extension of prior work indicating that the role of shared environmental influences on child and adolescent antisocial behavior was dismissed too soon.

Post-adoption contact, adoption communicative openness, and satisfaction with contact as predictors of externalizing behavior in adolescence and emerging adulthood / Harold D. GROTEVANT in Journal of Child Psychology and Psychiatry, 52-5 (May 2011)

Method:  The study included 190 families of infant-placed, domestic adoptees during childhood, adolescence, and emerging adulthood. Structural equation modeling (SEM) was used to analyze predictors of externalizing behavior from contact (adoptive parents and adolescent reports), adoption communicative openness (adoptive mothers), and satisfaction with contact (adoptive parents and adolescent). Results:  Externalizing behavior showed moderate stability across childhood, adolescence, and emerging adulthood. Contact and adoption communicative openness were related to each other, but not to externalizing behaviors in adolescence or emerging adulthood. Controlling for the effect of Childhood Externalizing, adoptive families most satisfied with contact reported relative declines in adoptee externalizing behavior during adolescence compared to those in less satisfied families. Satisfaction was also indirectly associated with Emerging Adult Externalizing, through its effect on Adolescent Externalizing. Conclusions:  Although contact and adoption communicative openness were highly correlated with each other, neither was related to adoptees’ externalizing behavior in adolescence or emerging adulthood. Family-level satisfaction with contact was more predictive of externalizing outcomes.

Parent ratings of executive functioning in children adopted from psychosocially depriving institutions / Emily C. MERZ in Journal of Child Psychology and Psychiatry, 52-5 (May 2011)

Methods:  Parent ratings of EF were examined in 288 school-age and 130 preschool-age children adopted from psychosocially depriving Russian institutions that provided adequate physical resources but not one-on-one interactions with a consistent set of responsive caregivers. Results:  Results revealed a step-like association between age at adoption and EF deficits; school-age children adopted after 18 months of age had greater EF difficulties than younger-adopted children and the never-institutionalized normative sample. The onset of adolescence was associated with a greater increase in EF deficits for children adopted after 18 months than for younger-adopted children. Preschool-age children were not found to have greater EF difficulties than the normative sample. Conclusions:  These findings suggest that prolonged early psychosocial deprivation may increase children’s risk of EF deficits and that the developmental stresses of adolescence may be particularly challenging for older-adopted PI children.

Methods:  A structural equation model (SEM) of multiple cognitive risk factors and symptom outcome variables was constructed. The model included phonological awareness as a unique predictor of RD and response inhibition as a unique predictor of ADHD. Processing speed, naming speed, and verbal working memory were modeled as potential shared cognitive deficits. Results:  Model fit indices from the SEM indicated satisfactory fit. Closer inspection of the path weights revealed that processing speed was the only cognitive variable with significant unique relationships to RD and ADHD dimensions, particularly inattention. Moreover, the significant correlation between reading and inattention was reduced to non-significance when processing speed was included in the model, suggesting that processing speed primarily accounted for the phenotypic correlation (or comorbidity) between reading and inattention. Conclusions:  This study illustrates the power of a multiple deficit approach to complex developmental disorders and psychopathologies, particularly for exploring comorbidities. The theoretical role of processing speed in the developmental pathways of RD and ADHD and directions for future research are discussed.

The nature of trauma memories in acute stress disorder in children and adolescents / Claire H. SALMOND in Journal of Child Psychology and Psychiatry, 52-5 (May 2011)

However, research into the phenomenology of trauma memories in young people is currently scarce. Methods:  This study compared the nature of trauma narratives to narratives of unpleasant non-traumatic events in young people (aged 8–17) who sought emergency medical attention following an assault or road traffic accident. Data were collected within 2–4 weeks of the index event. Symptom severity was assessed by child self-report and face-to-face diagnostic interviews. Comparisons of narrative indices were made between those children with acute stress disorder (ASD) and those without ASD. Results:  Among participants (n = 50), those with ASD (38%) had significantly elevated levels of disorganisation in their trauma narrative, compared both to trauma-exposed controls and to their unpleasant comparative narrative. This effect was not accounted for by age. Regardless of ASD diagnostic status, trauma narratives had significantly higher sensory content and significantly lower positive emotion content compared to the unpleasant comparative narrative. These effects were not significant when age was included as a covariate. Acute symptom severity was significantly predicted by the level of disorganisation in the trauma narrative and the child’s cognitive appraisals of the event. Conclusions:  These data provide the first empirical evidence that disorganisation is not only directly linked to symptom severity, but also specific to the trauma memory. In addition, it provides support for the adaptation of adult cognitive models to acute pathological stress reactions in children and adolescents.

Mothers’ reports of play dates and observation of school playground behavior of children having high-functioning autism spectrum disorders / Frederick D. FRANKEL in Journal of Child Psychology and Psychiatry, 52-5 (May 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-5 (May 2011) . - p.571-579 Titre : Mothers’ reports of play dates and observation of school playground behavior of children having high-functioning autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Frederick D. FRANKEL, Auteur ; Clarissa M. GOROSPE, Auteur ; Ya-Chih CHANG, Auteur ; Catherine SUGAR, Auteur Année de publication : 2011 Article en page(s) : p.571-579 Langues : Anglais (eng) Mots-clés : Social skills  autism  Asperger’s disorder  friendship Index. décimale : PER Périodiques Résumé : Background:  Children with high-functioning autism spectrum disorders (ASD) are generally included with typically developing peers at school. They have difficulties interacting with peers on the school playground. Previous literature suggests that having play dates in the home may be related to better peer acceptance at school. Methods:  This study examines the relationship between mother-reported play date frequency and amount of conflict, and peer interaction observed on the school playground for a sample of 27 boys and 4 girls meeting structured interview and observation criteria for ASD. Measures of intellectual functioning, adaptive behavior, and social skills were included in a stepwise regression analysis to account for their impact on relationships between maternal play date reports, general peer acceptance at school (as rated by the child’s teacher) and observations of school playground behavior. Results:  Results revealed that children with autism spectrum disorders who had more play dates in their home tended to spend a greater amount of time engaged in behaviors such as mutual offering of objects, conversing and other turn-taking activities with peers on the school playground. They also received more positive responses to their overtures from peers. These relationships remained highly significant even after accounting for other demographic, general social, and cognitive variables. Conclusions:  The present results suggest that play date frequency is strongly related to school playground behavior. Owing to the design of this study, future research must assess whether play dates in the home promote better peer relationships on the playground or the reverse. In either case, the assessment of play dates, as well as observation of spontaneous unsupervised social interactions, are important outcome measures to consider in social skills interventions for children with high-functioning ASD.

Measures of intellectual functioning, adaptive behavior, and social skills were included in a stepwise regression analysis to account for their impact on relationships between maternal play date reports, general peer acceptance at school (as rated by the child’s teacher) and observations of school playground behavior. Results:  Results revealed that children with autism spectrum disorders who had more play dates in their home tended to spend a greater amount of time engaged in behaviors such as mutual offering of objects, conversing and other turn-taking activities with peers on the school playground. They also received more positive responses to their overtures from peers. These relationships remained highly significant even after accounting for other demographic, general social, and cognitive variables. Conclusions:  The present results suggest that play date frequency is strongly related to school playground behavior. Owing to the design of this study, future research must assess whether play dates in the home promote better peer relationships on the playground or the reverse. In either case, the assessment of play dates, as well as observation of spontaneous unsupervised social interactions, are important outcome measures to consider in social skills interventions for children with high-functioning ASD.

TPH2 G/T polymorphism is associated with hyperphagia, IQ, and internalizing problems in Prader–Willi syndrome / Elisabeth M. DYKENS in Journal of Child Psychology and Psychiatry, 52-5 (May 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-5 (May 2011) . - p.580-587 Titre : TPH2 G/T polymorphism is associated with hyperphagia, IQ, and internalizing problems in Prader–Willi syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Elisabeth M.

BUTLER, Auteur Année de publication : 2011 Article en page(s) : p.580-587 Langues : Anglais (eng) Mots-clés : Behavior problems  genetics  intelligence  internalizing disorder  neurochemistry  Prader–Willi syndrome Index. décimale : PER Périodiques Résumé : Background:  Prader–Willi syndrome (PWS) is a genetic, neurodevelopmental disorder characterized by intellectual disabilities, growth hormone dysregulation, hyperphagia, increased risks of morbid obesity, compulsive behaviors, and irritability. As aberrant serotonergic functioning is strongly implicated in PWS, we examined associations between the PWS phenotype and polymorphisms in tryptophan hydroxylase 2 (TPH2), the rate-limiting enzyme in the biosynthesis of serotonin in the brain. Methods:  Ninety-two individuals with PWS aged 4 to 50 years (M = 21.97) were genotyped for the TPH2 G703-T polymorphism. IQ testing was conducted in offspring, and parents completed questionnaires that tapped their child’s compulsivity, hyperphagia, and other behavior problems. Results:  As expected, the frequency of G/T or T/T polymorphisms in participants with PWS (39%) was similar to rates found in the general population (38%). Compared to those with a homozygous (G/G) genotype, individuals with a T allele had significantly higher hyperphagic behavior, drive, and severity scores, and they also had a younger age of onset of hyperphagia. Those with a T allele also had higher IQ scores than their counterparts. Females with a T allele had significantly higher internalizing symptoms, primarily anxiety and depression, than all others. Conclusions:  TPH2 G/T polymorphisms, and presumed loss of enzyme function, were associated with specific aspects of the PWS phenotype. Aberrant serotonergic functioning is strongly implicated in hyperphagia in PWS, and females with TPH2 T alleles may be at higher risk for affective or mood disorders. Findings hold promise for examining other serotonin-altering genes in PWS, and for future serotonin-altering treatment trials.

Language development is usually delayed in children with ASD. The present study examines the development of pre-speech vocal behavior in infants at risk for ASD due to the presence of an older sibling with the disorder. Methods:  Infants at high risk (HR) for ASD and those at low risk, without a diagnosed sibling (LR), were seen at 6, 9, and 12 months as part of a larger prospective study of risk for ASD in infant siblings. Standard clinical assessments were administered, and vocalization samples were collected during play with mother and a standard set of toys. Infant vocal behavior was recorded and analyzed for consonant inventory, presence of canonical syllables, and of non-speech vocalizations, in a cross-sectional design. Children were seen again at 24 months for provisional diagnosis. Results:  Differences were seen between risk groups for certain vocal behaviors. Differences in vocal production in the first year of life were associated with outcomes in terms of autistic symptomotology in the second year. Conclusions:  Early vocal behavior is a sensitive indicator of heightened risk for autistic symptoms in infants with a family history of ASD.

We tested the relative weight that children in general, and high versus low socially anxious children in particular, put on fathers’ versus mothers’ signal about whether a social situation is safe or a threat. Method:  Children aged 8–12 (n = 144) varying in social anxiety were presented scripts of ambiguous social situations in which either the father or the mother acted anxious or confident. Children indicated how anxious or confident they would be. Results:  Fathers’ behaviour influenced high socially anxious children’s confidence or anxiety more than mothers’ behaviour. In contrast, in normal and low socially anxious children, mothers’ behaviour was more influential than fathers’. Conclusions:  Mothers might have the role of teaching social wariness to their low socially anxious children, whereas fathers may teach social confidence to socially anxious children.

Genetic risk by experience interaction for childhood internalizing problems: converging evidence across multiple methods / Matthew VENDLINSKI in Journal of Child Psychology and Psychiatry, 52-5 (May 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-5 (May 2011) . - p.607-618 Titre : Genetic risk by experience interaction for childhood internalizing problems: converging evidence across multiple methods Type de document : Texte imprimé et/ou numérique Auteurs : Matthew VENDLINSKI, Auteur ; Kathryn LEMERY-CHALFANT, Auteur ; Marilyn J.

Few studies have examined genetic risk by experience interaction (G×E) in the development of childhood psychopathology. Methods:  We used both co-twin and parent mental health as markers of genetic risk to test whether G×E predicted internalizing problems in a sample of 8-year-old twins. Multi-instrument composites were used to characterize both parent and child psychopathology, and five experiential risk factors (socioeconomic status, single parent upbringing, negative parent–child interactions, number of negative life events, negative impact of negative life events) composed a cumulative risk index. Results:  We found consistent evidence for G×E for child internalizing problems, with significant interaction effects emerging both when genetic risk was indexed by co-twin mental health and when it was based on parent mental health. When co-twin mental health was used to estimate genetic risk, child internalizing problems were more heritable for children at low rather than high experiential risk. When parent mental health was used to estimate genetic risk, the association between genetic risk and internalizing problems was stronger for children at elevated experiential risk. Consideration of the interaction effect sizes helps to reconcile these findings. Conclusions:  Our results suggest that the processes involved in both diathesis-stress and bioecological models of development may operate for child internalizing problems. Effect sizes indicated that the main effects of genetic and experiential risk were much better predictors of child internalizing problems than was their interaction.

Cumulative-genetic plasticity, parenting and adolescent self-regulation / Jay BELSKY in Journal of Child Psychology and Psychiatry, 52-5 (May 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-5 (May 2011) . - p.619-626 Titre : Cumulative-genetic plasticity, parenting and adolescent self-regulation Type de document : Texte imprimé et/ou numérique Auteurs : Jay BELSKY, Auteur ; Kevin M. BEAVER, Auteur Année de publication : 2011 Article en page(s) : p.619-626 Langues : Anglais (eng) Mots-clés : Self-control  self-regulation  plasticity  G×E  parenting Index. décimale : PER Périodiques Résumé : Background:  The capacity to control or regulate one’s emotions, cognitions and behavior is central to competent functioning, with limitations in these abilities associated with developmental problems. Parenting appears to influence such self-regulation. Here the differential-susceptibility hypothesis is tested that the more putative ‘plasticity alleles’ adolescents carry, the more positively and negatively influenced they will be by, respectively, supportive and unsupportive parenting. Methods:  One thousand, five hundred and eighty-six (1586) adolescents (n = 754 males; n = 832 females) enrolled in the American Add Health project were scored in terms of how many of 5 putative ‘plasticity alleles’ they carried – the 10R allele of DAT1, the A1 allele of DRD2, the 7R allele of DRD4, the short allele of 5HTTLPR, and the 2R/3R alleles of MAOA. Then the effect of the resultant index (ranging from 0 to 5) of cumulative-genetic plasticity in moderating effects of parenting on adolescent self-regulation was evaluated. Results:  Consistent with differential susceptibility, the more plasticity alleles males (but not females) carried, the more and less self-regulation they manifested under, respectively, supportive and unsupportive parenting conditions. Conclusion:  Adolescent males appear to vary for genetic reasons in their susceptibility to parenting vis-à-vis self-regulation, perhaps due to epistatic and/or epigenetic processes. G×E research may benefit from compositing candidate genes. To afford comparative evaluation of differential-susceptibility vs. diathesis-stress models of environmental action, future G×E work should focus on positive as well as negative environmental conditions and developmental outcomes.
