Charting the trajectories of adopted children's emotional and behavioral problems: The impact of early adversity and postadoptive parental warmth / Amy L. PAINE in Development and Psychopathology, 33-3 (August 2021)

SHELTON, Auteur Article en page(s) : p.922-936 Langues : Anglais (eng) Mots-clés : adoption  externalizing  internalizing  warm parenting Index. décimale : PER Périodiques Résumé : Children who are adopted from care are more likely to experience enduring emotional and behavioral problems across development; however, adoptees’ trajectories of mental health problems and factors that impact their trajectories are poorly understood. Therefore, we used multilevel growth analyses to chart adoptees’ internalizing and externalizing problems across childhood, and examined the associations between preadoptive risk and postadoptive protective factors on their trajectories. This was investigated in a prospective longitudinal study of case file records (N = 374) and questionnaire-based follow-ups (N = 96) at approximately 5, 21, and 36 months postadoptive placement. Preadoptive adversity (indexed by age at placement, days in care, and number of adverse childhood experiences) was associated with higher internalizing and externalizing scores; the decrease in internalizing scores over childhood was accelerated for those exposed to lower levels of preadoptive risk. Warm adoptive parenting was associated with a marked reduction in children's internalizing and externalizing problems over time. Although potentially limited by shared methods variance and lack of variability in parental warmth scores, these findings demonstrate the deleterious impact of preadoptive risk and the positive role of exceptionally warm adoptive parenting on children's trajectories of mental health problems and have relevance for prevention and intervention strategies.

Continuity and change in anger and aggressiveness from infancy to childhood: The protective effects of positive parenting / Oliver PERRA in Development and Psychopathology, 33-3 (August 2021)  

Public ISBD [article]  inDevelopment and Psychopathology > 33-3 (August 2021) . - p.937-956 Titre : Continuity and change in anger and aggressiveness from infancy to childhood: The protective effects of positive parenting Type de document : Texte imprimé et/ou numérique Auteurs : Oliver PERRA, Auteur ; Amy L. PAINE, Auteur ; Dale F. HAY, Auteur Article en page(s) : p.937-956 Langues : Anglais (eng) Mots-clés : aggressive conduct problems  conduct disorder  person-centered analyses  oppositional defiant disorder  positive parenting Index. décimale : PER Périodiques Résumé : Early signs of anger and aggression can be identified in infancy. Our aim was to use person-centered methods to identify which infants were most at risk for clinically significant behavioral problems by age 3 and diagnoses of ODD/CD by 7 years, while considering the role of family risk factors and positive parenting. A representative British community sample of 304 infants was assessed by multiple informants at mean ages of 6, 21, and 36 months of age. Latent Transition Analysis (LTA) identified three ordered subgroups at each age, with one subgroup (18%) displaying high levels of physical force as well as anger. These angry aggressive infants were at elevated risk for behavioral problems in early childhood and diagnoses of conduct disorder (CD) and/or oppositional defiant disorder (ODD) at 7 years of age. After other risk factors were taken into account, parents' beliefs in warm parenting and their observed positive affect while interacting with their infants were protective factors. These findings indicate the significance of very early manifestations of angry aggressiveness and have relevance for developmental theories of aggression and prevention strategies.

Does mothers’ postnatal depression influence the development of imitation? / Oliver PERRA in Journal of Child Psychology and Psychiatry, 56-11 (November 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-11 (November 2015) . - p.1231-1238 Titre : Does mothers’ postnatal depression influence the development of imitation? Type de document : Texte imprimé et/ou numérique Auteurs : Oliver PERRA, Auteur ; Rebecca PHILLIPS, Auteur ; Rhiannon FYFIELD, Auteur ; Cerith S. WATERS, Auteur ; Dale F. HAY, Auteur Article en page(s) : p.1231-1238 Langues : Anglais (eng) Mots-clés : Learning  infancy  postnatal  maternal depression Index. décimale : PER Périodiques Résumé : Background Links between mothers’ postnatal depression (PND) and children's cognition have been identified in several samples, but the evidence is inconsistent. We hypothesized that PND may specifically interfere with infants’ imitation, an early learning ability that features in early mother–infant interaction and is linked to memory, causal understanding and joint attention. Methods A randomly controlled experiment on imitation was embedded into a longitudinal study of a representative sample of firstborn British infants, whose mothers were assessed for depression using the SCAN interview during pregnancy and at 6 months postpartum. At a mean of 12.8 months, 253 infants were presented with two imitation tasks that varied in difficulty, in counterbalanced order. Results The infants of mothers who experienced PND were significantly less likely than other infants in the sample to imitate the modelled actions, showing a 72% reduction in the likelihood of imitation. The association with PND was not explained by sociodemographic adversity, or a history of depression during pregnancy or prior to conception. Mothers’ references to infants’ internal states during mother–infant interaction at 6 months facilitated imitation at 12 months, but did not explain the link with PND. Conclusions The findings support the hypothesis that associations between PND and later cognitive outcomes may partly derive from effects of the mother's illness on infants’ early learning abilities. Support for infants’ learning should be considered as an age-appropriate, child-focused component of interventions designed to ameliorate the effects of PND.

Imitation and ‘theory of mind’ competencies in discrimination of autism from other neurodevelopmental disorders / Oliver PERRA in Research in Autism Spectrum Disorders, 2-3 (July / September 2008)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 2-3 (July / September 2008) . - p.456-468 Titre : Imitation and ‘theory of mind’ competencies in discrimination of autism from other neurodevelopmental disorders Type de document : Texte imprimé et/ou numérique Auteurs : Oliver PERRA, Auteur ; David I. PERRETT, Auteur ; Justin H.G. WILLIAMS, Auteur ; Andrew WHITEN, Auteur ; Lesley FRASER, Auteur ; Helen BENZIE, Auteur Année de publication : 2008 Article en page(s) : p.456-468 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Several studies have reported imitative deficits in autism spectrum disorder (ASD). However, it is still debated if imitative deficits are specific to ASD or shared with clinical groups with similar mental impairment and motor difficulties. We investigated whether imitative tasks can be used to discriminate ASD children from typically developing children (TD) and children with general developmental delay (GDD). We applied discriminant function analyses to the performance of these groups on three imitation tasks and tests of dexterity, motor planning, verbal skills, theory of mind (ToM). Analyses revealed two significant dimensions. The first represented impairment of dexterity and verbal ability, and discriminated TD from GDD children. Once these differences were accounted for, differences in ToM and the three imitation tasks accounted for a significant proportion of the remaining intergroup variance and discriminated the ASD group from other groups. Further analyses revealed that inclusion of imitative tasks increased the specificity and sensitivity of ASD classification and that imitative tasks considered alone were able to reliably discriminate ASD, TD and GDD. The results suggest that imitation and theory of mind impairment in autism may stem from a common domain of origin separate from general cognitive and motor skill.
