Annual Research Review: Developmental pathways linking early behavioral inhibition to later anxiety / Nathan A. FOX in Journal of Child Psychology and Psychiatry, 64-4 (April 2023)
[article]
Titre : Annual Research Review: Developmental pathways linking early behavioral inhibition to later anxiety Type de document : Texte imprimé et/ou numérique Auteurs : Nathan A. FOX, Auteur ; Selin ZEYTINOGLU, Auteur ; Emilio A. VALADEZ, Auteur ; George A. BUZZELL, Auteur ; Santiago MORALES, Auteur ; Heather A. HENDERSON, Auteur Article en page(s) : p.537-561 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Behavioral Inhibition is a temperament identified in the first years of life that enhances the risk for development of anxiety during late childhood and adolescence. Amongst children characterized with this temperament, only around 40 percent go on to develop anxiety disorders, meaning that more than half of these children do not. Over the past 20?years, research has documented within-child and socio-contextual factors that support differing developmental pathways. This review provides a historical perspective on the research documenting the origins of this temperament, its biological correlates, and the factors that enhance or mitigate risk for development of anxiety. We review as well, research findings from two longitudinal cohorts that have identified moderators of behavioral inhibition in understanding pathways to anxiety. Research on these moderators has led us to develop the Detection and Dual Control (DDC) framework to understand differing developmental trajectories among behaviorally inhibited children. In this review, we use this framework to explain why and how specific cognitive and socio-contextual factors influence differential pathways to anxiety versus resilience.

[article]
Titre : Associations among stress and language and socioemotional development in a low-income sample Type de document : Texte imprimé et/ou numérique Auteurs : Sonya V. TROLLER-RENFREE, Auteur ; Emma R. HART, Auteur ; Jessica F. SPERBER, Auteur ; Nathan A. FOX, Auteur ; Kimberly G. NOBLE, Auteur Article en page(s) : 597-605 Langues : Anglais (eng) Mots-clés : socioeconomic status poverty stress socioemotional language Index. décimale : PER Périodiques Résumé : Stress has been linked with children?s socioemotional problems and lower language scores, particularly among children raised in socioeconomically disadvantaged circumstances. Much of the work examining the relations among stress, language, and socioemotional functioning have relied on assessments of a single dimension of maternal stress. However, stress can stem from different sources, and people may appraise stressors differently. Taking a dimensional approach, this manuscript characterizes stress in multiple ways: as an overall composite; across the constructs of psychological appraisal vs. environmental stressors; and the independent contributions of a variety assessments. Data are from 548 mother?infant dyads (M = 13.14 months, SD = 2.11) who served as the control group for a poverty reduction clinical trial. Mothers completed questionnaires regarding the different types of stresses they may have experienced, as well as their children?s language and socioemotional development. Results indicate that, collectively, higher maternal report of stress is associated with lower reports of children?s socioemotional and language development. In addition, maternal psychological appraisals of stress were associated with both socioemotional and language development, whereas reports of environmental stressors were only associated with socioemotional development. Together, these findings suggest that maternal reports of stress are associated with lower maternal report of child development among low-income children.

MCLAUGHLIN in Journal of Child Psychology and Psychiatry, 53-1 (January 2012)
[article]
Titre : Attachment security as a mechanism linking foster care placement to improved mental health outcomes in previously institutionalized children Type de document : Texte imprimé et/ou numérique Auteurs : Katie A. MCLAUGHLIN, Auteur ; Charles H. ZEANAH, Auteur ; Nathan A. FOX, Auteur ; Charles A. III NELSON, Auteur Année de publication : 2012 Article en page(s) : p.46-55 Langues : Anglais (eng) Mots-clés : Institutionalization childhood adversity attachment internalizing depression;anxiety Index. décimale : PER Périodiques Résumé : Background: Children reared in institutions experience elevated rates of psychiatric disorders. Inability to form a secure attachment relationship to a primary caregiver is posited to be a central mechanism in this association. We determined whether the ameliorative effect of a foster care (FC) intervention on internalizing disorders in previously institutionalized children was explained by the development of secure attachment among children placed in FC. Second we evaluated the role of lack of attachment in an institutionalized sample on the etiology of internalizing disorders within the context of a randomized trial. Methods: A sample of 136 children (aged 6–30 months) residing in institutions was recruited in Bucharest, Romania. Children were randomized to FC (n = 68) or to care as usual (CAU; n = 68). Foster parents were recruited, trained, and overseen by the investigative team. Attachment security at 42 months was assessed using the Strange Situation Procedure, and internalizing disorders at 54 months were assessed using the Preschool Age Psychiatric Assessment. Results: Girls in FC had fewer internalizing disorders than girls in CAU (OR = 0.17, p = .006). The intervention had no effect on internalizing disorders in boys (OR = 0.47, p = .150). At 42 months, girls in FC were more likely to have secure attachment than girls in CAU (OR = 12.5, p < .001), but no difference was observed in boys (OR = 2.0, p = .205). Greater attachment security predicted lower rates of internalizing disorders in both sexes. Development of attachment security fully mediated intervention effects on internalizing disorders in girls. Conclusion: Placement into FC facilitated the development of secure attachment and prevented the onset of internalizing disorders in institutionalized girls. The differential effects of FC on attachment security in boys and girls explained gender differences in the intervention effects on psychopathology. Findings provide evidence for the critical role of disrupted attachment in the etiology of internalizing disorders in children exposed to institutionalization.

[article]
Titre : Attention bias modification for youth with social anxiety disorder Type de document : Texte imprimé et/ou numérique Auteurs : Lee PERGAMIN-HIGHT, Auteur ; Daniel S. PINE, Auteur ; Nathan A. FOX, Auteur ; Yair BAR-HAIM, Auteur Article en page(s) : p.1317-1325 Langues : Anglais (eng) Mots-clés : Adolescence anxiety attention treatment trials Index. décimale : PER Périodiques Résumé : Background Attention bias modification treatment (ABMT) targets threat-related attention biases in anxiety disorders. Most clinical trials of ABMT have focused on adults or small samples of youth. The current randomized controlled trial (RCT) examines ABMT efficacy in youth with social anxiety disorder (SAD) and tests possible moderators of treatment outcomes. Method Sixty-seven youth with SAD were randomly assigned to ABMT or attention control training (ACT) conditions. Anxiety severity was measured at baseline, posttreatment, and 3-month follow-up. ClinicalTrials.gov name and identifier: Attention bias modification treatment for children with social anxiety, NCT01397032; http://www.clinicaltrials.gov. Results Both ABMT and ACT induced significant reductions in clinician and self-rated social anxiety (ps < .001). An additional reduction was observed at the 3-month follow-up in clinician-rated anxiety symptoms (p = .03). Moderation effects were nonsignificant for the clinician-rated anxiety outcome, but age moderated self-reported anxiety. Older but not younger children, showed significant reduction in anxiety following ABMT relative to ACT (p < .001). Individual differences in attention control also moderated ABMT's effect on self-reported anxiety (p = .05). Children rated by their parents as lower on attention control benefited more from ABMT than those rated higher on attention control. Baseline attention bias did not moderate anxiety (p = .17). Conclusions Despite significant reductions in social anxiety, no specific evidence for ABMT was found relative to a control condition. Age and attention control moderated ABMT effects on self-reported SAD symptoms, with clinical effects for older relative to younger children and for those with lower attention control. These results highlight the need to consider developmental influences in the implementation of ABMT protocols.

Titre : Attention to novelty in behaviorally inhibited adolescents moderates risk for anxiety Type de document : Texte imprimé et/ou numérique Auteurs : Bethany C. REEB-SUTHERLAND, Auteur ; Nathan A. FOX, Auteur ; Daniel Samuel PINE, Auteur ; Peter J. MARSHALL, Auteur ; Ross E. VANDEWERT, Auteur ; Kathryn A. DEGNAN, Auteur ; Koraly PEREZ-EDGAR, Auteur ; Andrea CHRONIS-TUSCANO, Auteur Année de publication : 2009 Article en page(s) : p.1365-1372 Langues : Anglais (eng) Mots-clés : Temperament anxiety adolescence attention risk-factors Index. décimale : PER Périodiques Résumé : Background: Individual differences in specific components of attention contribute to behavioral reactivity and regulation. Children with the temperament of behavioral inhibition (BI) provide a good context for considering the manner in which certain components of attention shape behavior. Infants and children characterized as behaviorally inhibited manifest signs of heightened orienting to novelty. The current study considers whether this attention profile moderates risk for clinical anxiety disorders among adolescents with a history of BI.
Methods: Participants were assessed at multiple time points for BI, beginning in early childhood. At adolescence, event-related potentials (ERPs) were recorded during a three-stimulus auditory novelty oddball task, which employed frequent standard and infrequent deviant tones as well as a set of complex, novel sounds. Clinical diagnosis was carried out using the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL). P3 and mismatch negativity (MMN) components were examined at midline frontal, central, and parietal electrode sites.
Results: Individuals who displayed high levels of BI during childhood and increased P3 amplitude to novelty in adolescence were more likely to have a history of anxiety disorders compared to behaviorally inhibited adolescents with lower P3 amplitudes. Groups did not differ on measures of MMN.
Conclusions: Increased neural responses to novelty moderate risk for anxiety disorders amongst individuals with a history of BI.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2009.02170.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=848
