In this paper, we focus on caregiving-related early adversities (crEAs) and parse the heterogeneity of crEAs via data reduction techniques that identify experiential cooccurrences. Using network science, we characterized crEA cooccurrences to represent the comorbidity of crEA experiences across a sample of school-age children (n = 258; 6 12 years old) with a history of crEAs. crEA dimensions (variable level) and crEA subtypes (subject level) were identified using parallel factor analysis/principal component analysis and graph-based Louvain community detection. Bagging enhancement with cross-validation provided estimates of robustness. These data-driven dimensions/subtypes showed evidence of stability, transcended traditional sociolegally defined groups, were more homogenous than sociolegally defined groups, and reduced statistical correlations with sociodemographic factors. Finally, random forests showed both unique and common predictive importance of the crEA dimensions/subtypes for childhood mental health symptoms and academic skills. These data-driven outcomes provide additional tools and recommendations for crEA data reduction to inform precision medicine efforts in this area.

Positive valence bias and parent–child relationship security moderate the association between early institutional caregiving and internalizing symptoms / Michelle R. VANTIEGHEM in Development and Psychopathology, 29-2 (May 2017)  

Public ISBD [article]  inDevelopment and Psychopathology > 29-2 (May 2017) . - p.519-533 Titre : Positive valence bias and parent–child relationship security moderate the association between early institutional caregiving and internalizing symptoms Type de document : texte imprimé Auteurs : Michelle R.

TELZER, Auteur ; Christina CALDERA, Auteur ; Jennifer LOUIE, Auteur ; Mor SHAPIRO, Auteur ; Niall BOLGER, Auteur ; Nim TOTTENHAM, Auteur Article en page(s) : p.519-533 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Institutional caregiving is associated with significant deviations from species-expected caregiving, altering the normative sequence of attachment formation and placing children at risk for long-term emotional difficulties. However, little is known about factors that can promote resilience following early institutional caregiving. In the current study, we investigated how adaptations in affective processing (i.e., positive valence bias) and family-level protective factors (i.e., secure parent–child relationships) moderate risk for internalizing symptoms in previously institutionalized (PI) youth. Children and adolescents with and without a history of institutional care performed a laboratory-based affective processing task and self-reported measures of parent–child relationship security. PI youth were more likely than comparison youth to show positive valence biases when interpreting ambiguous facial expressions. Both positive valence bias and parent–child relationship security moderated the association between institutional care and parent-reported internalizing symptoms, such that greater positive valence bias and more secure parent–child relationships predicted fewer symptoms in PI youth. However, when both factors were tested concurrently, parent–child relationship security more strongly moderated the link between PI status and internalizing symptoms. These findings suggest that both individual-level adaptations in affective processing and family-level factors of secure parent–child relationships may ameliorate risk for internalizing psychopathology following early institutional caregiving.
