Neural reactivity to monetary rewards and losses differentiates social from generalized anxiety in children / Ellen M. KESSEL in Journal of Child Psychology and Psychiatry, 56-7 (July 2015)
[article]
Titre : Neural reactivity to monetary rewards and losses differentiates social from generalized anxiety in children Type de document : Texte imprimé et/ou numérique Auteurs : Ellen M. KESSEL, Auteur ; Autumn KUJAWA, Auteur ; Greg HAJCAK PROUDFIT, Auteur ; Daniel N. KLEIN, Auteur Article en page(s) : p.792-800 Langues : Anglais (eng) Mots-clés : Anxiety reward processing children event-related potentials Index. décimale : PER Périodiques Résumé : Background The relationship between reward sensitivity and pediatric anxiety is poorly understood. Evidence suggests that alterations in reward processing are more characteristic of depressive than anxiety disorders. However, some studies have reported that anxiety disorders are also associated with perturbations in reward processing. Heterogeneity in the forms of anxiety studied may account for the differences between studies. We used the feedback-negativity, an event-related potential sensitive to monetary gains versus losses (?FN), to examine whether different forms of youth anxiety symptoms were uniquely associated with reward sensitivity as indexed by neural reactivity to the receipt of positive and negative monetary outcomes. Method Participants were 390, eight- to ten-year-old children (175 females) from a large community sample. The ?FN was measured during a monetary reward task. Self-reports of child anxiety and depression symptoms and temperamental positive emotionality (PE) were obtained. Results Multiple regression analysis revealed that social anxiety and generalized anxiety symptoms were unique predictors of reward sensitivity after accounting for concurrent depressive symptoms and PE. While social anxiety was associated with a greater ?FN, generalized anxiety was associated with a reduced ?FN. Conclusions Different symptom dimensions of child anxiety are differentially related to alterations in reward sensitivity. This may, in part, explain inconsistent findings in the literature regarding reward processing in anxiety.
