Titre : Sympathetic nervous system dominance during stress recovery mediates associations between stress sensitivity and social anxiety symptoms in female adolescents Type de document : Texte imprimé et/ou numérique Auteurs : Tiffany C. HO, Auteur ; Holly T. PHAM, Auteur ; Jonas G. MILLER, Auteur ; Katharina KIRCANSKI, Auteur ; Ian H. GOTLIB, Auteur Article en page(s) : p.1914-1925 Langues : Anglais (eng) Mots-clés : Adolescent Anxiety Autonomic Nervous System Female Heart Rate Humans Male *Respiratory Sinus Arrhythmia Stress, Psychological Sympathetic Nervous System *adolescence *skin conductance level stress *social anxiety disorder Index. décimale : PER Périodiques Résumé : Social anxiety disorder (SAD) is commonly diagnosed during adolescence and is associated with psychological stress reactivity and heightened physiological arousal. No study, however, has systematically examined which aspects of autonomic nervous system function mediate likely links between stress sensitivity and social anxiety symptoms in adolescents. Here, we assessed 163 adolescents (90 females; 12.29 ± 1.39 years) with respect to life stress and social anxiety symptoms, and measured respiratory sinus arrhythmia (RSA) and skin conductance levels (SCL) during a psychosocial stress paradigm. We operationalized stress sensitivity as the residual variance in subjective stress severity after accounting for objective severity and changes in autonomic regulation using standardized change scores in RSA and SCL. In females only, stress sensitivity and social anxiety symptoms were significantly correlated with each other (p < .001) and with autonomic regulation during both reactivity and recovery (all ps < 0.04). Further, sympathetic nervous system dominance during recovery specifically mediated associations between stress sensitivity and social anxiety symptoms (B = 1.06, 95% CI: 0.02-2.64). In contrast, in males, stress sensitivity, autonomic regulation during reactivity or recovery, and social anxiety symptoms were not significantly associated (all ps > 0.1). We interpret these results in the context of psychobiological models of SAD and discuss implications for interventions targeting autonomic processes.
