Salivary cytokine shows elevated communication and interaction fears may heighten neuroendocrine and inflammatory responses
Communication and social interaction anxiety enhance interleukin-1 beta and cortisol reactivity during high-stakes public speaking. Author: Auer BJ, et al (2018), Psychoneuroendocrinology BACKGROUND: Worry or fear related to speaking in front of others, or more broadly, communicating and interacting with others, is common. At elevated levels, however, it may contribute to heightened stress reactivity during acute […]
Research highlights multi-system perspective for motivation, adolescent depressive symptoms, and HPA axis activation
An exploratory analysis of the joint contribution of HPA axis activation and motivation to early adolescent depressive symptoms. Author: Rudolph KD, et al (2018), Developmental Psychobiology BACKGROUND: This study examines the interactive contribution of the hypothalamic-pituitary-adrenal (HPA) axis and approach-avoidance motivation systems to longitudinal changes in depressive symptoms across the adolescent transition. In the summer […]
Testosterone and Proactive-Reactive Aggression in Youth: the Moderating Role of Harsh Discipline. Author: Chen FR, et al (2018), Journal of abnormal child psychology BACKGROUND: This study tests a biosocial model of the link between testosterone and proactive-reactive aggression in youth at varying levels of harsh discipline. Given that proactive aggression is used to gain power […]
Social Context of Psychosocial Processes During Adolescent Development and the Psychobiology of the Stress Response.
Peer Networks, Psychobiology of Stress Response, and Adolescent Development Author: Kornienko, O, et al (2018), PLoS BACKGROUND: A consistent focus of research has been on understanding how social relationships shape the activity of the biological stress response system. Progress has been made in characterizing these dynamics at the level of the individual, but significantly less […]
Anticipatory stress associated with functional magnetic resonance imaging: Implications for psychosocial stress research. Author: Gossett EW, et al (2018), International journal of psychophysiology BACKGROUND: Stress tasks performed during functional magnetic resonance imaging (fMRI) elicit a relatively small cortisol response compared to stress tasks completed in a traditional behavioral laboratory, which may be due to apprehension […]
Attachment – Related Regulatory Processes Moderate the Impact of Adverse Childhood Experiences on Stress Reaction in Borderline Personality Disorder. Author: Ehrenthal JC, et al (2018), Journal of Personality Disorders BACKGROUND: In this study, the authors explored whether attachment insecurity moderates the effects of adverse childhood experiences on stress reactivity in the context of borderline personality […]
Cognitive control moderates parenting stress effects on children’s diurnal cortisol Author: Raffington L, et al (2018), PLoS BACKGROUND: This study investigated associations between parenting stress in parents and self-reported stress in children with children’s diurnal cortisol secretion and whether these associations are moderated by known stress-regulating capacities, namely child cognitive control. Salivary cortisol concentrations were […]
Characterization of the serum and salivary cortisol response to the intravenous 250 µg ACTH1-24 stimulation test Author: Nolan BJ, et al (2018), Endocrine PURPOSE: The ACTH1-24 stimulation test is commonly used to assess the hypothalamic-pituitary-adrenal (HPA) axis. Given variations in CBG concentration and binding affinity, serum total cortisol may misclassify some patients. Salivary cortisol correlates well […]
Emotion regulation and positive affect in the context of salivary alpha-amylase response to pain in children with cancer Author: Jenkins BN, et al (2017), Pediatric Blood & Cancer BACKGROUND: Children with cancer routinely undergo painful medical procedures invoking strong physiological stress responses. Resilience to this pain may be conferred through resources such as emotion regulation […]
