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 […]
Latent Trait Cortisol level reflects accumulation of both distal and recent forms of stress
Individual differences in early adolescents’ latent trait cortisol (LTC): Relation to recent acute and chronic stress. Author: Stroud CB, et al (2016), Psychoneuroendocrinology Research suggests that environmental stress contributes to health by altering the regulation of the hypothalamic pituitary adrenal (HPA) axis. Recent evidence indicates that early life stress alters trait indicators of HPA axis […]
Salivary cortisol and the effects of child care on development in high & low risk contexts
Child Care and Cortisol Across Infancy and Toddlerhood: Poverty, Peers, and Developmental Timing Author: Berry, et al (2016), Family Relations Evidence suggests that relations between child care and children’s development—behaviorally and physiologically—likely differ between children from high- versus low-risk contexts. Using 1,155 participant data from the Family Life Project, the authors tested (a) whether within- […]
Review: How negative parent-child relationships affect the biological stress system
Family relations, stress, and vulnerability: Biobehavioral implications for prevention and practice Author: Ha, et al (2016), Family Relations Developmental psychobiology research supports the hypothesis that individual differences in biological stress systems that are sensitive to environmental experiences are associated with individual adjustment problems. Negative social experiences, especially in family contexts, contribute to the dysregulation of […]
Early adversity contributes to lower latent trait salivary cortisol (LTC) levels in adolescence
Individual differences in early adolescents’ latent trait cortisol (LTC): Relation to early adversity Author: Stroud CB, et al (2016), Developmental Psychobiology Substantial evidence suggests that youth who experience early adversity exhibit alterations in hypothalamic pituitary adrenal (HPA) axis functioning, thereby increasing risk for negative health outcomes. However, few studies have explored whether early adversity alters […]
Longitudinal Salivary Cortisol Study Evaluates Theory of Developmental Origins of Health & Disease
Assessment of the cortisol awakening response: Expert consensus guidelines. Author: Winchester SB, et al (2015). Res Nurs Health. In a prospective, case-controlled longitudinal design, 180 preterm and full-term infants who had been enrolled at birth participated in a comprehensive assessment battery at age 23. Of these, 149 young adults, 34 formerly full-term and 115 formerly […]
