Comparing cortisol, stress, and sensory sensitivity in children with autism / Blythe A. CORBETT in Autism Research, 2-1 (February 2009)  

Public ISBD [article]  inAutism Research > 2-1 (February 2009) . - p.39-49 Titre : Comparing cortisol, stress, and sensory sensitivity in children with autism Type de document : Texte imprimé et/ou numérique Auteurs : Blythe A. CORBETT, Auteur ; Seymour LEVINE, Auteur ; Clayton W. SCHUPP, Auteur ; Sally MENDOZA, Auteur Année de publication : 2009 Article en page(s) : p.39-49 Langues : Anglais (eng) Mots-clés : autism cortisol diurnal-variation stress LHPA sensory-sensitivity Index. décimale : PER Périodiques Résumé : Previously we reported that children with autism show significant variability in cortisol. The current investigation was designed to extend these findings by exploring plausible relationships between cortisol and psychological measures of stress and sensory functioning. Salivary cortisol values for diurnal rhythms and response to stress in children with and without autism were compared to parent-report measures of child stress, the Stress Survey Schedule (SSS), sensory functioning, Short Sensory Profile (SSP), and Parenting Stress Index. In autism, a negative relationship between morning cortisol and the SSS revealed that higher observed symptoms of stress were related to lower cortisol. Lower cortisol is seen in conditions of chronic stress and in social situations characterized by unstable social relationships. Sensory sensitivity painted a more complicated picture, in that some aspects of SSP were associated with higher while others were associated with lower cortisol. We propose that increased sensory sensitivity may enhance the autistic child's susceptibility to the influence of zeitgeibers reflected in variable cortisol secretion. Evening cortisol was positively associated with SSS such that the higher the level of evening cortisol, the higher the child's parent-reported daily stress, especially to changes, such as in daily routine. Regarding the response to stress, the psychological and parent variables did not differentiate the groups; rather, discrete subgroups of cortisol responders and nonresponders were revealed in both the autism and neurotypical children. The results support a complex interplay between physiological and behavioral stress and sensory sensitivity in autism and plausible developmental factors influencing stress reactivity across the groups.

Cortisol and antisocial behavior in early adolescence: The role of gender in an economically disadvantaged sample / Roger KOBAK in Development and Psychopathology, 21-2 (May 2009)  

Public ISBD [article]  inDevelopment and Psychopathology > 21-2 (May 2009) . - p.579-591 Titre : Cortisol and antisocial behavior in early adolescence: The role of gender in an economically disadvantaged sample Type de document : Texte imprimé et/ou numérique Auteurs : Roger KOBAK, Auteur ; Seymour LEVINE, Auteur ; Kristyn ZAJAC, Auteur Année de publication : 2009 Article en page(s) : p.579-591 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This study examines the relation between adolescents' antisocial behaviors and adrenocortical activity during a laboratory visit in a sample of economically disadvantaged families (N = 116, ages 12–14, 51% female). Pretask cortisol levels indexed adolescents' prechallenge response to the lab visit, whereas adolescents' response to a conflict discussion with their caregivers was indexed with residualized change in pre- to postconflict cortisol levels. A trait measure of antisocial behavior (derived from parent, teacher, and self-reports) was associated with lower pretask cortisol levels but greater cortisol response to the conflict discussion. Gender moderated antisocial adolescents' cortisol response to the conflict discussion with girls who reported more covert risky problem behaviors showing an increased cortisol response. The findings suggest that, although antisocial adolescents had lower pretask cortisol levels, conflict discussions with caregivers present a unique challenge to antisocial girls compared with antisocial boys.

Effects of an attachment-based intervention on the cortisol production of infants and toddlers in foster care / Mary DOZIER in Development and Psychopathology, 20-3 (Summer 2008)  

Public ISBD [article]  inDevelopment and Psychopathology > 20-3 (Summer 2008) . - p.845-859 Titre : Effects of an attachment-based intervention on the cortisol production of infants and toddlers in foster care Type de document : Texte imprimé et/ou numérique Auteurs : Mary DOZIER, Auteur ; Jean-Philippe LAURENCEAU, Auteur ; Elizabeth PELOSO, Auteur ; Erin LEWIS, Auteur ; Seymour LEVINE, Auteur Année de publication : 2008 Article en page(s) : p.845-859 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Studies with nonhuman primates and rodents, as well as with human children, have suggested that early separations from caregivers are often associated with changes in the functioning of the hypothalamus–pituitary–adrenal (HPA) axis. On the basis of these findings, we designed a relational intervention that was intended to normalize HPA functioning among children in foster care. This paper presents findings from a randomized clinical trial that assessed the effectiveness of a relational intervention (Attachment and Biobehavioral Catch-up [ABC]) with regard to HPA functioning. The ABC intervention was intended to enhance children's ability to regulate physiology and behavior. The control intervention (Developmental Education for Families) was intended to enhance children's cognitive skills. A comparison group of children who had never been in foster care was also included. Children's cortisol production was assessed upon arrival at the lab, and 15 and 30 min following the Strange Situation. Random effects analyses of variance were performed to assess differences in initial values and change between children in the two intervention groups. Children in the ABC intervention and comparison group children showed lower initial values of cortisol than children in the treatment control group, considering arrival at lab as initial values (p < .05). Groups did not differ significantly in change over time. These results suggest that the ABC intervention is effective in helping children regulate biology in ways more characteristic of children who have not experienced early adversity.
