Allostasis and allostatic load in the context of poverty in early childhood / Clancy BLAIR in Development and Psychopathology, 23-3 (August 2011)

HIBEL, Auteur ; THE FAMILY LIFE PROJECT KEY INVESTIGATORS, Auteur Année de publication : 2011 Article en page(s) : p.845-857 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This paper examined the relation of early environmental adversity associated with poverty to child resting or basal level of cortisol in a prospective longitudinal sample of 1135 children seen at 7, 15, 24, 35, and 48 months of age. We found main effects for poor housing quality, African American ethnicity, and low positive caregiving behavior in which each was uniquely associated with an overall higher level of cortisol from age 7 to 48 months. We also found that two aspects of the early environment in the context of poverty, adult exits from the home and perceived economic insufficiency, were related to salivary cortisol in a time-dependent manner. The effect for the first of these, exits from the home, was consistent with the principle of allostatic load in which the effects of adversity on stress physiology accumulate over time. The effect for perceived economic insufficiency was one in which insufficiency was associated with higher levels of cortisol in infancy but with a typical but steeper decline in cortisol with age at subsequent time points.

Longitudinal effects of maltreatment, intimate partner violence, and Reminiscing and Emotion Training on children's diurnal cortisol regulation / Kristin VALENTINO in Development and Psychopathology, 33-3 (August 2021)  

Public ISBD [article]  inDevelopment and Psychopathology > 33-3 (August 2021) . - p.868-884 Titre : Longitudinal effects of maltreatment, intimate partner violence, and Reminiscing and Emotion Training on children's diurnal cortisol regulation Type de document : Texte imprimé et/ou numérique Auteurs : Kristin VALENTINO, Auteur ; Leah C. HIBEL, Auteur ; Ruth SPEIDEL, Auteur ; Kaitlin FONDREN, Auteur ; Elisa UGARTE, Auteur Article en page(s) : p.868-884 Langues : Anglais (eng) Mots-clés : cortisol  elaboration  intervention  maltreatment  stress physiology Index. décimale : PER Périodiques Résumé : Dysregulation in children's physiological stress systems is a key process linking early adversity to poor health and psychopathology. Thus, interventions that improve children's stress physiology may help prevent deleterious health outcomes. Reminiscing and Emotion Training (RET) is a brief relational intervention designed to improve maternal caregiving support by enhancing maltreating mothers’ capacity to reminisce with their young children. This study evaluated associations between maltreatment, intimate partner violence, and the RET intervention with changes in children's diurnal cortisol regulation across the 1 year following the intervention, and the extent to which improvements in maternal elaborative reminiscing differed between intervention groups and mediated change in children's physiological functioning. Participants were 237 children (aged 36 to 86 months) and their mothers. Results indicated that the RET intervention was associated with significant positive change in elaborative reminiscing, which was sustained over time. Mothers’ elaboration immediately after the intervention served as a mediator of RET's effects on improvements in children's diurnal cortisol regulation (steeper diurnal slopes) from baseline to 1 year following intervention. This suggests RET is effective in facilitating physiological regulation among maltreated children.

Maternal elaborative reminiscing mediates the effect of child maltreatment on behavioral and physiological functioning / Kristin VALENTINO in Development and Psychopathology, 27-4 (Part 2) (November 2015)  

Public ISBD [article]  inDevelopment and Psychopathology > 27-4 (Part 2) (November 2015) . - p.1515-1526 Titre : Maternal elaborative reminiscing mediates the effect of child maltreatment on behavioral and physiological functioning Type de document : Texte imprimé et/ou numérique Auteurs : Kristin VALENTINO, Auteur ; Leah C. HIBEL, Auteur ; E. Mark CUMMINGS, Auteur ; Amy K. NUTTALL, Auteur ; Michelle COMAS, Auteur ; Christina G. MCDONNELL, Auteur Article en page(s) : p.1515-1526 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Theoretical and empirical evidence suggest that the way in which parents discuss everyday emotional experiences with their young children (i.e., elaborative reminiscing) has significant implications for child cognitive and socioemotional functioning, and that maltreating parents have a particularly difficult time in engaging in this type of dialogue. This dyadic interactional exchange, therefore, has the potential to be an important process variable linking child maltreatment to developmental outcomes at multiple levels of analysis. The current investigation evaluated the role of maternal elaborative reminiscing in associations between maltreatment and child cognitive, emotional, and physiological functioning. Participants included 43 maltreated and 49 nonmaltreated children (aged 3–6) and their mothers. Dyads participated in a joint reminiscing task about four past emotional events, and children participated in assessments of receptive language and emotion knowledge. Child salivary cortisol was also collected from children three times a day (waking, midday, and bedtime) on 2 consecutive days to assess daily levels and diurnal decline. Results indicated that maltreating mothers engaged in significantly less elaborative reminiscing than did nonmaltreating mothers. Maternal elaborative reminiscing mediated associations between child maltreatment and child receptive language and child emotion knowledge. In addition, there was support for an indirect pathway between child maltreatment and child cortisol diurnal decline through maternal elaborative reminiscing. Directions for future research are discussed, and potential clinical implications are addressed.

Maternal sensitivity buffers the adrenocortical implications of intimate partner violence exposure during early childhood / Leah C. HIBEL in Development and Psychopathology, 23-2 (May 2011)  

Public ISBD [article]  inDevelopment and Psychopathology > 23-2 (May 2011) . - p.689-701 Titre : Maternal sensitivity buffers the adrenocortical implications of intimate partner violence exposure during early childhood Type de document : Texte imprimé et/ou numérique Auteurs : Leah C. HIBEL, Auteur ; Douglas A. GRANGER, Auteur ; Clancy BLAIR, Auteur ; Martha J. COX, Auteur ; THE FAMILY LIFE PROJECT KEY INVESTIGATORS, Auteur Année de publication : 2011 Article en page(s) : p.689-701 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This study prospectively examined the effect of intimate partner violence (IPV) on adrenocortical reactivity and recovery during early childhood. The sample (n = 1102 mother–infant dyads; 49.2% male) was racially diverse and from predominantly low-income, rural communities. To measure IPV exposure mothers completed the Conflicts Tactics Scale, and her caretaking behaviors were observed when her child was approximately 7, 15, and 24 months of age. Children's saliva samples, later assayed for cortisol, were collected around challenge tasks designed to elicit emotional reactivity. IPV was related to a trajectory of increased cortisol reactivity from infancy to toddlerhood. By contrast, the trajectory for non-IPV-exposed children decreased in cortisol reactivity across 7 to 24 months of age. At the 24-month assessment, on average, toddlers did not exhibit a cortisol reaction; however, those exposed to high levels of violence continued to have reactivity. Accumulative levels of IPV across the first 2 years of life predicted cortisol reactivity at 24 months of age. Early (7-month) sensitive maternal behavior moderated this relationship, so that only children exposed to both early insensitivity and high accumulated IPV exhibited increased reactivity at the 24-month assessment. Findings are discussed in relation to the risky family framework.
