Out of harm's way: Secure versus insecure–disorganized attachment predicts less adolescent risk taking related to childhood poverty / Brianna C. DELKER in Development and Psychopathology, 30-1 (February 2018)  

Public ISBD [article]  inDevelopment and Psychopathology > 30-1 (February 2018) . - p.283-296 Titre : Out of harm's way: Secure versus insecure–disorganized attachment predicts less adolescent risk taking related to childhood poverty Type de document : Texte imprimé et/ou numérique Auteurs : Brianna C. DELKER, Auteur ; Rosemary E. BERNSTEIN, Auteur ; Heidemarie K. LAURENT, Auteur Article en page(s) : p.283-296 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Although some risk taking in adolescence is normative, evidence suggests that adolescents raised in conditions of socioeconomic disadvantage are disproportionately burdened with risk taking and its negative consequences. Using longitudinal data from the NICHD Study of Early Child Care and Youth Development, we investigated quality of the early caregiving environment as a potential prospective buffer against the long-term association between childhood poverty and adolescent risk taking. Multicategorical moderation model results indicated that if raised in poverty across age 1–54 months (average family income to needs ratio ? 1.02), relative to affluence (income to needs ratio ? 6.16), adolescents with histories of secure attachment to caregivers exhibited two times the number of risk behaviors at age 15, whereas adolescents with insecure–disorganized histories exhibited nearly five times the number of risk behaviors. Both early family economic hardship and history of insecure–disorganized attachment remained significant predictors of increased adolescent risk taking, alongside the interactive effect. Probing the interaction's region of significance revealed that history of secure (vs. insecure–disorganized) attachment is associated with protective reductions in risk taking below a family income to needs ratio of 2.24, or about 220% poverty level. Findings support a diathesis–stress model in which children with secure attachment histories are less deleteriously impacted by early socioeconomic adversity than their insecure–disorganized peers.

Risky shifts: How the timing and course of mothers' depressive symptoms across the perinatal period shape their own and infant's stress response profiles / Heidemarie K. LAURENT in Development and Psychopathology, 23-2 (May 2011)  

Public ISBD [article]  inDevelopment and Psychopathology > 23-2 (May 2011) . - p.521-538 Titre : Risky shifts: How the timing and course of mothers' depressive symptoms across the perinatal period shape their own and infant's stress response profiles Type de document : Texte imprimé et/ou numérique Auteurs : Heidemarie K. LAURENT, Auteur ; Jennifer C. ABLOW, Auteur ; Jeffrey MEASELLE, Auteur Année de publication : 2011 Article en page(s) : p.521-538 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : We investigated the effects of timing and the course of maternal perinatal depressive symptoms on mother–infant hypothalamic–pituitary–adrenal (HPA) response profiles during an attachment stressor, as well as on within-dyad synchrony of stress profiles: coordination of HPA and sympathetic nervous system and infant–mother HPA attunement. Mothers (n = 86) completed the Center for Epidemiological Studies Depression Scale during pregnancy (Time 1 [T1]) and at 5 months (T2) and 18 months (T3) postnatal. At T3 mother–infant dyads completed the Strange Situation, and four saliva samples collected from both mothers and infants were assayed for cortisol and α-amylase. Hierarchical linear modeling was used to predict mother–infant cortisol response trajectories and within-dyad synchronies by main and interactive effects of T1–T3 Center for Epidemiological Studies Depression Scale scores. Main effects of earlier (T1, T2) depressive symptoms predicted mothers' cortisol trajectories and coordination, and interactions of T1 with postnatal (T2 and T3) symptoms predicted infants' cortisol trajectories, coordination, and attunement. Decomposition of interactions revealed more marked effects on infant cortisol trajectories when the mother shifted from higher to lower depressive symptoms (or vice versa) across the perinatal period. Shifts from lower to higher symptoms also predicted inverse coordination of cortisol with salivary α-amylase and greater attunement of infant with mother cortisol. Implications for the development and transmission of stress dysregulation are discussed.

Understanding the unfolding of stress regulation in infants / Heidemarie K. LAURENT in Development and Psychopathology, 28-4 pt2 (November 2016)  

Public ISBD [article]  inDevelopment and Psychopathology > 28-4 pt2 (November 2016) . - p.1431-1440 Titre : Understanding the unfolding of stress regulation in infants Type de document : Texte imprimé et/ou numérique Auteurs : Heidemarie K. LAURENT, Auteur ; Gordon T. HAROLD, Auteur ; Leslie LEVE, Auteur ; Katherine H. SHELTON, Auteur ; Stephanie H. M. VAN GOOZEN, Auteur Article en page(s) : p.1431-1440 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Early identification of problems with psychosocial stress regulation is important for supporting mental and physical health. However, we currently lack knowledge about when reliable individual differences in stress-responsive physiology emerge and which aspects of maternal behavior determine the unfolding of infants' stress responses. Knowledge of these processes is further limited by analytic approaches that do not account for multiple levels of within- and between-family effects. In a low-risk sample (n = 100 dyads), we observed infant cortisol and mother/infant behavior during regular play and stress sessions longitudinally from age 1 to 3, and used a three-level model to separately examine variability in infant cortisol trajectories within sessions, across years, and across infants. Stable individual differences in hypothalamus–pituitary–adrenal axis regulation were observed in the first 3 years of life. Infants of less sensitive and more intrusive mothers manifested stress sensitization, that is, elevated cortisol levels during and following stress exposure, a profile related to behavioral distress. These findings have important practical implications, suggesting that children at risk for long-term stress dysregulation may be identified in the earliest years of life.
