Bidirectional genetic and environmental influences on mother and child behavior: The family system as the unit of analyses / W. Roger MILLS-KOONCE in Development and Psychopathology, 19-4 (Fall 2007)  

Public ISBD [article]  inDevelopment and Psychopathology > 19-4 (Fall 2007) . - p.1073-1087 Titre : Bidirectional genetic and environmental influences on mother and child behavior: The family system as the unit of analyses Type de document : Texte imprimé et/ou numérique Auteurs : W. Roger MILLS-KOONCE, Auteur ; Martha J. COX, Auteur ; Cathi B. PROPPER, Auteur ; Jean-Louis GARIEPY, Auteur ; Clancy BLAIR, Auteur ; Patricia GARRETT-PETERS, Auteur Année de publication : 2007 Article en page(s) : p.1073-1087 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Family systems theory proposes that an individual's functioning depends on interactive processes within the self and within the context of dyadic family subsystems. Previous research on these processes has focused largely on behavioral, cognitive, and psychophysiological properties of the individual and the dyad. The goals of this study were to explore genetic and environmental interactions within the family system by examining how the dopamine receptor D2 gene (DRD2) A1+ polymorphism in mothers and children relates to maternal sensitivity, how maternal and child characteristics might mediate those effects, and whether maternal sensitivity moderates the association between DRD2 A1+ and child affective problems. Evidence is found for an evocative effect of child polymorphism on parenting behavior, and for a moderating effect of child polymorphism on the association between maternal sensitivity and later child affective problems. Findings are discussed from a family systems perspective, highlighting the role of the family as a context for gene expression in both mothers and children.

Interparental aggression, attention skills, and early childhood behavior problems / Nissa R. TOWE-GOODMAN in Development and Psychopathology, 23-2 (May 2011)

COX, Auteur ; THE FAMILY LIFE PROJECT KEY INVESTIGATORS, Auteur Année de publication : 2011 Article en page(s) : p.563-576 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The current study explored longitudinal associations between interparental aggression, the development of child attention skills, and early childhood behavior problems in a diverse sample of 636 families living in predominately low-income, nonmetropolitan communities. The results of latent-variable, cross-lagged longitudinal models revealed that maternal-reported interparental aggression in infancy predicted reduced observed attention skills in toddlerhood; no association was observed, however, between attention in infancy and interparental aggression during the toddler years. Further, reduced toddler attention and high interparental aggression were both associated with increased risk for attention-deficit/hyperactivity disorder symptoms and conduct problems at 3 years of age. Processes largely operated in similar ways regardless of child gender or low-income status, although a few differences were observed. Overall, the results suggest that interparental aggression undermines attention development, putting children's early behavioral adjustment at risk.

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.

Systems theory and cascades in developmental psychopathology / Martha J. COX in Development and Psychopathology, 22-3 (August 2010)

PROPPER, Auteur ; Jean-Louis GARIEPY, Auteur Année de publication : 2010 Article en page(s) : p.497-506 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : In the wake of prominent theoreticians in developmental science, whose contributions we review in this article, many developmental psychologists came to endorse a systems approach to understanding how the individual, as it develops, establishes functional relationships to social ecological contexts that from birth to school entry rapidly increase in complexity. The concept of developmental cascade has been introduced in this context to describe lawful processes by which antecedent conditions may be related with varying probabilities to specified outcomes. These are understood as processes by which function at one level or in one domain of behavior affect the organization of competency in later developing domains of general adaptation. Here we propose a developmental sequence by which the developing child acquires regulative capacities that are key to adjustment to a society that demands considerable control of emotional and cognitive functions early in life. We report empirical evidence showing that the acquisition of regulative capacities may be understood as a cascade of shifts in control parameters induced by the progressive integration of biological, transactional, and socioaffective systems over development. We conclude by suggesting how the developmental process may be accessed for effective intervention in populations deemed “at risk” for later problems of psychosocial adjustment.

Trajectories of internalizing problems across childhood: Heterogeneity, external validity, and gender differences / Sonya K. STERBA in Development and Psychopathology, 19-2 (Spring 2007)  

Public ISBD [article]  inDevelopment and Psychopathology > 19-2 (Spring 2007) . - p.345-366 Titre : Trajectories of internalizing problems across childhood: Heterogeneity, external validity, and gender differences Type de document : Texte imprimé et/ou numérique Auteurs : Sonya K. STERBA, Auteur ; Mitchell J. PRINSTEIN, Auteur ; Martha J. COX, Auteur Année de publication : 2007 Article en page(s) : p.345-366 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Developmental psychopathology theory speaks to the existence of early-manifesting internalizing problems with a heterogeneous longitudinal course. However, the course of internalizing problems has been investigated largely from late childhood onward, with methods that assume children's problem trajectories vary more so in rate than in qualitative functional form. This can obscure heterogeneity in symptom process and course, obscure onset of early gender differences in internalizing problems, and obscure the relevance of early sociocontextual risks for long-term internalizing outcomes. The present study addressed these issues by using person-oriented (latent growth mixture) methods to model heterogeneity in maternal-reported internalizing symptoms from age 2 to 11 years (N = 1,364). Three latent trajectory classes were supported for each gender: two-thirds of children followed a low-stable trajectory; smaller proportions followed decreasing/increasing or elevated-stable trajectories. Although the number, shape, and predictive validity of internalizing trajectory classes were similar across gender, trajectory classes' initial values and rates of change varied significantly across gender, as did the impact of maternal postpartum depression and anxiety on latent growth factors. Extracted latent trajectories were differentially predicted by postpartum maternal psychopathology, and themselves, in several respects, differentially predicted self-reported depressive symptoms in preadolescence. However, discussion focuses on the need for further external validation of extracted latent classes.
