Early adolescents' temperament, emotion regulation during mother–child interactions, and depressive symptomatology / Marie B.H. YAP in Development and Psychopathology, 23-1 (January 2011)

SHEEBER, Auteur Année de publication : 2011 Article en page(s) : p.267-282 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This study examined the relations among temperament, emotion regulation, and depressive symptoms in early adolescents. Early adolescents provided self-reports of temperament on two occasions, as well as reports on emotion regulation and depressive symptomatology. Furthermore, 163 of these adolescents participated in event-planning and problem-solving interactions with their mothers. Adolescents with temperaments that were high in negative emotionality or low in effortful control displayed more emotionally dysregulated behaviors during the interaction tasks, reported having maladaptive responses to negative affect more often and adaptive responses less often, and had more depressive symptoms. In particular, adolescents with the high negative emotionality and low effortful control temperament combination reported the highest levels of depressive symptomatology. Sequential analyses of family interactions indicated that adolescents with more depressive symptoms were more likely to reciprocate their mothers' negative affective behaviors. Adolescents' adaptive and maladaptive responses to negative affect mediated the associations between their temperament and concurrent depressive symptoms.

Hippocampal volume and sensitivity to maternal aggressive behavior: A prospective study of adolescent depressive symptoms / Sarah WHITTLE in Development and Psychopathology, 23-1 (January 2011)  

Public ISBD [article]  inDevelopment and Psychopathology > 23-1 (January 2011) . - p.115-129 Titre : Hippocampal volume and sensitivity to maternal aggressive behavior: A prospective study of adolescent depressive symptoms Type de document : Texte imprimé et/ou numérique Auteurs : Sarah WHITTLE, Auteur ; Marie B.H.

ALLEN, Auteur Année de publication : 2011 Article en page(s) : p.115-129 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : It has been suggested that biological factors confer increased sensitivity to environmental influences on depressive symptoms during adolescence, a crucial time for the onset of depressive disorders. Given the critical role of the hippocampus in sensitivity to stress and processing of contextual aspects of the environment, investigation of its role in determining sensitivity to environmental context seems warranted. This study prospectively examined hippocampal volume as a measure of sensitivity to the influence of aggressive maternal behavior on change in depressive symptoms from early to midadolescence. The interaction between aggressive maternal behavior and hippocampal volume was found to predict change in depressive symptoms. Significant sex differences also emerged, whereby only for girls were larger bilateral hippocampal volumes more sensitive to the effects of maternal aggressive behavior, particularly with respect to experiencing the protective effects of low levels of maternal aggressiveness. These findings help elucidate the complex relationships between brain structure, environmental factors such as maternal parenting style, and sensitivity to (i.e., risk for, and protection from) the emergence of depression during this life stage. Given that family context risk factors are modifiable, our findings suggest the potential utility of targeted parenting interventions for the prevention and treatment of adolescent depressive disorder.

Pituitary volume prospectively predicts internalizing symptoms in adolescence / Amy R. ZIPURSKY in Journal of Child Psychology and Psychiatry, 52-3 (March 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-3 (March 2011) . - p.315-323 Titre : Pituitary volume prospectively predicts internalizing symptoms in adolescence Type de document : Texte imprimé et/ou numérique Auteurs : Amy R. ZIPURSKY, Auteur ; Sarah WHITTLE, Auteur ; Murat YUCEL, Auteur ; Valentina LORENZETTI, Auteur ; Stephen J. WOOD, Auteur ; Dan I. LUBMAN, Auteur ; Julian G. SIMMONS, Auteur ; Nicholas B. ALLEN, Auteur Année de publication : 2011 Article en page(s) : p.315-323 Langues : Anglais (eng) Mots-clés : Pituitary volume  depression  anxiety  externalizing  adolescence  HPA axis Index. décimale : PER Périodiques Résumé : Background:  Early adolescence is a critical time for the development of both internalizing and externalizing disorders. We aimed to investigate whether pituitary volume, an index of hypothalamic–pituitary–adrenal (HPA) axis function, represents a vulnerability factor for the emergence of internalizing and externalizing symptoms during adolescence using a prospective, longitudinal design. Methods:  One hundred and fifty-five adolescents completed 3T structural magnetic resonance imaging (MRI), symptom rating scales and a diagnostic interview during early adolescence (M age 12.6 years, SD .5 years); symptom rating scales were re-administered approximately three years later (M age 15.2 years). The volume of the pituitary gland was estimated by manually delineating its structure on MR images. The degree to which pituitary volumes prospectively predicted change in internalizing and externalizing symptoms across the two time-points was assessed using hierarchal linear regression, after controlling for the influence of gender, age, pubertal stage and intracranial volume. Results:  Larger pituitary volumes prospectively predicted an increase in internalizing, but not externalizing, symptoms from early adolescence to mid-adolescence. Conclusions:  This study provides the first evidence that increased pituitary volume might represent a specific vulnerability marker for the development of internalizing symptoms during early to mid-adolescence.
