Atypical patterns of respiratory sinus arrhythmia index an endophenotype for depression / Ilya YAROSLAVSKY in Development and Psychopathology, 26-4 (Part 2) (November 2014)  

Public ISBD [article]  inDevelopment and Psychopathology > 26-4 (Part 2) (November 2014) . - p.1337-1352 Titre : Atypical patterns of respiratory sinus arrhythmia index an endophenotype for depression Type de document : Texte imprimé et/ou numérique Auteurs : Ilya YAROSLAVSKY, Auteur ; Jonathan ROTTENBERG, Auteur ; Maria KOVACS, Auteur Année de publication : 2014 Article en page(s) : p.1337-1352 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Can atypical patterns of parasympathetic nervous system activity serve as endophenotypes for depression? Using respiratory sinus arrhythmia (RSA) as an index of parasympathetic nervous system function, we examined this question in two studies: one involving mothers with and without depression histories and their offspring (at high and low risk for depression, respectively), and a further study of adolescent sibling pairs concordant and discordant for major depression. In both studies, subjects were exposed to sad mood induction; subjects' RSA was monitored during rest periods and in response to the mood induction. We used Gottesman and Gould's (2003) criteria for an endophenotype and a priori defined “atypical” and “normative” RSA patterns (combinations of resting RSA and RSA reactivity). We found that atypical RSA patterns (a) predicted current depressive episodes and remission status among women with histories of juvenile onset depression and healthy controls, (b) predicted longitudinal trajectories of depressive symptoms among high- and low-risk young offspring, (c) were concordant across mothers and their juvenile offspring, (d) were more prevalent among never-depressed youth at high risk for depression than their low-risk peers, and (e) were more concordant across adolescent sibling pairs in which both versus only one had a history of major depression. Thus, the results support atypical RSA patterns as an endophenotype for depression. Possible mechanisms by which RSA patterns increase depression risk and their genetic contributors are discussed.

Developmental trajectories of positive and negative affect in children at high and low familial risk for depressive disorder / Thomas M. OLINO in Journal of Child Psychology and Psychiatry, 52-7 (July 2011)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 52-7 (July 2011) . - p.792-799 Titre : Developmental trajectories of positive and negative affect in children at high and low familial risk for depressive disorder Type de document : Texte imprimé et/ou numérique Auteurs : Thomas M.

Methods:  We examined 202 offspring of mothers who had a history of juvenile-onset unipolar depressive disorder (n = 60) or no history of major psychopathology (n = 80). Offspring participated in up to seven annual, structured laboratory tasks that were designed to elicit PA and NA. Results:  Growth curve analyses revealed that PA increased linearly and similarly for all children from late infancy through age 9. However, there also were individual differences in early PA. Relative to control peers, offspring of mothers with lifetime unipolar depression had consistently lower levels of PA, and this association remained significant even when controlling for current maternal depression and maternal affect displays. Growth curve analyses also revealed a significant linear decrease in NA in children across time; however, there was no significant inter-individual variation either in early NA or rate of change in NA. Conclusion:  Attenuated PA (rather than excessive NA) may be an early vulnerability factor for eventual unipolar depressive disorder in at-risk children and may represent one pathway through which depression is transmitted.

Emotion regulation in preschoolers: the roles of behavioral inhibition, maternal affective behavior, and maternal depression / Xin FENG in Journal of Child Psychology and Psychiatry, 49-2 (February 2008)

Methods: Participants were 62 children and their mothers, 37 of whom had mothers with COD. Children's ER was assessed using a disappointment paradigm; temperament assessment also was laboratory-based. Results: Maternal COD was inversely related to offspring's active ER and positive mood. Among children of COD mothers, behavioral inhibition was associated with passive regulation and sadness, and maternal positivity toward these children was associated with child active ER and positive mood. Conclusion: Behavioral inhibition may place children of COD mothers at risk for developing maladaptive ways of regulating negative emotion, whereas mothers’ positivity may serve as a protective factor for them.

Methods: Participants were 49 COD offspring (ages 4–7) and 37 NCOD offspring (ages 4–7) and their mothers. Emotion regulation strategies were assessed observationally during a laboratory mood induction paradigm. Results: COD offspring were more likely to focus on the delay object or task than NCOD offspring. Daughters of COD mothers were also more likely to wait passively and less likely to engage in active distraction than daughters of NCOD mothers. These findings were replicated using number of maternal depressive episodes. Conclusions: COD offspring, especially daughters, exhibit a more passive style of regulating emotion that may place them at risk for developing psychopathology.

Facial emotion expression recognition by children at familial risk for depression: high-risk boys are oversensitive to sadness / Nestor L. LOPEZ-DURAN in Journal of Child Psychology and Psychiatry, 54-5 (May 2013)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 54-5 (May 2013) . - p.565-574 Titre : Facial emotion expression recognition by children at familial risk for depression: high-risk boys are oversensitive to sadness Type de document : Texte imprimé et/ou numérique Auteurs : Nestor L. LOPEZ-DURAN, Auteur ; Kate R. KUHLMAN, Auteur ; Charles J. GEORGE, Auteur ; Maria KOVACS, Auteur Article en page(s) : p.565-574 Langues : Anglais (eng) Mots-clés : Facial expressions  children  depression  information processing  children of depressed parents Index. décimale : PER Périodiques Résumé : Background: Offspring of depressed parents are at greatly increased risk for mood disorders. Among potential mechanisms of risk, recent studies have focused on information processing anomalies, such as attention and memory biases, in the offspring of depressed parents. In this study we examined another information processing domain, perceptual sensitivity to emotion cues in facial expressions, as a potential mechanism of risk that characterizes the offspring of depressed parents. Methods: The study included 64 children at familial-risk for depression and 40 low-risk peers between the ages 7 and 13(Mage = 9.51; SD = 2.27). Participants were presented with pictures of facial expressions that varied in emotional intensity from neutral to full-intensity sadness or anger (i.e., emotion recognition), or pictures of faces morphing from anger to sadness (emotion discrimination). After each picture was presented, children indicated whether the face showed a specific emotion (i.e., sadness, anger) or no emotion at all (neutral) using a forced choice paradigm. We examined group differences in the intensity of emotion that suggested greater sensitivity to specific emotions. Results: In the emotion recognition task, boys (but not girls) at familial-risk for depression identified sadness at significantly lower levels of emotional intensity than did their low-risk peers. The high and low-risk groups did not differ with regard to identification of anger. In the emotion discrimination task, both groups displayed over-identification of sadness in ambiguous mixed faces but high-risk youth were less likely to show this labeling bias than their peers. Conclusion: Our findings are consistent with the hypothesis that enhanced perceptual sensitivity to subtle traces of sadness in facial expressions may be a potential mechanism of risk among boys at familial-risk for depression. This enhanced perceptual sensitivity does not appear to be due to biases in the labeling of ambiguous faces.
