We followed the oldest longitudinal cohort of ELBW survivors to adulthood. Participants provided buccal cells and reported on internalizing problems, using the Young Adult Self-Report when they were in their mid-20s (ELBW/SGA, N = 28; ELBW/AGA, N = 60; NBW, N = 81) and mid-30s (ELBW/SGA, N = 27; ELBW/AGA, N = 58; NBW, N = 76). The findings indicate that ELBW/SGAs carrying the 5-HTTLPR short allele reported increased internalizing problems, particularly depression, during the third and fourth decades of life. This is the first known report on gene–environment interactions predicting psychopathology among ELBW survivors. Our findings elucidate putative neurobiological pathways that underlie risk for psychopathology.

Small for gestational age and poor fluid intelligence in childhood predict externalizing behaviors among young adults born at extremely low birth weight / Ayelet LAHAT in Development and Psychopathology, 27-1 (February 2015)

SCHMIDT, Auteur Article en page(s) : p.181-188 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Although infants born at extremely low birth weight (ELBW; birth weight < 1000 g) are at increased risk for developing later psychopathology, the mechanisms contributing to this association are largely unknown. In the present study, we examined a putative cognitive link to psychopathology in a cohort of ELBW survivors. These individuals were followed up prospectively at age 8 and again at ages 22–26. At 8 years, participants completed measures of fluid and general intelligence. As young adults, a subset of ELBW survivors free of major neurosensory impairments provided self-reports of personality characteristics related to psychopathology. Data from 66 participants indicated that, as predicted, the association between ELBW and externalizing behaviors was moderated by fluid intelligence. Specifically, ELBW individuals with poor fluid intelligence who were born small for gestational age (birth weight < 10th percentile for gestational age) showed the highest level of externalizing behaviors. These findings provide support for a cumulative risk model and suggest that fluid intelligence might be a cognitive mechanism contributing to the development of psychopathology among nonimpaired individuals who were born at ELBW and small for gestational age.

Temperamental exuberance and executive function predict propensity for risk taking in childhood / Ayelet LAHAT in Development and Psychopathology, 24-3 (August 2012)  

Public ISBD [article]  inDevelopment and Psychopathology > 24-3 (August 2012) . - p.847-56 Titre : Temperamental exuberance and executive function predict propensity for risk taking in childhood Type de document : Texte imprimé et/ou numérique Auteurs : Ayelet LAHAT, Auteur ; Kathryn A. DEGNAN, Auteur ; Lauren K. WHITE, Auteur ; Jennifer Martin MCDERMOTT, Auteur ; Heather A. HENDERSON, Auteur ; Carl W. LEJUEZ, Auteur ; Nathan A. FOX, Auteur Année de publication : 2012 Article en page(s) : p.847-56 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The present study utilized a multilevel approach to examine developmental trajectories in risk-taking propensity. We examined the moderating role of specific executive function components, attention shifting and inhibitory control, on the link between exuberant temperament in infancy and propensity for risk taking in childhood. Risk taking was assessed using a task previously associated with sensation seeking and antisocial behaviors. Two hundred ninety-one infants were brought into the lab and behaviors reflecting exuberance were observed at 4, 9, 24, and 36 months of age. Executive function was assessed at 48 months of age. Risk-taking propensity was measured when children were 60 months of age. The results indicated that exuberance and attention shifting, but not inhibitory control, significantly interacted to predict propensity for risk taking. Exuberance was positively associated with risk-taking propensity among children who were relatively low in attention shifting but unrelated for children high in attention shifting. These findings illustrated the multifinality of developmental outcomes for temperamentally exuberant young children and pointed to the distinct regulatory influences of different executive functions for children of differing temperaments. Attention shifting likely affords a child the ability to consider both positive and negative consequences and moderates the relation between early exuberance and risk-taking propensity.
