Data are from 854 male and female, same-sex adult twin pairs born between 1926 and 1971 (32 “60 years old, M = 44.9 years, SD = 4.9 years) from the Twin and Offspring Study in Sweden and their adolescent offspring (11 “22 years old, M = 15.7 years, SD = 2.4 years, 52% female). Children-of-twins models revealed additive (9%) and dominant (45%) genetic and nonshared environmental (47%) influences on twins’ symptom severity, and additive genetic (39%) and nonshared environmental (61%) influences on twins’ symptom directionality. Both comorbid problems and preponderance of symptoms of a particular “ internalizing versus externalizing “ spectrum were correlated across parent and child generations, although associations were modest especially for directionality (i.e., transmission of specific symptom type). By interpreting findings alongside a recent study of adolescent twins, we demonstrate that the intergenerational transmission of symptom severity and symptom directionality are both unlikely to be attributable to genetic transmission, are both likely to be influenced by direct phenotypic transmission and/or nonpassive rGE, and the intergenerational transmission of symptom severity is also likely to be influenced by passive rGE.

The roles of familial transmission and smoking during pregnancy on executive function skills: A sibling-comparison study / Valerie S. KNOPIK in Development and Psychopathology, 34-5 (December 2022)  

Public ISBD [article]  inDevelopment and Psychopathology > 34-5 (December 2022) . - p.1803-1815 Titre : The roles of familial transmission and smoking during pregnancy on executive function skills: A sibling-comparison study Type de document : Texte imprimé et/ou numérique Auteurs : Valerie S. KNOPIK, Auteur ; Lauren MICALIZZI, Auteur ; Kristine MARCEAU, Auteur ; Amy M. LOVISKA, Auteur ; Li YU, Auteur ; Alexandra BIEN, Auteur ; Emily ROLAN, Auteur ; Allison S. EVANS, Auteur ; Rohan H. C. PALMER, Auteur ; Andrew C. HEATH, Auteur Article en page(s) : p.1803-1815 Langues : Anglais (eng) Mots-clés : executive function  family studies  smoking during pregnancy Index. décimale : PER Périodiques Résumé : This research examines maternal smoking during pregnancy and risk for poorer executive function in siblings discordant for exposure. Data (N = 173 families) were drawn from the Missouri Mothers and Their Children study, a sample, identified using birth records (years 1998 “2005), in which mothers changed smoking behavior between two pregnancies (Child 1 [older sibling]: Mage = 12.99; Child 2 [younger sibling]: Mage = 10.19). A sibling comparison approach was used, providing a robust test for the association between maternal smoking during pregnancy and different aspects of executive function in early-mid adolescence. Results suggested within-family (i.e., potentially causal) associations between maternal smoking during pregnancy and one working memory task (visual working memory) and one response inhibition task (color-word interference), with increased exposure associated with decreased performance. Maternal smoking during pregnancy was not associated with stop-signal reaction time, cognitive flexibility/set-shifting, or auditory working memory. Initial within-family associations between maternal smoking during pregnancy and visual working memory as well as color-word interference were fully attenuated in a model including child and familial covariates. These findings indicate that exposure to maternal smoking during pregnancy may be associated with poorer performance on some, but not all skills assessed; however, familial transmission of risk for low executive function appears more important.
