Genetic and environmental influences on temperament development across the preschool period / Chang LIU in Journal of Child Psychology and Psychiatry, 64-1 (January 2023)
[article]
Titre : Genetic and environmental influences on temperament development across the preschool period Type de document : Texte imprimé et/ou numérique Auteurs : Chang LIU, Auteur ; Yao ZHENG, Auteur ; Jody M. GANIBAN, Auteur ; Kimberly J. SAUDINO, Auteur Article en page(s) : p.59-70 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background Preschoolers' temperament characteristics are associated with children's long-term development. Such links underscore the importance of understanding factors that shape temperament during preschool. This is the first study to examine genetic and environmental sources of developmental growth in three temperament dimensions: surgency, negative affectivity, and effortful control, during the preschool period. Methods Biometric latent growth curve modeling was used to examine genetic, shared, and nonshared environmental contributions to the invariant level of and developmental growth in temperament, using a sample of 310 same-sex twin pairs (MZ=123, DZ=187) assessed at 3, 4, and 5 years of age. Temperament was assessed using primary caregiver's report on the Child Behavior Questionnaire-Short Form. Results All three temperament dimensions demonstrated linear increases from ages 3 to 5 years. The invariant levels of all three temperament dimensions were explained by genetic and nonshared environmental factors. Growth in surgency was fully explained by nonshared environmental factors, while growth in negative affectivity was mainly explained by genetic factors. Growth in effortful control was explained by genetic and nonshared environmental factors, although neither were significant due to large bootstrap standard errors. For negative affectivity and effortful control, the genetic factors that contributed to developmental growth were independent from those associated with their invariant levels. Conclusions Collectively, these findings indicate that both genetic and nonshared environmental factors play important roles in the invariant levels of temperament. Findings also accord a critical role of children's nonshared environment in the development of surgency and to a lesser extent negative affectivity and effortful control. It is also notable that novel genetic effects contribute to developmental growth in negative affectivity and effortful control as children age, emphasizing the importance of integrating developmental models in genetic research.

Titre : A long-term look at ?early starters?: Predicting adult psychosocial outcomes from childhood conduct problem trajectories Type de document : Texte imprimé et/ou numérique Auteurs : Maeve CYR, Auteur ; Yao ZHENG, Auteur ; Robert J. MCMAHON, Auteur Article en page(s) : p.225-240 Langues : Anglais (eng) Mots-clés : adult outcomes conduct problems early starters latent class growth analysis trajectories Index. décimale : PER Périodiques Résumé : Current evidence suggests that multiple pathways of ?early-starting? conduct problems exist, including persisting and declining trajectories. Since relatively little is known about the early onset-declining pathway, this study examined the long-term outcomes of different childhood conduct problem trajectories in a disproportionately high-risk sample (N = 754). Parents reported on children's conduct problems at six time points (kindergarten to grade 7). At age 25, psychosocial outcomes were assessed across five domains (psychopathology, substance use, risky sexual behavior, antisocial behavior, and adaptive outcomes). Four childhood conduct problem trajectories were identified: extremely high increasing (EHI; 3.7%), high stable (HS; 22.0%), moderate decreasing (MD; 38.8%), and low decreasing (LD; 35.5%). The EHI and HS groups displayed the poorest psychosocial functioning at age 25, whereas the LD group exhibited the most positive adjustment. Although individuals in the MD group displayed relatively positive adjustment on some outcomes, they displayed more psychopathology and lower well-being in adulthood than the LD group. These findings suggest that there are diverse pathways of early-starting conduct problems, and that all early starters are at risk for later maladjustment. However, the degree and type of risk is related to the severity of conduct problems throughout childhood.
