This longitudinal study examined the unique and joint effects of early adolescent temperament and parenting in predicting the development of adolescent internalizing symptoms in a cross-cultural sample. Participants were 544 early adolescents (T1: Mage=12.58; 49.5% female) and their mothers (n=530) from Medellin, Colombia (n=88), Naples, Italy (n=90), Rome, Italy (n=100) and Durham, North Carolina, United States (African Americans n=92, European Americans n=97, and Latinx n=77).

Aim. This study explores the association between sleep quality and emotional regulation, and investigates the genetic and environmental bases of this association.

The role of genes and environment in the relation between self-regulation and adjustment is unclear. We investigated, with the twin design, genetic and environmental components of the association between effortful control (EC) and indicators of psychological adjustment using adolescents’ and parents’ reports for 774 twins. Genetic factors explained a substantial proportion of variance in EC (58%) and the outcome variables of optimism (55%), general self-esteem (45%), happiness (48%), and self-derogation (29%). Perceived competence had no significant genetic component.
