It's not just what you have, but when
As the mental health of young adults is declining, finding effective strategies to support them is crucial. Young people who possess, or are exposed to, more developmental assets report higher well‐being and fewer mental problems. Developmental assets are promotive factors that include both individual strengths, like strong social skills and positive identity, and external resources, like supportive relationships and safe living conditions. Howev…
A longitudinal study of adolescent pathways differentiating suicide ideation and attempt in early adulthood
OBJECTIVE: Suicide ideation and attempt are leading risk factors for mortality in young adults. However, the adolescent risk factors distinguishing suicide ideation from attempt in young adults remain unclear. The present study aimed to examine the extent to which within-person stability and change in depressive symptoms, school difficulties, and peer victimization from ages 12 to 17 were differentially associated with later suicide ideation and …
Research Review
BACKGROUND: Mental health problems and traits capturing psychopathology are common and often begin during adolescence. Decades of twin studies indicate that genetic factors explain around 50% of individual differences in adolescent psychopathology. In recent years, significant advances, particularly in genomics, have moved this work towards more translational findings. METHODS: This review provides an overview of the past decade of genetically se…
Trajectories of childhood bullying behaviors and conduct problems
Bullying behaviors and conduct problems are two forms of antisocial behavior that frequently co-occur in childhood. However, it remains unclear whether their developmental trajectories are distinct and the extent to which different aspects of cognitive functioning account for their development. We aimed to disentangle the developmental trajectories of bullying behaviors and conduct problems, test their interrelations across childhood, and assess …
A cross‐lagged twin study of emotional symptoms, social isolation and peer victimisation from early adolescence to emerging adulthood
BACKGROUND: Emotional symptoms, such as anxiety and depressive symptoms, are common during adolescence, often persist over time, and can precede the emergence of severe anxiety and depressive disorders. Studies suggest that a vicious cycle of reciprocal influences between emotional symptoms and interpersonal difficulties may explain why some adolescents suffer from persisting emotional symptoms. However, the role of different types of interperson…
Polygenic risk score and peer victimisation independently predict depressive symptoms in adolescence
BACKGROUND: Peer victimisation has been associated with depressive symptoms during adolescence, however not all peer victimised adolescents will exhibit such symptoms. This study tested whether having a genetic predisposition to developing depression increased the risk of experiencing depressive symptoms in peer victimised youth. To date, no study has explored such gene-environment interaction using a polygenic risk score for depression (PRS-depr…
The Intensity of Formal Child-Care Attendance Decreases the Shared Environment Contribution to School Readiness
The purpose of this study was to explore if child-care intensity (hours/weeks) and age of onset could moderate genetic and environmental contributions to school readiness. A sample of 648 (85% Whites; 50% Females) pairs of twins was used to compute a GxE, CxE and ExE interaction analyses. The moderation model showed that shared environment explains 48% of individual differences in school readiness for children not attending formal child-care, and…
Polygenic scores differentially predict developmental trajectories of subtypes of social withdrawal in childhood
BACKGROUND: Children who consistently withdraw from social situations face increased risk for later socioemotional difficulties. Twin studies indicate that genetic factors substantially account for the persistence of social withdrawal over time. However, the molecular genetic etiology of chronic courses of social wariness and preference for solitude, two dimensions of social withdrawal, remains undocumented. The objectives of the present study we…
Social wariness, preference for solitude, and peer difficulties in middle childhood
The present study examined, within a longitudinal family-informed design and across middle childhood, the predictive associations between preference for solitude and social wariness, two forms of social withdrawal, and peer difficulties. Specifically, preference for solitude, rather than social wariness, was expected to predict peer victimization and rejection, two aspects of peer difficulties. A total of 1,014 children from the Quebec Newborn Tw…
