Background: Victimisation has been associated with self-harm (with or without suicidal intent), but little is known about this association during young adulthood-a distinct developmental period. Further, not all individuals who experience victimisation will later engage in self-harm, suggesting ...

Background: We recently reported evidence that a biopsychosocial model predicts lifetime histories of commonly comorbid early-onset psychiatric disorders. This transdiagnostic model was produced when incorporating either positron emission tomography-measured midbrain dopamine autoreceptors or f ...

Objective: Several studies have shown that maladaptive eating behaviors in childhood predict greater risk for eating disorders in adolescence. Whether or not maladaptive eating behaviors could represent developmental risk factors for a larger spectrum of psychopathologies is unknown. This study described longitudinal trajectories of overeating and picky ...

The lack of polygenic scores (PGSs) developed for body-mass index (BMI) in children may be problematic because the genetic architecture characterizing BMI changes throughout life. This study aims to describe the genetic susceptibility to obesity in children and to compare two PGSs based on data from adults and children and their association with BMI and ...

Individual differences in physical aggression (PA) are largely heritable. However, it remains unclear how genetic propensity for aggression manifests early in life and relates to school-age PA. Preschool externalizing behavior problems (EXT) and adverse experiences are known predictors of schoo ...

Background: Adolescent alcohol use is the norm, but only some develop a substance use disorder. The increased risk might reflect heightened mesocorticolimbic responses to reward-related cues but results published to date have been inconsistent. Methods: Young social drinkers (age 18.5 ± 0.6 y. ...

Childhood maltreatment is linked with later depressive symptoms, but not every maltreated child will experience symptoms later in life. Therefore, we investigate whether genetic predisposition for depression (i.e., polygenic score for depression, PGSDEP) modifies the association between maltrea ...

Background: Cross-sectional studies have shown that hyperactivity and impaired executive functioning are associated with symptoms of eating disorders in adolescence and adulthood. Whether hyperactivity and executive functions in early life can prospectively predict the emergence of eating disorder symptoms in adolescence remains unknown. The present stu ...

Eating disorders have early origins, and there could be a continuum between childhood eating behaviors, such as overeating, and long-term disordered eating, but this remains to be shown. BMI, desire for thinness and peer victimization could influence this continuum, but their interactions are unknown. To fill this gap, the study used data from the Quebe ...

Both common pain and anxiety problems are widespread, debilitating and often begin in childhood-adolescence. Twin studies indicate that this co-occurrence is likely due to shared elements of risk, rather than reciprocal causation. A joint genome-wide investigation and pathway/network-based anal ...
