Abstract
Background
Certain temperament characteristics, such as low effortful control and high negative affectivity, are linked to an elevated likelihood for later psychopathology. Although genetic vulnerability has been associated with a number of psychiatric conditions, little work has examined the genetic architecture underlying temperament or the genetic overlap between early temperament profiles and later mental health outcomes. The present study examined associations of polygenic scores for anxiety (PGS-Anxiety) and ADHD (PGS-ADHD) with temperament characteristics in a longitudinal sample of children assessed from infancy through age 7 years.
Methods
Analyses were conducted in a sample of children (European Ancestry n = 476; Full Sample [European and other ancestries] N = 606).
Results
We observed an age-by-PGS interaction on effortful control. As children aged, there appeared to be stronger negative associations between PGS-ADHD and effortful control. No associations were observed between PGS-Anxiety and negative affectivity.
Conclusions
Overall, the findings suggest some support for associations between genetic underpinnings for externalizing psychopathology and temperament that increase over time.
期刊介绍：
The Journal of Child Psychology and Psychiatry (JCPP) is a highly regarded international publication that focuses on the fields of child and adolescent psychology and psychiatry. It is recognized for publishing top-tier, clinically relevant research across various disciplines related to these areas. JCPP has a broad global readership and covers a diverse range of topics, including:
Epidemiology: Studies on the prevalence and distribution of mental health issues in children and adolescents.
Diagnosis: Research on the identification and classification of childhood disorders.
Treatments: Psychotherapeutic and psychopharmacological interventions for child and adolescent mental health.
Behavior and Cognition: Studies on the behavioral and cognitive aspects of childhood disorders.
Neuroscience and Neurobiology: Research on the neural and biological underpinnings of child mental health.
Genetics: Genetic factors contributing to the development of childhood disorders.
JCPP serves as a platform for integrating empirical research, clinical studies, and high-quality reviews from diverse perspectives, theoretical viewpoints, and disciplines. This interdisciplinary approach is a key feature of the journal, as it fosters a comprehensive understanding of child and adolescent mental health.
The Journal of Child Psychology and Psychiatry is published 12 times a year and is affiliated with the Association for Child and Adolescent Mental Health (ACAMH), which supports the journal's mission to advance knowledge and practice in the field of child and adolescent mental health.
