Validation of an adapted procedure to collect hair for cortisol determination in adolescents
Adaption of the collection protocol for hair cortisol determination
(Elsevier, 2016-08)
Introduction
In the last decades, cortisol has been extensively studied in association to early exposure to adversity as well as in the etiology of a number of physical and mental problems. While saliva and blood samples ...
The gene–environmental architecture of the development of adolescent substance use
Gene–environmental architecture of adolescent substance use
(Cambridge University Press, 2018-02-19)
Background: Using a longitudinal twin design and a latent growth curve/autoregressive
approach, this study examined the genetic-environmental architecture of substance use across
adolescence.
Methods: Self-reports of ...
Friendship experiences and anxiety among children : a genetically informed study
(Taylor & Francis, 2016)
This study examined (a) whether, in line with a gene-environment correlation (rGE), a genetic disposition for anxiety puts children at risk of having anxious friends or having no reciprocal friends; (b) to what extent these ...
Links between the mother-adolescent and father-adolescent relationships and adolescent depression : a genetically informed study
Links between the parent-adolescent Relationship quality and depression
(Taylor & Francis, 2017-08-18)
This study examined the unique roles of support and conflict in the relationship with the
mother and the father in predicting changes in adolescents’ depressive symptoms over a 1-
year period. Potential moderating effects ...
Longitudinal links between gambling participation and academic performance in youth : a test of four models
Gambling participation and academic achievement
(Springer, 2018-09-30)
Gambling participation and low academic performance are related during adolescence, but the causal mechanisms underlying this link are unclear. It is possible that gambling participation impairs academic performance. ...
Persistence and innovation effects in genetic and environmental factors in negative emotionality during infancy : a twin study
(Public Library of Science, 2017-04-27)
Background
Difficult temperament in infancy is a risk factor for forms of later internalizing and externalizing
psychopathology, including depression and anxiety. A better understanding of the roots
of difficult temperament ...
Environmental influence of problematic social relationships on adolescents' daily cortisol secretion : a monozygotic twin-difference study
(Cambridge University Press, 2017-02)
BACKGROUND:
This study investigated the potential environmental effects of peer victimization and the quality of relationships with parents and friends on diurnal cortisol secretion in mid-adolescence.
METHOD: ...
Genetic and environmental influences on height from infancy to early adulthood : an individualbased pooled analysis of 45 twin cohorts
(Nature Publishing Group, 2016-06-23)
Height variation is known to be determined by both genetic and environmental factors, but a systematic description of how their influences differ by sex, age and global regions is lacking. We conducted an individual-based ...
Serotonin transporter promoter methylation in peripheral cells and neural responses to negative stimuli : a study of adolescent monozygotic twins
(Springer Nature, 2018-08-08)
Several studies have examined associations between peripheral DNA methylation patterns of the serotonin transporter
gene (SLC6A4) promoter and symptoms of depression and anxiety. The SLC6A4 promoter methylation has also ...
Twin’s birth-order differences in height and body mass index from birth to old age: a pooled study of 26 twin cohorts participated in the CODATwins project
(Australian Academic Press, 2016-04)
We analyzed birth order differences in means and variances of height and body mass index (BMI) in monozygotic (MZ) and dizygotic (DZ) twins from infancy to old age. The data were derived from the international CODATwins ...
