A longitudinal twin study of callous-unemotional traits during childhood
Longitudinal twin callous-unemotional, 1
(American Psychological Association, 2018-05)
Previous research indicates that genetic factors largely account for the stability of callous-unemotional (CU) traits in adolescence. However, the genetic-environmental etiology of the development of CU traits has not been ...
Does shyness interact with peer group affiliation in predicting substance use in adolescence?
(American Psychological Association, 2017-11-20)
Cigarette use and binge drinking are risky behaviors emerging during adolescence. Although many beneficial factors are well documented, studies linking shyness to substance use are somehow conflicting, which may be due to ...
A longitudinal empirical investigation of the pathways model of problem gambling
Longitudinal investigation of the pathways model
(Springer, 2017-12-31)
Background and Aims: The Pathways Model of Problem Gambling suggests the existence of
three developmental pathways to problem gambling, each differentiated by a set of predisposing
biopsychosocial characteristics: ...
Early warm-rewarding parenting moderates the genetic contributions to callous-unemotional traits in childhood
Warm-rewarding genetic callous-unemotional
(Wiley, 2018-04-23)
Background
Previous gene–environment interaction studies of CU traits have relied on the candidate gene approach, which does not account for the entire genetic load of complex phenotypes. Moreover, these studies have not ...
A prospective, longitudinal, study of men with borderline personality disorder with and without comorbid antisocial personality disorder
(BMC, 2017-12)
Background: Some evidence suggests that the prevalence of Borderline Personality Disorder (BPD) is elevated among
male criminal offenders. It is not presently known whether offending, and violent offending, are limited to ...
The expression of genetic risk for aggressive and non-aggressive antisocial behavior is moderated by peer group
(Springer, 2015-07)
Numerous studies have shown that aggressive and non-aggressive antisocial behaviors are important precursors of later adjustment problems. There is also strong empirical evidence that both types of antisocial behavior are ...
The genetic and environmental etiology of the association between vocabulary and syntax in first grade
Etiology of vocabulary and syntax
(Taylor & Francis, 2018-03-09)
This study examined the genetic and environmental etiology of vocabulary, syntax, and their association in first graders. French-speaking same-sex twins (N = 555) completed two vocabulary tests, and two scores of syntax ...
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 ...
Identifying at-risk profiles and protective factors for problem gambling : a longitudinal study across adolescence and early adulthood
(American Psychological Association, 2018-03-19)
Past studies have identified various risk and protective factors for problem gambling (PG). However, no study has examined the interplay between these factors using a combination of person-centered and variable-centered ...
Persistent genetic and family-wide environmental contributions to early number knowledge and later achievement in mathematics
Etiology of early math knowledge and skills development
(SAGE, 2017-10-03)
This study investigated the stable and transient genetic and environmental contributions to
individual differences in number knowledge in the transition from preschool (age 5) to Grade 1
(age 7) and to the predictive ...
