Genetic and environmental links between self-reports and parent-reports of child personality [PDF]

open access: yes, 2018
Personality ratings have been consistently found to be reliable and moderately heritable, but interrater agreement between self- and other-report of personality are low-to-moderate, particularly in childhood samples. The current study aims to examine the

Unravelling Twin Births in German Holstein Cows: Phenotypic Associations, Genetic Analysis and Potential Underlying Genes and Hormones

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Twin births in dairy cattle are rare but present significant challenges for animal welfare, as both the health of the cow and the calves are affected. This causes economic losses, which prompts breeders to select against twin births and identify associated risk factors.

Subclinical hypomania, psychiatric and neurodevelopmental diagnoses: phenotypic and aetiological overlap

open access: yesJournal of Child Psychology and Psychiatry, EarlyView.
Background Subclinical hypomanic symptoms are fairly common in the general population but are linked to psychiatric and neurodevelopmental conditions. However, the genetic and environmental origins of these associations are unclear. This twin study examined the phenotypic and aetiological associations between subclinical hypomania and psychiatric and ...

A person‐centered and genetically informed approach toward characterizing multidomain resilience to neighborhood disadvantage in youth

open access: yesJournal of Child Psychology and Psychiatry, EarlyView.
Background Examining resilience to adversity across multiple behavioral domains (e.g., psychological well‐being, social functioning) can better characterize positive development and inform novel prevention and intervention efforts. However, few studies have employed person‐centered methods to examine individual profiles of resilience across multiple ...

Prenatal growth markers in schizophrenia: a monozygotic co-twin control study. [PDF]

open access: yes, 1996
OBJECTIVE: This co-twin study investigated monozygotic twins who were discordant for schizophrenia for evidence of prenatal growth differences between the affected and well co-twins. METHOD: Four dermatoglyphic markers of prenatal growth were obtained by

Neurodevelopmental conditions and adaptive functioning – a co‐twin control study

open access: yesJournal of Child Psychology and Psychiatry, EarlyView.
Background Challenges in adaptive or daily functioning are inherent to diagnostic criteria for neurodevelopmental conditions (NDCs). However, less is known regarding the influence of factors that may confound the association between NDCs and adaptive functioning.

The nature and nurture of primary and secondary callous–unemotional traits: evidence from two independent twin samples

open access: yesJournal of Child Psychology and Psychiatry, EarlyView.
Background Callous–unemotional (CU) traits identify youth with more severe and chronic trajectories of conduct problems. However, the etiology of CU traits may be heterogeneous, undermining the search for effective treatments. The level of co‐occurring anxiety has been used to identify “primary” (lower anxiety) versus “secondary” (higher anxiety ...

A placebo-controlled trial of folic acid and betaine in identical twins with Angelman syndrome. [PDF]

open access: yes, 2019
BackgroundAngelman syndrome (AS) is a neurodevelopmental disorder that is caused by maternal genetic deficiency of a gene that encodes E6-AP ubiquitin-protein ligase (gene symbol UBE3A) mapping to chromosome 15q11-q13.

Multivariate maternal effects across the internalizing–externalizing spectrum in childhood: results from the Norwegian mother, father, and child cohort study

open access: yesJournal of Child Psychology and Psychiatry, EarlyView.
Background From a functionalist perspective, parenting behaviors have adaptive functions and are partly expressions of genetic variation. Maternal genes that have effects on children are often referred to as indirect maternal genetic effects. Indirect genetic effects provide a means for measuring the role of parenting without the need for specifying ...

Anxiety-related experience-dependent white matter structural differences in adolescence: A monozygotic twin difference approach

open access: yesScientific Reports, 2017
Anxiety is linked to deficits in structural and functional connectivity between limbic structures and pre-frontal cortices. We employed a monozygotic (MZ) twin difference design to examine the relationship between structural characteristics of the ...
