Non-random mating patterns within and across education and mental and somatic health.

Partners resemble each other in health and education, but studies usually examine one trait at a time in established couples. Using data from all Norwegian first-time parents (N = 187,926) between 2016-2020, we analyse grade point average at age 16, educational attainment, and medical records of 10 mental and 10 somatic health conditions measured 10 to 5 years before childbirth. We find stronger partner similarity in mental (median r = 0.

Associations between parental psychopathology and youth functional emotion regulation brain networks.

Parental mental health is associated with children's emotion regulation (ER) and risk for psychopathology. The relationship between parental psychopathology and children's functional ER networks and whether connectivity patterns mediate the relationship between parent and youth psychopathology remains unexplored. Using resting-state functional magnetic resonance imaging data from the Adolescent Brain Cognitive Development Study (N = 4202, mean age = 10.

Most people do not attribute their burnout symptoms to work.

A prevailing belief among researchers is that burnout is a work-specific syndrome induced by intractable job stress. The validity of this belief, however, remains unclear. This cross-sectional study compared burnout with two general conditions, nonspecific psychological distress (NSPD) and exhaustion, in terms of (a) causal attributions to work and (b) associations with 11 job variables (e.

Familial confounding or measurement error? How to interpret findings from sibling and co-twin control studies.

Epidemiological researchers often examine associations between risk factors and health outcomes in non-experimental designs. Observed associations may be causal or confounded by unmeasured factors. Sibling and co-twin control studies account for familial confounding by comparing exposure levels among siblings (or twins).

Individual differences in internalizing symptoms in late childhood: A variance decomposition into cortical thickness, genetic and environmental differences.

The brain undergoes extensive development during late childhood and early adolescence. Cortical thinning is a prominent feature of this development, and some researchers have suggested that differences in cortical thickness may be related to internalizing symptoms, which typically increase during the same period. However, research has yielded inconclusive results.
