Abstract The relationship between subjective wellbeing (SWB) and self-reported sleep problems was investigated in a cohort of Norwegian twins aged 18 to 31 years. Questionnaire data from 8045 same- and opposite-sex twins were analyzed using structural equation modeling to explore the relative effects of genetic and environmental influences on phenotypic variance and covariance. Special attention was paid to sex-specific effects. The correlation between the phenotypes was estimated to be −.43… 

Associations of sleep with psychological problems and well‐being in adolescence: causality or common genetic predispositions?

The findings suggest that sleep quality, rather than sleep duration, should be the primary target for prevention and intervention, with possible effect on psychological functioning in adolescents.

Psychological well-being (PWB): a natural life outlook? An Italian twin study on heritability of PWB in young adults

A twin analysis of PWB measured by the Ryff's Scales of Psychological Well-Being found that both genes and non-shared environment play a role in individual differences.

Happiness in Behaviour Genetics: An Update on Heritability and Changeability

In this paper we summarize recent behaviour genetic findings on happiness measured as life satisfaction (LS) and subjective wellbeing (SWB) and discuss important implications pertaining to stability

Genetics of Wellbeing and Its Components Satisfaction with Life, Happiness, and Quality of Life: A Review and Meta-analysis of Heritability Studies

A more robust estimate of the relative influence of genetic effects on wellbeing is provided using a sample size weighted average heritability analysis of 30 twin-family studies on wellbeing and satisfaction with life.

Happiness in Behaviour Genetics: Findings and Implications

A number of behaviour genetic studies have shown variation in happiness to be influenced by genes, and indicated that long-term happiness is predominantly caused by genes. To policy makers and

Exploring the Relative Contributions of the Strength and Distress Components of Dual-Factor Complete Mental Health Screening

Early school-based mental health screeners were informed by a deficit paradigm that aimed to identify psychological distress symptoms. In comparison, following a whole-child perspective, a

Healthier and Happier? A 3-Year Longitudinal Investigation of the Prospective Associations and Concurrent Changes in Health and Experiential Well-Being

Findings suggest that health and well-being change together in processes that unfold relatively quickly, underscoring the importance of using appropriate longitudinal statistical models.

The Nature and Nurture of Wellbeing

Psychological research has contributed to considerable progress in understanding and treating mental illness, however, we know much less about mental health and wellbeing, and how we can promote



Happiness and health: environmental and genetic contributions to the relationship between subjective well-being, perceived health, and somatic illness.

Results support a differentiated view of SWB-health relations, and imply that both genes and environment play important roles in the associations between well-being and health.

Direction of Causation Modeling Between Cross-Sectional Measures of Parenting and Psychological Distress in Female Twins

DOC modeling between latent constructs of parenting and psychological distress revealed that a model which specified recollected parental behavior as the cause of psychological distress provided a better fit than a models which specified psychological distress as thecause of recollected parent behavior.

Insufficient sleep--a population-based study in adults.

Insufficient sleep is a common and long-standing condition, most strongly associated with sleep/wake variables, and one third of the liability to it is attributed to genetic influences.

Genetic and environmental determination of human sleep.

Self-reported sleep data from 2238 monozygotic and 4545 dizygotic adult twin pairs indicated a significant hereditary effect on sleep length and sleep quality and significant heritability estimates were found for all groups except women living together.

Evidence for genetic influences on sleep disturbance and sleep pattern in twins.

There was no evidence for a decline in the importance of genetic predisposition with age and short-term environmental fluctuations accounted for as much as 30% of the variance, and more stable nonfamilial environmental effects accounted for the remainder.

Correlates of global sleep dissatisfaction in the German population.

This study confirms that GSD is a better indicator of an underlying pathology than the classical insomnia symptoms alone: compared to insomniac subjects without GSD, subjects with GSD were two times more likely to report excessive daytime sleepiness, and eight timesMore likely to have a diagnosis of sleep or mental disorder.

Effects of lifestyle, personality, symptoms of anxiety and depression, and genetic predisposition on subjective sleep disturbance and sleep pattern

There was little evidence for genetically determined differences in sensitivity to the lifestyle variables, and much of the association between sleep disturbance and lifestyle appeared to be explained by separate effects of personality and symptoms of anxiety and depression on sleep and lifestyle.

Sex‐specific effects for body mass index in the new Norwegian twin panel

Results from the most parsimonious model indicated that the genes contributing to variation in BMI are not identical for men and women; rather, some genetic effects were shared by the sexes and some were unique to each sex.

Gender differences in the symptoms of major depression in opposite-sex dizygotic twin pairs.

Female twins reported experiencing significantly more fatigue, hypersomnia, and psychomotor retardation during the most severe major depressive episode, whereas male twins reported more insomnia and agitation.
