Anxiety and depressive symptoms in childhood - a genetic study of comorbidity

Article Abstract:

Researchers used genetic strategies to investigate whether anxiety and depressive symptoms frequently co-occur because they have the same etiology. They used bivariate genetic analysis to examine maternal ratings of anxiety and depression in 172 pairs of twins in the age group 8 to 16 years. The results revealed that a common genetic cause can explain most of the covariation between the two sets of symptoms, and that environmental factors also explain some of the covariation. However, specific genetic factors also have a small influence on depressive symptoms.

Life events and depressive symptoms in childhood - shared genes or shared adversity? a research note

Article Abstract:

A study was conducted to analyze the influences of genetic and environmental factors on the relationship between life events and depressive symptoms in childhood using bivariate genetic analyses. An altered version of the Life Events Checklist was utilized to evaluate life events while the Twin Similarity Questionnaire was used to determine between monozygotic and dizygotic twins. Results indicated that the association between life events and depressive symptoms correlated with familial factors.

Are anxiety symptoms in childhood heritable?

Article Abstract:

A study of the attitudes of parents and their 376 twin pair offspring on the transmission of childhood anxiety revealed parental reports as suggestive of anxiety symptoms in childhood to be heritable. In sharp contrast, self-evaluation reports of the children revealed their perceptions of shared environment factors as the main transmitters of anxiety symptoms.
