The Sources of Parent-Child Transmission of Risk for Suicide Attempt and Deaths by Suicide in Swedish National Samples.

ABSTRACT:

Objective

The authors aimed to clarify the sources of parent-child transmission for suicide attempt and death by suicide.

Methods

Three sources of parent-child resemblance (genes plus rearing, genes only, and rearing only) were examined in parents and offspring from four family types from Swedish national samples: intact nuclear families, families with a not-lived-with biological father, families with a stepfather, and adoptees and their biological and adoptive parents. Parent-child resemblance was assessed primarily by tetrachoric correlation.

Results

For suicide attempt to suicide attempt transmission, best-estimate tetrachoric correlations for genes plus rearing, genes only, and rearing only were 0.23 (95% CI=0.23, 0.24), 0.13 (95% CI=0.11, 0.15), and 0.14 (95% CI=
