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

CONCLUSIONS: The transmission of suicide attempt across generations is moderately strong and arises equally from genetic and rearing effects. Parental psychiatric illness explains almost half of the genetic transmission of suicide attempt but none of the rearing effect. Suicide death is modestly transmitted across generations, probably via genetic effects, although rearing may play a role. While suicide attempt and suicide death share a substantial proportion of their hereditary risk, they do not, from a genetic perspective, simply reflect milder and more severe forms of the same diathesis.
