The extant adoption, twin, and family studies of suicide and suicidal behavior are reviewed.

Adoption and twin studies show that familial transmission of suicidal behavior is partly
attributable to genetic factors. Transmission of suicidal behavior is mediated by transmission …

Background Although adoption, twin, and family studies have shown that suicidal behavior
is familial, the risk factors for familial transmission from parent to child remain unclear …

suicidal ideation and suicide attempts among adult offspring in a general community …

There are five lines of evidence about genetic factors in suicide. This paper will review the
clinical, twin, Iowa-500, Amish, and Copenhagen adoption studies, all of which provide …

the relatives of suicide victims, it is unclear if this is attributable merely to increased familial …

Objective: The authors sought to identify clinical predictors of new-onset suicidal behavior in
children of parents with a history of mood disorder and suicidal behavior. Method: In a …
