The familiality of suicidal ideation was examined in the subjects who participated in the Cardiff Depression Study, namely, 108 depressed probands, their nearest-aged siblings, & 105 healthy control subjects & their siblings. The study showed that 66% of depressed subjects had experienced suicidal ideation in the week prior to the interview & that this was significantly associated with recurrent illness. Suicidal ideation was not shown to be familial. However, somewhat surprisingly, 6% of healthy, never-depressed subjects admitted to having had transient suicidal thoughts. Suicidal ideation was significantly associated with high neuroticism & psychoticism scores & severe threatening life events. (14 refs.)
