Lifetime acute suicidal affective disturbance symptoms account for the link between suicide-specific rumination and lifetime past suicide attempts

摘要

Background: Suicide-specific rumination, defined as rumination about one's suicidal thoughts, intentions, and plans, and Acute Suicidal Affective Disturbance (ASAD) have each been proposed as relevant and proximal predictors of suicidal behavior. The purpose of the current study was to examine relations between suicide specific rumination, ASAD, and previous number of lifetime suicide attempts, particularly whether ASAD accounted for the association between suicide-specific rumination and previous lifetime suicide attempts.
