Rumination And Pessimistic Certainty As Mediators Of The Relation Between Lifetime Suicide Attempt History And Future Suicidal Ideation
ARCHIVES OF SUICIDE RESEARCH(2013)
Abstract
This study examined whether rumination and certainty about pessimistic future-event predictions (P-Certainty) would mediate the relation between lifetime suicide attempt history and future suicidal ideation. Young adults, ages 18-25 (N=143), with a suicide attempt history (n=32) or no previous suicide attempt history (n=111) at baseline, were followed up 2-3 years later and completed measures of rumination, depressive symptoms, hopelessness, suicidal ideation, and pessimistic future-event certainty. Lifetime suicide attempts at baseline were associated with higher suicidal ideation at follow up, and this relation was mediated by rumination and P-Certainty. Suicide attempters may be vulnerable to later ideation due to higher levels of rumination and also certainty in their pessimistic future expectations.
