Abstract

Suicide is a leading cause of death among older adolescents and young adults; however, few studies have prospectively examined risk for suicidal ideation. The present study in older adolescents and young adults investigated whether two personality traits previously implicated in risk for suicidal ideation, neuroticism and extraversion, as well as certain aspects of interpersonal functioning, prospectively predicted endorsement of suicidal ideation during depressive episodes. Participants (n=117) are a subset of the Northwestern-UCLA Youth Emotion Project sample, which started with a group of high school juniors oversampled for high neuroticism. Baseline interpersonal functioning was measured using the Life Stress Interview. Baseline personality trait composite scores were created from multiple inventories. Depressive disorders and suicidal ideation were assessed at the baseline and three annual follow-up interviews using the SCID. Cox regression was employed to predict suicidal ideation during depressive episodes diagnosed at any follow-up interview. Results showed that baseline extraversion inversely predicts suicidal ideation in males only, and that baseline interpersonal problems in one's social circle, regardless of gender, predict suicidal ideation during depressive episodes.
