Suicidality and cognitive vulnerability to depression among college students: a prospective study.
Using a behavioral high-risk two-site prospective design, we tested the cognitive vulnerability hypotheses about suicidality. Consistent with prediction, the high cognitive risk (HR) participants were more likely than the low cognitive risk (LR) participants to exhibit suicidality, measured by both structured diagnostic interview and questionnaire self-report, during the 2 1/2 year prospective follow-up period. Moreover, when the prospective period was examined as a whole, the mediation hypothesis derived from the cognitive theories was strongly supported. Hopelessness appeared to mediate the obtained relationship between cognitive vulnerability and suicidality. Finally, the obtained relationship between cognitive vulnerability and suicidality was not mediated by other hypothesized risk factors for suicidality not specified in the cognitive theories, such as past suicidality, personal history of depressive disorders, borderline and antisocial personality dysfunction, and parental history of depression.
