Negative attributional style for interpersonal events and the occurrence of severe interpersonal disruptions as predictors of self-reported suicidal ideation.

We applied the hopelessness theory of depression to suicidal symptoms: 203 undergraduates completed questionnaires on attributional style, negative life events, hopelessness, and suicidal symptoms at one point in time and again 10 weeks later. Consistent with prediction, the combination of a negative attributional style for interpersonal events and the occurrence of such events were prospectively related to increases in self-reported suicidality over the course of the 10-week study. These findings displayed specificity with respect to interpersonal versus achievement-related styles and events. Contrary to hypothesis, hopelessness did not mediate the relation between the Attributional style x Stress interaction and the increases in self-reported suicidality.
