September 11 attacks: prior interpersonal trauma, dysfunctional cognitions, and trauma response in a midwestern university sample.

Undergraduate college students (N = 133) were assessed for posttrauma and depressive symptomatology, posttrauma cognitions, and previous traumatic experiences 1 month after the September 11 attacks in the United States. Negative beliefs regarding oneself and the world mediated the relationship between prior interpersonal trauma and acute trauma symptoms. Acute depression acted as a mediator between prior interpersonal trauma and negative cognitions of oneself and self-blame cognitions. The results suggest that even in a nonclinical, nontreatment seeking college sample, prior traumatic events can play an important role in an individual's short-term adjustment following indirect exposure to a significant trauma. The differential relationship of negative beliefs on acute trauma symptoms and depression is discussed.
