Prospective risk factors for subsequent exposure to potentially traumatic events.

In a sample of 1528 college students, we examined (1) whether several risk factors prospectively predicted exposure to potentially traumatic events (PTEs) over a 2-month period and (2) whether dependent events (i.e., those more likely to depend upon one's behavior or characteristics) and independent events were predicted by different risk factors. Logistic regression analyses indicated that overall subsequent PTE exposure was higher for women, those with more previous PTEs, and those who engaged in more binge drinking. Female gender and previous PTE exposure also predicted exposure to independent events. Subsequent dependent PTE exposure was predicted by more previous PTEs and binge drinking, and was somewhat higher in ethnic minority students. Implications for prevention efforts are discussed.
