Impulse-control disorders in college students.

We investigated impulse-control disorders (ICDs), alcohol use and outcome expectancies in students (n=571, 63.9% female, age: M=21.7) using questionnaires. Twenty (3.5%) were positively screened for lifetime ICDs, mostly males (n=16, 80%). Disorder-specific rates ranged between 0 and 1.2%. Differences in alcohol use and expectancies between ICDs and controls did not reach significance.
