Social inequality in youth violence: The role of heavy episodic drinking.

The findings lend support to both the differential exposure hypothesis and to the differential vulnerability hypothesis as well as the hypothesis of an enhancing effect of impulsivity on the HED-violence association. The SES difference in youth violence can be accounted for by: (i) an elevated prevalence of HED in low-SES groups; and (ii) a stronger than average link between HED and violence in low-SES groups due to their higher than average impulsivity score.
