Impulsivity and alcohol use are also closely tied to violence and aggression. Alcohol dependence is associated with an increased risk for aggressive behavior, which may be related to certain forms of impulsivity. This association may either result from pre-existing impulsive tendencies, or it may result from—or be exacerbated by—alcohol use, which further increases the risk of aggression. Dom, Hulstijn, & Sabbe (2006) compared impulsivity, sensation seeking and aggression in early- and late-onset alcohol dependent individuals. Those with early onset scored higher on measures of aggression than those with late onset, and further, the groups differed on questionnaire measures of impulsivity even after controlling for the effect of aggressiveness (Dom et al., 2006). Bjork and colleagues (2004) examined these relationships using behavioral measures of impulsivity, comparing detoxified alcohol dependent individuals (n = 130) to healthy controls (n = 41) on behavioral measures including two risk-taking tasks designed by the authors, a delay discounting task, and self-report measures (SSS, BIS and a self-report measure of aggression). Compared to the healthy controls, alcohol dependent individuals demonstrated poorer response inhibition, higher rates of delay
