If found to generalize to other campus populations, the role of hooking up in sexual assault should be added to systems-based models of sexual assault (e.g.,Heise, 1998) and to educational prevention programs. (PsycINFO Database Record

Previous research has demonstrated a significant association between alcohol and aggression. However, the precise mechanisms underlying this relationship have yet to be fully elucidated. In the present study, we examined alcohol's effects on an attentional bias toward aggressogenic cues as the first step in a possible mediation model of alcohol-facilitated intimate partner aggression. More specifically, we tested an interactive effect of problematic alcohol use and acute alcohol intoxication on an attentional bias toward anger words. Participants in this study were 249 male and female heavy drinkers from the community with a history of past-year intimate partner aggression perpetration who participated in an alcohol-administration laboratory study assessing the effect of alcohol intoxication on cognitive biases. Multiple linear regression was used to test the proposed moderation model. Acute alcohol intoxication moderated the effect of problematic alcohol use on an attentional bias toward anger, with this effect being stronger for individuals in the alcohol compared to no-alcohol control condition. These findings suggest that problematic drinkers may be more likely to attend to aggressogenic stimuli while acutely intoxicated, relative to when they are sober.

Objective: Previous research has demonstrated a significant association between trauma and intimate partner aggression (IPA) perpetration. However, the precise mechanisms underlying this relationship have yet to be fully elucidated. In the present study, we examined the impact of several key factors implicated in Ehlers and Clark’s (2000) cognitive model of trauma (i.e., trauma cognitions, anger, hostility, and rumination) on IPA perpetration. Method: Participants in this study were 271 male and female heavy drinkers at high risk for IPA from the community who completed measures of dysfunctional posttraumatic cognitions, dispositional rumination, trait anger and hostility, and IPA perpetration. A moderated mediational model was tested to determine how these variables interact to predict IPA perpetration. Results: Results indicated that anger and hostility mediated the effect of negative cognitions about the world on IPA perpetration, with this indirect effect being stronger for individuals with higher levels of rumination. Conclusion: These findings suggest that cognitive and affective processes that may result from trauma exposure are associated with IPA and should be targeted in prevention and intervention programs for individuals at risk for perpetration.

In this multisite study, we examined whether aggressive cognitions and facial displays of negative affect and anger experienced during provocation mediated the association between alcohol intoxication and intimate-partner aggression (IPA). Participants were 249 heavy drinkers (148 men, 101 women) with a recent history of IPA perpetration. Participants were randomly assigned to an alcohol or no-alcohol control-beverage condition and completed a shock-based aggression task involving apparent provocation by their intimate partner. During provocation, a hidden camera recorded participants’ facial expressions and verbal articulations, which were later coded using the Facial Action Coding System and the Articulated Thoughts in Simulated Situations paradigm. Results indicated that the positive association between alcohol intoxication and partner-directed physical aggression was mediated by participants’ aggressive cognitions but not by negative affect or anger facial expressions. These findings implicate aggressogenic cognitions as a mediating mechanism underlying the association between the acute effects of alcohol and IPA perpetration.
