Dissertation/Thesis Abstract

The moderating effect of intergroup versus interpersonal context on the relationship between collective rumination and aggression
by Ellison, Jennifer M., M.A., California State University, Long Beach, 2016, 98; 10134007
Abstract (Summary)

Previous research has demonstrated that collective rumination, or a group discussion about a negative event, leads to greater aggression than either individual rumination or a distraction task. The goal of the current study was to (a) determine if intergroup versus interpersonal provocation moderates the ability of collective rumination to augment aggression and (b) assess the process by which collective rumination impacts aggressive behavior. Participants were randomly assigned to either the intergroup or interpersonal conditions and then ruminated either individually or collectively. Collective rumination increased aggression but the magnitude of this effect did not differ for the intergroup and interpersonal conditions. The process by which collective rumination increased aggression, however, did differ across condition with affective reaction to the provocation mediated the effect in the interpersonal condition whereas general aggressive affect and identity fusion were mediators for the intergroup condition. Potential implications of these findings for aggression reduction will be discussed.
