<b>MOMENTARY ASSESSMENT OF THE EFFECTS OF INDIVIDUAL DIFFERENCES ON AGGRESSION</b>

<p dir="ltr">This study examined important risk factors for aggression that have had little to no examination in relation to aggression using repeated, real-time, situation-based measurement and have not been pitted against each other to compare their effect on momentary aggression and how they might work through momentary negative affect. Using an experience-sampling approach, the current study examined the effects of antagonistic triad traits, criminogenic thinking, history of criminal and antisocial behavior, and momentary negative affect on aggression in the context of interpersonal interactions. Data were collected from 69 undergraduate students who were instructed to complete three prompts a day for ten consecutive days. Results revealed that negative affect consistently exhibited both within- and between-person effects on aggression. History of criminal and antisocial behavior, as well as trait impulsivity, predicted aggression. Impulsivity also moderated the effect of occasion-level negative affect on aggression. The results illustrate how integrating momentary data with dispositional risk factors can help clarify the contexts in which aggression can likely occur and for whom.</p>
