One hundred and eighty six adult heterosexual females enrolled in colleges across the United States were sampled to determine the influence of personality and coping variables on female Intimate Partner Aggression (IPA). The research instruments administered included online versions of: the Revised-Conflict Tactics Scale (CTS-2; Straus, Hamby, Boney-McCoy, & Sugarman, 1996), which explored female Intimate Partner Psychological Aggression and Physical Assaultiveness; the International Personality Item Pool (IPIP; Goldberg, 1999), which measured the personality trait of Neuroticism; and the Coping Resources Inventory for Stress-Short Form (CRIS-SF; Matheny, Curlette, Aycock, Pugh, & Taylor, 2007), which assessed the coping resources of Tension Control and Social Support, and provided an overall Coping resource score called Coping Resource Effectiveness (CRE). The role of Neuroticism was highlighted. Neuroticism, but not CRE or specific coping resources, was predictive of Psychological Aggression in females. Neither CRE nor Neuroticism was a significant predictor of Physical Assaultiveness. Implications for reducing psychological aggression in intimate partner relationships were offered.
