The occurrence of violence in lesbian relationships challenges societal stereotypes of women and traditional, sociopolitical theories of domestic violence. This article proposes that a multidimensional theory of partner abuse, which incorporates an emphasis on individual personality dynamics, is needed to more fully understand the heterogeneity of batterers. The relationship between psychopathology, sociocultural factors, and battering in lesbian relationships is examined and dynamics related to the borderline and narcissistic disorders are highlighted. In order to improve our understanding of domestic violence and provide effective treatment, we must continue to pursue critical thinking and research regarding the role of personality dynamics, and the relationship between these dynamics and other variables.
