This issue represents our efforts to apply a feminist or gender lens to the research on violence in intimate relationships and to forward our understanding of gender and interpersonal violence. The paper introduces the articles in this special issue on "Understanding Gender and Intimate Partner Violence" within a framework of theoretical and methodological issues in feminist research. The current articles are viewed as contributing to our understanding of gender and interpersonal violence: by investigating patterns of interpersonal violence; by examining interpersonal violence with the context of lifespan and culture; by positing or testing theoretical models for gender and interpersonal violence; and by arguing for methodological or conceptual advances in the field. KEY WORDS: feminist research; intimate abuse; partner violence; interpersonal violence; women's use of violence; gender.Many feminist psychologists and sociologists are committed to feminist research in order to improve the lives and experiences of women or to work for gender equity. As more research has been conducted and published in the area of interpersonal violence, we might pause to ask ourselves: What have we learned about gender and the use of interpersonal violence in the past decades? How has our research benefited women? Have we developed theoretical perspectives or interventions? Have we advanced our understanding of women? Of gender? Of aggression? Of interpersonal violence?Evidence of women's use of violence and conclusions regarding gender symmetry has accumulated since the mid 1970s. For example, using quantitative data from a randomized national sample, Brush (1990) found no significant differences between men and women in committing violent acts of hitting, shoving or throwing objects at one's partner. Archer's (2000) review indicated that overall, women are slightly but significantly more likely to use one or more acts of physical aggression against their heterosexual partner and to use aggression more frequently than men. In Archer's (2002) second meta-analysis, both men and women reported acts of aggression against their partner across the entire range of aggressive behaviors in terms of seriousness, but women were more likely to commit low levels of violence, whereas men were more likely than women to engage in serious violence. Some studies published since Archer's meta-analysis confirmed the finding that more women than men engage in physical aggression toward a partner (e.g., Hird, 2000).These sex-symmetry findings are seen as contradicting feminist conceptions of intimate abuse as a problem of gender and power (Currie, 1998). Frieze (2000 has written about women's use of violence in interpersonal relationships, and has received some hostility and resistance from colleagues because of this (Frieze, personal communication). For some time it appeared that many feminist researchers preferred to document the negative consequences of male violence toward women, and to ignore the question of gender symmetry or differences in violen...
