The discovery of acquaintance rape: the salience of methodological innovation and rigor.

Over the past 20 years, research has uncovered the many types of sexual victimizations women experience. Findings regarding the victim-offender relationship in such incidents have undoubtedly been among the most striking. Particularly salient is the revelation that the sexual abuse of and violence against women-including rape-most often are perpetrated not by a stranger but by someone known to the victim. Without the innovation and implementation of victimization surveys with behaviorally specific questions, this knowledge may have remained unknown.

In this article, we address these issues related to key developments in sexual victimization research.
