Definitions vary on what constitutes sexual and/or physical abuse, and scholars have debated on which methods might yield the most accurate response rates for capturing this sensitive information. Although some studies suggest respondents prefer methods that provide anonymity, previous studies have not utilized high-risk or stigmatized populations. In this article, the authors report on serendipitous findings when using two methods to assess the past year incidence of sexual and physical violence among women involved in the criminal justice system. Women who participated in an anonymous survey reported higher physical and sexual victimization than did the women who were interviewed, even though the questions were identical. Implications of the findings are discussed. (Contains 2 tables.)
