The Bureau of Justice Statistics' (BJS) National Crime Victimization Survey (NCVS) measures the rates at which Americans are victims of crimes, including rape and sexual assault, but there is concern that rape and sexual assault are undercounted on this survey. BJS asked the National Research Council to investigate this issue and recommend best practices for measuring rape and sexual assault on their household surveys. Estimating the Incidence of Rape and Sexual Assault concludes that it is likely that the NCVS is undercounting rape and sexual assault. The most accurate counts of rape and sexual assault cannot be achieved without measuring them separately from other victimizations, the report says. It recommends that BJS develop a separate survey for measuring rape and sexual assault. The new survey should more precisely define ambiguous words such as "rape," give more privacy to respondents, and take other steps that would improve the accuracy of responses. Estimating the Incidence of Rape and Sexual Assault takes a fresh look at the problem of measuring incidents of rape and sexual assault from the criminal justice perspective. This report examines issues such as the legal definitions in use by the states for these crimes, best methods for representing the definitions in survey instruments so that their meaning is clear to respondents, and best methods for obtaining as complete reporting as possible of these crimes in surveys, including methods whereby respondents may report anonymously. Rape and sexual assault are among the most injurious crimes a person can inflict on another. The effects are devastating, extending beyond the initial victimization to consequences such as unwanted pregnancy, sexually transmitted infections, sleep and eating disorders, and other emotional and physical problems. Understanding the frequency and context under which rape and sexual assault are committed is vital in directing resources for law enforcement and support for victims. These data can influence public health and mental health policies and help identify interventions that will reduce the risk of future attacks. Sadly, accurate information about the extent of sexual assault and rape is difficult to obtain because most of these crimes go unreported to police. Estimating the Incidence of Rape and Sexual Assault focuses on methodology and vehicles used to measure rape and sexual assaults, reviews potential sources of error within the NCVS survey, and assesses the training and monitoring of interviewers in an effort to improve reporting of these crimes.

"Sexual assault continues to be a pervasive problem, both for society in general and within the military community. To assist the Air Force in its continued efforts to combat sexual assault within its ranks, we reviewed the existing empirical literature on the characteristics and behaviors of adult perpetrators who commit sexual assault against other adults. Our search was not limited to studies of military populations. While a vast majority of the existing literature has focused on sole male perpetrators who assault female victims, we identified some research on other types of perpetrators, including female sexual assault perpetrators, men who perpetrate assault against other men, and perpetrators who participate in group sexual assault. This body of research indicates that adult perpetrators are diverse in terms of their demographics, background characteristics, and motivations. Moreover, research indicates that sexual assault perpetration is likely influenced by a combination of factors, including an individual's developmental and family history; his or her personality, including attitudes/cognitions; and environmental factors, including peer attitudes and alcohol consumption. The complexity of factors that influence sexual assault perpetration and the multiple pathways that lead to an attack make it difficult to predict whether an individual is prone to commit sexual assault. While predicting sexual assault perpetration is problematic, we identified a number of factors related to perpetration that may be relevant for intervention efforts and offer recommendations for the Air Force"--Publisher's web site.

This report summarises current knowledge about sexual violence in Australia, including existing data on sexual offenders; some of the programs aimed at preventing sexual violence and treating both sexual violence victims and offenders; and areas where sexual violence policies and programs could be improved. The report also considers the consequences of sexual violence, including physical, social, economic and psychological effects. It considers the long term and special effects that the experience of sexual violence can have on different victims, including children, males, Indigenous Australians, people from non English speaking backgrounds, and the intellectually disabled.

Violence against women is one factor in the growing wave of alarm about violence in American society. High-profile cases such as the O.J. Simpson trial call attention to the thousands of lesser-known but no less tragic situations in which women's lives are shattered by beatings or sexual assault. The search for solutions has highlighted not only what we know about violence against women but also what we do not know. How can we achieve the best understanding of this problem and its complex ramifications? What research efforts will yield the greatest benefit? What are the questions that must be answered? Understanding Violence Against Women presents a comprehensive overview of current knowledge and identifies four areas with the greatest potential return from a research investment by increasing the understanding of and responding to domestic violence and rape: What interventions are designed to do, whom they are reaching, and how to reach the many victims who do not seek help. Factors that put people at risk of violence and that precipitate violence, including characteristics of offenders. The scope of domestic violence and sexual assault in America and its conequences to individuals, families, and society, including costs. How to structure the study of violence against women to yield more useful knowledge. Despite the news coverage and talk shows, the real fundamental nature of violence against women remains unexplored and often misunderstood. Understanding Violence Against Women provides direction for increasing knowledge that can help ameliorate this national problem.
