False allegations of sexual assualt: an analysis of ten years of reported cases.

One of the most controversial disputes affecting the discourse related to violence against women is the dispute about the frequency of false allegations of sexual assault. In an effort to add clarity to the discourse, published research on false allegations is critiqued, and the results of a new study described. All cases (N = 136) of sexual assault reported to a major Northeastern university over a 10-year period are analyzed to determine the percentage of false allegations. Of the 136 cases of sexual assault reported over the 10-year period, 8 (5.9%) are coded as false allegations. These results, taken in the context of an examination of previous research, indicate that the prevalence of false allegations is between 2% and 10%.

Repeat rape and multiple offending among undetected rapists.

Pooling data from four samples in which 1,882 men were assessed for acts of interpersonal violence, we report on 120 men whose self-reported acts met legal definitions of rape or attempted rape, but who were never prosecuted by criminal justice authorities. A majority of these undetected rapists were repeat rapists, and a majority also committed other acts of interpersonal violence. The repeat rapists averaged 5.8 rapes each. The 120 rapists were responsible for 1,225 separate acts of interpersonal violence, including rape, battery, and child physical and sexual abuse. These findings mirror those from studies of incarcerated sex offenders (Abel, Becker, Mittelman, Cunningham-Rathner, Rouleau, & Murphy, 1987; Weinrott and Saylor, 1991), indicating high rates of both repeat rape and multiple types of offending. Implications for the investigation and prosecution of this so-called "hidden" rape are discussed.
