Building upon findings from a previous study which found that 63% of campus rapists were repeat offenders, a new study has found that “only” one-quarter of college men admit to rape more that once. However, one in ten college men admitted to rape at some point. The study has limitations but it’s telling nonetheless. From feministing:
In 2002, a ground-breaking study found that the majority (63 percent) of campus rapists were serial offenders, with each repeat perpetrator committing six rapes on average. David Lisak’s finding has remained a major talking point among lawmakers, reporters, and activists ever since.Nine in 10 rapes are perpetrated by repeat offenders. If we can only catch those criminals and incarcerate them, we’ll dramatically reduce violence in our communities.
This week, a new study published in JAMA Pediatrics challenged Lisak’s conclusion that most college rapists are repeat perpetrators. The study found that of the men who reported committing rape, only some 25 percent said they had done so over multiple years — in comparison with Lisak’s 63 percent. It also found that 10.8 percent of male college students — or more than one in 10 — reported having committed rape, in contrast with only 6 percent in Lisak’s study.
Of course, there are limitations to the new study: it was conducted at two universities in the southeast, the vast majority of participants were white, and the sample size was small. And while the study suggests that perpetration patterns over time in an individual’s life aren’t as straightforward as Lisak’s findings suggested, it tells us little about perpetration patterns in a given year. As RTI International research sociologist Christine Lindquist explains: “I definitely think that this study helps contribute to our understanding of the consistency of rape behavior among men from one year to the next. But not necessarily whether a small number of men account for the vast majority of rapes on a given campus…. Someone who only committed rape during his freshman year (but not any other years) could have raped 10 people (or one person 10 times) and still not be identified in the ‘increasing’ trajectory.”

Abstract below and rest of stud here:
Importance Rape on college campuses has been addressed recently by a presidential proclamation, federal legislation, advocacy groups, and popular media. Many initiatives assume that most college men who perpetrate rape are serial rapists. The scientific foundation for this perspective is surprisingly limited.
Objective To determine whether a group of serial rapists exists by identifying cohesive groups of young men, indicated by their trajectories of rape likelihood across high school and college.
Design, Setting, and Participants Latent class growth analysis of the 2 largest longitudinal data sets of adolescent sexual violence on college campuses using 2 distinct groups of male college students. The first group was used for derivation modeling (n = 850; data collected from August 1990 through April 1995) and the second for validation modeling (n = 795; data collected from March 2008 through May 2011). Final data analyses were conducted from February 16, 2015, through February 20, 2015.
Main Outcomes and Measures Rape perpetration assessed using the Sexual Experiences Survey.
Results Across samples, 177 of 1645 participants (10.8%) reported having perpetrated at least 1 rape from 14 years of age through the end of college. A 3-trajectory model best fit both the derivation and validation data sets. Trajectories reflected low or time-limited (91.7% of participants), decreasing (5.6%), and increasing (2.7%) rape patterns. No consistently high trajectory was found. Most men who perpetrated a rape before college were classified in the decreasing trajectory. During college, the increasing trajectory included 19 men (20.9%) who reported having perpetrated a rape, the decreasing trajectory included 25 men (27.5%), and the low or time-limited included 47 men (51.6%). No participant in the low or time-limited trajectory reported perpetrating a rape during more than 1 period. Most men (68 [74.7%]) who committed college rape only perpetrated rape during 1 academic year.
Conclusions and Relevance Although a small group of men perpetrated rape across multiple college years, they constituted a significant minority of those who committed college rape and did not compose the group at highest risk of perpetrating rape when entering college. Exclusive emphasis on serial predation to guide risk identification, judicial response, and rape-prevention programs is misguided. To deter college rape, prevention should be initiated before, and continue during, college. Child and adolescent health care professionals are well positioned to intervene during the early teenage years by informing parents about the early onset of nonconsensual sexual behavior.
