Previous studies on multiple perpetrator rapes have shown that male sexual offenders who commit their offense alone differ on offender, offense, and victim characteristics from those who commit their offense in duos and 3+ groups. For the current study, 246 female sexual offenders have been studied regarding their co-offending pattern and the differences in offender, offense, and victim characteristics. Significant differences between solo (n = 73), duos (n = 146), and 3+ group offenders (n = 27) were found for the age at the first conviction, age at the time of the index offense, performed sexual acts, physical and verbal violence, victim gender, victim relationship, victim age, and location where the abuse took place. There were four indicators that could predict the assault type. Co-offenders were more likely than solo offenders to perform penetration on a female, intrafamilial victim who they assaulted indoors. These results have implications for interventions with offenders and criminal justice authorities.

女性罪犯实施的多起强奸：单人、双人和 3+ 团体罪犯的比较

先前关于多起强奸案的研究表明，单独犯罪的男性性犯罪者在犯罪者、犯罪行为和受害者特征上与双人和 3+ 群体犯罪的男性性犯罪者不同。在目前的研究中，研究了 246 名女性性犯罪者的共同犯罪模式以及犯罪者、犯罪者和受害者特征的差异。单人（n = 73）、双人（n = 146）和 3+ 组犯罪者（n = 27）在首次定罪时的年龄、指数犯罪时的年龄、进行性行为、身体和语言暴力、受害者性别、受害者关系、受害者年龄和虐待发生地点。有四个指标可以预测攻击类型。与单独犯罪者相比，共同犯罪者更有可能对他们在室内袭击的女性家庭内受害者进行插入。这些结果对罪犯和刑事司法当局的干预有影响。
