False allegations constitute a problem since they may cause harm. To study the difference between true and false allegations we used a quasi-experimental approach. In the control condition likely true allegations were retrieved from criminal files. The victims, all female, were between the ages of 17 and 53 (M = 28.0, SD = 10.6). In the experimental condition women were invited to file a false allegation. Participants, all female, in the experimental conditions were between the ages of 18 and 52 (M = 28.0, SD = 10.6). We constructed a list of 187 variables based on our theory of fabricated rape. All items in the list were coded dichotomously. All variables that were coded as ‘present’ within cases were summed to obtain a total score; an independent t-test was used. The results of the control condition (N = 30) were compared with the experimental condition (N = 35) by use of chi-square tests. A Holm-Bonferoni method with Sidak correction was used to correct for the increased family-wise error rate. The independent t-test showed a significant difference between the mean number of present-coding of likely true allegations, (M = 59.13, SD = 11.00) and of false allegations (M = 35.74, SD = 9.33), t(63) = 9.28, p < .0001, d = 2.34. Thus, significantly more variables were coded ‘present’ in likely true allegations. Fabricated stories of rape lack pseudo-intimate behavior and a wide variety of sexual acts. Also, in almost all fabricated stories of rape the attack was completed in less than 15 minutes while in likely true allegations the attack sometimes took over 60 minutes before it was completed. In conclusion, true and false allegations diverge from each other in essentials of the story told by the complainant. The differences could be used to predict the true nature of a rape allegation.

提交虚假的恶习报告：将真实与虚假的强奸指控区分开

错误的指控构成问题，因为它们可能造成伤害。为了研究真假指控之间的区别，我们使用了一种准实验方法。在控制条件下，可能从犯罪档案中检索到了真实的指控。受害者均为女性，年龄在17至53岁之间（M = 28.0，SD = 10.6）。在实验条件下，邀请女性提出虚假指控。在实验条件下，所有女性参与者均为18至52岁（M = 28.0，SD = 10.6）。基于我们的强奸理论，我们构建了187个变量的列表。列表中的所有项目均一分为二。将案例中被编码为“存在”的所有变量相加以获得总分；使用独立的t检验。通过卡方检验将对照条件（N = 30）的结果与实验条件（N = 35）进行比较。使用具有Sidak校正的Holm-Bonferoni方法校正增加的家庭错误率。独立的t检验显示，可能的真实指控（M = 59.13，SD = 11.00）和错误指控（M = 35.74，SD = 9.33），t（63）= 9.28，p ＜.0001，d ＝ 2.34。因此，在可能的真实指控中，更多的变量被编码为“存在”。虚构的强奸故事缺乏伪亲密行为和各种各样的性行为。同样，在几乎所有捏造的强奸事件中，攻击都是在不到15分钟的时间内完成的，而在真正的指控中，攻击有时要花60分钟才能完成。结论，真实和虚假指控在申诉人讲述的故事要点上彼此不同。这些差异可以用来预测强奸指控的真实性质。
