Using a randomized controlled trial, we investigated changes in both sexual harassment (SH) perpetration and victimization of 2104 middle school students in New York City who received divergent saturation and dosage levels of Shifting Boundaries, an SH prevention program, which was represented by the length of the program. We assessed the saturation effect of the program by comparing the outcomes across respondents from 26 schools in which there were varying percentages of students enrolled in the program. The data suggested that, overall, the program was effective in reducing sexual harassment victimization but achieved a null effect against respondents' SH perpetration and that neither the length nor the school-saturation level of the program exerted a significant effect on SH perpetration. Although the data indicated a significant difference in SH victimization between the treatment and control group, when comparing subgroups who received treatment with divergent saturation and dosage levels, no statistically significant difference was identified. Our results suggested that the program effect was not contingent on the portion of students in a school who enrolled in the program, nor was it contingent on the dosage.
我们采用随机对照试验，调查了纽约市2104名中学生在性骚扰（SH）行为及受侵害情况方面的变化。这些学生接受了不同程度的“转变界限”（Shifting Boundaries）项目干预，该项目为一项预防性骚扰计划，以项目时长来体现其饱和度和剂量水平差异。我们通过比较26所学校中参与该项目学生比例各异的受访者的结果，评估了该项目的饱和度效应。数据表明，总体而言，该项目在减少性骚扰受侵害方面是有效的，但对受访者的性骚扰行为没有效果，且项目时长和学校饱和度水平对性骚扰行为均未产生显著影响。尽管数据显示治疗组和对照组在性骚扰受侵害方面存在显著差异，但在比较接受不同饱和度和剂量水平治疗的亚组时，未发现统计学上的显著差异。我们的结果表明，该项目的效果既不取决于学校中参与项目的学生比例，也不取决于剂量。
