Subjects (n = 246) were asked to identify the trait(s) measured by Rotter's Interpersonal Trust Scale with and without filler items, either by responding freely or by circling traits listed on a sheet. Half the subjects were informed prior to filling out the questionnaire that their task was to identify the traits being measured by the questionnaire; the remaining half of the subjects were informed of their task after they completed the questionnaire. Very few subjects were able to identify correctly the trait being measured by Rotter's scale regardless of the experimental condition. Most subjects named multiple traits. It was concluded that the use of filler items per se was not the key factor in disguising the true purpose of Rotter's test; rather item wording may have produced multiple interpretations.
研究对象（n = 246）被要求在有或没有填充项目的情况下，通过自由作答或圈选问卷上列出的特质，来识别罗特人际信任量表所测量的特质。一半的研究对象在填写问卷前被告知其任务是识别问卷所测量的特质；其余一半的研究对象在完成问卷后才被告知其任务。无论实验条件如何，很少有研究对象能够正确识别罗特量表所测量的特质。大多数研究对象列出了多个特质。研究得出结论，填充项目本身并非掩盖罗特测试真正目的的关键因素；相反，项目措辞可能产生了多种解读。
