许多研究人员发现很难招募个体，特别是少数民族的个体参与研究。对研究和研究人员的不信任可能成为参与的障碍。本研究的目的是建立一个评估医学研究人员信任的量表。方法：通过对25名非裔美国成年人的多重认知预测试和对南卡罗来纳州512名成年人的随机数字拨号电话调查，我们开发了一个多项目量表。采用正交旋转法、斜旋转法和Cronbach’s alpha法对医学研究者信任量表的心理测量特征进行因子分析。我们评估建构效度以及未来参与医学研究计画的行为意向。结果探索性因子分析的正交旋转和斜旋转结果相似，在最终纳入量表的12个项目中存在2个不同的因素。整个量表的Cronbach’s a为0.84，而第一因子被试欺骗的Cronbach’s a为0.78，第二因子研究者诚实的Cronbach’s a为0.75。白人受访者（28.7 +/- 5.6）比非裔美国人受访者（24.1 +/- 6.9）更信任
PURPOSE Many researchers find it difficult to recruit individuals, particularly minorities, for participation in studies. Mistrust of research and researchers may act as a barrier to participation. The purpose of this study was to develop a scale for assessing trust in medical researchers.METHODS We developed a multi-item scale by means of multiple cognitive pretests with 25 African American adults and a random-digit-dialing telephone survey of 512 adults in South Carolina. Psychometric characteristics of the Trust in Medical Researchers Scale was assessed by factor analysis using both orthogonal and oblique rotations and Cronbach's alpha. We assessed construct validity as well as a behavioral intention for future participation in a medical research project.RESULTS The results of the orthogonal and oblique rotations in the exploratory factor analysis were similar and suggested 2 distinct factors in the final 12 items included in the scale. Cronbach's a for the entire scale was 0.84, whereas it was 0.78 for the first factor of Participant Deception and 0.75 for the second factor of Researcher Honesty. White respondents (28.7 +/- 5.6) had greater trust than African American respondents (24.1 +/- 6.9) (P
