Impostor phenomenon is a term used to describe feelings of intellectual and professional fraudulence. The Clance Impostor Phenomenon Scale and the Leary Impostorism Scale are two self-report measures used to determine whether an individual experiences impostor phenomenon. This study examined the psychometric properties of both measures in healthcare simulation educators.
The study sample comprised 148 educators, 114 (77%) females, 34 (23%) males, who completed an online version of each instrument. Exploratory factor analysis was used to examine the factor structure of the Clance Impostor Phenomenon Scale and the Leary Impostorism Scale.
Exploratory factor analysis revealed that for both instruments a one-factor solution best fit the data, suggesting all items in both measures fit onto a single theoretical construct. Both instruments demonstrated high internal reliability, with the Cronbach's alpha for the Clance Impostor Phenomenon Scale being α = .96 and the Leary Impostorism Scale α = .95.
This study suggests that impostor phenomenon as measured by the Clance Impostor Phenomenon Scale and the Leary Impostorism Scale is a unidimensional construct among healthcare simulation educators. With a growing interest in impostor phenomenon, the present findings will assist researchers to evaluate the phenomenon in healthcare settings.
冒名顶替现象是一个用来描述智力和职业欺诈感的术语。克莱恩冒名顶替现象量表和利里冒名顶替量表是两种用于确定个体是否经历冒名顶替现象的自我报告量表。本研究在医疗保健模拟教育者中检验了这两种量表的心理测量特性。
研究样本包括 148 名教育者，其中 114 名（77%）为女性，34 名（23%）为男性，他们完成了每种工具的在线版本。探索性因素分析用于检验克莱恩冒名顶替现象量表和利里冒名顶替量表的结构。
探索性因素分析表明，对于这两种工具，单因素解决方案最适合数据，表明两种量表中的所有项目都适合单一的理论结构。两种工具都表现出较高的内部可靠性，克莱恩冒名顶替现象量表的克朗巴赫α为α=0.96，利里冒名顶替量表的α=0.95。
本研究表明，医疗保健模拟教育者的克莱恩冒名顶替现象量表和利里冒名顶替量表所测量的冒名顶替现象是一个单一维度的结构。随着对冒名顶替现象的兴趣日益浓厚，本研究结果将有助于研究人员在医疗保健环境中评估这一现象。
