We have developed, as part of our resident applicant ranking process, a computerized weighted scoring system incorporating, among other variables, the interview score (IS). This study was undertaken to test the IS as a dependent variable when the applicant file is available during the interview. Over a 3-year period, each of two faculty members interviewed 133 candidates in a "blinded" fashion (file unavailable) or 290 candidates with an "open" file. The mean discrepancy between paired interviewers (1 to 10 scale) was 1.34 +/- 0.10 for the blinded group versus 0.93 +/- 0.06 for the open group (p less than 0.001). Individual and multiple regression analysis were used to test the IS as a dependent variable in the open group, with the blinded group as a control. In each instance (except clerkship grades), the IS correlated more closely with other parameters (p less than 0.05) in the open group. Correlation coefficients were 0.27 (blinded) and 0.64 (open) for weighted scores combining all parameters (p less than 0.001) and 0.39 (blinded) and 0.65 (open) for multiple linear regression analysis (p less than 0.001). We conclude that the IS is significantly influenced if other objective variables are at hand, thus deflating the actual weight of the interview. To accurately quantify the value of the interview, a correction factor must be applied, or, more appropriately, the interview must be conducted blindly.
作为住院医师申请人排名程序的一部分，我们开发了一种计算机化加权评分系统，该系统纳入了面试分数（IS）等变量。本研究旨在测试在面试期间可获取申请人档案时，将IS作为因变量的情况。在3年期间，两名教员分别以“盲法”（档案不可用）方式面试了133名候选人，或以“开放档案”方式面试了290名候选人。配对面试官之间（1至10分制）的平均差异，盲法组为1.34±0.10，开放组为0.93±0.06（p<0.001）。使用个体和多元回归分析来测试开放组中作为因变量的IS，以盲法组作为对照。在每种情况下（除实习成绩外），开放组中IS与其他参数的相关性更强（p<0.05）。对于综合所有参数的加权分数，相关系数分别为0.27（盲法）和0.64（开放）（p<0.001），对于多元线性回归分析，相关系数分别为0.39（盲法）和0.65（开放）（p<0.001）。我们得出结论，如果有其他客观变量，IS会受到显著影响，从而降低了面试的实际权重。为了准确量化面试的价值，必须应用校正因子，或者更合适的是，必须以盲法进行面试。
