The phenomenon of first impression is well researched in social psychology, but less so in the study of OSCEs and the multiple mini interview (MMI). To explore its bearing on the MMI method we included a rating of first impression in the MMI for student selection executed 2012 at the University Medical Center Hamburg-Eppendorf, Germany (196 applicants, 26 pairs of raters) and analyzed how it was related to MMI performance ratings made by (a) the same rater, and (b) a different rater. First impression was assessed immediately after an applicant entered the test room. Each MMI-task took 5 min and was rated subsequently. Internal consistency was α = .71 for first impression and α = .69 for MMI performance. First impression and MMI performance correlated by r = .49. Both measures weakly predicted performance in two OSCEs for communication skills, assessed 18 months later. MMI performance did not increment prediction above the contribution of first impression and vice versa. Prediction was independent of whether or not the rater who rated first impression also rated MMI performance. The correlation between first impression and MMI-performance is in line with the results of corresponding social psychological studies, showing that judgements based on minimal information moderately predict behavioral measures. It is also in accordance with the notion that raters often blend their specific assessment task outlined in MMI-instructions with the self-imposed question of whether a candidate would fit the role of a medical doctor.
第一印象现象在社会心理学中得到了广泛研究，但在 OSCE 和多项迷你面试（MMI）研究中则研究较少。为了探讨其对 MMI 方法的影响，我们在德国汉堡-埃彭多夫大学医学中心（University Medical Center Hamburg-Eppendorf）执行的 2012 年学生选拔 MMI 中包含了第一印象的评分（196 名申请者，26 对评分者），并分析了它与（a）同一评分者和（b）不同评分者做出的 MMI 表现评分之间的关系。第一印象是在申请人进入测试室后立即进行评估的。每个 MMI 任务需要 5 分钟，随后进行评分。第一印象的内部一致性为α=0.71，MMI 表现的内部一致性为α=0.69。第一印象和 MMI 表现之间的相关系数为 r=0.49。这两个指标都微弱地预测了 18 个月后进行的两项沟通技能 OSCE 的表现。MMI 表现并不能增加第一印象的贡献，反之亦然。预测与评分者是否评估第一印象和 MMI 表现无关。第一印象与 MMI 表现之间的相关性与相应的社会心理学研究结果一致，表明基于最小信息量的判断适度预测行为测量。这也符合评分者通常将他们在 MMI 指令中概述的特定评估任务与他们自行提出的候选人是否适合医生角色的问题结合起来的观点。
