The United States Medical Licensing Examination (USMLE) Step 1 was the most cited factor in granting medical student applicants' residency interviews in a 2016 NRMP survey. Medical students utilize numerous commercial resources to achieve the highest score possible. This study sought to examine preparatory resources and their association with USMLE Step 1 performance.
In 2016 and 2017, 170 medical students from a public, Midwestern medical school completed a voluntary survey after completing USMLE Step 1. The survey asked about study aids, anticipated performance, test preparation time, and practice exam performance. Actual scores and academic performance (overall percent for years 1 and 2 of medical school) were matched to survey responses. Data was analyzed using descriptive and inferential statistical analyses.
USMLE Step 1 performance was associated with academic performance ( = 0.719, < 0.01). Post hoc tests indicated a positive difference with the UWorld Qbank and exam performance ( = 10.29, < 0.05). Amount of days dedicated to test preparation was negatively correlated with performance in the 2017 student cohort ( = - 0.304, < 0.01). The use of other commercially available products and the number of practice tests completed were not correlated with performance.
Cumulative pre-clinical grades had the strongest association with performance on the USMLE Step 1. Completing at least once was positively related with Step 1 scores. However, the use of other study aids, completing multiple practice exams, and delaying exam dates were not statistically significant. This study indicates performance in the pre-clinical curriculum and increased usage of UWorld are strongly associated with USMLE Step 1 performance.
在美国国家住院医师匹配项目（NRMP）2016年的一项调查中，美国医师执照考试（USMLE）第一步是决定医学生申请者能否获得住院医师面试资格时被引用最多的因素。医学生利用大量商业资源以取得尽可能高的分数。本研究旨在调查备考资源及其与USMLE第一步考试成绩的关联。
2016年和2017年，来自一所位于美国中西部的公立医学院的170名医学生在完成USMLE第一步考试后完成了一项自愿调查。该调查询问了学习辅助工具、预期成绩、备考时间以及模拟考试成绩。实际分数和学业成绩（医学院第一年和第二年的总成绩百分比）与调查回复进行了匹配。使用描述性和推断性统计分析对数据进行了分析。
USMLE第一步考试成绩与学业成绩相关（r = 0.719，P < 0.01）。事后检验表明，使用优思网校题库（UWorld Qbank）与考试成绩存在正相关（r = 10.29，P < 0.05）。2017年学生群体中，用于备考的天数与成绩呈负相关（r = -0.304，P < 0.01）。使用其他商业产品以及完成模拟考试的次数与成绩无关。
临床前累积成绩与USMLE第一步考试成绩的关联最为紧密。至少完成一次优思网校题库与第一步考试成绩呈正相关。然而，使用其他学习辅助工具、完成多次模拟考试以及推迟考试日期在统计学上并无显著意义。本研究表明，临床前课程的成绩以及更多地使用优思网校题库与USMLE第一步考试成绩密切相关。
