This study examined the concurrent validity of the Objective Structured Assessment of Technical Skill (OSATS), a new test of technical skill for general surgery residents.
Twelve residents (six in their senior, or fifth, year and six in their junior, or third, year) at the University of Toronto in 1994-95 were ranked within level of training according to their OSATS marks and by surgical faculty. Correspondence between OSATS and faculty rankings was assessed using Spearman rank-order correlation coefficients.
The correlations between test scores and faculty rankings were generally high for the senior residents but low for the junior residents.
Scores on the OSATS accurately reflect the independent opinions of faculty regarding the technical skills of senior residents, suggesting that it is a valid measure of technical skill for these individuals. The scores did not, however, reproduce faculty rankings of the junior residents. Whether this was a failing of the OSATS or the faculty rankings requires further study.
本研究检验了客观结构化技术技能评估（OSATS）的同时效度，这是一种针对普通外科住院医师的新技术技能测试。
1994 - 1995年，多伦多大学的12名住院医师（6名高年级即五年级，6名低年级即三年级）根据其OSATS分数和外科教员的评价，在培训水平内进行排名。使用斯皮尔曼等级相关系数评估OSATS与教员排名之间的一致性。
高年级住院医师的测试分数与教员排名之间的相关性普遍较高，而低年级住院医师的相关性较低。
OSATS分数准确反映了教员对高年级住院医师技术技能的独立评价，表明它是这些人技术技能的有效衡量标准。然而，这些分数并未重现教员对低年级住院医师的排名。这是OSATS的缺陷还是教员排名的问题，需要进一步研究。
