The contrast validity of the Advanced Dundee Endoscopic Psychomotor Tester (ADEPT) was determined by comparing the performance of "master surgeons" with that of surgical trainees (also called junior surgeons) on the system.
Twenty master surgeons and 20 junior surgeons were tested on the ADEPT system. The master surgeons, all of consultant grade, were recruited as established experts of national or international standing in laparoscopic surgery. The junior surgeons were participants of essential laparoscopic courses at the start of their higher surgical training. The ADEPT end points used in the study were instrument error, execution time, and task completion. An analysis of variance was used for the data analysis, with statistical significance set at.05.
Master surgeons incurred a significantly lower instrument error rate than surgical trainees (P =.007), with no significant difference in execution time and the task completion score (P =.42 and P =.40, respectively).
The ADEPT system has contrast validity because master surgeons completed the tasks more accurately without sacrificing execution time.
通过比较“主刀医生”与外科实习生（也称为初级外科医生）在高级邓迪内镜心理运动测试仪（ADEPT）系统上的表现，来确定该系统的对比效度。
20名主刀医生和20名初级外科医生在ADEPT系统上接受测试。主刀医生均为顾问级别，是在腹腔镜手术方面具有国家或国际声誉的知名专家。初级外科医生是在其高级外科培训开始时参加基础腹腔镜课程的学员。该研究中使用的ADEPT终点指标为器械误差、执行时间和任务完成情况。采用方差分析进行数据分析，设定统计学显著性水平为0.05。
主刀医生的器械误差率显著低于外科实习生（P = 0.007），执行时间和任务完成得分无显著差异（分别为P = 0.42和P = 0.40）。
ADEPT系统具有对比效度，因为主刀医生在不牺牲执行时间的情况下更准确地完成了任务。
