目的
2
使用经尿道前列腺电切术(transurethral resection of the prostate,TURP)关键技术评价量表对初学者实施经尿道前列腺电切术的行为表现进行打分,旨在为该量表所得成绩的诠释积累效度证据。
方法
2
收集2023年1月至2024年3月期间,在上海交通大学医学院附属瑞金医院医学模拟中心参加经尿道前列腺电切术模拟培训的学员在培训前后实践技能模拟考核的成绩,各获取90份样本。本研究采用梅西克(Messick)效度框架,收集基于内容、反应过程、内部结构和其他变量的关系、测试后果5个方面的效度证据。
结果
2
本研究量表的内容效度指数为0.952。评分者间一致性采用Spearman相关系数来衡量,培训前后的总分Spearman相关系数分别为0.993和0.970。量表总分的Cronbach’s
α
系数在培训前后分别为0.987和0.947。验证性因子分析结果显示:

结论
2
本研究为经尿道前列腺电切术实践技能模拟考核积累了效度证据。经尿道前列腺电切术关键技术评价量表是适合用于评价初学者经尿道前列腺电切术技能的工具。
Objective
2
To score the behavioral performance of novices in transurethral resection of the prostate (TURP) using a TURP key skill assessment scale
and to accumulate validity evidence for the interpretation of scores derived from this scale.
Methods
2
Simulation-based assessment scores of practical skills were collected from 90 trainees
who participated in a simulation-based training on TURP at the Medical Simulation Center of Ruijin Hospital
Shanghai Jiao Tong University School of Medicine from January 2023 to March 2024
before and after training. Messick's framework of validity was used to collect validity evidence for test content
response process
internal structure
relations to other variables
and consequences.
Results
2
The content validity index of the scale was 0.952. The inter-rater consistency was measured using Spearman correlation coefficients
which were 0.993 and 0.970 for the total scores before and after training
respectively. The Cronbach's
α
coefficients for the total scale scores were 0.987 and 0.947 before and after training
respectively. The confirmatory factor analysis showed
χ

df
of 1.686
comparative fit index of 0.953
Tucker-Lewis index of 0.939
root mean square error of approximation of 0.087
and standardized root mean square residual of 0.036
indicating an acceptable model fit.
Conclusions
2
This study presents validity evidence for simulation-based assessment for TURP practical skills. The TURP key skill assessment scale is a suitable tool for evaluating the TURP skills of novice learners.
