Construction and validation of a surgical skills assessment tool for general surgery residency program

Objective: To develop and validate an instrument for measuring the acquisition of technical skills in conducting operations of increasing difficulty for use in General Surgery Residency (GSR) programs. Methods: we built a surgical skills assessment tool containing 11 operations in increasing levels of difficulty. For instrument validation we used the face validaity method. Through an electronic survey tool (Survey MonKey(r)) we sent a questionnaire to Full and Emeritus members of the Brazilian College of Surgeons - CBC - all bearers of the CBC Specialist Title. Results: Of the 307 questionnaires sent we received 100 responses. For the analysis of the data collected we used the Cronbach's alpha test. We observed that, in general, the overall alpha presented with values near or greater than 0.70, meaning good consistency to assess their points of interest. Conclusion: The evaluation instrument built was validated and can be used as a method of assessment of technical skill acquisition in the General Surgery Residency programs in Brazil.

研究目标：开发并验证一款测评工具，用于评估普外科住院医师（General Surgery Residency, GSR）培训项目中，操作人员完成难度逐级提升的手术操作的技能掌握情况。
研究方法：本研究构建了一套包含11项难度分级递增手术操作的外科技能测评工具。在工具效度验证环节，我们采用了表面效度法。通过电子调研平台SurveyMonkey®，我们向巴西外科医师学院（Brazilian College of Surgeons, CBC）的正式会员与荣誉会员——所有受访者均持有CBC专科医师资质——发放了调查问卷。
研究结果：本次共发放307份问卷，回收有效回复100份。针对采集到的研究数据，我们采用克朗巴哈α系数（Cronbach's alpha）检验法开展分析。结果显示，整体克朗巴哈α值接近或大于0.70，表明该测评工具对其所关注的测评维度具备良好的内部一致性。
研究结论：本研究构建的外科技能测评工具已通过效度验证，可作为巴西普外科住院医师培训项目中手术操作技能掌握情况的测评方法。
