There is an increasing demand for structured objective ex vivo training and assessment of laparoscopic psychomotor skills prior to implementation of these skills in practice. The aim of this study was to establish the internal validity of the TrEndo, a motion-tracking device, for implementation on a laparoscopic box trainer.
Face validity and content validity were addressed through a structured questionnaire. To assess construct validity, participants were divided into an expert group and a novice group and performed two basic laparoscopic tasks. The TrEndo recorded five motion analysis parameters (MAPs) and time.
Participants demonstrated a high regard for face and content validity. All recorded MAPs differed significantly between experts and novices after performing a square knot. Overall, the TrEndo correctly assigned group membership in 84.7 and 95.7% of cases based on two laparoscopic tasks.
Face, content, and construct validities of the TrEndo were established. The TrEndo holds real potential as a (home) training device.
在实践中实施这些技能之前，对腹腔镜心理运动技能进行结构化的客观离体培训和评估的需求不断增加。本研究的目的是确定 TrEndo（一种运动跟踪设备）在腹腔镜箱式训练器上应用的内部有效性。
通过结构化问卷来解决表面有效性和内容有效性。为了评估结构有效性，参与者被分为专家组和新手组，并进行了两项基本的腹腔镜任务。TrEndo 记录了五个运动分析参数（MAPs）和时间。
参与者对表面和内容有效性评价很高。在完成方结后，所有记录的 MAPs 在专家和新手之间均有显著差异。总体而言，基于两项腹腔镜任务，TrEndo 正确地将 84.7%和 95.7%的案例分配到了相应的组中。
确立了 TrEndo 的表面、内容和结构有效性。TrEndo 作为（家庭）培训设备具有真正的潜力。
