Abstract
Study objective
To assess face and construct validity of a new virtual reality (VR) training simulator for hysteroscopic placement of tubal sterilization implants.
Design
Nonrandomized, controlled trial comparing responses and performance of novices and experts on the simulator.
Design classification
Canadian task force II-1.
Setting
Forty-six gynecologists were personally invited or recruited at the 33rd Conference of the French National College of Gynecologists and Obstetricians (CNGOF) from December 9 to 12, 2009, grouped as 20 experts and 26 novices. They all performed the defined sequence of virtual procedures on the simulator (case 1 for familiarization, case 4 for study assessment) and finally completed the study questionnaire.
Measurements and main results
Responses to realism, educational potential, and general opinion were excellent, proving face validity. Significant differences between novices and experts were assessed for 7 of the 15 metrics analyzed, proving construct validity.
Conclusions
We established face and construct validity for EssureSim™, an educational VR simulator for hysteroscopic tubal sterilization implant placement. The next steps are to investigate convergent and predictive validity to affirm the real capacity of transferring the skills learned on the training simulator to the patient in the operating room.
