Initial evaluation of a shoulder arthroscopy simulator: establishing construct validity.

Formal evaluation of surgical simulators is essential before their introduction into training programs. We report our assessment of the Mentice Corp Procedicus shoulder arthroscopy simulator. This study tests the hypothesis of construct validity that experienced surgeons will score better on the simulator than individuals with minimal to no experience with the technique.

Virtual reality applied to procedural testing: the next era.

Objective: To establish the construct validity of a virtual reality-based upper gastrointestinal endoscopy simulator as a tool for the skills training of residents.

Summary Background Data: Previous studies have demonstrated the relevance of virtual reality training as an adjunct to traditional operating room learning for residents. The use of specific task trainers, which have the ability to objectively analyze and track user performance, has been shown to demonstrate improvements in performance over time.

Evaluation of the educational effectiveness of a virtual reality intravenous insertion simulator.

Objective: To evaluate construct and content validity as well as learners' perceptions of CathSim, a virtual reality intravenous (IV) insertion simulator.

Methods: A prospective cohort study design was employed to determine construct validity, and a participant survey was used to ascertain content validity as well as user perceptions of CathSim. Forty-one attendings, residents, and medical students in emergency medicine and anesthesia attempted five simulated IV insertions on CathSim.
