Face validity, construct validity and training benefits of a virtual reality turp simulator

Construct validity and expert benchmarking of the haptic virtual reality dental simulator.

The aim of this study was to demonstrate construct validation of the haptic virtual reality (VR) dental simulator and to define expert benchmarking criteria for skills assessment. Thirty-four self-selected participants (fourteen novices, fourteen intermediates, and six experts in endodontics) at one dental school performed ten repetitions of three mode tasks of endodontic cavity preparation: ea...

Face and content validity of a virtual-reality simulator for myringotomy with tube placement

BACKGROUND Myringotomy with tube insertion can be challenging for junior Otolaryngology residents as it is one of the first microscopic procedures they encounter. The Western myringotomy simulator was developed to allow trainees to practice microscope positioning, myringotomy, and tube placement. This virtual-reality simulator is viewed in stereoscopic 3D, and a haptic device is used to manipul...

Face, content and construct validity of the University of Washington virtual reality transurethral prostate resection trainer.

PURPOSE We examined the face, content and construct validity of version 1.0 of the University of Washington transurethral prostate resection (TURP) trainer. MATERIALS AND METHODS Version 1.0 of a virtual reality based simulator for transurethral skills was developed at our laboratory by integrating TURP hardware with our virtual 3-dimensional anatomy, irrigation control, cutting, bleeding and...

Addendum: Assessment of the Laparoscopic Training Validity of a Virtual Reality Simulator (LAP Mentor™)

Validity of Measurement Content Validity Face Validity Concurrent Validity Predictive Validity Construct Validity Thinking Critically About Everyday Information

An essential component of an operational definition is measurement. A simple and accurate definition of measurement is the assignment of numbers to a variable in which we are interested. These numbers will provide the raw material for our statistical analysis. Measurement is so common and taken for granted that we seldom ask why we measure things or worry about the different forms that measurem...
