Validation process for new endoscopy teaching tools

With the development of any new technology or educational curriculum, validation of its effectiveness is a critical but often overlooked step. When validation is performed, it is often done in a very superficial manner and all too often the results are wrongly extrapolated to draw conclusions on findings independent of the aspects validated. In this review we describe the process required to establish rigorous and more accurate validation evidence of simulation tools and teaching curriculum. These steps will be demonstrated through the review of our experiences with computerized colonoscopy simulators over the past decade. As educators and researchers, placing a focus on developing strong validity evidence for the use of new educational tools is something we owe not only to our trainees and institutions but also to our patients. Educators must be diligent in researching new educational devices or curriculum to ensure they truly enhance current training and improve patient outcomes.
