Computer-assessed performance of psychomotor skills in endoscopic otolaryngology surgery: construct validity of the Dundee Endoscopic Psychomotor Otolaryngology Surgery Trainer (DEPOST)

Background This study was undertaken to introduce and establish the value of the Dundee Endoscopic Psychomotor Otolaryngology Surgery Trainer (DEPOST) as a customisable, objective real-time scoring system for trainee assessment. The construct validity of the system was assessed by comparing the performance of experienced otolaryngologists with that of otolaryngology trainees, junior doctors and medical students.
