Development of a new virtual reality test of cognition: Assessing the test-retest reliability, convergent and ecological validity of CONVIRT

Abstract

Background: Technological advances provide an opportunity to refine tools that assess central nervous system performance. This study aimed to assess the test-retest reliability and convergent and ecological validity of a newly developed, virtual-reality, concussion assessment tool, 'CONVIRT', which uses eye-tracking technology to assess visual processing speed, and manual reaction time (pushing a button on a riding crop) to assess attention and decision-making. CONVIRT was developed for horse jockeys, as of all sportspersons, they are most at risk of concussion. Methods: Participants (N = 165), were assessed with CONVIRT, which uses virtual reality to give the user the experience of riding a..
