Validation of a German Version of the Collision Anxiety Questionnaire

The main quality of virtual reality (VR) is its high immersive potential. However, the resulting inability to perceive the real world surroundings can distract users from the application due to the fear of colliding with obstacles or other people. The Collision Anxiety Questionnaire (CAQ) by Ring et al. measures this fear of colliding and consists of ten items in three subscales: general collision anxiety, orientation, and interpersonal collision anxiety. In this paper, we present a validated German version of the CAQ, which showed a good model fit, including good reliability and internal and discriminant validity. By validating the questionnaire, we offer researchers a tool to further explore and evaluate the concept of collision anxiety, helping to uncover previously under-explored aspects of the user experience.
