Objective: This study aimed to investigate reliability and validity of the Turkish version of Virtual Reality Sickness Questionnaire (VRSQ). Material and Methods: Hundred participants, between the ages of 18-30, were included in this study (57 female, 43 male). All participants experienced virtual reality (VR) for 20 minutes. VRSQ and Graybiel Scale scores were asked five times; before VR, at 1st, 10th, 20th and 60th mins-after VR. Cronbach's alpha for the internal consistency, Kaiser-Meyer-Olkin (KMO) and Bartlet't tests for confirmatory analysis, the correlation efficient for concurrent validity were performed. Results: The Cronbach-α values indicated moderate internal consistency for VRSQ at the 1st and 10th mins-after VR (α=0.674, α=0.633). KMO (0.653) and Bartlett tests showed that data is adequate. The correlations between VRSQ and Graybiel Scale were very good at the 1st and 10th mins-after VR (r=0.786, r=0.657). Conclusion: This study presents the Turkish version of VRSQ is reliable and valid for evaluating motion sickness in the VR environment. To assess motion sickness with an objective measurement tool can improve the quality of studies about VR. The inclusion of the Turkish version of this questionnaire to the literature can be a guide for many researchers who will investigate VR.
