ABSTRACT
 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.

ÖZET
 Amaç: Bu çalışmanın amacı, Sanal Gerçeklik Rahatsızlığı Anketi'nin (SGRA) Türkçe versiyonunun güvenilirlik ve geçerliliğini araştırmaktır. Gereç ve Yöntemler: Bu çalışmaya 18-30 yaş arası 100 katılımcı (57 kadın, 43 erkek) dâhil edildi. Tüm katılımcılar 20 dk boyunca sanal gerçeklik (SG) deneyimi yaşadı. SGRA ve Graybiel Ölçeği puanları SG'den önce, SG'den sonra 1, 10, 20 ve 60. dk'larda olmak üzere 5 kez sorgulandı. İç tutarlılık için Cronbach alfa, doğrulayıcı faktör analizi için Kaiser-Meyer-Olkin (KMO) ve Bartlett testleri, eş zamanlı geçerliliği için korelasyon etkililiği uygulandı. Bulgular: Cronbach-α değerleri SGRA için SG sonrası 1 ve 10. dk iç tutarlılığının orta düzeyde olduğunu gösterdi (α=0,674, α=0,633). KMO (0,653) ve Bartlett testleri ise verilerin yeterli olduğunu gösterdi. SGRA ile Graybiel Ölçeği arasındaki korelasyonlar SG sonrası 1 ve 10. dk'larda çok iyiydi (r=0,786, r=0,657). Sonuç: Bu çalışma, SGRA'nın Türkçe versiyonunun SG ortamında hareket hastalığını değerlendirmek için geçerli ve güvenilir olduğunu göstermektedir. Hareket hastalığını objektif bir ölçüm aracı ile değerlendirmek, SG ile ilgili çalışmaların kalitesini artırabilir. Bu anketin, Türkçe versiyonunun literatüre dâhil edilmesi SG konusunda çalışma yapacak birçok araştırmacı için yol gösterici olabilir.
