Background and Objectives: Virtual reality (VR) applications change the perception of reality, resulting in a feeling of being in a natural environment. The occurrence of cybersickness (CS) when using VR applications is a well-documented side effect, and the Simulator Sickness Questionnaire (SSQ) has been used to assess CS. Considering the speed of VR technology development, CS will likely become a frequently researched and discussed topics in the near future. Therefore, the aim of this study was to conduct a Turkish validity and reliability study and introduce the SSQ to Turkish medical literature. Materials and Methods: A total of 160 healthy individuals (80 females and 80 males) aged >18 years (28.4±7.2 years) were included in our study. The SSQ was provided to the participants through Google Forms before and after the VR provocation experience and within the scope of the test and retest protocol. Results: The reliability and internal consistency of the questionnaire were observed at a high level (Cronbach’s alpha=0.854, Spearman-Brown coefficient r=0.871). Factor analysis was performed and the questionnaire was divided into three subfactors, consistent with the original questionnaire. In the responses obtained from the participants before and after VR provocation, statistically significant differences were observed in 13 of the 16 items in the questionnaire that are related to VR provocation (p<0.05). Statistically, the differences in fatigue, dizziness, and vertigo were greater in females than in males (p<0.05). Conclusions The Turkish version of the SSQ is an effective tool for measuring the side effects in VR environments. The inclusion of the SSQ in the Turkish literature enables the inclusion of non-English-speaking participants in research, especially for disciplines that consider peripheral and central vestibular disorders.
