This study was planned to examine the validity and reliability of the Turkish version of the Situational Vertigo Questionnaire (SVQ), which is used to evaluate dizziness symptoms frequently seen in vestibular pathologies and triggered by visual or environmental stimuli. The research is designed as a methodological scale adaptation and psychometric evaluation study. The study plans to include individuals aged 18 and over who can read and understand Turkish and have complaints of situational dizziness. The Turkish adaptation process of the SVQ will be carried out using the back-and-forth translation method; a pilot application will be conducted after ensuring linguistic and cultural equivalence. For the psychometric evaluation, the sample size is planned to be at least 10 times the number of items, and participants will be asked to complete the SVQ, as well as the Dizziness Handicap Inventory (DHI), Vertigo Symptom Scale (VSS), and Visual Analog Scale (VAS). To evaluate test-retest reliability, a subgroup of participants will be re-administered the SVQ after 7 days. No invasive procedures will be performed on participants during the research; only survey forms will be used. Written informed consent will be obtained from all participants, and data will be coded and analyzed in accordance with confidentiality principles. It is expected that the findings of this study will contribute to the literature by establishing a valid and reliable measurement tool in Turkish for the evaluation of situational dizziness symptoms and will support clinical evaluation processes.
