简要总结

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.

研究组 & 干预措施

Vestibular Patients

The target population of this study consists of individuals aged 18 years and older who can read and understand Turkish and experience dizziness triggered by visual or environmental stimuli. Written informed consent will be obtained from all participants. Sociodemographic and clinical characteristics, including age, sex, occupation, smoking and alcohol use, comorbidities, medical history, medications, daily activity level, onset and type of the condition, fall history, and sensitivity to heights, darkness, and crowded environments, will be recorded using a researcher-designed form. Based on the "item number × 10" rule, at least 190 participants will be included for the 19-item Situational Vertigo Questionnaire (SVQ). Participants will complete the SVQ, Dizziness Handicap Inventory (DHI), and Vertigo Symptom Scale (VSS), and rate satisfaction using a Visual Analog Scale. Test-retest reliability will be assessed in at least 20% of participants after 7-14 days.

结局指标

主要结局

Situational Vertigo Questionnaire (SVQ)

时间窗: Baseline and 7-14 days follow-up

The Situational Vertigo Questionnaire (SVQ) is a 19-item self-report scale designed to assess visual vertigo associated with increased visual dependence and insufficient vestibular compensation. Visual vertigo refers to dizziness triggered or worsened in visually complex or disorienting environments such as supermarkets, driving, or moving visual scenes. The condition is thought to arise from difficulties resolving conflicts between visual, vestibular, and proprioceptive inputs. The SVQ asks individuals to rate the severity of dizziness in situations involving visual motion or visual-vestibular conflict. Each item is scored from 0 (none) to 4 (severe), and participants may select "never experienced" if applicable. The total score is calculated based on the average item score, adjusted for items marked as not experienced, with higher scores indicating more severe symptoms.

次要结局

  • Dizziness Handicap Inventory (DHI)(Baseline and 7-14 days follow-up)
  • Vertigo Symptom Scale (VSS)(Baseline and 7-14 days follow-up)
