摘要

Background

Visual vertigo (VV) is dizziness triggered by visually complex environments and is common in vestibular disorders such as Persistent Postural Perceptual Dizziness (PPPD). The Visual Vertigo Analogue Scale (VVAS) is a validated tool for assessing VV severity, but no Dutch version is currently available.

Objective

This study involved translating the original English version of the VVAS into Dutch, followed by adaptation and validation to ensure reliability and consistency with the source version.

Methods

The VVAS was translated using forward–backward translation. The final version was tested in 104 participants (PPPD patients and healthy controls). Internal consistency (Cronbach’s alpha), test–retest reliability (Intraclass Correlation Coefficient), and construct validity (factor analysis and regression modeling) were assessed.

Results

The Dutch VVAS showed high internal consistency (Cronbach’s alpha = 0.93), comparable to the original version. Test–retest reliability was adequate (ICC = 0.67). VVAS scores were significantly higher in PPPD patients compared to healthy controls (p < 0.001), controlling for age and gender.

Conclusion

The Dutch VVAS is a reliable and valid tool for assessing VV in Dutch-speaking populations, making it suitable for clinical and research applications.
