Summary
The Chinese Vertigo Symptom Scale (VSS-C) is a reliable and valid tool for assessing vertigo symptoms in patients with cervical spondylosis of the vertebral artery type in China.
Area of Science:
- Neurology
- Rehabilitation Medicine
- Psychometrics
Background:
- Cervical spondylosis of the vertebral artery type (CSA) can cause vertigo.
- A validated scale is needed to assess vertigo symptoms in Chinese CSA patients.
Purpose of the Study:
- To develop and validate a Chinese version of the Vertigo Symptom Scale (VSS-C).
- To assess the reliability and validity of the VSS-C for Chinese CSA patients.
Main Methods:
- The VSS was translated into Chinese (VSS-C).
- VSS-C was administered to 52 CSA patients and 21 healthy controls.
- Reliability (Cronbach's alpha, ICC) and validity (correlation with SF-36, group comparison) were assessed.
Main Results:
- VSS-C demonstrated good internal consistency (Cronbach's alpha = 0.886) and excellent test-retest reliability (ICC = 0.970).
- VSS-C showed significant correlation with SF-36, indicating good concurrent validity.
- VSS-C effectively distinguished CSA patients from healthy controls and reflected treatment improvements.
Conclusions:
- The VSS-C is a comprehensible, reliable, and valid instrument.
- VSS-C is suitable for evaluating vertigo symptoms in Chinese patients with CSA.
