Abstract:
Objective: To develop a Chinese version of Vertigo Symptom Scale ( VSS-C) and to examine its reliability and validity .Methods:The VSS was translated into Chinese and developed a Chinese version VSS ( VSS-C ) with the consent of the author .The VSS-C scale was tested in 52 subjects with cervical spondylosis of vertebral artery type ( CSA group ) and 21healthy subjects ( control group ) .In CSA group VSS-C scale and SF-36 scale investigation was performed for 2 times with 1 week interval , after receiving 1-week orthopedic rehabilitation the patients were evaluated with the VSS -C and SF-36 scale;while subjects in control group received the investigation twice in two weeks.The reliability of the scale was evaluated with Cronbach's alpha method and the correlation between SF-36 scale and the VSS-C were also evaluated for the validity . Results:The internal consistency of VSS-C was good with Cronbach's alpha of 0.886 . Test-retest reliability was also very good with an intraclass correlation coefficient ( ICC) between two time points , being 0.970 for VSS-C,0.965 for VSS-AA and 0.992 for the VSS-VER.Regarding concurrent validity ,significant low correlation was found between the VSS-AA and VSS-VER ( r=0.379 ,P<0.05 ) .Significant expected correlation was detected between the VSS-C and SF-36 ( r>0.5 ,P<0.05 ) .The independent-samples t test results ( t=6.261 ,P<0.01 ) of the CSA group and the control group showed that the VSS-C was able to distinguish healthy people from CSA patients . The paired-samples t test results ( t =5.513 , P <0.01 ) showed that VSS-C reflected the improvement of patients after treatment of Chinese massage manipulation .Conclusion:The Chinese version of VSS has a high comprehensibility , internal consistency and validity, and it can be a useful instrument for evaluation of patients with cervical spondylosis of vertebral artery type in China .
