嗓音疲劳指数量表中文版信度和效度评价

Reliability and Validity of Chinese Version of Voice Fatigue Index

目的对中文版嗓音疲劳指数(voice fatigue index,VFI)量表进行信度和效度评价。方法对VFI量表进行系统翻译,采用跨文化翻译法形成中文版VFI量表,首先选取20例嗓音疾病患者及20例健康对照组进行两次VFI量表评估,然后选取哈尔滨第四医院就诊的106例嗓音障碍患者为观察组及114例健康患者为对照组共220例进行中文版VFI量表评估,对其进行信效度评价。结果中文版VFI量表3个分量表cronbachα系数为0.925~0.933,折半系数为0.898~0.935;相关性分析r为0.920~0.970(P<0.01);因素分析特征根大于“1”的公因子3个,累计贡献率分别为53.743%、67.233%、72.923%,各条目负荷大于0.4;嗓音疾病患者即观察组与健康对照组比较3部分评分有显著差异(P=0.000)。结论经验证,中文版VFI量表信度和效度良好,可作为评估嗓音疲劳的有效工具。

Objective To evaluate the reliability and validity of the Chinese version of Voice Fatigue Index(VFI).Methods The VFI scale was translated and the Chinese version of the VFI scale was performed by cross-cultural translation method.First,20 patients with voice disorders and 20 healthy controls were selected for scale evaluation twice.Then,106 patients with voice disorders in the Fourth Hospital of Harbin were selected as the observation group and 114 healthy people as the control group,a total of 220 people were evaluated by the Chinese version of VFI scale,and its reliability and validity were evaluated.Results The Cronbachαcoefficients of the three subscales of the Chinese VFI scale ranged from 0.925 to 0.933,and the half-coefficients ranged from 0.898 to 0.935.Correlation analysis r was 0.920-0.970(P<0.01).There were three common factors whose characteristic roots were greater than 1,and the cumulative contribution rates were 53.743%,67.233%and 72.923%,respectively,and each item load was greater than 0.4.There was a statistically significant difference between the observation group and the healthy control group(P=0.000).Conclusion The Chinese version of VFI scale has been proved to be reliable and valid,and can be used as an effective tool for evaluating voice fatigue.
