中文版波士顿腕管量表的信效度研究

目的分析中文版波士顿腕管量表(Boston carpal tunnel questionnaire,BCTQ)的信效度。方法将英文版BCTQ经过翻译、回译和文化调适后,对195例腕管综合征患者进行问卷调查,评定该工具的信效度。结果中文版BCTQ共19个条目2个维度,量表的Cronbachα系数为0.90~0.947。各条目的内容效度(content validity index,CVI)为0.9~1.0,全部条目的平均CVI为0.95。因子分析按2个维度分别进行,第1个维度提取2个公因子解释总变异的66.7%,第2个维度提取1个公因子解释总变异的73.25%。结论中文版BCTQ是一份具有较好信度和效度的评定工具,可用于我国腕管综合征患者的病情评估。

Study of the Reliability and Validity of Chinese Version of the Boston Carpal Tunnel Questionnaire

Objective To assess the reliability and validity of the Chinese version of the Boston Carpal Tunnel Questionnaire(BCTQ).Methods The English version of the Boston Carpal Tunnel Questionnaire (BCTQ)was translated,retroversion and was culture-adapted.Totally 195 cases were evaluated by questionnaire,and the reliability and validity were evaluated.Results The Chinese version of BCTQ was consisted of 19 items and 2 dimensions.The Cronbach’sαwas ranged from 0.90 to 0.947.The content validity index(CVI)was 0.9-1.0.The average CVI of all dimensions was 0.95.The factor analysis was conducted by two dimensions;the first dimension extracted 2 common factors which explained the 66.7%of total variance.The second dimension was extracted 1 common factor,which explained 73.25% of total variance.Conclusions The Chinese version of BCTQ has good reliability and validity,which can be applied in the disease evaluation of patients with carpal tunnel syndrome.
