第二版范德堡头颈症状调查量表的汉化及信度、效度检验

Reliability and validity of localised Vanderbilt head and neck symptom survey(Version 2.0)

目的对第二版范德堡头颈症状调查量表(Vanderbilt head and neck symptom survey,Version 2.0,VHNSS 2.0)进行汉化,并对其信度、效度进行初步检验。方法采用Brislin翻译和回译法,经5位专家咨询,对VHNSS 2.0进行汉化和跨文化调适,形成中文版量表,将量表应用在450例头颈癌(head and neck cancer,HNC)放疗患者中进行调查,采用项目分析、内容效度、探索性因子分析、Cronbachα系数、折半信度、反应度对量表信度、效度进行检验。结果翻译后中文版VHNSS 2.0量表共有50个条目(13个维度),416例患者完成调查研究,其中量表中条目27(使用止疼药)与条目43(假牙)2个条目由于调查对象没有使用止疼药、假牙者,条目无计分,只有48个条目进入项目与信度、效度分析。相关系数结果显示,各条目与总分的相关系数,除条目42的相关系数值为0.242(删除该条目),其余各条目相关系数值在0.318~0.735,均有统计学意义(均P<0.05)。条目水平内容效度指数为0.800~1.000,量表水平内容效度指数为0.932;探索性因子分析共提取10个公因子,累计方差贡献率73.303%;量表的Cronbachα系数为0.958,折半信度为0.865。中文版VHNSS 2.0量表最后保留47个条目(10个维度)。结论汉化版VHNSS 2.0具有良好的信度、效度,可以用于中国HNC放疗患者的治疗相关症状发生情况和严重程度的评估。

Objective To localise the Vanderbilt head and neck symptom survey(Version 2.0)(VHNSS 2.0)in Chinese and verify its reliability and validity.Methods The VHNSS 2.0 was localised in Chinese by using Brislin translation and back translation method after consultation with 5 experts.The VHNSS 2.0 scale was applied in the investigation into 450 patients who underwent radiotherapy for head and neck cancers.Reliability and validity of the scale were tested by item analysis,content validity,exploratory factor analysis,Cronbachαcoefficient,split-half reliability and responsiveness.Results The Chinese version of the VHNSS 2.0 scale has a total of 50 items,and 416 patients completed the investigation and study.Among them,item 27(use of painkillers)and item 43(dentures)were included in the scale.Due to the presence of patients who did not use painkillers and dentures,the‘not applicable’option was selected,and the items did not score.Only 48 items entered the project and reliability and validity analysis.The correlation coefficient method showed that the correlation coefficient between each item and the total score was 0.242(delete the item),and the correlation coefficient of the remaining items was 0.318~0.735,all of which were statistically significant(all P<0.05).The item-level content validity index was 0.800~1.000,and the scale-level content validity index was 0.932.A total of 10 common factors were extracted by exploratory factor analysis,and the cumulative variance contribution rate was 73.303%.The Cronbachαcoefficient of the scale was 0.958,and the split-half reliability was 0.865.The Chinese version of the VHNSS 2.0 scale finally retained 47 items.Conclusions The Chinese version of VHNSS 2.0 has good reliability and validity.It can be applied in evaluation of the occurrence and severity of treatment-related symptoms in Chinese patients undergoing radiotherapy for head and neck cancers.
