痴呆态度量表在社区护士中的信度效度研究

Adaptation and validation of Dementia Attitudes Scale to Chinese community nurses

目的:引进并汉化痴呆态度量表(Dementia Attitudes Scale,DAS),在社区护士中对其信度、效度进行检验。方法:对DAS进行翻译及文化调试,形成中文版DAS;在重庆主城9个行政区中随机抽取4个,按比例方便抽取213例社区护士进行调查,评价中文版DAS的信度和效度。结果:中文版DAS最终保留20个条目,各条目的内容效度指数(I-CVI)为0.80~1.00,平均内容效度指数(S-CVI/Ave)为0.98;探索性因子分析提取3个公因子,形成“痴呆知识”“负向社会舒适度”和“正向社会舒适度”三个维度,累计方差贡献率为48.026%;量表Cronbach’sα系数为0.787,各维度Cronbach’sα系数分别为0.854、0.704和0.752。结论:中文版DAS在社区护理人员中具有良好的信度、效度,可有效反映被测人群对痴呆患者的态度。

Objective:To translate the Dementia Attitudes Scale(DAS)into Chinese and evaluate its reliability and validity in community nurses.Methods:The Chinese version of DAS(DAS-C)was translated from the original English version and adjusted for cultural adaptation.The reliability and validity were tested in 213 community nurses who were proportionally selected from nine administrative divisions in Chongqing urban area.Results:The DAS-C contains 20 items.The item content validity index(I-CVI)ranged from 0.80 to 1.00,the average content validity index(S-CVI/Ave)was 0.98.Three common factors that explained 48.026%of variance were extracted,which were dementia knowledge,positive social comfort and negative social comfort.The Cronbach'sαcoefficient was 0.787,and the Cronbach'sαcoefficient for the three dimensions was 0.854,0.704 and 0.752,respectively.Conclusion:DAS-C shows good reliability and validity.It is a valid tool to assess the attitudes of community nurses towards patients with dementia.
