世界卫生组织老年整合照护筛查工具的汉化及信效度检验

Reliability and validity of the Chinese version of WHO Integrated Care for Older People screening tool

目的汉化英文版世界卫生组织(WHO)老年整合照护(ICOPE)筛查工具,并检验其信效度。方法采用Brislin翻译法翻译英文版WHO ICOPE筛查工具,通过专家小组讨论和预调查来进行调适,形成中文版WHO ICOPE筛查工具。采用方便抽样法选取150名≥60岁老年患者,采用一般情况调查问卷和中文版WHO ICOPE筛查工具进行面对面调查;采用极端组比较法和Spearman等级相关分析法进行项目分析;采用Cronbach′sα系数和分半信度Spearman-Brown系数进行信度分析;采用探索性因子分析进行结构效度分析。结果中文版WHO ICOPE筛查工具包括6个条目,8个问题。项目区分度极端组比较法显示,高分组(42例)和低分组(60例)各条目得分差异有统计学意义(P均<0.05);Spearman等级相关分析结果显示,各条目得分与总分均呈正相关(均P<0.001)。信度检验结果显示,Cronbach′sα系数为0.612,删除任意一个条目后的Cronbach′sα系数范围在0.514~0.579,提示无需删除的条目;分半信度的结果显示,Spearman-Brown分半系数为0.683。探索性因子分析提取到了初始特征值>1的公因子共2个,其方差贡献率均>20%,累积方差贡献率为53.85%。结论中文版WHO ICOPE筛查工具的信度和效度良好,可用于老年人内在能力下降的筛查。

Objective To translate the English version of World Health Organization(WHO)Integrated Care for Older People(ICOPE)screening tool into Chinese,and test the reliability and validity of the Chinese version of WHO ICOPE screening tool.Methods The Chinese version of WHO ICOPE screening tool was translated using the Brislin translation method,and then adapted through expert group discussion and pre-surveys.A total of 150 patients≥60 years old were included,face-to-face surveys were conducted using a general situation questionnaire and the Chinese version of WHO ICOPE screening tool.Item analyses were conducted using extreme group comparisons and spearman rank correlation analyses.Reliability analyses were conducted using Cronbach′s alpha coefficients,split-half reliability Spearman-Brown coefficients.Structural validity analyses were conducted using exploratory factor analysis.Results The Chinese version of WHO ICOPE screening tool contained 6 items and 8 questions.A statistically significant difference in the scores for each item between the high group(42 cases)and the low group(60 cases)(P<0.05)was observed through the extreme group comparison method,and Spearman′s rank correlation analysis showed a positive correlation between the scores on each item and the total score(P<0.001).The reliability test showed that the Cronbach′s alpha coefficient was 0.612,and the range of Cronbach′s alpha coefficient after deleting any of the items was between 0.514 and 0.579,suggesting that there were no items that needed to be deleted;and the Spearman-Brown split-half coefficient was 0.683.Exploratory factor analysis extracted 2 common factors with initial eigenvalues>1,and the variance contributions of them were all>20%,with a cumulative variance contribution of 53.85%.Conclusions The reliability and validity of the Chinese version of WHO ICOPE screening tool is good,and can be used for screening the decline of intrinsic capacity.
