目的建立与国际功能、残疾和健康分类(ICF)条目相匹配的中国老年人失能失智分级标准,同时编制能使患者、家属、医疗卫生工作者一致理解的可视化评估工具并验证其信效度。
方法通过参考相关文献及专家咨询,初步确立5种老年人失能失智分级、ICF条目及可视化评估工具;随后通过问卷法进行分级合理度及与插图、GIF动图、ICF条目匹配度调查。通过项目分析筛选条目,图文匹配效度检验确定可视化评估工具匹配程度,内部一致性信度或重测信度进行信度检验,内容效度进行效度检验。
结果每种失能失智分级初始分为5级,经过专家咨询修改后分为4级,并对相关描述语进行简化;所有条目与各部分总分的Pearson相关系数均大于0.3,且差异有统计学意义(均 P<0.05);插图及GIF动图与相关描述语匹配度的平均分、众数均大于3,一致性率均大于50%,且两者在8个条目上的差异具有统计学意义;反映内部一致性的Cronbach's α系数均大于0.60,反映重测信度的组内相关系数均大于0.70;反映内容效度的问卷水平内容效度指数均大于0.90,条目水平内容效度指数均大于0.78。
结论初步确立了符合ICF的中国老年人失能失智分级标准及可视化评估工具,且具有良好的信效度;两种可视化评估工具中GIF动图更受欢迎,更容易帮助理解。
ObjectiveTo establish Chinese grading standards for elderly disability and dementia, in accordance with the International Classification of Functioning, Disability and Health(ICF)items, and to develop visual assessment tools that can be easily understood by patients, family members, and health workers.The aim is to verify the reliability and validity of these tools.
MethodsIn this study, we established five categories of elderly disability classification, along with corresponding ICF items and visual evaluation tools.The appropriateness and compatibility of the tools were assessed using questionnaires, which included illustrations, GIF dynamic pictures, and ICF items.Correlation analysis was conducted to screen the items, and the validity of the visual evaluation tools was determined through a picture-text matching validity test.Reliability was evaluated using internal consistency or test-retest reliability, and validity was assessed through content validity.
ResultsEach grade of disability was initially divided into five levels.However, after expert consultations and classification revision, each level was ultimately simplified into four levels with clearer descriptions.The Pearson correlation coefficients between all items and the total scores of each part were found to exceed 0.3, and the difference was statistically significant(all P<0.05).The average and mode of the illustrations and GIF dynamic pictures, when matched with related descriptions, were both above 3, with consistency rates surpassing 50%.Statistical differences were observed in eight items between the two visual assessment tools.The Cronbach's α coefficients, which reflect internal consistency, were all above 0.60.The intra-group correlation coefficients, which indicate test-retest reliability, were all greater than 0.70.The content validity index of the questionnaire at the overall level was above 0.90, while the item-level content validity index was more than 0.78.
ConclusionsThe Chinese grading standards for elderly disability and dementia, which are aligned with the ICF, have been preliminarily established.Visual assessment tools have also been developed, which demonstrate good reliability and validity.Among the two visual assessment tools, GIF dynamic pictures were found to be more popular and easier to understand.
