中文版老年人风险评定量表评估社区失能老年人功能的信效度

Reliability and validity of Chinese version elderly at risk rating scale for functional assessment among community disabled elderly

目的 探究中文版老年人风险评定量表（EARRS）评估社区失能老年人功能的信效度.方法 通过正向翻译、回译、专家小组评议等步骤对EARRS进行汉化和文化调试,得到中文版EARRS,包括躯体功能、心理功能和社会功能等3个维度;以改良Barthel指数作为效标,同时使用2个量表对杭州市382例社区失能老年人进行评估,计算中文版EARRS的重测信度、内部一致性信度、分半信度、内容效度和效标关联效度.结果 中文版EARRS及其3个维度重测信度相关系数均＞0.8（P＜0.01）;Cronbach系数均＞0.8,Spearman-brown系数和Guttman分半系数均＞0.7;中文版EARRS各维度得分与总分均呈正相关（r=0.683～0.849,P＜0.01）.中文版EARRS与改良Barthel指数的相关性良好（r=-0.692,P＜0.01）.结论 中文版EARRS评估社区失能老年人功能的信效度良好.

Objective To evaluate the reliability and validity of the Chinese version elderly at risk rating scale （EARRS） for disability assessment in community elderly.Methods The Chinese version of EARRS was developed by translation,back translation,cultural adaptation,synthesization and expert review.The Chinese version of EARRS included 3 dimensions：physical function,psychology function and social function.We evaluated 382 community disabled elderly living in Hangzhou with Chinese EARRS and the modified Barthel Index,which was used as reference.The internal consistency reliability,test-retest reliability,inter-rater reliability,content validity and criterion validity of the Chinese EARRS were assessed.Results The test-retest reliability of each dimension and total score were higher than 0.8 （P＜0.01）.The Cronbach＇s α coefficient was higher than 0.8.Spearman-Brown coefficient and Guttman split-half coefficient were higher than 0.7.Pearson correlation coefficient of the total score and each dimension with modified Barthel Index were-0.613～-0.791,which had reached statistical significance.Conclusion The Chinese version of EARRS has good reliability and validity and can be used as a valid tool for functional evaluation among community disabled elderly.
