中文版照护依赖量表在失能老年人中应用的信度与效度分析

Reliability and validity of the Chinese-version care dependency scale for rehabilitation among old disabled patients

目的:引入中文版照护依赖量表(CDS-R),分析其在失能老年人评定中的信度与效度。方法:通过正向翻译、综合、回译、研究小组评议和专家评议等步骤对CDS-R进行汉化和文化调试,形成中文版CDS-R。采用目的抽样法,运用Barthel指数与PULSES评定量表作为效标,对江苏、浙江两地区三甲医院、康复医院和养老机构共10家机构652例失能老年人进行评估与分析,其中40例失能老年人在2周后被重新评估,对测定结果分别进行信度和效度分析。结果:中文版CDS-R有15个条目,各条目与量表总分的相关系数值为0.83—0.93(P<0.01)Cronbach'sɑ系数为0.98,Guttman折半系数为0.91,重测信度为0.73,探索性因子分析得出1个公因子,累计方差贡献率81.91%。CDSR与Barthel指数、PULSES评定量表的相关性分别为0.91和-0.85,均具有显著性意义。结论:中文版CDS-R量表具有良好的信度、效度,适合在中国文化背景下评估失能老年人的照护依赖情况。

Objective： To introduce the Chinese-version of care dependency scale for rehabilitation （CDS-R） and to analyse it＇s validity and reliability in elderly patients with disabilities. Method：A culturally adaptation for the Chinese version of CDS-R was developed. The translation process in- cluded independent translation, synthesization, back translation, a research review and an expert review. A total of 652 elderly patients with disabilities living in top three hospitals, rehabilitation hospitals and long-term care homes in Jiangsu and Zhejiang provinces were selected by purposive sampling and were asked to fill out the Chinese CDS-R. At the same time the Barthel index and PULSES were measured as criterion. Among them, 40 patients were re-assessed 2 weeks later. Result：The Chinese version of CDS-R has 15 items. The correlation coefficient（r） of each item and total score were 0.83--0.93（P〈0.01）. The Cronbach＇s ct was 0.98 for the total scale, the Guttman split-half was 0.91 and the test-retest correlation was 0.73. One factor was extracted by principal components analysis, which contribut- ed 81.91%. The correlation coefficient（r）s between CDS-R with Barthel Index and PULSES were separately 0.91 and -0.85, which had reached statistical significance. Conclusion：The Chinese-version of care dependency scale for rehabilitation has good psychometric characteris-tics and can be used as a valid tool for the measurement of care dependency among Chinese elderly patients with disabilities.
