摘要
目的探讨中文版活动步态指数（DGI）在老年人跌倒风险评估中应用的信效度。方法采用便利抽样，对成都市两所老年院中的200名老年人采用DGI进行评估，对其信故度进行检验。结果总量表的Combaehd为0．959，分半信度系数为0．951，重测信度为0．758。各条目得分与量表总分的相关系数为0．729-0．919；因子分析共提取了1个公因子，方差贡献率为71．899％，项目因子负荷值为0．710-0．922；跌倒组得分低于无跌倒组，差异具有统计学意义；效标关联效度为0．937。结论中文版活动步态指数具有良好的信度及效度，可在我国老年人跌倒风险评估中推广应用。
Objective To test the reliability and validity of the Dynamic Gait Index-Chinese ver- sion. Methods Using convenience sampling method to assess 200 elderly people with DGI, and evaluate the reliability and validity of DGI. Results The Cornbach＇s α was 0.959, the Guttman split-half coeffi- cient was 0.951 and the test-retest reliability was 0.758. The correlation coefficients between each item with the total score ranged form 0.729 to 0.919. The factor analysis indicated the DGI was composed of 1 factor, which could explain 71.899% of total variance; the factor loading valued from 0.710 to 0.922; the score of the fall group was lower than that of the non-fall group, the difference was statistically significant, the crite- rion-related validity was 0.937. Conclusions The Chinese version of DGI has good reliability and validi- ty, it can be used as a valid tool for the assessment of elderly people＇s falling risk.
