心理弹性量表简版在社区老年人中的信效度检验

The reliability and validity of 10-item Connor-Davidson resilience scale in the community-dwelling older adults

目的探讨心理弹性量表简版（10-item connor-davidson resilience scale，CD-RISC-10）在我国社区老年人中使用的信度和效度。方法采用心理弹性量表简版、简版老年抑郁量表和自编基本情况表对随机抽取成都市16个社区中的620名老年人进行调查。结果项目分析显示，10个题项的鉴别力均显著（t=6．84~13．57，P〈0．01）；探索性因素分析提取出2个因素（力量性和坚韧性），累积方差解释率为42．32％；验证性因素分析显示2因素模型拟合指数为：X^2／df=1．518（P〈0．001），CFI=0．964，TLI=0．948，IFI=0．965，NFI=0．904，RMSEA=0．042；总量表和两个因素的Cronbach＇s α分别为0．737、0．673和0．585；总量表及力量性、坚韧性2因素在半个月后的重测信度为：0．974，0．932，0．941（P〈0．01）。结论CD-RISC-10具有良好的信度和效度，使用简易方便，是测量社区老年人心理弹性的有效工具。

Objective To evaluate the reliability and validity of 10 items Connor-Davidson resilience scale （CD-RISC-10） in the community-dwelling older adults. Methods Totally 620 community-dwelling older adults randomly chosen from 16 communities in Chengdu city were investigated by CD-RISC-10, the geriatric depression scale short form （GDS-SF） and self-made basic condition questionnaire. Results The discrimination of the 10 items was statistically significant（ t= 6.84-13.57,P〈0.01 ）. Exploratory factor analysis showed two factors （strength and hardiness） were extracted, and the cumulative variance interpreta- tion rate was 42. 32%. Confirmatory factor analysis showed that model index of two sub-factors （ X^2/df= 1. 518（P〈0. 001） ,CFI =0. 964,TLI =0. 948,IFI =0. 965,NFI =0. 904,RMSEA=0. 042）. Cronbach＇s α of the total scale and the two sub-factors were 0. 737,0. 673 and 0. 585 respectively. After half a month, the retest reliability coefficients of the total scale and the two sub-factors were O. 974,0. 932 and 0. 941 （P〈 0.01 ）. Conclusion The CD-RISC-10 scale has acceptable reliability and validity,with using easily and conveniently. Therefore,it is an effective tool for measuring the resilience of the community-dwelling older adults.
