主观记忆障碍量表在社区老年人中的信效度评价

Reliability and validity of Chinese version of Subjective Memory Complaint Questionnaire in community elderly population

摘要:

目的对主观记忆障碍量表（SMCQ）进行汉化，并检测其信效度。方法采用方便抽样法，运用SMCQ 对356 名农村社区老年人进行问卷调查，运用SPSS23.0 和AMOS23.0 软件对所得数据进行统计分析。结果条目相关性分析结果显示，所有条目- 总分均有相关性，探索性因子分析得到三因子结构方程模型，累计方差贡献率为65.442%，验证性因子分析得到χ2/ 自由度（CMIN/DF）<3、渐进残差均方和平方根（RMSEA）<1.00、非规范拟合指数（TLI）、增值拟合指数（IFI）、比较拟合指数（CFI）均>0.90，简约拟合指数（PGFI）>0.50，除CMIN、GFI 和AGFI 外，均达到适配标准；SMCQ 的Cronbachα系数为0.872，分半信度为0.757。结论SMCQ信效度良好，可用于我国社区老年人主观记忆障碍状况的评价。

Abstract:

Objective To translate Subjective Memory Complaint Questionnaire (SMCQ) into Chinese, and test the reliability and validity of Chinese Version of SMCQ so as to provide a new kind of tool to evaluate subjective memory complaint of Chinese elderly.

Results Entries correlation analysis results showed that all the entries and total scores were significantly related. Three common factors from exploratory factor analysis explained 65.442% of the total variance. Confirmatory factor analysis showed the CMIN/DF <3, RMSEA <1.00; TLI, IFI and CFI all >0.90; and PGFI >0.50. Besides CMIN, GFI and AGFI, others met the adaption standards. The Cronbach's α coefficient was 0.872, the split-half reliability coefficient was 0.757. Conclusions SMCQ is reliable and valid. It could be used for evaluation of subjective memory complaint in the community elderly.
