精简版流调中心抑郁量表在社区老年人中的信效度评价

Reliability and construct validity of cut version of Center for Epidemiological Studies Depression Scale (CES-D) in community elderly population

摘要:

目的  对用拉西分析法（Rasch-Derived）得来的流调中心抑郁量表（CES-D）精简版（CES-D-R）进行信效度的监测，为社区老年人抑郁自评提供一种新的更加简便的工具。方法  采用分层随机抽样，运用精简版量表CES-D-R对500名社区老年人进行问卷调查，运用SPSS 17.0和AMOS 17.0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-总分均有显著性相关，与原流调中心抑郁量表（CES-D）做校标关联分析显示均显著相关，I-CVI为0.830~1.000，S-CVI/UA为0.860、S-CVI/Ave为0.970；EFA得到四因子结构方程模型，各条目共同度为0.701～0.834，累积方差贡献率为78.913%，对模型进行CFA得到CMIN/DF<3，GFI、TLI、CFI均>0.90，RMSEA<0.08，PGFI>0.50，除CMIN和AGFI外，均达到适配标准；Cronbachα系数为0.798，4个维度的Cronbachα系数分别为0.725、0.780、0.882和0.755，分半信度系数为0.769，ICC为0.798。结论  精简版流调中心抑郁量表（CES-D-R）信效度良好，可用于社区老年人抑郁状况的评价。

Abstract:

Objective To test the reliability and construct validity of Rasch-Derived Center for Epidemiological Studies Depression Scale (CES-D-R) in community elderly population so as to provide a new kind of simple tool for them. Methods Stratified random sampling method was adopted. The CES-D-R was used for questionnaire survey in 500 community elderly people and all the data were analyzed by SPSS 17.0 and AMOS 17.0. Results Entries correlation analysis results showed that all the entries-total scores were significantly related, the CES-D-R and CES-D were significantly related, the item content validity indexes (I-CVI) were 0.830-1.000, the scale content validity indexes (S-CVI/UA) was 0.860 and S-CVI/Ave was 0.970. Four common factors from exploratory factor analysis explained 78.913% of the total variance and the communalities of the items were 0.701-0.834. Confirmatory factor analysis showed the CMIN/DF < 3; GFI, TLI and CFI > 0.90; RMSEA < 0.08; and PGFI > 0.50. Besides CMIN and AGFI, other standards achieved adaption. The Cronbach α coefficient was 0.798; Cronbach α coefficient of four dimensions were 0.725, 0.780, 0.882 and 0.755 respectively; split-half reliability coefficient was 0.769, ICC was 0.798. Conclusions CES-D-R is a reliable and valid instrument which could be used for evaluation of community elderly depression.
