流调中心抑郁量表在农村女性中的因素结构和信效度

目的探究流调中心抑郁量表 (CES-D)用于筛查农村女性抑郁情况时的因素结构并评价其信、效度。方法首先计算分别删除积极情绪4个条目后的其余条目的Cronbach's α 系数，以及积极情绪维度与其他维度的相关性，以评价积极情绪维度存在的合理性。然后对数据进行4种不同模型（Radolff四因素结构、Guarnaccia三因素结构、Yen三因素结构、Lan两因素结构）的拟合，通过比较RMESA、NFI、IFI、CFI等指标选出最佳模型后，采用Cronbach's α 系数、相关系数评价该模型下量表的内部一致性信度，采用会聚效度、区别效度和结构效度评估量表的效度。结果 CES-D量表的积极情绪维度存在合理。Radloff四因素结构对当前数据的拟合效果最好且验证性因子分析结果为NFI=0.895、IFI=0.908、CFI=0.908、RMSEA=0.058。总的Cronbach's α 系数为0.889，各维度的α 系数范围为0.687~0.735；各维度与总分的相关系数为0.378~0.892。会聚效度定标试验成功率为85.71%~100%，区别效度的定标试验成功率为100%。结论 CES-D用于筛查农村妇女抑郁情况时最适于Radloff四因素结构模型且具有较好的信度与效度。

英文摘要:

Objective To test the reliability and construct validity of the Center for Epidemiological Studies Depression Scale (CES-D) in a rural Chinese women population. Methods To determine the propriety of positive questions in the CES-D, Cronbach's α coefficients were calculated when each of the four positive questions was deleted. Correlations between the positive affection subscale and other subscales were also tested. The four factor structure of the scale was tested using RMESA, NFI, IFI, and CFI in a confirmatory factor analysis. The internal consistency and convergent and discriminant validities of the scale were further assessed based on the four-factor structure. Results Propriety of the positive affection subscale was evident. The data fit well with the four-factor structure proposed by Radloff. The factor analysis confirmed the theoretical assumption (NFI=0.895, IFI=0.908, CFI = 0.908, RMSEA = 0.058). The Cronbach's α coefficients of the four-factor scale ranged from 0.687 to 0.735 (0.889 for the entire scale). The subscales had a correlation coefficient of 0.378-0.892 with the total score of the scale. An 85.71%-100% success rate of convergent validity experiment and 100% success rate of discriminant validity experiment was found. Conclusion CES-D is a valid scale with a four-factor structure for depression screening in Chinese rural women.
