Depressive symptoms have been recognized as one of the most frequent complaints among natural disaster survivors. One of the most frequently used self-report measures of depressive symptoms is the Center for Epidemiologic Studies Depression Scale (CES-D). To our knowledge, no study has yet examined the factor structure, reliability, and validity of the CES-D in a sample of natural disaster survivors. Thus, the present study investigated the factor structure, reliability, and validity of a Korean language version of the CES-D (KCES-D) for natural disaster survivors.
We utilized two archived datasets collected independently for two different periods in 2008 in the same region of Korea (n = 192 for sample 1; n = 148 for sample 2). Participants were survivors of torrential rains in the mid-eastern region of the Korean peninsula. For analysis, Samples 1 and 2 were merged (N = 340). Confirmatory factor analysis was performed to evaluate the one-factor model, the four-factor model, and the bi-factor models, as well as the second-order factor model. Composite reliability was computed to examine the internal consistency of the KCES-D total and subscale scores. Finally, Pearson's r was computed to examine the relationship between the KCES-D and the trauma-related measures.
The four-factor model provided the best fit to the data among the alternatives. The KCES-D showed adequate internal consistency, except for the 'interpersonal difficulties' subscale. Also regarding concurrent validity, weak to moderate positive correlations were observed between the KCES-D and the trauma-related measures.
The results support the four-factor model and indicate that the KCES-D has adequate psychometric properties for natural disaster survivors. If these findings are further confirmed, the KCES-D can be used as a useful, rapid, and inexpensive screening tool for assessing depressive symptoms in natural disaster survivors.
抑郁症状已被公认为自然灾害幸存者中最常见的主诉之一。流行病学研究中心抑郁量表（CES-D）是最常用的抑郁症状自评量表之一。据我们所知，尚无研究在自然灾害幸存者样本中检验CES-D的因子结构、信度和效度。因此，本研究调查了针对自然灾害幸存者的韩语版CES-D（KCES-D）的因子结构、信度和效度。
我们利用了2008年在韩国同一地区独立收集的两个存档数据集（样本1为n = 192；样本2为n = 148）。参与者是朝鲜半岛中东部地区暴雨的幸存者。为了进行分析，将样本1和样本2合并（N = 340）。进行验证性因子分析以评估单因子模型、四因子模型、双因子模型以及二阶因子模型。计算组合信度以检验KCES-D总分和子量表得分的内部一致性。最后，计算Pearson相关系数r以检验KCES-D与创伤相关测量指标之间的关系。
在备选模型中，四因子模型对数据的拟合最佳。KCES-D显示出足够的内部一致性，但“人际困难”子量表除外。关于同时效度，在KCES-D与创伤相关测量指标之间观察到弱至中度的正相关。
结果支持四因子模型，并表明KCES-D对自然灾害幸存者具有足够的心理测量学特性。如果这些发现得到进一步证实，KCES-D可作为一种有用、快速且廉价的筛查工具，用于评估自然灾害幸存者的抑郁症状。
