目的编制流调中心抑郁量表(Center for Epidemiologic Studies Depression Scale,CES—D)中文简版。方法以全国分层随机取样的30801个普通人群样本和415个精神疾患样本为基础,结合独立样本t检验结果与量表信效度指标编制简版,并提出抑郁症状检出的划界分。结果CES—D中文简版共9题,内部一致信度在0.85—0.88,重测信度为0.49(P〈0.001),各条目与总分相关均大于0.5,与原量表相关系数0.94。0.96(P〈0.001)。首诊抑郁患者的量表分高于服药抑郁患者和普通人群。简版量表验证了两维度的因素结构,即积极症状与消极症状。量表以10分和17分为抑郁倾向和抑郁高风险的划界分。结论流调中心抑郁量表9题中文简版的信效度良好,可以在各年龄群体中进行抑郁水平的施测。

Objective To develop a short Chinese version of the center for epidemiological studies de- pression scale(CES-D). Method A stratified random nationwide sample with 30801 normal people and a mental- ly ill sample with 415 patients were tested. Items in the short version were chosen according to both the result of in- dependent t-test in current study and the result of reliance and validity. Cut-off scores were offered to check up de- pressions. Result The internal consistency reliability of the 9-item Chinese version CES-D ranged from 0.85 to 0.88.The test-retest reliability was 0.49(P〈0.001 ). All item-total correlations were higher than 0.5.The correlation between sumscores of the original scale and sumscores of the Chinese short version ranged from 0.94 to 0.96(P〈 0.001 ) in all the samples.The sum scores of initial diagnosis depression sample were significantly higher than that of treated depression sample and common sample.A two-dimension structure was testified.The cut-off scores of the short version were 10 and 17.Conclusion The 9-item Chinese version of CES-D can be used in various samples with reliable and valid effect.
