中文版抑郁应对自我效能感量表的信效度研究

Reliability and validity of Chinese version of the Depression Coping Self-Efficacy Scale

目的汉化英文版抑郁应对自我效能感量表（DCSES）并评价中文版量表的信效度。方法按照量表翻译模式，对英文版DCSES进行汉化、文化调适，并将中文版DCSES应用于264例抑郁症患者中，对测定结果进行信效度分析。结果中文版DCSES的整体Cronbach仅系数为0．926，各维度的Cronbach仅为0．930、0．908、0．921、0．945；分半信度系数为r=0．865，重测信度为0．752，各维度的重测信度为0．801、0．718、0．729、0．745、0．766（P〈0．01）。各条目得分与量表总分的相关系数为0．603—0．748（P〈0．01）；探索性因子分析共提取5个公因子，累积方差贡献率为58．617％，各条目在其公因子上的因子载荷为0．447～0．762，均〉0．4。结论中文版DCSES具有良好的信效度，可用其评价患者的抑郁应对自我效能感水平。

Objective To translate the English version of the Depression Coping Self-Efficacy Scale （DCSES） into Chinese and test the reliability and validity of the Chinese version of DCSES in patients with depression. Methods Totally 264 patients with depression were recruited and were investigated by the Chinese version of DCSES. Results The total internal consistency coefficient of the Chinese version of DCSES was 0.926, while each dimension were 0.930, 0.908, 0.921, 0.945; split half reliability coefficient was 0.865; the test-retest was 0.752, while each dimension were 0.801, 0.718, 0.729, 0.745, 0.766 （P〈0.01）; the item-scale correlation ranged from 0.603 to 0.748（P〈0.01）. Factor analysis got five factors, which explained 58.617% of the total variance. All factor loadings, ranging from 0.447 to 0.762, were statistically significant in the five-factor model and greater than 0.4. Conclusions The Chinese version of DCSES has been proved to be reliable and valid. It can be used as a valid tool for the measurement of the coping self-efficacy in patients with depression.
