The Beck Depression Inventory-II (BDI-II) is currently one of the most widely used measures in both research and clinical practice for assessing depression. Although the psychometric properties of the scale have been well established through many studies worldwide, so far there is no study examining the validity and reliability of BDI-II in Republic Dominican. The purpose of the present study was twofold: (a) to examine the latent structure of BDI-II by testing several competing models proposed in the literature; and (b) to provide evidence of validity and reliability of the BDI-II in Republic Dominican. Confirmatory factor analysis indicated that a bifactor model with a general depression factor and three specific factors consisting of cognitive, affective and somatic showed the best fit to the data. Internal reliability was moderate to high for all subscales and for the total scale. Scores on BDI-II discriminated between clinical and general population, supporting for external validity. Practical implications are discussed and suggestions for further research are also made.
贝克抑郁自评量表第二版(BDI-II)是目前在研究和临床实践中评估抑郁最广泛使用的量表之一。尽管该量表的心理测量特性已通过全球许多研究得到充分证实,但迄今为止,尚无研究检验 BDI-II 在多米尼加共和国的有效性和可靠性。本研究的目的有两个:(a)通过测试文献中提出的几种竞争模型,检验 BDI-II 的潜在结构;(b)为 BDI-II 在多米尼加共和国的有效性和可靠性提供证据。验证性因子分析表明,具有一般抑郁因子和由认知、情感和躯体组成的三个特定因子的双因素模型与数据拟合最好。所有分量表和总分的内部信度为中等到高度。BDI-II 的分数可以区分临床人群和一般人群,支持外部有效性。讨论了实际意义,并提出了进一步研究的建议。
