目的：我们试图在终末期肾病（ESRD）患者样本中检查贝克抑郁量表-II（BDI）的几个竞争因素结构，其中因素结构的定义很差，尽管抑郁症状很常见。此外，人口统计学和临床相关的因素进行了examined.Methods：BDI管理的460终末期肾病患者参加4英国肾脏中心的临床样本。采用验证性因子分析对BDI因子结构的竞争模型进行了评价。最佳拟合模型由一般抑郁因子和正交认知、躯体因子组成，一般抑郁因子可解释各项目间沿着方差的81（G-S-C模型，CFI=.983，TLI=.979，RMSEA=.037），分别解释了8%和9%的共同方差。年龄、糖尿病和种族与认知因素显著相关，而白蛋白、透析充分性和种族与躯体因素相关。没有人口统计学或临床变量与一般factor.Conclusion：一般因素模型提供了最佳拟合和概念上最可接受的解释的BDI。此外，认知和躯体因素似乎与特定的人口统计学和临床因素有关。(C)2011 Elsevier Inc.

Objective: We sought to examine several competing factor structures of the Beck Depression Inventory-II (BDI) in a sample of patients with End-Stage Renal Disease (ESRD), in which setting the factor structure is poorly defined, though depression symptoms are common. In addition, demographic and clinical correlates of the identified factors were examined.Methods: The BDI was administered to clinical sample of 460 ESRD patients attending 4 UK renal centres. Competing models of the factor structure of the BDI were evaluated using confirmatory factor analysis.Results: The hest fitting model consisted of general depression factor that accounted for 81% of the common variance between all items along with orthogonal cognitive and somatic factors (G-S-C model, CFI=.983, TLI=.979, RMSEA=.037), which explained 8% and 9% of the common variance, respectively. Age, diabetes, and ethnicity were significantly related to the cognitive factor, whereas albumin, dialysis adequacy, and ethnicity were related to the somatic factor. No demographic or clinical variable was associated with the general factor.Conclusion: The general-factor model provides the best fitting and conceptually most acceptable interpretation of the BDI. Furthermore, the cognitive and somatic factors appear to be related to specific demographic and clinical factors. (C) 2011 Elsevier Inc. All rights reserved.
