抑郁-焦虑-压力量表（DASS；P. F. Lovibond & S. H. Lovibond，1995）在区分评估抑郁和焦虑症状的能力方面显示出相当大的前景。迄今为止的大部分工作都依赖于正常或主要焦虑的临床样本。为了将这项研究扩展到主要抑郁的样本，使用来自情绪障碍项目的精神病学样本 (N = 439) 来研究 DASS 的因子结构。验证性因素分析表明，21 项 DASS 的 3 因素模型得到支持。对于 42 项版本，具有交叉加载项的 3 因素模型没有显示任何实际改进。进一步的验证性分析评估了 DASS 中的项目子集代表三方模型中指定的结构的能力（L. A. Clark & D. Watson，1991）。 DASS 代表了快感缺乏和生理性过度兴奋的构造，得到了强有力的支持，并且它们的相对重要性与三方模型在理解焦虑和抑郁之间关系方面的预测一致。
The Depression-Anxiety-Stress Scales (DASS; P. F. Lovibond & S. H. Lovibond, 1995) have shown considerable promise in their ability to differentially assess depression and anxiety symptoms. Most of the work to date has relied on normal or predominantly anxious clinical samples. To extend this research to a predominantly depressed sample, a psychiatric sample from a mood disorders program (N = 439) was used to investigate the factor structure of the DASS. Confirmatory factor analyses indicated that a 3-factor model for the 21-item DASS was supported. A 3-factor model with crossloading items for the 42-item version showed no practical improvement. Further confirmatory analyses evaluated the ability of item subsets from the DASS to represent the constructs specified in the tripartite model (L. A. Clark & D. Watson, 1991). Strong support was obtained for the DASS to represent the construct of anhedonia and physiological hyperarousal, and their relative importance is consistent with predictions of the tripartite model in understanding the relationship between anxiety and depression.
