据报道，抑郁症和焦虑症有重叠的症状，在概念上是相互关联的。解释这种关联的最突出的理论发展之一是克拉克和沃森的三方模型（Journal of Abnormal Psychology，100：316-336，1991），该模型假定这两种疾病和消极情绪共享消极情感（NA）的潜在成分。本研究有两个目的，（a）通过对抑郁焦虑和压力量表（DASS-21）（Lovibond and Lovibond 1995）的验证性因素分析（CFA），比较三因素结构与竞争模型，（B）探索DASS-21的心理测量学特性。DASS-21由4039名年龄在12-18岁之间的澳大利亚年轻人的代表性样本完成，作为南澳大利亚州青年心理健康调查（SAYMHS）的一部分，南澳，澳大利亚。数据的最佳拟合模型包括快感缺失抑郁、生理性过度觉醒和一般NA。DASS-21的心理测量学特性非常好，具有稳定和可解释的因素结构和良好的内部一致性。目前的研究结果表明，抑郁和焦虑的理论三方结构是强大的，适用于澳大利亚青年。这些研究结果的诊断，临床和理论意义进行了讨论。
It has been reported that depression and anxiety have overlapping symptoms and are conceptually interrelated. One of the most prominent theoretical developments that explain this association is Clark and Watson's tripartite model (Journal of Abnormal Psychology, 100:316-336, 1991) that posits these two disorders and negative emotions share a latent component of negative affect (NA). The current study had two aims, (a) to compare a tripartite factor structure against competing models by Confirmatory Factor Analysis (CFA) of the Depression Anxiety and Stress Scales (DASS-21) (Lovibond and Lovibond 1995), and (b) explore the psychometric properties of the DASS-21. The DASS-21 was completed by a representative sample of 4039 young Australians, aged 12-18 years, as part of the South Australian Youth Mental Health Survey (SAYMHS), South Australia, Australia. The best fitting model for the data consisted of anhedonic depression, physiological hyperarousal, and general NA. The psychometric properties of the DASS-21 were excellent with a stable and interpretable factor structure and good internal consistency. The results of the current study suggest that the theoretical tripartite structure of depression and anxiety is robust and applicable among Australian youth. The diagnostic, clinical and theoretical implications of these findings are discussed.
