Epidemiological studies have consistently reported that depressive and anxiety disorders co-occur frequently. This paper reviews the evidence for three models that have been proposed to explain the relation between these two conditions-the tripartite, the approach-withdrawal, and valence-arousal models. Specifically, we focus on predictions that the three models generate for cross-sectional studies, prospective and family/twin studies of personality, and EEG studies. In sum, no model was strongly supported across all types of studies, though specific aspects of each model were. Because of the heterogeneity of depression and anxiety disorders, a model with 2-4 factors or dimensions may not be sufficient to explain the relation between the two conditions.

抑郁与焦虑之间的关系：对三方，进近退出和化合价模型的评估。

流行病学研究一致报告抑郁症和焦虑症经常并发。本文回顾了为解释这两个条件之间的关系而提出的三种模型的证据，即三方模型，进近撤回模型和化合价模型。具体而言，我们专注于这三种模型针对横断面研究，前瞻性和家庭/双胞胎人格研究以及EEG研究生成的预测。总而言之，尽管每种模型的特定方面都得到了支持，但在所有类型的研究中均未大力支持任何模型。由于抑郁症和焦虑症的异质性，具有2-4个因素或维度的模型可能不足以解释这两种情况之间的关系。
