抑郁症中异常情绪处理的多种模型已经被提出。然而，目前还不清楚这些模型中哪一种最适用于亚临床抑郁症状的情绪障碍。目前的研究使用了一系列心理生理学测量和图片观看范式中的情绪评级，以检验亚临床抑郁症状中情绪障碍的低觉醒、低积极情绪、高负面情绪或情绪情境不敏感模型是否得到了最大支持。愉悦-中性图片的耳后反射和皮肤电导反应增强(测量低积极情绪)、总体皮肤电导幅度和LPP幅度(测量唤醒不足)、愉快-厌恶效价等级(测量情绪背景不敏感性)和厌恶-中性唤醒等级(测量高度负面情绪)都与抑郁症状负相关。其中，耳后反射增强和整体LPP波幅在其他指标中与抑郁症状的相关性逐渐增强。在控制了内化障碍的其他症状后，耳后反射增强、总皮肤电导大小和厌恶减中性唤醒评分与抑郁症状的相关性逐渐增加。虽然没有一个模型是明确优于的，但低积极情绪和低觉醒模型从生理测量和症状报告中得到的支持最多，自我报告数据的模式与情绪情境不敏感模型一致。
Multiple models of aberrant emotional processing in depression have been advanced. However, it is unclear which of these models best applies to emotional disturbances in subclinical depressive symptoms. The current study employed a battery of psychophysiological measures and emotional ratings in a picture viewing paradigm to examine whether the underarousal, low positive emotion, heightened negative emotion, or emotion context insensitivity model of emotional dysfunction in subclinical depressive symptoms received greatest support. Postauricular reflex and skin conductance response potentiation for pleasantminus neutral pictures (measuring low positive emotion), overall skin conductance magnitude and LPP amplitude (measuring underarousal), and pleasant minus aversive valence ratings (measuring emotion context insensitivity) and aversive minus neutral arousal ratings (measuring heightened negative emotionality) were all negatively related to depressive symptomatology. Of these, postauricular reflex potentiation and overall LPP amplitude were incrementally associated with depressive symptoms over the other measures. Postauricular reflex potentiation, overall skin conductance magnitude, and aversive minus neutral arousal ratings were incrementally associated with depressive symptomatology after controlling for other symptoms of internalizing disorders. Though no model was unequivocally superior, the low positive emotion and underarousal models received the most support from physiological measures and symptom reports, with self-report data matching patterns consistent with the emotion context insensitivity model.
