先前的研究发现，重度抑郁症患者的焦虑敏感性（AS）会升高，而焦虑敏感性的一个方面，即对认知失调的恐惧或对精神失能的恐惧，与抑郁情绪的严重程度有关。本研究试图在 142 名初步诊断为重度抑郁症的门诊患者样本中复制和扩展这些发现。在统计控制神经质的高阶效应后，发现对认知失调方面的 AS 恐惧是抑郁情绪严重程度的重要预测因子。然而，进一步的分析提供了强有力的证据，表明 AS 方面的影响是由对抑郁情绪的沉思所介导的。结果是在“抑郁敏感性”的背景下讨论的，这是一种拟议的认知结构，可能是沉思抑郁症状的认知过程的基础。
Previous research has found anxiety sensitivity (AS) to be elevated in persons with major depression, and a facet of AS referred to as fear of cognitive dyscontrol or fear of mental incapacitation has been associated with severity of depressed mood. The present study sought to replicate and extend these findings in a sample of 142 outpatients with a primary diagnosis of Major Depressive Disorder After statistically controlling for the higher order effect of neuroticism, the AS fear of cognitive dyscontrol facet was found to be a significant predictor of severity of depressed mood. However, further analysis provided strong evidence that the effect of this AS facet is mediated by rumination over depressed mood. Results are discussed in the context of "depression sensitivity," a proposed cognitive structure that may underlie the cognitive process of rumination over depression symptoms.
