本研究探讨了抑郁症患者所表现出的消极解释偏差的大小与他们所经历的抑郁程度有关的假设。71抑郁的参与者（得分14及以上的贝克抑郁症量表II）完成的任务，跨越三个领域的可能的负面解释：语义歧义，非言语歧义和情景歧义。回归分析显示，只有不到一半的抑郁症状严重程度的方差解释的组合负解释偏见的任务，与最强的预测抑郁症状的严重程度是负解释语义模糊时，阅读模棱两可的文字描述。辅助组分析证实，严重抑郁的人解释情感模糊的信息在更消极的方式比他们的轻度或中度抑郁的同行。这些研究结果表明，负面解释偏差的程度与抑郁症的严重程度密切相关，并且在最严重的抑郁症中，这种偏差表现得尤其强烈。本研究的发现有助于完善抑郁症的认知理论，并有助于指导治疗。(C)2016爱思唯尔有限公司版权所有
The present study investigated the hypothesis that the magnitude of negative interpretation bias displayed by those with depression is related to the degree of depression they experience. Seventy one depressed participants (scoring 14 and above on the Beck Depression Inventory II) completed tasks spanning three domains of possible negative interpretations: semantic ambiguity; nonverbal ambiguity and situational ambiguity. Regression analyses revealed that just under half of the variance in depressive symptom severity was explained by the combination of negative interpretation bias tasks, with the strongest predictor of depressive symptom severity being negative interpretation of semantic ambiguity when reading ambiguous text descriptions. Subsidiary group analyses confirmed that severely depressed individuals interpreted emotionally ambiguous information in a more negative way than did their mildly or moderately depressed counterparts. These findings indicate that the degree of negative interpretive bias is closely related to depression severity and that bias manifests especially strongly at the most severe levels of depression. Our findings may help us to refine cognitive theories of depression and be helpful in guiding therapy. (C) 2016 Elsevier Ltd. All rights reserved.
