Research has consistently documented that depressed individuals process information in a negatively biased manner. There is little evidence, however, concerning whether these biases represent risk factors for depression, as is hypothesized by cognitive models. In the present study we investigated whether a particular cognitive bias observed in currently depressed individuals, the tendency to interpret ambiguous information negatively, characterizes daughters of depressed mothers, a population known to be at increased risk for depression. Following a negative mood induction, young daughters of depressed and never-disordered mothers completed two information-processing tasks in which their interpretations of emotionally ambiguous stimuli were evaluated. Daughters of depressed mothers interpreted ambiguous words more negatively and less positively, and ambiguous stories more negatively, than did daughters of never-disordered mothers. These results provide support for cognitive vulnerability models of depression.
研究一直表明，抑郁个体以负性偏向的方式处理信息。然而，几乎没有证据表明这些偏向是否如认知模型所假设的那样，是抑郁症的风险因素。在本研究中，我们调查了当前抑郁个体中观察到的一种特定认知偏向，即对模糊信息进行负性解释的倾向，是否也存在于抑郁症母亲的女儿身上，这一群体已知患抑郁症的风险增加。在诱发消极情绪后，抑郁症母亲和从未患过精神疾病母亲的年轻女儿完成了两项信息处理任务，在这些任务中评估她们对情绪模糊刺激的解释。与从未患过精神疾病母亲的女儿相比，抑郁症母亲的女儿对模糊词语的解释更消极、更不积极，对模糊故事的解释也更消极。这些结果为抑郁症的认知易感性模型提供了支持。
