Little is known about the nature of the relation between information-processing biases and affective traits in bipolar disorder. The present study was designed to investigate whether attentional biases are evident in persons diagnosed with bipolar disorder when they are in a positive mood state, and whether biases are related to indices of emotion regulation and to prior history of mood episodes. Ninety adults diagnosed with bipolar I disorder and 81 controls with no lifetime mood disorder underwent a positive mood induction and then completed an emotion face dot-probe task; participants in the bipolar disorder group also completed a self-report measure of responses to positive affect. Attentional bias was not related to a diagnosis of bipolar disorder or to symptom severity. Consistent with hypotheses, analyses within the bipolar group indicated that greater dampening of positive affect related to significantly less attention paid to the positively valenced faces. Discussion focuses on the potential role of affective traits in shaping attentional bias in bipolar disorder.
关于双相情感障碍中信息加工偏差与情感特质之间关系的本质，我们所知甚少。本研究旨在调查被诊断为双相情感障碍的人在处于积极情绪状态时是否存在明显的注意偏差，以及这些偏差是否与情绪调节指标和既往情绪发作史有关。90名被诊断为双相I型障碍的成年人和81名无终生情绪障碍的对照组完成了一次积极情绪诱导，然后完成了一项情绪面孔点探测任务；双相情感障碍组的参与者还完成了一份关于对积极情绪反应的自我报告测量。注意偏差与双相情感障碍的诊断或症状严重程度无关。与假设一致，双相情感障碍组内的分析表明，对积极情绪的更大抑制与对正性情绪面孔的关注度显著降低有关。讨论聚焦于情感特质在塑造双相情感障碍注意偏差中的潜在作用。
