Rumination has been consistently implicated in the onset and maintenance of depression. Less work has examined rumination in the context of bipolar disorder, especially rumination about positive emotion. The present study examined rumination about negative and positive emotion in interepisode bipolar disorder (BD; n = 39) and healthy controls (CTL; n = 34). Trait rumination about positive and negative emotion, as well as experiential and physiological responses to a rumination induction, was measured. Illness course was also assessed for the BD group. Results indicated that the BD group reported greater trait rumination about positive and negative emotion compared with the CTL group, though no group differences emerged during the rumination induction. For the BD group, trait rumination about positive and negative emotion, as well as increased cardiovascular arousal (i.e., heart rate), was associated with greater lifetime depression frequency; trait rumination about positive emotion was associated with greater lifetime mania frequency. These findings suggest that interepisode BD is associated with greater rumination about positive and negative emotion, which in turn is associated with illness course.
反刍思维一直被认为与抑郁的发生和维持有关。但在双相情感障碍的背景下，尤其是关于积极情绪的反刍思维，研究工作较少。本研究考察了发作间期双相情感障碍（BD；n=39）和健康对照组（CTL；n=34）中对消极和积极情绪的反刍。测量了特质性对积极和消极情绪的反刍，以及对反刍诱导的体验和生理反应。还评估了 BD 组的疾病过程。结果表明，BD 组报告的对积极和消极情绪的特质性反刍比 CTL 组多，但在反刍诱导过程中没有出现组间差异。对于 BD 组，对积极和消极情绪的特质性反刍以及心血管兴奋（即心率）的增加与更多的终生抑郁发作频率有关；对积极情绪的特质性反刍与更多的终生躁狂发作频率有关。这些发现表明，发作间期的 BD 与更多的对积极和消极情绪的反刍有关，而反刍又与疾病过程有关。
