Recent evidence suggests that reflective (i.e., distanced-why), as compared to ruminative (i.e., immersed-why), processing of negative memories is associated with reductions in negative affect. The present study extended this line of work by examining the effect of these two processing conditions on positive memories among persons with bipolar disorder (BD; n = 27) and a healthy control group (CT; n = 27). After a resting baseline period, participants were instructed to recall a happy autobiographical memory. Using a within-subjects design, participants were asked to process the happy memory in two different experimental conditions (reflective, ruminative) while their experiential, behavioral, and autonomic responses were measured. Consistent with hypotheses, reflective processing was associated with lower self-reported positive affect, positive thoughts, and heart rate compared to ruminative processing for all participants. When current symptoms were controlled for, BD participants reported greater positive affect across both conditions relative to CT participants. Prospective studies are needed to test the extent to which processing of positive emotion contributes to the course of symptoms in bipolar disorder.
最近的证据表明，与沉思（即，沉浸于“为什么”）相比，消极记忆的反思性（即，抽离于“为什么”）处理与负面情绪的减少有关。本研究通过检查这两种处理条件对双相情感障碍患者（BD；n=27）和健康对照组（CT；n=27）的积极记忆的影响，扩展了这一研究方向。在休息的基线期后，参与者被要求回忆一个愉快的自传体记忆。使用被试内设计，要求参与者在两种不同的实验条件（反思性、沉思性）下处理愉快的记忆，同时测量他们的体验、行为和自主反应。与假设一致，与沉思性处理相比，所有参与者的反思性处理与自我报告的积极情绪、积极想法和心率降低有关。当控制当前症状时，BD 参与者在两种条件下的积极情绪报告均高于 CT 参与者。需要前瞻性研究来检验积极情绪处理对双相情感障碍症状发展的影响程度。
