Life events play a significant role in affecting mood symptoms of people with bipolar disorder (BD). However, we lack empirical data about the associations among disorder, mood state, behavioral activation system (BAS) sensitivity, and psychosocial functioning level. Thus, the present study aimed to identify the role of coping flexibility with BAS activating stimuli in relation to mood states among a sample of individuals with BD (n = 90) and a healthy control group (n = 90). Through multiple regressions, the moderating role of coping flexibility was determined. Findings showed that coping flexibility had an additional value in predicting mood states beyond BAS sensitivity and psychosocial functioning level. Specifically, perceived controllability was considerably important for the BD group, whereas fit index was crucial in the controls. In addition, a moderation analysis showed that perceived controllability alleviated the effects of BD diagnosis, BAS sensitivity, and psychosocial functioning level on mood states. Theoretically, this study helps integrate the concept of coping flexibility into the BAS dysregulation theory as it applies to BD. The practical implication for enhancing mindfulness practice is also discussed.
生活事件在影响双相情感障碍（BD）患者的情绪症状方面起着重要作用。然而，我们缺乏关于障碍、情绪状态、行为激活系统（BAS）敏感性和心理社会功能水平之间关联的经验数据。因此，本研究旨在确定在 BD 患者样本（n=90）和健康对照组（n=90）中，用 BAS 激活刺激应对灵活性与情绪状态之间的关系中应对灵活性的作用。通过多元回归，确定了应对灵活性的调节作用。研究结果表明，应对灵活性在预测情绪状态方面除了 BAS 敏感性和心理社会功能水平之外还有额外的价值。具体来说，可感知的可控性对 BD 组非常重要，而适合度指数对对照组至关重要。此外，调节分析表明，可感知的可控性减轻了 BD 诊断、BAS 敏感性和心理社会功能水平对情绪状态的影响。从理论上讲，这项研究有助于将应对灵活性的概念整合到适用于 BD 的 BAS 失调理论中。还讨论了增强正念实践的实际意义。
