Laboratory studies suggest that bipolar disorder is characterized by emotion dysregulation, yet emotion disturbance has not been systematically described using more ecologically valid methods. Using an experience-sampling approach, we therefore sought to investigate positive and negative emotionality, emotion regulation strategies, and functioning among remitted individuals with bipolar I disorder (BD; n = 31) compared with both healthy controls (CTL; n = 32) and remitted individuals with major depressive disorder (MDD; n = 21). Hierarchical linear modeling analyses of self-report data spanning a 6-day consecutive period revealed that the BD group aligned with the CTL group in reporting greater positive emotionality than the MDD group, but aligned with the MDD group in reporting greater negative emotionality than the CTL group. Furthermore, the BD and MDD groups reported greater general use of emotion regulation strategies than the CTL group. These findings suggest that BD is characterized by amplified emotionality as well as increased efforts to regulate emotions in everyday life. Discussion focuses on implications for BD, as well as identification of unique (disorder-specific) and shared (transdiagnostic) features of emotion disturbance.
实验室研究表明，双相情感障碍的特征是情绪调节障碍，但尚未使用更具生态效度的方法系统地描述情绪障碍。因此，我们采用经验取样法，旨在比较缓解期的双相 I 型障碍（BD；n=31）个体与健康对照组（CTL；n=32）和缓解期的重性抑郁障碍（MDD；n=21）个体，调查其正性和负性情绪、情绪调节策略和功能。跨越 6 天连续时间的自我报告数据的层次线性建模分析显示，BD 组与 CTL 组报告的正性情绪比 MDD 组更强，但与 MDD 组报告的负性情绪比 CTL 组更强。此外，BD 和 MDD 组报告的一般情绪调节策略的使用多于 CTL 组。这些发现表明，BD 的特征是情绪放大，以及在日常生活中更努力地调节情绪。讨论集中在对 BD 的影响，以及情绪障碍的独特（特定于障碍）和共享（跨诊断）特征的识别。
