There is a growing interest in the transdiagnostic trait of rumination. However, few studies have directly examined the ruminative response in the diagnosis of disorders other than major depression, such as anxiety disorders and bipolar disorders. Even fewer studies have done so in a large, clinical sample.
Patients with major depressive disorder (MDD), bipolar disorder (BPD), panic disorder with/without agoraphobia (PD), and generalized anxiety disorder or obsessive-compulsive disorder (GAD/OCD) were compared using the Ruminative Response Scale (RRS), Hamilton Rating Scale for Depression (HAM-D), and Hamilton Rating Scale for Anxiety (HAM-A).
The PD group displayed the lowest levels of rumination even when depression and anxiety symptoms were treated as a covariate. The BPD group displayed higher levels of rumination than the MDD group.
A heightened ruminative response was not only found among individuals with MDD, but also among those with BPD and GAD/OCD; this might indicate ineffective thought control.
反刍特质越来越受到关注。然而，很少有研究直接在除重度抑郁症以外的疾病（如焦虑症和双相情感障碍）的诊断中检验反刍反应，在大型临床样本中进行此类研究的则更少。
使用反刍反应量表（RRS）、汉密尔顿抑郁量表（HAM-D）和汉密尔顿焦虑量表（HAM-A）比较了患有重度抑郁症（MDD）、双相情感障碍（BPD）、伴有/不伴有广场恐怖症的惊恐障碍（PD）以及广泛性焦虑症或强迫症（GAD/OCD）的患者。
即使在将抑郁和焦虑症状作为协变量处理时，PD 组的反刍水平也最低。BPD 组的反刍水平高于 MDD 组。
反刍反应增强不仅在 MDD 患者中存在，在 BPD 和 GAD/OCD 患者中也存在，这可能表明存在无效的思维控制。
