Fibromyalgia (FM) is characterized by widespread pain and high levels of sleep disturbance, fatigue, and altered cognition. Psychological stress can modulate these features. In this study, we examined the thinking style of rumination in women with FM to assess the effect of rumination on stress levels and other psychological variables in FM.
Ninety-eight women with FM completed questionnaires to assess levels of rumination, stress, anxiety, depression, optimism, control, and coping. T-tests and bivariate (Pearson) analysis was performed to assess relationships between rumination and other psychological factors.
We found that those with higher levels of rumination had increased the use of negative coping techniques (p<0.001), higher anxiety (p<0.001), depression (p<0.001), and poor sleep levels (p<0.05). Higher rumination correlated with lower optimism (p<0.001) and control (Mastery) (p<0.001). High rumination correlated strongest with stress (p<0.001). Rumination predicted 26% of variance for perceived stress.
Rumination influenced several psychological processes deemed important in FM and was an important contributor to stress in FM. Specific interventions targeting rumination in FM may improve FM symptoms and outcomes.
纤维肌痛（FM）的特征是广泛疼痛、高水平的睡眠障碍、疲劳和认知改变。心理压力可调节这些特征。在本研究中，我们研究了FM女性的反刍思维方式，以评估反刍对FM患者压力水平和其他心理变量的影响。
98名FM女性完成了问卷调查，以评估反刍、压力、焦虑、抑郁、乐观、控制和应对水平。进行t检验和双变量（Pearson）分析，以评估反刍与其他心理因素之间的关系。
我们发现，反刍水平较高的人增加了消极应对技巧的使用（p<0.001），焦虑水平更高（p<0.001）、抑郁水平更高（p<0.001），睡眠质量较差（p<0.05）。较高的反刍与较低的乐观度（p<0.001）和控制感（掌控感）（p<0.001）相关。高反刍与压力的相关性最强（p<0.001）。反刍预测了感知压力26%的方差。
反刍影响了FM中一些被认为重要的心理过程，并且是FM压力的重要促成因素。针对FM中反刍的特定干预措施可能会改善FM症状和结局。
