BACKGROUND Fibromyalgia (FM) is a chronic pain syndrome that is accompanied by notable psychological distress. However, little research has been done on how the psychopathological profile of FM patients may influence their functional status. METHOD Using the Symptom Checklist-90-Revised the study examined the psychopathological dimensions of 181 women with FM, and the role of psychopathology as a moderator of the relationship between physical symptoms and impairment of functioning. RESULTS FM patients exhibited T-scores above the cutoff point ≥60) in all dimensions, and 76.2% were identified as "clinical cases". Somatization was a significant predictor of pain intensity, somatization and obsession-compulsion contributed significantly to predicting poor sleep quality, while somatization, depression and anxiety were significant predictors of impairment. Psychopathology was a statistically significant moderator that increased the impact of poor sleep quality on impairment. CONCLUSIONS The dysfunctional psychological style is key in the impairment associated with FM. The evaluation of psychopathological profiles can allow the early identification of the patients who are most vulnerable to impaired functioning due to the presence of possible psychopathology, as well facilitating therapeutic adaptations.

心理病理学作为纤维肌痛患者身体症状与障碍之间关系的调节者。

背景技术纤维肌痛（FM）是一种伴随着明显的心理困扰的慢性疼痛综合症。但是，关于FM患者的心理病理特征如何影响其功能状态的研究很少。方法使用“症状清单-90-修订版”（Symptom Checklist-90-Revised），该研究检查了181名FM女性的心理病理学维度，以及心理病理学作为生理症状与功能障碍之间关系的调节者的作用。结果FM患者在所有维度上的T分数均高于临界点（≥60），其中76.2％被确定为“临床病例”。躯体化是疼痛强度的重要预测指标，躯体化和强迫强迫显着预测了不良的睡眠质量，而躯体化，抑郁和焦虑是损伤的重要预测指标。心理病理学是统计学上显着的调节剂，可增加不良睡眠质量对功能障碍的影响。结论功能失调的心理风格是与FM相关的损伤的关键。对心理病理学特征的评估可以使由于可能的心理病理学的存在而最容易受到功能受损的患者的早期识别，以及促进治疗适应性。
