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.

精神病理学作为纤维肌痛患者身体症状与损伤之间关系的调节剂。

背景纤维肌痛（FM）是一种慢性疼痛综合征，伴随着显着的心理困扰。然而，关于 FM 患者的精神病理学特征如何影响他们的功能状态的研究很少。方法 使用症状清单 - 90 - 修订本研究检查了 181 名患有 FM 的女性的精神病理学维度，以及精神病理学作为身体症状和功能障碍之间关系的调节器的作用。结果 FM 患者在所有维度上的 T 值均高于截止点≥60)，76.2% 被确定为“临床病例”。躯体化是疼痛强度的重要预测因子，躯体化和强迫症对预测不良睡眠质量有显着影响，而躯体化、抑郁和焦虑是损害的重要预测因素。精神病理学是一个具有统计学意义的调节因素，它增加了睡眠质量差对障碍的影响。结论 功能失调的心理风格是与 FM 相关的损伤的关键。精神病理学概况的评估可以允许早期识别由于可能的精神病理学的存在而最容易受到功能损害的患者，并促进治疗适应。
