The goals of this study were to investigate whether there was a dominant temperament type, and to assess the effect of temperament, pain catastrophizing, and anxiety sensitivity on pain severity, in female patients diagnosed with chronic pelvic pain (CPP) compared with healthy controls.
This cross-sectional study involved 51 patients 18 to 65 years of age who were diagnosed with CPP without a history of psychiatric treatment and 97 healthy volunteer women with sociodemographic characteristics similar to those of the study group. A sociodemographic form prepared by the researchers, the Anxiety Sensitivity Index, the Pain Catastrophizing Scale, a temperament scale (Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-Autoquestionnaire), and a visual analog pain scale (VAS) were completed. The results were compared between the patient and control groups. Multiple regression analyses were performed to examine the predictive effects of temperament characteristics, pain catastrophizing, and anxiety sensitivity on pain severity.
Scores on the Pain Catastrophizing Scale and the VAS were statistically significantly higher in the CPP group ( P <0.001). The frequency of depressive, cyclothymic, and irritable temperaments was found to be significantly higher in the CPP group (CPP: 7.78±3.32 vs. controls: 6.54±3.19; P =0.027; CPP:10.61±4.41 vs. controls: 8.82±4.21; P =0.017; CPP: 5.22±4.29 vs. controls: 3.75±3.41; P =0.025). According to the model established by temperament traits, anxiety sensitivity, and pain catastrophizing level, pain catastrophizing level explained 11.6% of the variance in pain severity. A 1-unit change in the score for pain catastrophizing level caused a 0.278-point change in the VAS total score ( P <0.01).
Cyclothymic, depressive, and irritable temperament types that increase the risk of affective disease are more common in patients with CPP. The level of pain catastrophizing in patients with CPP affects their perception of the severity of the pain.
本研究旨在探讨女性慢性盆腔痛（CPP）患者是否存在主导气质类型，并评估气质、疼痛灾难化和焦虑敏感性对疼痛严重程度的影响。
本横断面研究纳入了 51 名年龄在 18 至 65 岁之间、未经精神科治疗的 CPP 患者和 97 名具有与研究组相似社会人口学特征的健康志愿者女性。研究人员编制了一份社会人口学表格、焦虑敏感指数、疼痛灾难化量表、气质量表（孟菲斯、比萨、巴黎和圣地亚哥自动问卷）和视觉模拟疼痛量表（VAS），并完成了这些量表。比较了患者组和对照组的结果。进行多元回归分析，以检查气质特征、疼痛灾难化和焦虑敏感性对疼痛严重程度的预测作用。
CPP 组的疼痛灾难化量表和 VAS 评分均显著升高（P<0.001）。CPP 组抑郁、环性和易激惹气质的频率明显更高（CPP：7.78±3.32 与对照组：6.54±3.19；P=0.027；CPP：10.61±4.41 与对照组：8.82±4.21；P=0.017；CPP：5.22±4.29 与对照组：3.75±3.41；P=0.025）。根据气质特征、焦虑敏感性和疼痛灾难化水平建立的模型，疼痛灾难化水平解释了疼痛严重程度变异的 11.6%。疼痛灾难化水平得分增加 1 个单位，VAS 总分增加 0.278 分（P<0.01）。
增加情感疾病风险的环性、抑郁和易激惹气质类型在 CPP 患者中更为常见。CPP 患者的疼痛灾难化水平影响其对疼痛严重程度的感知。
