BACKGROUND/AIMS: This study compared women suffering chronic pelvic pain (CPP) secondary to endometriosis (n = 30) with women experiencing CPP due to either myofascial abdominal/pelvic pain (n = 70) or pelvic adhesions (n = 38) to determine if there are specific psychological variables uniquely associated with endometriosis.
This is a cross-sectional study of 138 women drawn from a convenience sample of 192 consecutive women with CPP presenting for evaluation to a university hospital chronic pain clinic. Subjects were categorized into groups based on their CPP diagnosis. Each subject completed a battery of validated inventories assessing demographic status, pain experience and other pain-related symptoms, pain disability, frequency of depressive symptoms, level of affective distress, satisfaction with pain treatment and satisfaction with their marital relationship.
No differences were obtained across the three groups for any of the outcome measures. Effect size computation supported the absence of clinical differences across the groups for these measures.
These findings fail to support the presence of a unique psychological profile or disproportionate psychological disturbance for women with CPP due to endometriosis. These data illustrate the importance of considering control groups that include chronic pain when exploring psychological contributions to specific chronic pain conditions.
背景/目的：本研究比较了因子宫内膜异位症（n = 30）和因腹/盆腔肌肉筋膜疼痛（n = 70）或盆腔粘连（n = 38）导致慢性盆腔疼痛（CPP）的女性，以确定是否存在与子宫内膜异位症相关的特定心理变量。
这是一项横断面研究，共纳入了 138 名女性，这些女性是从 192 名连续就诊于大学医院慢性疼痛诊所的 CPP 女性中抽取的方便样本。根据 CPP 诊断对受试者进行分组。每位受试者完成了一系列经过验证的问卷，评估人口统计学状况、疼痛体验和其他与疼痛相关的症状、疼痛残疾、抑郁症状频率、情感困扰程度、疼痛治疗满意度和婚姻关系满意度。
三组之间在任何结果测量上均无差异。效应量计算支持这些测量在组间不存在临床差异。
这些发现不支持因子宫内膜异位症导致 CPP 的女性存在独特的心理特征或不成比例的心理障碍。这些数据说明了在探索特定慢性疼痛病症的心理贡献时，考虑包括慢性疼痛的对照组的重要性。
