Abstract

Purpose

Our main objective is to evaluate the psychometric properties of the Spanish version of the EHP-30 questionnaire. The secondary aim is to evaluate the differences in the scores of the core EHP-30 scales between patients with either surgical treatment or conservative management of endometriosis.

Methods

Cross-sectional study conducted into a tertiary hospital endometriosis reference unit. All patients (n = 223) pre-surgically completed the core EHP-30 questionnaire, the EQ-5D questionnaire (n = 184) and a visual analogue scale (n = 210) for endometriosis-related pain. Demographical and clinical data were recorded.

Results

Psychometric characteristics of the Spanish core EHP-30 questionnaire were investigated. Statistical analyses confirmed the five-structure factor, a high degree of internal consistency and of item-total correlation for all the assessed items. Convergent validity between EQ-5D and EHP-30 items and between VAS and EHP-30 subscale pain was observed. Additionally, patients with surgical management rendered significantly higher scores in the core EHP-30 subscales “pain” and “control and powerlessness”.

Conclusions

We present the reliability, validity and acceptability of the Spanish core EHP-30 questionnaire, providing clinicians and researchers with an improved tool to assess the endometriosis-related quality of life. Additionally, we show that patients subsidiaries of surgical treatment for endometriosis present with higher pain and powerlessness than those with conservative management.

改善对子宫内膜异位症生活质量的评估：评估西班牙版子宫内膜异位症健康概况 30

摘要

目的

我们的主要目标是评估西班牙版 EHP-30 问卷的心理测量特性。次要目的是评估子宫内膜异位症手术治疗或保守治疗患者之间核心 EHP-30 量表评分的差异。

方法

在三级医院子宫内膜异位症参考单位进行的横断面研究。所有患者 ( n  = 223) 术前完成了核心 EHP-30 问卷、EQ-5D 问卷 ( n  = 184) 和子宫内膜异位症相关疼痛的视觉模拟评分 ( n  = 210)。记录人口统计学和临床​​数据。

结果

对西班牙核心 EHP-30 问卷的心理测量特征进行了调查。统计分析证实了所有评估项目的五结构因素、高度的内部一致性和项目-总相关性。观察到 EQ-5D 和 EHP-30 项目之间以及 VAS 和 EHP-30 分量表疼痛之间的收敛效度。此外，接受手术治疗的患者在核心 EHP-30 子量表“疼痛”和“控制力和无力感”中的得分明显更高。

结论

我们介绍了西班牙核心 EHP-30 问卷的可靠性、有效性和可接受性，为临床医生和研究人员提供了一种改进的工具来评估子宫内膜异位症相关的生活质量。此外，我们表明，子宫内膜异位症手术治疗的附属患者比保守治疗的患者表现出更高的疼痛和无力感。
