The Endometriosis Health Profile-30 (EHP-30) is a disease-specific questionnaire to measure the health-related quality of life in patients with endometriosis. The aim of this study was to evaluate the validity and reliability of the Persian version of Endometriosis Health Profile (EHP-30) in women with endometriosis referring to three Gynecology Clinics in Tehran, Iran.
One hundred women (20 to 50 years old) with surgically confirmed endometriosis recruited from three outpatient Gynecology Clinics affiliated to the Iran University of Medical Sciences. All 100 patients were asked to complete EHP-30 questionnaire while referring to the Clinics. The findings were analyzed using descriptive statistics, internal reliability consistency, construct validity (using short form-36, which had already been validated in Iran), factor analysis (with principle component analysis method), and item total correlation to assess the validity and reliability of the questionnaire.
The internal consistency reliability of the questionnaire was high (Cronbach's α ranged between 0.80 and 0.93 for core, and 0.78 and 0.90 for modular parts). All items were loaded on their own factors except item 17 (feeling aggressive or violent) and item 18 (feeling unwell), which were loaded on pain and social support domains, respectively. Construct validity of EHP-30, established by using SF-36, indicates good correlations in several similar scales of these two questionnaires.
The findings of the study demonstrate that Persian version of EHP-30 is a valid and reliable measure to assess the quality of life in women with endometriosis.
子宫内膜异位症健康概况-30（EHP-30）是一种针对子宫内膜异位症患者健康相关生活质量的特定疾病调查问卷。本研究旨在评估在伊朗德黑兰三家妇科诊所就诊的子宫内膜异位症女性中，波斯语版子宫内膜异位症健康概况（EHP-30）的有效性和可靠性。
从伊朗医科大学附属的三家门诊妇科诊所招募了100名年龄在20至50岁之间、经手术确诊为子宫内膜异位症的女性。所有100名患者在前往诊所就诊时被要求完成EHP-30问卷。使用描述性统计、内部可靠性一致性、结构效度（使用已在伊朗验证的简短健康调查问卷-36）、因子分析（采用主成分分析法）以及项目与总分相关性来分析结果，以评估问卷的有效性和可靠性。
问卷的内部一致性可靠性较高（核心部分的Cronbach's α在0.80至0.93之间，模块部分在0.78至0.90之间）。除第17项（感觉有攻击性或暴力倾向）和第18项（感觉不适）外，所有项目均加载到各自的因子上，第17项和第18项分别加载到疼痛和社会支持领域。通过使用SF-36建立的EHP-30结构效度表明，这两份问卷在几个相似量表上具有良好的相关性。
该研究结果表明，波斯语版EHP-30是评估子宫内膜异位症女性生活质量的有效且可靠的工具。
