Endometriosis Health Profile (EHP-5) is a valid instrument to measure health-related quality of life in endometriosis. This study was conducted to culturally adapt and validate the EHP-5 in Iran.
Using a standard "forward-backward' translation procedure, the English language version of the questionnaire was translated into Persian (Iranian language). Then a sample of 199 women aged 18-50 years completed the questionnaire. To test reliability the internal consistency was assessed by Cronbach's alpha coefficient. Validity was evaluated using known groups comparison.
The mean age of respondents was 31.4 (SD = 5.4) years. Reliability analysis showed satisfactory result (Cronbach's alpha coefficient = 0.71). The questionnaire discriminated well between sub-groups of women differing in infertility and premenstrual syndrome (PMS) in the expected direction.
This preliminary validation study of the Iranian version of the EHP-5 proved that it is an acceptable, reliable and valid measure of quality of life in endometriosis patients.
子宫内膜异位症健康状况量表（EHP-5）是一种评估子宫内膜异位症患者生活质量相关的有效工具。本研究旨在对其进行文化调适及验证，以评估其在伊朗的适用性。
采用标准的“前后翻译”程序，将问卷的英文版本翻译为波斯语（伊朗语）。然后，199 名年龄在 18-50 岁的女性完成了问卷。为了测试信度，采用 Cronbach's alpha 系数评估内部一致性。通过已知组别的比较评估效度。
应答者的平均年龄为 31.4（SD = 5.4）岁。信度分析显示出令人满意的结果（Cronbach's alpha 系数 = 0.71）。问卷在预期方向上很好地区分了在不孕和经前综合征（PMS）方面存在差异的女性亚组。
本研究初步验证了 EHP-5 伊朗版本的可接受性、可靠性和有效性，可用于评估子宫内膜异位症患者的生活质量。
