BACKGROUND
The 30-Item Endometriosis Health Profile (EHP-30) is a specific instrument measuring quality of life among women with endometriosis. Although the Swedish version of EHP-30 is widely used in research and clinical settings, it has not yet been evaluated psychometrically. Ensuring validity and reliability is of most importance when using translated instruments. Therefore, the aim of the study was to evaluate the psychometric properties of the Swedish version of the EHP-30.
METHODS
This study was conducted at a Swedish referral university hospital specializing in endometriosis. Data collection was performed in January 2013. The EHP-30 was sent to 369 randomly selected women with a laparoscopy-verified endometriosis diagnosis. The psychometric evaluation included evaluation of data completeness, score distributions, floor and ceiling effects, internal consistency, factor analysis and test-retest reliability.
RESULTS
Out of the 211 women with endometriosis who answered the questionnaire, 128 were native Swedish speakers who had experienced symptoms of endometriosis during the past 4 weeks, and were included in the psychometric evaluation. Data completeness was 99.5%. The highest median score was found in the Control and Powerlessness subscale, and lowest in Pain. Distributions towards ill health were found in all subscales except for the pain subscale, but there were no noteworthy floor or ceiling effects. Internal consistency was good (Cronbach's α 0.83-0.96). Factor analysis could roughly confirm three of the five subscales. The test-rest analysis showed good reliability. Scores were systematically lower during the second measurement.
CONCLUSIONS
We conclude that the Swedish version of EHP-30 is a valid and reliable instrument to measure health-related quality of life in women with endometriosis. It is understandable, acceptable and usable and can be recommended for use in clinical daily routines and for research purposes.
背景
30 项子宫内膜异位症健康状况量表（EHP-30）是一种专门用于测量子宫内膜异位症女性生活质量的特定工具。尽管瑞典语版的 EHP-30 在研究和临床环境中得到了广泛应用，但它尚未经过心理测量学评估。在使用翻译工具时，确保有效性和可靠性最为重要。因此，本研究的目的是评估瑞典语版 EHP-30 的心理测量特性。
方法
本研究在一家专门治疗子宫内膜异位症的瑞典转诊大学医院进行。数据收集于 2013 年 1 月进行。EHP-30 被发送给 369 名随机选择的腹腔镜确诊子宫内膜异位症的女性。心理测量评估包括评估数据完整性、分数分布、地板和天花板效应、内部一致性、因子分析和测试-重测可靠性。
结果
在回答问卷的 211 名子宫内膜异位症女性中，有 128 名是母语为瑞典语的女性，她们在过去 4 周内经历过子宫内膜异位症症状，被纳入心理测量评估。数据完整性为 99.5%。最高中位数得分出现在控制和无力感分量表中，最低的在疼痛分量表中。除了疼痛分量表外，所有分量表的健康状况分布都较差，但没有明显的地板或天花板效应。内部一致性良好（Cronbach's α 0.83-0.96）。因子分析大致可以确认五个分量表中的三个。测试-重测分析显示可靠性良好。第二次测量时得分系统降低。
结论
我们得出结论，瑞典语版 EHP-30 是一种有效的、可靠的工具，可以测量子宫内膜异位症女性的健康相关生活质量。它易于理解、可接受和使用，可推荐用于临床日常工作和研究目的。
