绝经期特定生活质量（MENQOL）问卷是一种测量绝经后妇女健康相关生活质量的特定工具。到目前为止，中文版问卷还没有进行大样本的心理测量评估。本研究旨在评估中国绝经后妇女MENQOL中文版的效度和信度。采用方便抽样方法，从中国8个城市共招募了1137名有更年期症状的妇女和491名无更年期症状的妇女。通过描述性统计、效度和信度评估心理测量特性。通过内部一致性信度与Cronbach's α和子量表间相关来评估MENQOL各子量表的信度。项目域相关性，主成分分析（PCA）和验证性因子分析来确定结构效度。采用T检验比较绝经期有症状和无症状妇女之间的差异，并评估区分效度。计算MENQOL评分与Kupperman指数之间的Pearson相关系数，以评估标准相关效度。中国更年期症状女性最常见的症状是“记忆力差”（94.4%）、“感觉疲劳或疲惫”（93.8%）、“肌肉和关节疼痛”（89.4%）、“腰痛”（86.9%）、“体力下降”（86.6%）、“颈后或头部疼痛”（86.2%）、“睡眠困难”（83.6%）、“做事不如以前”（83.4%）、“感觉精力不足”（83.3%）、“性欲改变”（81%）、“潮热”（80.7%）等。“面部毛发增加”的症状很少见（9.9%）。血管舒缩领域，以及心理社会、生理和性领域显示出高可靠性（Cronbach’s α分别为0.84、0.87、0.89和0.86）。项目-领域相关分析表明，所有项目与自身领域的相关性强于与其他领域的相关性。在PCA中，在删除“面部毛发增加”项目后，血管舒缩、性和社会心理亚量表中的项目基本上在各自的领域上加载，身体亚量表中的项目分为两个因素。主成分分析显示，MENQOL中文版本的潜在结构与MENQOL原结构域几乎相同。验证性因子分析表明，问卷符合四域模型。MENQOL可以区分绝经期有症状妇女和无症状妇女，具有良好的区分效度。MENQOL评分与Kupperman指数之间存在显著相关，证实了标准相关效度。本研究表明，中文版MENQOL具有良好的心理测量性能，适用于测量除21项（面部毛发增加）外的中国绝经妇女健康相关生活质量。
The Menopause-Specific Quality-of-Life (MENQOL) questionnaire was developed as a specific tool to measure the health-related quality-of-life of postmenopausal women. Thus far, the Chinese version questionnaire has not been subjected to psychometric assessment with a large sample. This study aims to evaluate the validity and reliability of the Chinese version of the MENQOL specific to postmenopausal women in China. A total of 1,137 menopausal symptomatic and 491 menopausal asymptomatic women from eight cities in China were recruited using a convenience sampling method. Psychometric properties were evaluated by descriptive statistics, validity, and reliability. Reliability was assessed for each subscale of the MENQOL through internal consistency reliability with Cronbach's α and intersubscale correlations. Item-domain correlations, principal components analysis (PCA), and confirmatory factor analysis were performed to determine construct validity. t tests were used to compare the differences between the menopausal symptomatic and asymptomatic women and to evaluate the discriminate validity. Pearson correlation coefficients were calculated between MENQOL scores and the Kupperman index to assess criterion-related validity. The most common symptoms in Chinese menopausal symptomatic women were “experiencing poor memory” (94.4%), “feeling tired or worn out” (93.8%), “aching in muscle and joints” (89.4%), “low backache” (86.9%), “decrease in physical strength” (86.6%), “aches in back of neck or head” (86.2%), “difficulty sleeping” (83.6%), “accomplishing less than I used to” (83.4%), “feeling a lack of energy” (83.3%), “change in your sexual desire” (81%), and “hot flash” (80.7%) among others. The symptoms of “increased facial hair” were rarely seen (9.9%). The vasomotor domain, as well as psychosocial, physical, and sexual domains showed high reliability (Cronbach's α 0.84, 0.87, 0.89, and 0.86, respectively). Item-domain correlation analysis showed that all items correlated more strongly with their own domains than with other domains. In the PCA, after deleting the “increased facial hair” item, items in the vasomotor, sexual, and psychosocial subscales loaded on their respective domains by and large, and items in the physical subscale divided into two factors. The PCA revealed a latent structure of the Chinese version of MENQOL nearly identical to the original MENQOL domains. The confirmatory factor analysis demonstrated that the questionnaire fits well with a four-domain model. The MENQOL can discriminate between menopausal symptomatic women with asymptomatic women as it showed good discriminate validity. Criterion-related validity was confirmed by a significant correlation between MENQOL scores and the Kupperman index. This study showed that Chinese version of MENQOL has good psychometric properties and would be suitable to measure the health-related quality-of-life of Chinese menopausal women except for item 21 (increased facial hair).
