Infertility can have a considerable effect on a person's marital satisfaction. The Quality of Marriage Index (QMI) is a self-report inventory to measure global perceptions of marital satisfaction. The current study examined the reliability and validity of the Persian language version of QMI in a sample of infertile patients.
The mean QMI total score was 36.54 ± 6.87. The internal consistency of the scale was good, with a Cronbach's alpha of 0.922. All inter-item correlations and item-total correlations were also in acceptable range. The confirmatory factor analysis results provided evidence for unidimensionality of the scale (χ/df = 3.10; GFI = 0.97; CFI = 0.99; NFI = 0.99; RMSEA = 0.091 and SRMR = 0.020). The convergent validity of the QMI was demonstrated via significant correlations with measures of the Relationship Assessment Scale, Kansas Marital Satisfaction Scale, and Couples Satisfaction Index-4 Item. These correlations also tended to be larger than correlations with measures of Hospital Anxiety and Depression Scale and Perceived Stress Scale-4 Item. Among demographic/fertility variables, only infertility duration was negatively correlated to QMI scores. In sum, the QMI is a reliable and valid brief inventory for measuring overall marital satisfaction in infertile patients. Trial registration This was a cross-sectional study (NOT clinical trial); thus, the trail registration number is not required for the present study.
不孕症会对个人的婚姻满意度产生相当大的影响。婚姻质量指数（QMI）是一种自我报告量表，用于衡量对婚姻满意度的总体认知。本研究在一组不孕患者样本中检验了波斯语版QMI的信度和效度。
QMI总分的平均值为36.54±6.87。该量表的内部一致性良好，克朗巴哈系数为0.922。所有项目间相关性和项目与总分的相关性也在可接受范围内。验证性因素分析结果为该量表的单维度性提供了证据（χ/df = 3.10；GFI = 0.97；CFI = 0.99；NFI = 0.99；RMSEA = 0.091，SRMR = 0.020）。QMI的收敛效度通过与关系评估量表、堪萨斯婚姻满意度量表和夫妻满意度指数4项量表的测量结果显著相关得以证明。这些相关性也往往大于与医院焦虑抑郁量表和感知压力量表4项量表测量结果的相关性。在人口统计学/生育变量中，只有不孕持续时间与QMI得分呈负相关。总之，QMI是一种可靠且有效的简短量表，用于测量不孕患者的总体婚姻满意度。试验注册这是一项横断面研究（非临床试验）；因此，本研究不需要试验注册号。
