Infertility and its treatment can have a considerable effect on a person's quality of life (QoL). The Fertility QoL (FertiQoL) questionnaire is currently the most frequently used instrument to measure QoL in people with fertility problems. This study aims to examine the reliability and validity of the FertiQoL in infertile Iranian women.
This cross-sectional study included 155 women with fertility problems in a referral fertility clinic in Tehran, Iran from January to March 2014. A battery of instruments was used: FertiQoL, Satisfaction with Life Scale (SWLS), Hospital Anxiety and Depression Scale (HADS), and a demographic questionnaire. Construct validity of the scale was evaluated using confirmatory factor analysis (CFA). We assessed internal consistency with Cronbach's alpha and convergent validity was examined by correlating the FertiQoL with SWLS and HADS.
The results of the CFA generally supported the four-factor model of Core FertiQoL and two-factor model of Treatment FertiQoL. Both FertiQoL modules and their subscales revealed acceptable internal consistency that ranged from 0.643 to 0.911. However, the FertiQoL might be improved if Q15 and T2 items were removed from the scale. These items had low loadings on the Relational and Environment factors which decreased their internal consistency. The FertiQoL and their subscales significantly correlated with both SWLS and HADS, which confirmed convergent validity.
The Persian version of the FertiQoL is a valid, reliable instrument to measure QoL in infertile women and seems to perform as well as the original English Version.
不孕症及其治疗会对一个人的生活质量（QoL）产生相当大的影响。生育生活质量（FertiQoL）问卷是目前用于测量有生育问题人群生活质量的最常用工具。本研究旨在检验FertiQoL在伊朗不孕女性中的信度和效度。
这项横断面研究纳入了2014年1月至3月在伊朗德黑兰一家转诊生育诊所的155名有生育问题的女性。使用了一系列工具：FertiQoL、生活满意度量表（SWLS）、医院焦虑抑郁量表（HADS）以及一份人口统计学问卷。量表的结构效度通过验证性因子分析（CFA）进行评估。我们使用Cronbach's alpha评估内部一致性，并通过将FertiQoL与SWLS和HADS进行相关性分析来检验收敛效度。
CFA结果总体上支持核心FertiQoL的四因素模型和治疗FertiQoL的两因素模型。FertiQoL的两个模块及其子量表均显示出可接受的内部一致性，范围在0.643至0.911之间。然而，如果从量表中删除Q15和T2项目，FertiQoL可能会得到改善。这些项目在关系和环境因子上的载荷较低，降低了它们的内部一致性。FertiQoL及其子量表与SWLS和HADS均显著相关，证实了收敛效度。
FertiQoL的波斯语版本是一种有效、可靠的工具，可用于测量不孕女性的生活质量，其表现似乎与原始英语版本相当。
