Both the diagnosis and the process of undergoing fertility treatment have a considerable negative effect on a person's quality of life (QoL). The evaluation of this effect is essential to offer comprehensive and high-quality care. The FertiQoL questionnaire is the most widely used instrument to evaluate QoL in people with fertility issues.
This study is aimed at examining the dimensionality, validity and reliability of the Spanish version of the FertiQoL questionnaire in a sample of Spanish heterosexual couples undergoing fertility treatment.
FertiQoL was administered to 500 people (50.2% women; 49.8% men; average age 36.1 years) recruited from a public Assisted Reproduction Unit in Spain. In this cross-sectional study, Confirmatory Factor Analysis (CFA) was used to analyse the dimensionality, validity and reliability of FertiQoL. Discriminant and convergent validity were assessed using the Average Variance Extracted (AVE), and model reliability was shown by Composite Reliability (CR) and Cronbach's alpha.
CFA's results support the 6-factor solution of the original FertiQoL (RMSEA and SRMR <0.09; CFI and TLI >0.9). However, several items had to be eliminated due to their low factorial weights - in particular, items Q4, Q5, Q6, Q11, Q14, Q15 and Q21. Moreover, FertiQoL showed good reliability (CR >0.7) and validity (AVE >0.5).
The Spanish version of FertiQoL is a reliable and valid instrument in measuring QoL in heterosexual couples undergoing fertility treatment. The CFA confirms the original 6-factors model but indicates that by eliminating some items the psychometric properties could improve. However, further research is recommended to address some of the measurement issues.
无论是诊断还是接受生育治疗的过程，都会对人的生活质量（QoL）产生相当大的负面影响。评估这种影响对于提供全面和高质量的护理至关重要。FertiQoL 问卷是评估生育问题人群生活质量最常用的工具。
本研究旨在检验西班牙裔异性恋夫妇接受生育治疗时，FertiQoL 问卷的西班牙语版本的维度、有效性和可靠性。
从西班牙一家公立辅助生殖单位招募了 500 人（女性占 50.2%，男性占 49.8%；平均年龄 36.1 岁）接受 FertiQoL 调查。在这项横断面研究中，使用验证性因子分析（CFA）分析 FertiQoL 的维度、有效性和可靠性。使用平均方差提取（AVE）评估判别和收敛有效性，使用组合可靠性（CR）和 Cronbach's alpha 表示模型可靠性。
CFA 的结果支持 FertiQoL 的 6 因素解决方案（RMSEA 和 SRMR <0.09；CFI 和 TLI >0.9）。然而，由于因子权重较低，一些项目必须删除-特别是项目 Q4、Q5、Q6、Q11、Q14、Q15 和 Q21。此外，FertiQoL 显示出良好的可靠性（CR>0.7）和有效性（AVE >0.5）。
西班牙语版的 FertiQoL 是一种可靠和有效的工具，可用于测量接受生育治疗的异性恋夫妇的生活质量。CFA 证实了原始的 6 因素模型，但表明通过删除一些项目，心理测量特性可能会得到改善。然而，建议进行进一步的研究来解决一些测量问题。
