Abstract
Background: 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.
Objective: 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.
Methods: 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.
Results: 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).
Conclusion: 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.
期刊介绍：
The Journal of Reproductive and Infant Psychology reports and reviews outstanding research on psychological, behavioural, medical and social aspects of human reproduction, pregnancy and infancy. Medical topics focus on obstetrics and gynaecology, paediatrics and psychiatry. The growing work in relevant aspects of medical communication and medical sociology are also covered.
