Abstract: Introduction: Infertility is a stressful experience that affects patients' quality of life. Objective: This is an instrumental, psychometric, and cross-sectional study. A 27-item version of the Infertility Stress Inventory (FPI-SF) was adapted into Spanish and its psychometric properties were analyzed. Materials and Methods: The sample consisted of 350 participants (175 men and 175 women, respectively), patients over 18 years of age who were treated by the psychology service of the assisted reproduction program of the INMP. The Spanish adaptation of the FPI-SF was used, previously translated and validated using expert validity. Subsequently, the reliability and validity indicators of the original instrument were analyzed using confirmatory factor analysis and the 21-item model proposed through exploratory factor analysis. First- and second-order models were constructed, both with 4 factors. Invariance by sex and convergent validity were determined through the relationship with other variables. Results: The proposed 21-item second-order model showed better validity indicators (CFI=0.945; TLI=0.935; SRMR=0.070 and RMSEA=0.078, Inf:0.070 – Sup:0.085) and adequate reliability indicators (0.80-0.89). It presented a strong invariance according to sex (ΔCFI<0.002) and convergent validity by presenting significant correlation with the variables anxiety (rho=0.310), depression (rho=0.326) and the dyadic adjustment scale (rho=-0.128 and -0.243). Conclusion: The adaptation into Spanish of the infertility stress problems inventory FPI-SF, composed of 20 items and 4 factors, presents adequate psychometric properties for its application.
