Resumen

Introduction: Infertility is a stressful experience that significantly impacts quality of life. Objective: To perform the linguistic adaptation and analyze the psychometric properties of the 27-item short version of the Fertility Problem Inventory (FPI-SF27) in a Peruvian population. Methods: An instrumental, cross-sectional study was conducted. The sample consisted of 350 patients (175 men and 175 women) aged 18 years or older, treated in the assisted reproduction program of the Instituto Nacional Materno Perinatal (INMP). After translation and expert validation, an exploratory factor analysis (n = 175) was conducted, from which an optimized 20-item model was proposed. Subsequently, a confirmatory factor analysis (n = 175) was performed to compare the original version with the optimized model. First- and second-order models, measurement invariance by sex, and convergent validity were analyzed. Results: The second-order model with 20 items and four factors showed superior fit (CFI = 0.974; TLI = 0.967; SRMR = 0.065; RMSEA = 0.070, 95% CI: 0.054–0.088) and adequate reliability ( ω = 0.73 - 0.82 ). Strong measurement invariance by sex was observed ( ΔCFI < 0.002 ), along with convergent validity through significant correlations with anxiety (rho = 0.251), depression (rho = 0.255), and some dimensions of dyadic adjustment (rho = -0.144 to -0.160). Conclusion: The Spanish adaptation of the FPI-SF, consisting of 20 items and four factors, demonstrates adequate psychometric properties for use in the Peruvian population.
