It is essential to have a validated instrument to diagnose and quantify FSD in this population accurately. Objective: To validate the Female Sexual Function Index (FSFI). Method: The FSFI was applied to 272 sexually active Mexican women with recent diagnosis of breast cancer who had not initiated systemic cancer treatment. Results: The FSFI six-factor model is valid by confirmatory factor analysis, and the inventory and its factors have adequate internal consistency reliability. Conclusions: This study provides enough evidence about the reliability and factor structure of the FSFI questionnaire in the context of breast cancer clinical practice in Mexico.
