Objective: The present research aimed to evaluate the psychometric properties of the Persian language version of the Female Sexual FunctionIndex (FSFI) among postmenopausal women.Material and Methods: This secondary analysis examined 402 healthy postmenopausal Iranian women presenting to healthcare centersacross Iran. The sampling method was convenience sampling. The translation of the FSFI and its cross-cultural adaptation were conducted underthe guidelines proposed by Beaton. The reliability (Cronbach’s alpha coefficient and test-rest reliability) and construct validity confirmatory factoranalysis) were assessed. Model fitting index [such as the root mean square error of approximation (RMSEA), the Goodness of Fit Index (GFI) andthe Comparative Fit Index (CFI)] was calculated.Results: The mean age of the study participants was 53.63±7.8 years. Test-retest reliability was high for both the entire scale (r=0.964; p
