Psychometric properties of Sexual Function Questionnaire: evaluation of an Iranian sample

Background: Female sexual dysfunction (FSD) is a real problem that affects 25-63% of women. There is no valid Persian version of sexual function questionnaire (FSQ). Objectives: The aim of this study was to test the reliability and validity of Persian version of sexual function questionnaire. Materials and Methods: In this cross-sectional study, 547 women were questioned by Persian version of SFQ. Factor analysis produced five domains of female sexual function. Internal consistency, test-retest reliability, and discriminant validity were calculated. Results: Five-factor structure accounted for 63% of the variance. Arousal-orgasm domain was as same as arousal-sensation, arousal-lubrication, and orgasm domains of the original version. Enjoyment-desire domain was similar to enjoyment and desire domains except one question. Pain and partner domains were consistent with original domains. Internal consistency, test-retest reliability, and discriminant validity were reasonable in Persian version of SFQ. Conclusion: Persian version of SFQ is almost valuable and reliable to use for Iranian population with exception of one question. Results of the omitted question from enjoyment domain should interpret separately as unusual sex domain.
