Psychometric properties of sexual function questionnaire: evaluation of an Iranian sample

Female sexual dysfunction (FSD) is a real problem that affects 25-63% of women. There isno valid Persian version of sexual function questionnaire (FSQ).

The aim of this study was to test the reliability and validity of Persian version of sexualfunction questionnaire.

In this cross-sectional study, 547 women were questioned by Persian version ofSFQ. Factor analysis produced five domains of female sexual function. Internal consistency, test-retestreliability, and discriminant validity were calculated.

Five-factor structure accounted for 63% of the variance. Arousal-orgasm domain was as sameas arousal-sensation, arousal-lubrication, and orgasm domains of the original version. Enjoyment-desiredomain was similar to enjoyment and desire domains except one question. Pain and partner domains wereconsistent with original domains. Internal consistency, test-retest reliability, and discriminant validitywere reasonable in Persian version of SFQ.

Persian version of SFQ is almost valuable and reliable to use for Iranian population withexception of one question. Results of the omitted question from enjoyment domain should interpretseparately as unusual sex domain.
