Welcome to the FSFI Website 

Female Sexual Function Index


The FSFI is a brief questionnaire measure of sexual functioning in women.  It was developed for the specific purpose of assessing domains of sexual functioning (e.g. sexual arousal, orgasm, satisfaction, pain) in clinical trials.  It is not a measure of sexual experience, knowledge, attitudes, or interpersonal functioning in women.  It was not designed for use as a diagnostic instrument and should not be used as a substitute for a complete sex history in clinical evaluation.

The FSFI was validated in two groups of women, including subjects with sexual arousal disorder (determined by history) and age-matched controls.  The instrument sensitively and reliably differentiated these two groups on all domains of sexual functioning.  The FSFI may be useful for evaluation of treatment outcome in a clinical trial situation, but this remains to be demonstrated.

The psychometric validation of the FSFI was conducted by a group of investigators*, with funding from two corporate sponsors (Bayer AG and Zonagen, Inc.).  Target Health Inc. served as the CRO for the project.  Raymond Rosen, Ph.D., Professor of Psychiatry at Robert Wood Johnson Medical School, served as principal investigator for the study.  The study has been published in the Journal of Sex and Marital Therapy.
