Use of the Female Sexual Function Index in Women with Vulvar Intraepithelial Neoplasia

The present investigation extends the validation of the Female Sexual Function Index (FSFI; Rosen et al., 2000) to include women with vulvar excisions for vulvar intraepithelial neoplasia (VIN). No instrument previously has been validated in this population. We administered the instrument to 43 women (n = 43) with VIN treated with vulvar excision and age-matched healthy controls (n = 43). We found the FSFI to have high reliability and validity in the VIN excision population. Discriminant validity and internal consistency were within acceptable ranges. Using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ C-30; Agronson et al., 1993) and the FSFI in this population, we found a correlation between a related construct of quality of life and sexual function.
