Quality of sexual life and satisfaction in female partners of men with ED: psychometric validation of the Index of Sexual Life (ISL) questionnaire

Effective treatments for erectile dysfunction (ED) are available, however, reestablishing erectile function does not necessarily reestablish a satisfying sexual relationship. To assess broader influences on treatment discontinuation than pure efficacy, we developed and psychometrically validated the Index of Sexual Life (ISL) to measure the impact of ED on female partners' sexuality. This 11-item instrument measures sexual life satisfaction, sexual drive and general life satisfaction. Good construct validity, criterion validity, and reproducibility were demonstrated. Female partners of men with ED report significantly lower levels of sexual satisfaction and sexual drive than those without ED. The ISL is successfully validated.
