The purpose of the present research was to develop a brief self-report index of male sexual functioning, which could be comparable in form and in content to the Brief Index of Sexual Functioning for Women (BISF-W). The study also presented an evaluation of the psychometric properties of the resulting measure, the Brief Index of Sexual Functioning for Men (BISF-M). The sample was made up of 190 Italian men. An Exploratory Factorial Analysis (EFA) was performed with the method of principal components and VARIMAX rotation. Internal consistency was calculated by means of Cronbach alpha coefficients for each factor. EFA on men’s data yielded 4 factors: Sexuality of the couple, Self-eroticism, Dissatisfaction, Anal sexuality, confirming the same factor structure of BISF-W, even if with some item-level gender variations. Internal consistency was also demonstrated. The BISF-W and the BISF-M are useful tests for evaluating the sexual function of Italian couples.
