SILVA JUNIOR, Mauro Dias et al. Evidence of the Male Sexual Function Index (MSFI) for the Brazilian Context. Aval. psicol. [online]. 2023, vol.22, n.1, pp.103-110.  Epub May 03, 2024. ISSN 1677-0471.  https://doi.org/10.15689/ap.2023.2201.23399.11.

The Male Sexual Function Index (MSFI) is an instrument that assesses five domains of male sexual function: desire, arousal, erection, orgasm, and satisfaction. This study aimed to adapt and seek validity evidence for the MSFI for the Brazilian context. The participants comprised 449 men aged 18 to 65 years. The results showed an adequate fit of the data to the instrument’s five-factor model, according to the original version of the MSFI. Configural, metric, and scalar invariance for the MSFI was also found across heterosexual, bisexual, and gay participants. Correlations with other variables were also as expected, for example, a positive correlation between the factor desire from MSFI and the sexual excitation. The Brazilian version of the MSFI showed to be adequate to measure the construct in men of different sexual orientations.
