The aim was to analyze the psychometric properties of "Sexuality and the Mental Retardation Attitude Inventory" (SMRAI) in a sample of 144 psychology college students 2nd to the 9th, of a private university in Lima, of which 44 were males (30.6%) and 100 female (69.4%), aged between 17 and 43 years (average: 21.9). The confirmatory factor analysis conducted reveals that this test presents a two-factor structure with adequate fit indices. Furthermore, regarding the reliability of the construct using the coefficient "Rho", an indicator of 0.804. was obtained. We conclude that the SMRAI has appropriate psychometric properties to be implemented in studies oriented to know more facets about attitudes towards the sexuality of people with intellectual disabilities.
