Psychometric Properties of the Spanish Version of the Sexual Inhibition/Sexual Excitation Scales for Men.

The dual control model (DCM) postulates the involvement of relatively independent inhibitory and excitatory systems, which together provide a "double control" over sexual response and associated behavior (Janssen & Bancroft, 2007). Based on this model, the Sexual Inhibition and Sexual Excitation Scales assess the propensity for sexual excitation and sexual inhibition. This research focused on analyzing some psychometric properties of this questionnaire and developing a Spanish version in men. The sample consisted of 823 heterosexual men of ages ranging from 18 to 74 years. Confirmatory factor analysis generated a version of the scale that consisted of 34 items (11 items with the worst factor loadings were eliminated) distributed in four factors (one sexual excitation factor and three sexual inhibition factors). This is consistent with the DCM of sexual response. The four factors demonstrated good reliability coefficients except for sexual inhibition due to the threat of performance consequences, which was found to have a low internal consistency. Consequently, this is something that will be addressed in future studies. The four factors were found to have good test-retest reliability. The measures of the Sexual Inhibition and Sexual Excitation Scales had good validity properties and a coherent relationship with sexual sensation seeking and erotophilia.
