Abstract

Objective: Sexual desire is a psychological state that prompts individuals to engage in sexual activity. Although interest about this topic is constantly increasing, there are no validated instruments to measure sexual desire in Italy, making scientific studies difficult. This paper aims to provide a contribution to validation of the Sexual Desire Inventory-2 (SDI-2) for the Italian population, investigating factorial structure, invariance, reliability and validity.

Method: The sample was composed of 389 Italian participants from a nonclinical population. The thirteen-item SDI-2 and the Barratt Impulsiveness Scale (BIS-11) for measuring impulsiveness were administered.

Results: The results supported two dimensions, i.e. dyadic and solitary desire, and partially measurement invariance across gender. Furthermore, good validity and reliability indicators have been gained.

Conclusions: the Italian version of the SDI-2 supports good psychometrics properties. It may be considered a valid and reliable measure for assessing dyadic and solitary sexual desire. Therefore, the present inventory may be used, in the research and clinical field, as an innovative instrument in order to investigate sexual desire and its relationship with clinical disorders.

Keywords: Italian validation; factor analysis; psychometrics properties; sexual desire; structural equation modelling.
