THE ITALIAN VERSION OF THE INTERPERSONAL SEXUAL OBJECTIFICATION SCALE-PERPETRATION VERSION (ISOS-P): ADAPTATION AND PSYCHOMETRIC PROPERTIES OF A TOOL MEASURING SEXUAL OBJECTIFICATION.

The current study assesses the psychometric properties and the adaptation to the Italian context of the Interpersonal Sexual Objectification Scale-Perpetration Version (ISOS-P; Gervais et al., 2018), a tool to measure sexual objectification perpetration among women and men. A pilot study involving a sample of 904 Italian university students and later a study with a national sample of 2198 Italian citizens were conducted. Confirmatory factor analysis was performed to verify the bifactor structure of the scale. Convergent validity and invariance across gender were also tested. The results show good reliability and convergent validity of the scale. Furthermore, a partial metric invariance between males and females was found. The Italian adaptation of the ISOS-P presents appropriate psychometric properties and therefore can be applied to the Italian context. Some limitations and recommendations for future studies are discussed. [ABSTRACT FROM AUTHOR]
