How Does Sexual Subjectivity Vary on the Basis of Gender and Sexual Orientation? Validation of the Short Sexual Subjectivity Inventory (SSSI-11) in Cisgender, Heterosexual and Sexual and Gender Minority Adolescents.

ABSTRACT

Through sexual exploration, adolescents learn that they are sexual beings with choices, desires, and are deserving of pleasure, which corresponds to sexual subjectivity. However, the two measures of this construct (i.e., Female Sexual Subjectivity Inventory and Male Sexual Subjectivity Inventory) have not been validated with younger adolescents and have different items for boys and girls (with no scale available for gender diverse individuals), limiting gender comparisons. This study examined (1) the factor structure of the adapted Short Sexual Subjectivity Inventory-11 items (SSSI-11) in a large sample of young cisgender, heterosexual and sexual and gender minority adolescents, (2) measurement invariance across language (English and French), gender, and sexual orientation, (3) validity with sexuality-related outcomes, and (4) one-year temporal stability. Results of a confirmatory factor analysis among 2001 adolescents (Mage = 15.5 years, SD = 0.60) revealed a multidimensional factor structure. The SSSI-11, in both English and French, showed adequate reliability and one-year temporal stability, and was invariant across genders, sexual orientations, and languages. Girls had lower scores on the entitlement to self-pleasure and self-efficacy in achieving pleasure factors, and higher scores on the entitlement to pleasure from a partner factor. No significant differences were observed on the basis of language or between heterosexual and sexual minority adolescents. The SSSI-11 correlated positively with sexuality-related variables. Findings support the strong psychometric properties of the SSSI-11, rendering it of considerable use in clinical, education, and research applications.
