Measurement Invariance of the Sexual Assault Script Scale (SASS): An Examination Among Hispanic and Non-Hispanic White College Women

Abstract

Rates of sexual victimization have remained steady over several decades, and preventative interventions to reduce men’s sexually aggressive behavior have been largely ineffective. As such, research has endeavored to find novel approaches to identify women at increased risk for sexual victimization. Sexual assault scripts, or “cognitive models” that women adhere to that guide their beliefs about sexual assault are posited to influence their victimization risk. Prior studies on sexual assault scripts primarily have been qualitative in nature; however, recent work yielded a 27-item measure of putative risk for sexual victimization called the Sexual Assault Script Scale (SASS). The SASS has four subscales called Stereotypical Assault Scripts, Acquaintance Assault Scripts, Assault Resistance Scripts, and Date/Friend Assault Scripts, which were found in prior work to be internally consistent and associated with putative risk factors for sexual victimization. The focus of the current study was to test the measurement invariance of the SASS among Hispanic and non-Hispanic White college women who were recruited in the prior study. Four hundred sixty-nine (N = 469) Hispanic and 415 non-Hispanic White US undergraduate heterosexual or bisexual women from a Southwestern university in the United States completed the SASS. Confirmatory factor analysis (CFA) replicated the prior four-factor model with an acceptable fit to the data, and tests of measurement invariance revealed the SASS to be invariant across Hispanic and non-Hispanic White college women, suggesting that the SASS is measuring a similar construct in these groups.
