Testing the Internal Consent Scale for Measurement Invariance Across Women and Men

AbstractThe Internal Consent Scale (ICS) was created to measure feelings associated with a person ’s willingness to engage in partnered sexual activity. Although previous studies using the ICS have assessed gender differences, evidence has not been provided to suggest that the ICS functions similarly for women and men. Using data from an online cross-sectional survey of adults (N =  874; 53.1% women), we subjected the 25-item ICS to tests of measurement invariance across gender. We found that only partial  measurement invariance was tenable, which indicated that direct comparisons across gender should be interpreted with caution when using the ICS. Therefore, we created a gender-invariant short form. In support of construct validity, we found that this 15-item ICS–Short Form demonstrated similar associations with measures of sexual consent communication as the full 25-item ICS. If researchers aim to compare women and men on internal sexual consent, we recommend using the 15-item ICS–Short Form. Cognitive interviews should be conducted to further understand how women and men might differ entially interpret ICS items.
