Summary	The Sexual Experiences Survey (SES) is a self-report instrument developed by Mary P. Koss and Cheryl J. Oros in 1982 to measure sexual aggression and victimization using behaviorally specific items rather than legal or stigmatizing labels. Instead of asking whether someone was 'raped', it asks about concrete acts and the tactics used to obtain them, ordering experiences along a severity continuum from unwanted sexual contact through verbal coercion to attempted and completed rape. It exists in matched victimization (SES-V) and perpetration (SES-P) versions, with widely used revised short forms (SES-SFV and SES-SFP) released after the 2007 collaborative revision.	The Ambivalent Sexism Inventory (ASI) is a 22-item self-report measure developed by Peter Glick and Susan T. Fiske in 1996 to assess both hostile and benevolent sexism toward women. The scale captures the dual nature of sexism: overtly antagonistic attitudes and paternalistic but ultimately restrictive attitudes that present themselves as protective. It has become widely used in gender studies and organizational research.
