Prevalence of Unwanted Sexual Experiences and their Associations on University Students in the United States, United Kingdom and Ireland: A Systematic Review

Whilst prevalence rates of unwanted sexual experiences (USEs) and their association on Higher Education Institution students have been extensively researched for decades in the United States of America (US), there is a dearth of published studies on this topic in the United Kingdom (UK) and Ireland. The current study reviewed existing peer-reviewed and specific grey literature from these countries between 2000 and January 2023 on USEs (n = 48) to determine (1) prevalence rates, (2) most prevalent act, and (3) impacts of USEs on higher education students. It is evident from the included studies that prevalence rates of USE are wide ranging, with rates from 7% to 86%. However, findings were difficult to synthesise due to variations in definitions and measurements utilised. Students report both mental health and substance use following a USE. The review concludes by providing recommendations for future research, practice, and policy.
