Sexual violence is a persistent, underreported threat to the well-being of women and girls worldwide. In Vietnam, as elsewhere, myths and misconceptions around rape and other forms of sexual violence present a major barrier to reporting and prevention. Based on qualitative research from a parent study aimed at reducing sexual violence perpetration at universities in Vietnam, we sought to characterize commonly held myths among university students that may contribute to the perpetration and justification of such behaviors. Our analysis drew on focus group discussions with men ( n = 69) and semi-structured interviews with men ( n = 12) and women ( n = 9) recruited from two universities in Hanoi. Conducted in April and May of 2018, interviews covered topics including gender norms, dating relationships, consent, and sexual violence, whereas focus groups conducted in October 2018 were designed to assess reactions to an existing sexual violence prevention program. Thematic analysis of interview and focus group transcripts revealed that myths and misconceptions about sexual violence persist among university-aged men and women. Chief among these were that rape results mainly from men’s uncontrollable desire, that victims provoke rape by their “reckless” behavior, such as drinking or dressing provocatively, that “real” rape is characterized by physical force from the perpetrator and “fierce resistance” on the part of the victim, and that rape occurs only under a narrow set of circumstances. Although men and women endorsed most myths equally, justification of rape through victim blaming featured much less in women’s narratives than in men’s. Myths concerning false rape allegations, observed in Western populations, were not considered relevant to Vietnamese students. Findings informed the development of a contextualized rape myths acceptance scale for testing and use in Vietnam. A nuanced understanding of salient rape myths among male and female students may also inform university-based efforts to prevent sexual violence.
