Sexual violence with its enormous negative consequences has become an epidemic most especially among the young populations. An effective danger-proof reporting system is necessary for curbing this menace including use of the internal whistleblowing mechanism. The study employed a concurrent (parallel) mixed method descriptive design for explaining the sexual violence experiences of university students, the intention of staff and students to blow the whistle, and their preferred whistleblowing strategies. A total of 167 students and 42 members of staff (69% males and 31% females, respectively) were randomly selected from four academic departments (50%) of a university of technology in Southwest Nigeria. An adapted questionnaire containing three vignettes on sexual violence and a focus group discussion guide were used for data collection. We discovered that 16.1% of the students reported to have experienced sexual harassment, 12.3% had attempted rape, and 2.6% had experienced rape. Tribe ( Likelihood-Ratio, LR = 11.16; p = .004) and sex (χ2 = 12.65; p = .001) were strongly associated with sexual violence experiences. Also, 50% staff and 47% students had high intention. Regression analysis showed that industrial and production engineering students will be 2.8 times more likely to have intention to internally blow the whistle more than other students ( p = .03; 95% CI [1.1, 6.97]). Female staff had 5.73 odds of intention more than male staff ( p = .05; [1.02, 32.1]). Also, we observed that senior staff will 31% less likely blow the whistle than the junior staff (Adjusted Odd Ratio, AOR = 0.04; [0.00, 0.98]; p = .05). In our qualitative findings, courage was mentioned as a factor necessary for blowing the whistle while anonymous reporting was emphasized for successful whistleblowing. However, the students preferred external whistleblowing. The study has implication for the establishment of sexual violence internal whistleblowing reporting system in higher education institutions.
