The objective of the study was to determine to what extent personality and attitudes towards machismo predict sexual harassment in a sample of 470 university students in Chiclayo. The research is a predictive, cross-sectional, non-experimental research. The instruments applied were the Big Five Personality Inventory (BFI), the Attitudes towards Machismo Scale and the Sexual Harassment and Social Interaction with Sexual Content in the University Environment Scale (EASIS-U), which were virtualized through "google forms". The results indicate that all significance indices, statistical power and effect size are adequate. Therefore, in women, neuroticism and macho attitudes towards male chauvinism explain 12.5% of sextortion. And for men, extraversion, macho attitudes towards home management and sex role socialization explain 13.5% of verbal sexual harassment.
