Objective: To evaluate the effect of PREVIOGEN in preventing gender violence among nursing students. Methodology: Quantitative study with a quasi-experimental test-retest design with a single group.

The topics are based on a combination of pedagogical approaches that include social, cultural and learning theories. These address gender perspectives in relation to equality, social justice, respect for diversity and the promotion of human rights, for 20 hours. Pre- and post-intervention questionnaires were applied to assess perceptions, attitudes and knowledge about gender violence. Data were analyzed with SPSS-26, using descriptive statistics and nonparametric tests. Cohen's d was used to analyze the effect size. Results: The findings show notable improvements in perceptions, attitudes, and knowledge after the educational intervention, indicating a large-scale positive effect in the fight against gender violence. Conclusions: The PREVIOGEN educational intervention was highly effective in improving perceptions, attitudes, and knowledge about the prevention of gender violence among nursing university students.
