Resumen:
BACKGROUND: Health systems play a key role in the detection and management of gender-based violence. This study aimed to evaluate the effectiveness of a training program designed to enhance the knowledge, skills, and attitudes of emergency healthcare professionals in addressing gender-based violence. METHODOLOGY: A quasi-experimental pre-post study was conducted with 115 emergency health professionals from the Murcian Health Service. Participants completed a 10-hour online training program utilizing active learning methodologies, including guided reflection on didactic and dramatized problem-based videos. The Knowledge, Skills, and Attitudes on Gender-Based Violence Questionnaire (CCHA-VioGen) was administered before and after the training. RESULTS: Statistically significant improvements were observed in all three dimensions. Knowledge and skills showed medium effect sizes (d=2.07 and d=1.99, respectively), while attitude improved with small effect size (d=0.61). Participants rated the course highly in terms of learning consolidation and applicability, indicating that the course content was perceived as relevant and useful. The perceived need for further training was low, suggesting a strong sense of preparedness following the intervention. CONCLUSIONS: The training program is highly effective in enhancing healthcare professionals´ competencies in managing cases of gender-based violence. Short, online courses that incorporate innovative resources such as dramatized problem videos represent a feasible and impactful strategy for professional development, especially in setting with limited resources.
