Impact of a Training Intervention on the Prevention of Aggressions in Nursing Students: A Pre–Post Study

Background: Violence against healthcare professionals constitutes a global and persistent problem, with significant consequences for professionals’ physical and mental health, organisational climate, and the quality of care provided to patients. Objective: To evaluate the impact of a training activity on the prevention and management of aggression in healthcare settings among fourth-year undergraduate nursing students. Materials and Methods: The study was conducted at the Nuestra Señora de Candelaria School of Nursing, University of La Laguna. An intervention study with a quasi-experimental design without a control group was conducted through the implementation of a training workshop. A pre- and post-intervention questionnaire was administered to a sample of 59 fourth-year nursing students. In addition, two questionnaires were distributed at the end of the session to assess satisfaction with the training received and students’ self-perceived acquisition of knowledge. This research complied with the TREND statement. Results: Descriptive analysis showed higher post-test scores than pre-test scores. The Wilcoxon test indicated a statistically significant difference between the pre-test and post-test scores. Mean knowledge scores increased from 3.16 to 7.58 following the intervention, with a statistically significant difference (p < 0.001) and a very large effect size (r = 0.87). Conclusions: The training workshop was associated with a significant immediate improvement in knowledge, high levels of satisfaction, and enhanced self-perceived learning.
