The Effect of Simulation Training based on the Jennings Disaster Nursing Management Model on Nursing Students’ Disaster Preparedness Perception and Intervention Self-Efficacy

Abstract

Background:

Strengthening nursing students’ disaster preparedness and response capacity is fundamental for effective disaster management.

Objectives:

This study aimed to examine the effect of simulation training that was based on the Jennings Disaster Nursing Management Model on nursing students’ perception of disaster preparedness and response self-efficacy.

Methods:

The study had a pretest–posttest parallel controlled quasi-experimental design and was conducted in a nonrandomized cohort of senior students. The participants were studying at the Faculty of Nursing between October, 2024 and January, 2025. Of the 130 nursing students, 65 were assigned to the intervention group and 65 to the control group. In the study, the intervention group participated in a 14-week training program, including theoretical and simulation practices based on the Jennings Disaster Nursing Management Model. Data were collected with the Introductory Information Form, the Perception of Disaster Preparedness in Nurses Scale, and Disaster Intervention Self-Efficacy Scale and analyzed using chi-square and t-tests while effect sizes were estimated with Cohen’s d.

Results:

Following simulation training, the intervention group had significantly higher total posttest scores on the Disaster Preparedness Perception Scale than the control group (t = 12.92, P < .001, d = 2.267). Additionally, total posttest scores on the Nurses’ Disaster Response Self-efficacy scale were significantly higher in the intervention group compared with the control group (t = 9.55, P < .001, d = 1.675).

Conclusion:

Simulation training enhanced nursing students’ disaster self-efficacy, highlighting the value of evidence-based simulations in nursing education for effective disaster care.
