In this study, the "Disaster Nursing" course, which was integrated into the nursing curriculum, was an elective course, and it was carried out as a theoretical course for two hours a week. The purpose of its development was to educate students on disaster management and disaster nursing [54]. The course content included identification of risks and resources for disasters at the primary protection level, nurse's caregiver (triage and holistic care) and case manager role at the secondary protection level, reassessment of individuals' care needs at the tertiary level, and review of education and the current disaster plan at the protection level. The disaster nursing course was intended to develop students' perception of disaster awareness, preparedness, and response self-efficacy by providing them with primary, secondary, and tertiary level protection roles

In this study, the "Disaster Nursing" course, which was integrated into the nursing curriculum, was an elective course, and it was carried out as a theoretical course for two hours a week. The topics in the content of this course regarding prevention, preparedness, response and recovery stages were designed in line with Jennings Disaster Nursing Management Model. The purpose of its development was to educate students on disaster management and disaster nursing. The course content included identification of risks and resources for disasters at the primary protection level, nurse's caregiver (triage and holistic care) and case manager role at the secondary protection level, reassessment of individuals' care needs at the tertiary level, and review of education and the current disaster plan at the protection level.

The conceptual framework of the 61-item scale consists of 16 domains.There are no reverse coded items in the scale. For ease of score calculation, the total score was standardized in the range of 0-50: Formula = Index = (arithmetic mean - 1) x [50/4]. With the calculated formula, cut-off points for harm reduction, preparedness, response and recovery dimensions were determined by SS values based on z-score. On the scale, 0 represents the lowest DLS and 50 represents the highest DLS. "The scale is categorized as inadequate DLS between 0-<30 points, limited DLS between 30-<36 points, adequate DLS between 36-<42 points, and excellent DLS between 42-50 points. As the scores increase in the scale, the disaster literacy level of the participant increases.

This scale, which contains 20 items in total, consists of three sub-dimensions.The five-point Likert type scale includes the options "1-Strongly disagree, 2-Disagree, 3-Somewhat agree, 4-Agree, 5-Strongly agree" for rating. The higher the score obtained from the scale, the higher the perception of disaster preparedness.
