Nurses’ Perceptions of Disaster Core Competencies Scale

The scale consists of 5 subscales, a total of 45 items (critical thinking skills, special diagnostic skills, general diagnostic skills, technical skills, and communication skills). The response ranging from 1 to 5 point. And the Cronbach’s α is 0.96

The level of disaster core competency of nurses was higher than average. It was positively correlated with psychological resilience and had a strong correlation with disaster experience

(Hong, Jung, & Woo, 2022) [46]

The Korean version of the Disaster Preparedness Evaluation Tool

28 items were scored on a 6-point Likert scale, including disaster education training, disaster knowledge and information; bioterrorism and emergency response; and disaster assessment. The Cronbach’s alpha of DPET-K is 0.954

The average score of disaster competencies was 84.08 ± 24.74 out of 168, and the prevention stage was the highest

(Jang, Kim, & Lee, 2022) [47]

the Disaster Nursing Preparedness-Response Competency

The scale focus on the disaster nursing preparedness competency and disaster nursing response competency, including 34 items, and each item rating on five-point. The Cronbach’s alpha is 0.96, and the reliability is 0.91–0.92 in this study

The mental health nurses’ disaster nursing competencies scores was 115.12 ± 16.38 out of 170. The influencing factors included compassion satisfaction, disaster nursing experience, and disaster nursing training

Nurses had an excellent grasp of COVID-19, but most needed to gain experience in isolation ward work and emergency training

(Song, Li, Bell, Yang, & Zhang, 2021) [50]

Modified core emergency response competency questionnaire

Nurses' core emergency response ability for major infectious diseases was at a medium level, and the influencing factors were infectious disease emergency drills, academic qualifications, and work experience in infectious disease nursing
