The aim of this study was to adapt the Chinese version of Hospital Nursing Department Disaster Preparedness Scale (HNDDPS) and evaluate the psychometric properties among hospital nurses in China. Two specific objectives were (1) to adapt the HNDDPS from Sadiq's Organisational Disaster Preparedness Scale (SODPS) to fit the context of Chinese hospital nursing system and (2) to establish its validity and reliability.
Instrument design study.
2657 nurses belonging to 50 nursing organisations of tertiary hospitals spread across seven administrative regions of China.
We adapted the Chinese version of HNDDPS through translation of the SODPS, back translation and cultural adaptation. Subsequently, we evaluated the validity of the scale through exploratory factor analysis and confirmatory factor analysis (CFA), each performed on half of the original sample. We also evaluated the internal consistency reliability of the scale.
The Chinese version of HNDDPS comprised five dimensions, with 72 items. Exploratory factor analysis yielded five factors explaining 61% of the items' variance. CFA confirmed five dimensions of the scale and produced appropriate Goodness of Fit Indexes. Cronbach's α-coefficient was 0.930 for the total scale and ranged from 0.908 to 0.964 for the five dimensions of the scale.
HNDDPS demonstrates good internal consistency and construct validity. It is a promising, valid and reliable tool for nurses and nursing managers to evaluate hospital nursing department disaster preparedness.
本研究旨在改编中文版医院护理部灾难准备量表（HNDDPS），并评估其在中国医院护士中的心理测量学特性。具体目标有两个：（1）从萨迪克组织灾难准备量表（SODPS）改编HNDDPS，以适应中国医院护理系统的背景；（2）建立其有效性和可靠性。
工具设计研究。
来自中国七个行政区50家三级医院护理组织的2657名护士。
我们通过对SODPS进行翻译、回译和文化调适来改编中文版HNDDPS。随后，我们通过探索性因素分析和验证性因素分析（CFA）评估该量表的有效性，每项分析均在原始样本的一半上进行。我们还评估了该量表的内部一致性可靠性。
中文版HNDDPS包括五个维度，共72个条目。探索性因素分析得出五个因素，解释了61%的条目方差。CFA证实了该量表的五个维度，并产生了合适的拟合优度指标。总量表的Cronbach's α系数为0.930，量表的五个维度的α系数范围为0.908至0.964。
HNDDPS具有良好的内部一致性和结构效度。它是护士和护理管理者评估医院护理部灾难准备情况的一个有前景、有效且可靠的工具。
