A standardized tool, the Disaster Preparedness Evaluation Tool (DPET), originally published in English, is available for the purpose of assessing the level of disaster preparedness among nurses, however, a Spanish version is yet to be developed. The purpose of this study was twofold: first, to prepare a Spanish version of the DPET (DPET-SP), and secondly, to analyse the psychometric properties of the new Spanish version.
The target population comprised nurses in the region of Asturias, Spain. Cronbach's alpha (internal consistency) and item-total correlations (item discrimination) were used to test the reliability of the tool. Construct validity was tested using confirmatory factor analysis. The content validity of the Spanish version was estimated using the scale-level content validity index. The appropriateness of the factor analysis was tested using the Kaiser-Meyer-Ollin test. Sphericity of the correlation matrix was examined using Barlett's test. Principal component analysis (PCA) was utilized to categorise the measurement instrument into salient factors. Convergent validity was assessed using Average Variance Extracted (AVE).
The PCA determined that the 45 items could be grouped into five factors Cronbach's alpha value was 0.964, the AVE values for the five constructs ranged from 0.51 to 0.71, the goodness-of-fit of the model structure was good, the convergence reliability values ranged from 0.80 to 0.95 and the square root of the AVE of each individual factor must be greater than all other correlations between pairs of constructs, so there is divergent validity.
The DPET-SP has adequate validity and reliability. Therefore, it can be utilised by nurses for whom Spanish is their first language.
一种标准化工具——灾难准备评估工具（DPET），最初以英文发表，可用于评估护士的灾难准备水平，然而，其西班牙语版本尚未开发。本研究有两个目的：第一，编制DPET的西班牙语版本（DPET-SP）；第二，分析新西班牙语版本的心理测量特性。
目标人群包括西班牙阿斯图里亚斯地区的护士。使用克朗巴哈系数（内部一致性）和项目-总分相关性（项目区分度）来测试该工具的信度。使用验证性因子分析来测试结构效度。使用量表水平的内容效度指数来估计西班牙语版本的内容效度。使用凯泽-迈耶-奥尔金检验来测试因子分析的适用性。使用巴特利特检验来检验相关矩阵的球形度。利用主成分分析（PCA）将测量工具分类为显著因子。使用提取平均方差（AVE）来评估收敛效度。
主成分分析确定45个项目可分为五个因子。克朗巴哈系数值为0.964，五个结构的AVE值范围为0.51至0.71，模型结构的拟合优度良好，收敛信度值范围为0.80至0.95，且每个单独因子的AVE平方根必须大于各结构对之间的所有其他相关性，因此具有区分效度。
DPET-SP具有足够的效度和信度。因此，它可供以西班牙语为母语的护士使用。
