INTRODUCTION
Terrorist attacks are one of the human problems that affect many countries, leaving behind a huge toll of disabilities and deaths. The aim of this study was to use a mixed-method analysis to design and validate an evaluation tool for pre-hospital emergency medical services for terrorist attacks.
METHODS
The present study is a mixed-method (qualitative and quantitative) study that was conducted in two phases. In the qualitative phase (item generation), semi-structured interviews were conducted with 34 Iranian emergency medical technicians who were selected through a purposive sampling method and a scoping literature review was conducted to generate an item pool for the preparedness evaluation of Emergency Medical Services (EMS) in terrorist attacks. In the quantitative phase (item reduction), for validity of tool face, content and construct validity, were performed; for tool reliability, the test and retest and intra-class correlation coefficient were evaluated.
RESULTS
At the first stage, 7 main categories and 16 subcategories were extracted from the data, the main categories including "Policy and Planning", "Education and Exercise "," Surge Capacity", "Safety and Security", "Command, Control and Coordination", "Information and Communication Management "and "Response Operations Management". The initial item pool included 160 items that were reduced to 110 after assessment of validity (face, content and construct). intra-class correlation coefficient (ICC = 0.71) examination and Pearson correlation test (r = 0.81) indicated that the tool was also reliable.
CONCLUSION
The research findings provide a new perspective to understand the preparedness of pre-hospital emergency medical services for terrorist attacks. The existing 110-item tool can evaluate preparedness of pre-hospital emergency medical services for terrorist attacks through collecting data with appropriate validity and reliability.
简介
恐怖袭击是影响许多国家的人类问题之一，造成了巨大的残疾和死亡人数。本研究旨在采用混合方法（定性和定量）分析来设计和验证用于恐怖袭击院前紧急医疗服务的评估工具。
方法
本研究是一项混合方法（定性和定量）研究，分为两个阶段进行。在定性阶段（项目生成），通过目的抽样法选择了 34 名伊朗紧急医疗技术员进行半结构式访谈，并进行了范围综述文献检索，以生成针对恐怖袭击的紧急医疗服务（EMS）准备情况评估的项目池。在定量阶段（项目减少），对工具的表面效度、内容效度和结构效度进行了评估；为了评估工具的可靠性，进行了测试重测和组内相关系数评估。
结果
在第一阶段，从数据中提取了 7 个主要类别和 16 个子类别，主要类别包括“政策和规划”、“教育和演习”、“应急能力”、“安全和保障”、“指挥、控制和协调”、“信息和通信管理”以及“响应行动管理”。初始项目池包括 160 个项目，经过有效性（表面、内容和结构）评估后减少到 110 个。组内相关系数（ICC=0.71）检验和 Pearson 相关检验（r=0.81）表明该工具也具有可靠性。
结论
研究结果为了解院前紧急医疗服务对恐怖袭击的准备情况提供了新的视角。现有的 110 个项目工具可以通过收集具有适当有效性和可靠性的数据来评估院前紧急医疗服务对恐怖袭击的准备情况。
