Natural disasters are potentially traumatic events due to their disruptive nature and high impact on social and physical environments, particularly for children and adolescents. The present study aimed to examine the psychometric properties of the Children's Revised Impact of Event Scale (CRIES‐13) in a sample of Portuguese children and adolescents exposed to a specific type of natural disaster (i.e., wildfire). The sample was recruited at six school units of the Central region of Portugal following wildfires in the summer of 2017 and included children and adolescents without a clinical diagnosis of a psychopathological condition associated with exposure to the traumatic event (i.e., nonclinical sample, n = 486) and those with a clinical diagnosis of a trauma‐ and/or stress‐related disorder (i.e., posttraumatic stress disorder [PTSD], adjustment disorder, separation anxiety disorder, or grief; clinical sample, n = 54). Confirmatory factor analyses indicated that a two‐factor model (i.e., Intrusion/Arousal and Avoidance) provided a better fit than a three‐factor model (i.e., Intrusion, Arousal, and Avoidance) and was found to be invariant across gender and age groups. The CRIES‐13 showed good reliability for all subscales, with Cronbach's αs > .79. Higher CRIES‐13 scores were associated with poorer health and well‐being and more internalizing and externalizing problems. The clinical sample presented with significantly higher CRIES‐13 scores than the nonclinical sample, η_p² = .13. These results contribute to the cross‐cultural validation of the CRIES‐13 and support its use as a reliable and valid measure for assessing posttraumatic symptoms in children and adolescents.

儿童修订的事件影响量表：暴露于野火的儿童和青少年样本的维度和测量不变性

自然灾害是潜在的创伤性事件，因为它们具有破坏性和对社会和自然环境的重大影响，特别是对儿童和青少年。本研究旨在检查暴露于特定类型自然灾害（即野火）的葡萄牙儿童和青少年样本中儿童修订的事件影响量表 (CRIES-13) 的心理测量特性。该样本是在 2017 年夏季发生野火后在葡萄牙中部地区的六个学校单位招募的，其中包括没有临床诊断出与暴露于创伤事件相关的精神病理状况的儿童和青少年（即，非临床样本，n= 486) 以及临床诊断为创伤和/或压力相关障碍的患者（即，创伤后应激障碍 [PTSD]、适应障碍、分离焦虑障碍或悲伤；临床样本，n = 54）。验证性因素分析表明，双因素模型（即入侵/唤醒和回避）比三因素模型（即入侵、唤醒和回避）提供了更好的拟合，并且发现在不同性别和年龄组之间是不变的. CRIES-13 在所有分量表中都显示出良好的信度，Cronbach αs > .79。较高的 CRIES-13 分数与较差的健康和幸福感以及更多的内化和外化问题相关。临床样本的 CRIES-13 评分显着高于非临床样本，η _p ²= .13。这些结果有助于 CRIES-13 的跨文化验证，并支持将其用作评估儿童和青少年创伤后症状的可靠和有效的措施。
