[目的]建立汶川地震后儿童创伤后应激障碍(PTSD)各症状关系的结构方程模型,分析不同性别组儿童各症状的表现。[方法]采用儿童事件影响量表(CRIES-13)调查253名汶川地震灾区儿童PTSD的相关症状信息,构建结构方程模型,通过评价修正确定最佳模型。对灾后不同性别组儿童PTSD各症状内容和形式的特点进行比较。[结果]从CRIES-13提取了3个PTSD的潜变量,即闯入症状、回避症状和警觉症状,并引入一个总因子潜变量。模型拟合效果良好,不同性别组的结构方程模型形态相同,模型能解释不同性别组儿童各症状表现的特点。[结论]CRIES-13的测量形式是适合不同性别组儿童的,参考此次研究结果有助于灾后更有效地筛查PTSD儿童,为解决灾后儿童心理卫生问题提供帮助。
[Objective] To establish the structural equation model of the relationship between various symptoms of posttraumatic stress disorder (PTSD) in Wenchuan earthquake and analyze the manifestations of various symptoms in children of different genders. [Methods] The CRTS-13 was used to investigate the related symptoms information of 253 PTSD children in Wenchuan earthquake-stricken area. The structure equation model was constructed and the best model was determined through the evaluation and revision. After the disaster in different gender groups PTSD symptoms and contents of the content of the form of characteristics were compared. [Results] Three latent variables of PTSD were extracted from CRIES-13, namely break-in symptoms, avoidance of symptoms and vigilance symptoms, and introduce a total factor latent variable. The model fitting effect is good, the structural equation models of different genders are the same in shape, and the model can explain the characteristics of each symptom of children in different sex groups. [Conclusion] The measurement of CRIES-13 is suitable for children of different gender groups. Reference to the results of this study is helpful to screen children with PTSD more effectively and help to solve the psychological health problems of children after disaster.
