目前的研究评估了儿童创伤后应激障碍检查表的基本心理特性，并在南非青年的大样本中检查了创伤后应激障碍（PTSD）症状的结构。1 025名（540名男性; 485名女性）南非青年（年龄在10至19岁之间）填写了该清单。量表的因素结构进行了评估与验证性和探索性技术相结合。用Cronbach's alpha和McDonald's omega评价全量表和所有分量表的内部效度。通过比较有和没有经历过创伤性事件的儿童的PTSD评分，以及通过检查PTSD总评分与已知PTSD相关因素之间的关联来评估有效性。儿童创伤后应激障碍检查表上的分数明显区分了经历过创伤事件和没有经历过创伤事件的年轻人。内部测试的完整规模（和所有分量表）是可以接受的良好和假设的相关性创伤后应激障碍，抑郁，焦虑，躯体症状，和年龄进行了观察。三重DSM-IV-TR创伤后应激障碍模型的两个报告的拟合统计量不符合传统标准，进一步的探索性分析揭示了一个四因素结构（与Simms及其同事的创伤后应激障碍症状的Dysterolia模型大致一致），这为观察到的数据提供了更好的拟合。鉴于在南非继续使用儿童创伤后应激障碍清单，调查结果提供了重要的第一步，建立用于南非青年的清单的可靠性和有效性。然而，在就清单在这方面作为诊断工具的使用得出结论之前，显然需要对南非样本中的清单进行进一步评价。
The current study assessed the basic psychometric properties of the Child PTSD Checklist and examined the structure of symptoms of posttraumatic stress disorder (PTSD) in a large sample of South African youth. The checklist was completed by 1025 (540 male; 485 female) South African youth (aged between 10 and 19 years). The factor structure of the scale was assessed with a combination of confirmatory and exploratory techniques. Internal consistencies for the full scale and all subscales were evaluated with Cronbach’s alpha and McDonald’s omega. Validity was assessed by comparing PTSD scores obtained by children who had and had not experienced a traumatic event, and by examining associations between total PTSD scores and known correlates of PTSD. Scores on the Child PTSD Checklist clearly discriminated between youth who had experienced a traumatic event and those who had not. Internal consistencies for the full scale (and all subscales) were acceptable to good and hypothesized correlations between PTSD, depression, anxiety, somatic symptoms, and age were observed. Two of the reported fit statistics for the tripartite DSM-IV-TR model of PTSD did not meet traditional criteria and further exploratory analyses revealed a four-factor structure (broadly consistent with Simms and colleagues’ Dysphoria Model of PTSD symptoms) which provided a better fit to the observed data. Given the continued use of the Child PTSD Checklist in South Africa, findings offer an important first step in establishing the reliability and validity of the checklist for use with South African youth. However, further evaluation of the checklist in South African samples is clearly required before conclusions regarding its use as diagnostic tool in this context can be made.
