The aim of this study is to investigate the psychometrics of the Dutch version of the Child and Adolescent Trauma Screener (CATS-2). By this, an international recognized instrument to screen symptoms of post-traumatic stress (PTSS) in children and adolescents according to the Diagnostic and Statistical Manual for Mental Disorders, 5th edition (DSM-5) becomes available for Dutch youth. Based on the validated CATS-2 we established the Dutch version, named the KJTS. A total of 587 children and adolescent, age 7-21, and 658 caregivers referred to mental health care services in Amsterdam was included in the study to examine psychometric properties. The construct was tested by confirmatory factor analysis (CFA). Furthermore reliability, convergent-divergent patterns and diagnostic test accuracy were examined. The underlying DSM-5 factor structure with four symptom clusters (re-experiencing, avoidance, negative alterations in mood and cognitions, hyperarousal) was supported by CFA showing a good fit for the selfreport (CFI = .95, TLI = .94), and an acceptable fit for the caregiver report (CFI = .90, TLI = .89). The KJTS showed excellent reliability (alpha = .92) on both selfreport and caregiver report. The convergent-discriminant validity pattern showed medium to strong correlations with measures of internalization problems, such as anxiety and affective problems ( = .44-.72) and low to medium correlations with externalizing symptoms ( = .21-.36). The ROC-curve analysis has proven a good accuracy (AUC = .81; = 106). This study demonstrates the psychometric accuracy of the KJTS in a Dutch clinical population. The KJTS reflects adequately the dimensionality of PTSD as described in the DSM-5, with a good fit for selfreports, an acceptable fit for caregiver reports, excellent reliability and sufficient validity. Limitations are described. The outcomes support the use of the KJTS in research and clinical practice for screening and monitoring of PTSS.
本研究的目的是调查荷兰版儿童与青少年创伤筛查工具（CATS-2）的心理测量学特性。通过这项研究，一种根据《精神疾病诊断与统计手册》第5版（DSM-5）筛查儿童和青少年创伤后应激症状（PTSS）的国际认可工具可供荷兰青少年使用。基于经过验证的CATS-2，我们建立了荷兰版，命名为KJTS。共有587名7至21岁的儿童和青少年以及658名转介至阿姆斯特丹心理健康服务机构的照料者被纳入研究，以检验心理测量学特性。通过验证性因子分析（CFA）对结构进行了测试。此外，还检验了信度、聚合-区分模式和诊断测试准确性。CFA支持了DSM-5中具有四个症状群（再体验、回避、情绪和认知的消极改变、过度警觉）的潜在因子结构，自我报告显示拟合良好（CFI = 0.95，TLI = 0.94），照料者报告显示拟合可接受（CFI = 0.90，TLI = 0.89）。KJTS在自我报告和照料者报告上均显示出优异的信度（α = 0.92）。聚合-区分效度模式显示与内化问题测量指标（如焦虑和情感问题）存在中等至强的相关性（r = 0.44 - 0.72），与外化症状存在低至中等的相关性（r = 0.21 - 0.36）。ROC曲线分析已证明具有良好的准确性（AUC = 0.81；p = 106）。本研究证明了KJTS在荷兰临床人群中的心理测量学准确性。KJTS充分反映了DSM-5中描述的创伤后应激障碍的维度，自我报告拟合良好，照料者报告拟合可接受，信度优异，效度充分。文中描述了局限性。研究结果支持在研究和临床实践中使用KJTS来筛查和监测PTSS。
