BACKGROUND
The study examined the psychometric properties of the Child and Adolescent Trauma Screen 2 (CATS-2) as a measure of posttraumatic stress disorder (PTSD) according to DSM-5 and (Complex) PTSD following the ICD-11 criteria in children and adolescents (7-17 years).
METHODS
Psychometric properties were investigated in an international sample of traumatized children and adolescents ( = 283) and their caregivers ( = 255). We examined the internal consistency (α), convergent and discriminant validity, the factor structure of the CATS-2 total scores, latent classes of PTSD/Complex PTSD (CPTSD) discrimination, as well as the diagnostic utility using ROC-curves.
RESULTS
The DSM-5 total score (self: α = .89; caregiver: α = .91), the ICD-11 PTSD total score (self: α = .67; caregiver: α = .79) and the ICD-11 CPTSD total score (self: α = .83; caregiver: α = .87) have proven acceptable to excellent reliability. The latent structure of the 12-item ICD-11 PTSD/CPTSD construct was consistent with prior findings. Latent profile analyses revealed that ICD-11 CPTSD was empirically distinguishable from ICD-11 PTSD using the CATS-2. ROC-analysis using the CAPS-CA-5 as outcome revealed that CATS-2 DSM-5 PTSD scores of ≥21 (screening) to ≥25 (diagnostic) were optimally efficient for detecting probable DSM-5 PTSD diagnosis. For the ICD-11 PTSD scale scores of ≥7 (screening) to ≥9 (diagnostic) were optimally efficient for detecting probable DSM-5 PTSD diagnosis.
CONCLUSIONS
The CATS-2 is a brief, reliable and valid measure of DSM-5 PTSD, ICD-11 PTSD and CPTSD symptomatology in traumatized children and adolescents, allowing crosswalk between diagnostic systems using one measure.
HIGHLIGHTS
The CATS-2 screens for potentially traumatic events (PTEs) and PTSD symptoms.The CATS-2 captures DSM-5 and ICD-11 criteria for PTSD and CPTSD and enables clinicians and researchers to crosswalk between both diagnostic systems.International validation has proven good psychometric properties and presents cut-off scoresThe CATS-2 is a license-free instrument and is freely accessible.
背景
本研究根据 DSM-5 和 ICD-11 标准，对儿童和青少年（7-17 岁）创伤后应激障碍（PTSD）和（复杂）创伤后应激障碍（CPTSD）的儿童和青少年创伤筛查 2 （CATS-2）进行了心理测量学特性的评估。
方法
我们对国际创伤儿童和青少年样本（n=283）及其照顾者（n=255）进行了心理测量学评估。我们检验了 CATS-2 总分的内部一致性（α）、收敛和区分效度、因素结构、PTSD/CPTSD（CPTSD）的潜在类别区分，以及使用 ROC 曲线的诊断效用。
结果
DSM-5 总分（自评：α=0.89；照顾者：α=0.91）、ICD-11 PTSD 总分（自评：α=0.67；照顾者：α=0.79）和 ICD-11 CPTSD 总分（自评：α=0.83；照顾者：α=0.87）均具有可接受的至极好的可靠性。12 项 ICD-11 PTSD/CPTSD 结构的潜在结构与先前的研究结果一致。潜在剖面分析显示，使用 CATS-2，ICD-11 CPTSD 在实证上可与 ICD-11 PTSD 区分开来。使用 CAPS-CA-5 作为结果的 ROC 分析表明，CATS-2 DSM-5 PTSD 得分≥21（筛查）至≥25（诊断）对于检测可能的 DSM-5 PTSD 诊断最为有效。对于 ICD-11 PTSD 评分≥7（筛查）至≥9（诊断）对于检测可能的 DSM-5 PTSD 诊断最为有效。
结论
CATS-2 是一种简短、可靠和有效的测量工具，可用于评估创伤后儿童和青少年的 DSM-5 PTSD、ICD-11 PTSD 和 CPTSD 症状，允许使用一种测量工具在诊断系统之间进行交叉。
重点
CATS-2 可筛查潜在创伤事件（PTE）和 PTSD 症状。CATS-2 可捕捉 DSM-5 和 ICD-11 创伤后应激障碍和 CPTSD 的标准，并使临床医生和研究人员能够在两种诊断系统之间进行交叉。国际验证证明了其良好的心理测量特性，并提供了截断分数。CATS-2 是一种无许可证的工具，可免费获取。
