Abstract

Objectives

This study translated the UCLA PTSD Reaction Index for DSM-5 into Turkish (PTSD-RI-5-TR), evaluated its psychometric properties, and examined whether PTSD symptom severity predicts functional impairment in Turkish adolescents aged 11–17.

Methods

A total of 157 trauma-exposed adolescents from a tertiary Child and Adolescent Psychiatry Clinic participated. Internal consistency and test–retest reliability were evaluated. Construct validity was examined via confirmatory factor analysis (CFA) of a five-factor model. Convergent, divergent, criterion, and known-groups validity were tested. ROC analysis assessed diagnostic accuracy. Binary logistic regression was used to evaluate the impact of scores on four functional domains.

Results

PTSD-RI-5-TR showed good internal consistency and test–retest reliability (acceptable for Category C). CFA indicated excellent fit (CMIN/DF, CFI, TLI, RMSEA) and good fit (GFI, NFI). Scores correlated strongly with NSESSS-PTSD and moderately with DES-B. PTSD diagnoses were associated with significantly higher scores. ROC analysis yielded an AUC = 0.909, sensitivity = 86.4%, specificity = 84.1% with an optimal cutoff score of 49.5. In total score models, each one-point increase predicted impairment in developmental progression (OR = 1.097), home (OR = 1.084), peer (OR = 1.071), and school functioning (OR = 1.063). In symptom cluster models, negative mood/cognition (D) most strongly predicted peer (OR = 1.205) and developmental impairment (OR = 1.155); avoidance (C) predicted home impairment (OR = 1.250); arousal/reactivity (E) predicted home (OR = 1.144) and school impairment (OR = 1.131); intrusion (B) showed no independent effect.

Conclusion

PTSD-RI-5-TR is a reliable, valid tool for assessing PTSD in Turkish adolescents. Higher total PTSD scores and higher scores in the C, D, and E symptom clusters may indicate a greater likelihood of functional impairment.

Trial Registration

This study was prospectively registered at ClinicalTrials.gov (Identifier: NCT06077474 {2023-10-05})

土耳其UCLA PTSD-RI-5：功能障碍症状严重程度的验证和作用。

目的：本研究将DSM-5中的UCLA PTSD反应指数翻译成土耳其语（PTSD- ri -5- tr），评估其心理测量特性，并探讨PTSD症状严重程度是否能预测11-17岁土耳其青少年的功能障碍。方法：对某三级儿童青少年精神病学门诊157名创伤暴露青少年进行调查。评估内部一致性和重测信度。通过五因素模型的验证性因子分析（CFA）来检验结构效度。检验了收敛、发散、标准和已知组的效度。ROC分析评估诊断的准确性。使用二元逻辑回归来评估得分对四个功能域的影响。结果：PTSD-RI-5-TR具有良好的内部一致性和重测信度（C类可接受）。CFA表示良好的拟合（CMIN/DF， CFI， TLI， RMSEA）和良好的拟合（GFI， NFI）。评分与nssess - ptsd相关性强，与DES-B相关性中等。创伤后应激障碍诊断与更高的分数显著相关。ROC分析得出AUC = 0.909，敏感性= 86.4%，特异性= 84.1%，最佳截止评分为49.5。在总分模型中，每增加1分预测发育进展（OR = 1.097）、家庭（OR = 1.084）、同伴（OR = 1.071）和学校功能（OR = 1.063）的损害。在症状聚类模型中，负性情绪/认知(D)最能预测同伴（OR = 1.205）和发育障碍（OR = 1.155）；回避(C)预测家庭损害（OR = 1.250）；唤醒/反应性(E)预测家庭（OR = 1.144）和学校损害（OR = 1.131）；入侵(B)无独立影响。结论：PTSD- ri -5- tr是一种可靠、有效的评估土耳其青少年PTSD的工具。PTSD总分越高，C、D和E症状组得分越高，可能表明功能障碍的可能性越大。试验注册：本研究在ClinicalTrials.gov上前瞻性注册（标识符：NCT06077474{2023-10-05}）。

期刊介绍： The International Journal of Methods in Psychiatric Research (MPR) publishes high-standard original research of a technical, methodological, experimental and clinical nature, contributing to the theory, methodology, practice and evaluation of mental and behavioural disorders. The journal targets in particular detailed methodological and design papers from major national and international multicentre studies. There is a close working relationship with the US National Institute of Mental Health, the World Health Organisation (WHO) Diagnostic Instruments Committees, as well as several other European and international organisations. MPR aims to publish rapidly articles of highest methodological quality in such areas as epidemiology, biostatistics, generics, psychopharmacology, psychology and the neurosciences. Articles informing about innovative and critical methodological, statistical and clinical issues, including nosology, can be submitted as regular papers and brief reports. Reviews are only occasionally accepted. MPR seeks to monitor, discuss, influence and improve the standards of mental health and behavioral neuroscience research by providing a platform for rapid publication of outstanding contributions. As a quarterly journal MPR is a major source of information and ideas and is an important medium for students, clinicians and researchers in psychiatry, clinical psychology, epidemiology and the allied disciplines in the mental health field.
