Abstract

Abstract: The use of patient‐reported measures in assessing mental health symptoms is common in both the research and clinical fields. With regard to assessing posttraumatic stress symptoms, there are specific versions of measures designed for child and adolescent populations in accordance with the fourth and fifth editions of the Diagnostic and Statistical Manual of Mental Disorders ( DSM‐IV and DSM‐5, respectively). Different clinical thresholds, numbers of items, and score ranges may present obstacles for clinicians and researchers attempting to compare self‐report ratings across different versions of a measure. The current study aimed to produce a score conversion crosswalk between two child/adolescent self‐report measures of posttraumatic stress disorder (PTSD): the UCLA PTSD Reaction Index for DSM‐IV (RI‐IV) and DSM‐5 (RI‐5). Using item response theory (IRT), we calibrated both measures separately to derive scaled scores. The discrimination parameters ranged from 0.57 to 2.08 ( SE = 0.09–0.17) for RI‐IV and from 0.73 to 2.11 for RI‐5 ( SE = 0.07–0.13). The scaled scores were connected with equipercentile linking. Total scores based on common items between the two measures were used as anchors to enhance the linking results. A total of 1, 486 children and adolescents completed the measure: 571 respondents filled out the RI‐IV and 915 respondents filled out the RI‐5. The results allow linked scores to be compared to establish recommended clinical cutoffs and help elucidate the implications of changes in the diagnostic criteria for the measurement of self‐reported PTSD symptoms in children and adolescents. 抽象: Traditional and Simplified Chinese Abstracts by the Asian Society for Traumatic Stress Studies (AsianSTSS) 簡體及繁體中文撮要由亞洲創傷心理研究學會翻譯 Traditional Chinese UCLA PTSD反應指數的轉換對照表 : 將DSM‐IV轉化為DSM‐5 摘要 在研究和臨床領域, 使用臨床治療者報告的方法來評估心理健康症狀是很常見的。在評估創傷後壓力症狀方面, 根據《精神疾病診斷與統計手冊》第四版和第五版(分別為DSM‐IV和DSM‐5), 有專門為兒童和青少年群體設計的措施版本。不同的臨床閾值、項目數量和得分範圍可能會給試圖在不同版本的測量中比較自我報告評分的臨床醫生和研究人員帶來壓力。目前的研究旨在產生兩種兒童/青少年創傷後壓力(PTSD)自我報告措施之間的分數轉換對照表:UCLA PTSD反應指數DSM‐IV(RI‐IV)和DSM‐5(RI‐5)。利用項目反應理論(IRT), 我們分別校準了這兩種測量方法, 以得出標度分數。 RI‐IV的辨別參數為0.57至2.08(SE=0.07‐2.11), RI‐5為0.73至2.11(SE=0.09‐0.17)。比例分數是用等百分位數聯繫起來的。基於兩種測量方法之間的共同項目的總分被用作錨, 以加強聯繫的結果。共有1486名兒童和青少年完成了測量:571名受訪者填寫了RI‐IV, 915名受訪者填寫了RI‐5。這些結果允許對聯繫分數進行比較, 以建立推薦的臨床分界線, 並幫助闡明診斷標準的變化對兒童和青少年自我報告的創傷後壓力症狀測量的影響。 Simplified Chinese UCLA PTSD 反应指数的转换对照表: 将DSM‐IV转化为DSM‐5 摘要 在研究和临床领域, 使用临床治疗者报告的方法来评估心理健康症状是很常见的。在评估创伤后压力症状方面, 根据《精神疾病诊断与统计手册》第四版和第五版(分别为DSM‐IV和DSM‐5), 有专门为儿童和青少年群体设计的措施版本。不同的临床阈值、项目数量和得分范围可能会给试图在不同版本的测量中比较自我报告评分的临床医生和研究人员带来压力。目前的研究旨在产生两种儿童/青少年创伤后压力(PTSD)自我报告措施之间的分数转换对照表:UCLA PTSD反应指数DSM‐IV(RI‐IV)和DSM‐5(RI‐5)。利用项目反应理论(IRT), 我们分别校准了这两种测量方法, 以得出标度分数。 RI‐IV的辨别参数为0.57至2.08(SE=0.07‐2.11), RI‐5为0.73至2.11(SE=0.09‐0.17)。比例分数是用等百分位数联系起来的。基于两种测量方法之间的共同项目的总分被用作锚, 以加强联系的结果。共有1486名儿童和青少年完成了测量:571名受访者填写了RI‐IV, 915名受访者填写了RI‐5。这些结果允许对联系分数进行比较, 以建立推荐的临床分界线, 并帮助阐明诊断标准的变化对儿童和青少年自我报告的创伤后压力症状测量的影响。
