This study evaluated psychometric properties of interview, self-report, and screening versions of the Child PTSD Symptom Scale for DSM-5 (CPSS-5), a measure of posttraumatic stress disorder (PTSD) for traumatized youth based on DSM-5 criteria. Participants were 64 children and adolescents (51.6% female, 45.3% African American/Black) between 8 and 18 years of age (M = 14.1, SD = 2.5) who had experienced a DSM-5 Criterion A trauma. Participants completed test-retest procedures for the self-report and interviewer versions of the CPSS-5 in 2 visits that were up to 2 weeks apart. Analyses revealed excellent internal consistencies, good to excellent test-retest reliability, and good convergent validity and discriminant validity for interview and self-report versions of the scale. Receiver operating characteristic analysis yielded a cutoff score of 31 on the CPSS-5 self-report version for identifying probable PTSD diagnosis. Six most frequently endorsed items by those with a possible PTSD diagnosis on the CPSS-5 were identified to constitute a screen version of the CPSS-5, showing good internal consistency and test-retest reliability. The three versions of the CPSS-5 scales are valid and reliable measures of DSM-5 PTSD symptomatology in traumatized youth.
本研究评估了基于 DSM-5 标准为创伤后青少年设计的创伤后应激障碍（PTSD）测量工具——DSM-5 儿童 PTSD 症状量表（CPSS-5）的访谈、自我报告和筛查版本的心理测量特性。参与者为 64 名 8 至 18 岁（51.6%为女性，45.3%为非裔美国人/黑人）的儿童和青少年，他们经历了 DSM-5 标准 A 的创伤。参与者在最多相隔 2 周的 2 次访视中完成了 CPSS-5 自我报告和访谈版本的测试-重测程序。分析结果显示，该量表的访谈和自我报告版本具有极好的内部一致性、良好至极好的重测信度以及良好的聚合效度和区分效度。CPSS-5 自我报告版本的受试者工作特征分析得出了 31 分的截断值，用于识别可能的 PTSD 诊断。通过 CPSS-5 确定为可能患有 PTSD 的人最常认可的 6 个项目被确定为 CPSS-5 的筛查版本，显示出良好的内部一致性和重测信度。CPSS-5 的三个版本都是针对创伤后青少年 DSM-5 PTSD 症状的有效且可靠的测量工具。
