《精神疾病诊断与统计手册》（DSM-5）第五版中创伤后应激障碍（PTSD）诊断标准的变化，需要有效和可靠的最新评估工具。这项研究检查了关键的心理测量特性（e。例如，在一个实施例中，内部一致性，重测信度，评定者间信度，收敛和判别效度）的PTSD症状量表访谈DSM-5（PSSI-5），一个修改版的PSS-I（PTSD症状量表）-访谈版的DSM-IV。参与者是242名城市社区居民，退伍军人和大学本科生，从3个研究地点招募，谁经历了DSM-5标准A创伤事件。PSSI-5表现出良好的内部一致性（α =.89）和重测信度（r =.严重程度总评分（组内相关系数= 0.98）和PTSD诊断（kappa= 0.84）的评分者间一致性也非常好。PSSI-5也证明了3种PTSD测量的收敛效度（i.例如，DSM-5的临床医生-管理员PTSD量表、DSM-5的创伤后诊断量表和PTSD检查表专用版;所有rs >.72）以及Beck抑郁量表-II和状态-特质焦虑量表-特质量表的判别效度。受试者操作特征分析得出的临界值为23分，用于确定可能的PTSD诊断。总之，这些发现表明PSSI-5是评估PTSD诊断和严重程度的有效和可靠的工具。
Changes to the diagnostic criteria for posttraumatic stress disorder (PTSD) in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) create a need for valid and reliable updated assessment tools. This study examined key psychometric properties (e. g., internal consistency, test-retest reliability, interrater reliability, and convergent and discriminant validity) of the PTSD Symptom Scale Interview for DSM-5 (PSSI-5), a modified version of the PSS-I (PTSD Symptom Scale)-Interview Version for the DSM-IV. Participants were 242 urban community residents, veterans, and college undergraduates, recruited from 3 study sites, who had experienced a DSM-5 Criterion A traumatic event. The PSSI-5 demonstrated good internal consistency (alpha=.89) and test-retest reliability (r =. 87), as well as excellent interrater reliability for the total severity score (intraclass correlation =.98) and interrater agreement for PTSD diagnosis (kappa=.84). The PSSI-5 also demonstrated convergent validity with 3 measures of PTSD (i. e., Clinician-Administered PTSD Scale for DSM-5, Posttraumatic Diagnostic Scale for DSM-5, and PTSD Checklist-Specific Version; all rs >.72) and discriminant validity with the Beck Depression Inventory-II and the State-Trait Anxiety Inventory-Trait scale. Receiver operating characteristic analysis yielded a cutoff score of 23 for identifying a probable PTSD diagnosis. Together, these findings indicate that the PSSI-5 is a valid and reliable instrument for assessing PTSD diagnosis and severity.
