The Clinician-Administered PTSD Scale (CAPS) is an extensively validated and widely used structured diagnostic interview for posttraumatic stress disorder (PTSD). The CAPS was recently revised to correspond with PTSD criteria in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013). This article describes the development of the CAPS for DSM-5 (CAPS-5) and presents the results of an initial psychometric evaluation of CAPS-5 scores in 2 samples of military veterans (Ns = 165 and 207). CAPS-5 diagnosis demonstrated strong interrater reliability (к = .78 to 1.00, depending on the scoring rule) and test-retest reliability (к = .83), as well as strong correspondence with a diagnosis based on the CAPS for DSM-IV (CAPS-IV; к = .84 when optimally calibrated). CAPS-5 total severity score demonstrated high internal consistency (α = .88) and interrater reliability (ICC = .91) and good test-retest reliability (ICC = .78). It also demonstrated good convergent validity with total severity score on the CAPS-IV (r = .83) and PTSD Checklist for DSM-5 (r = .66) and good discriminant validity with measures of anxiety, depression, somatization, functional impairment, psychopathy, and alcohol abuse (rs = .02 to .54). Overall, these results indicate that the CAPS-5 is a psychometrically sound measure of DSM-5 PTSD diagnosis and symptom severity. Importantly, the CAPS-5 strongly corresponds with the CAPS-IV, which suggests that backward compatibility with the CAPS-IV was maintained and that the CAPS-5 provides continuity in evidence-based assessment of PTSD in the transition from DSM-IV to DSM-5 criteria.

创伤后应激障碍量表 (CAPS) 是一种经过广泛验证和广泛使用的创伤后应激障碍 (PTSD) 结构化诊断访谈工具。该量表最近进行了修订，以符合精神障碍诊断与统计手册第五版 (DSM-5; 美国精神病学协会，2013 年) 中的 PTSD 标准。本文介绍了用于 DSM-5 的 CAPS 的开发 (CAPS-5)，并介绍了在两个退伍军人样本中对 CAPS-5 分数进行初步心理测量评估的结果 (n1 = 165 和 n2 = 207)。CAPS-5 诊断显示出较强的评分者间可靠性 (к =.78 至 1.00，具体取决于评分规则) 和重测信度 (к =.83)，以及与基于 CAPS-IV 的诊断的强一致性 (к =.84，当最佳校准时)。CAPS-5 总分显示出较高的内部一致性 (α =.88) 和评分者间可靠性 (ICC =.91)，以及良好的重测信度 (ICC =.78)。它还与 CAPS-IV 的总分 (r =.83) 和 DSM-5 创伤后应激障碍检查表 (r =.66) 具有良好的聚合效度，与焦虑、抑郁、躯体化、功能障碍、精神病态和酒精滥用的测量指标具有良好的区分效度 (rs =.02 至.54)。总体而言，这些结果表明 CAPS-5 是一种具有心理测量学意义的 DSM-5 PTSD 诊断和症状严重程度的测量工具。重要的是，CAPS-5 与 CAPS-IV 高度一致，这表明 CAPS-IV 的向后兼容性得以保持，并且 CAPS-5 在从 DSM-IV 标准过渡到 DSM-5 标准时，为 PTSD 的循证评估提供了连续性。
