There is a long history of scholarly interest on depersonalization-derealization (DD) and its role in clinical anxiety, but there is a paucity of appropriate assessment instruments available. Our objective was to develop and evaluate a self-report measure of DD for use with clinically anxious patients. Panic disorder patients (n=169) were surveyed about DD experiences and provided data on a new item pool for psychometric development. DD episodes were common and a 28-item Depersonalization-Derealization Inventory was found to possess good reliability and validity. DD appears to be prevalent and clinically relevant in panic disorder. Continued study of DD is warranted and may be facilitated by the availability of a suitable instrument with promising psychometric properties. A 12-item version of the instrument may be appropriate as a brief screen.
学术界对人格解体-现实解体（DD）及其在临床焦虑中的作用有着长期的研究兴趣，但可用的合适评估工具却很少。我们的目标是开发并评估一种用于临床焦虑患者的DD自我报告测量方法。对惊恐障碍患者（n = 169）进行了关于DD体验的调查，并提供了用于心理测量学开发的新项目库的数据。DD发作很常见，发现一份包含28个条目的人格解体-现实解体量表具有良好的信度和效度。DD在惊恐障碍中似乎很普遍且具有临床相关性。对DD的持续研究是有必要的，而一种具有良好心理测量特性的合适工具的可用性可能会促进这一研究。该工具的一个12个条目的版本可能适合作为一个简短的筛查工具。
