The Dissociative Symptoms Scale (DSS) was developed to assess moderately severe types of dissociation (depersonalization, derealization, gaps in awareness and memory, and dissociative reexperiencing) that would be relevant to a range of clinical populations, including those experiencing trauma-related dissociation. The current study used data from 10 ethnically and racially diverse clinical and community samples ( = 3,879) to develop a brief version of the DSS (DSS-B). Item information curves were examined to identify items with the most precision in measuring above average levels of the latent trait within each subscale. Analyses revealed that the DSS-B preserved the factor structure and content domains of the full scale, and its scores had strong reliability and validity that were comparable to those of scores on the full measure. DSS-B scores showed high levels of measurement invariance across ethnoracial groups. Results indicate that DSS-B scores are reliable and valid in the populations studied.
分离症状量表（DSS）旨在评估中度严重程度的分离症状（人格解体、现实解体、意识和记忆空白以及分离性再体验），这些症状与一系列临床人群相关，包括经历创伤相关分离的人群。本研究使用了来自 10 个不同种族和种族的临床和社区样本的数据（n=3879），开发了 DSS 的简短版本（DSS-B）。通过检查项目信息曲线，确定了在每个分量表内测量潜在特质的高于平均水平的最精确项目。分析表明，DSS-B 保留了全量表的因子结构和内容领域，其得分具有很强的信度和效度，与全量表得分相当。DSS-B 得分在不同种族群体中具有高度的测量不变性。结果表明，DSS-B 得分在研究人群中是可靠和有效的。
