Depersonalization-Derealization disorder (DDD) is a psychiatric condition characterized by persistent feelings of detachment from one's self and of unreality about the outside world. This review aims to examine the prevalence of DDD amongst different populations. A systematic review protocol was developed before literature searching. Original articles were drawn from three electronic databases and included only studies where prevalence rates of DDD were assessed by standardized diagnostic tools. A narrative synthesis was conducted. Twenty-three papers were identified and categorized into three groups of participants: general population, mixed in/outpatient samples, and patients with specific disorders. The prevalence rates ranged from 0% to 1.9% amongst the general population, 5-20% in outpatients and 17.5-41.9% in inpatients. In studies of patients with specific disorders, prevalence rates varied: 1.8-5.9% (substance abuse), 3.3-20.2% (anxiety), 3.7-20.4% (other dissociative disorders), 16.3% (schizophrenia), 17% (borderline personality disorder), ~50% (depression). The highest rates were found in people who experienced interpersonal abuse (25-53.8%). The prevalence rate of DDD is around 1% in the general population, consistent with previous findings. DDD is more prevalent amongst adolescents and young adults as well as in patients with mental disorders. There is also a possible relationship between interpersonal abuse and DDD, which merits further research.
人格解体-现实解体障碍（DDD）是一种精神科疾病，其特征为持续存在自我疏离感和对外界不真实感。本综述旨在探讨不同人群中 DDD 的患病率。在文献检索之前制定了系统评价方案。原始文章来自三个电子数据库，仅包括通过标准化诊断工具评估 DDD 患病率的研究。进行了叙述性综合。确定了 23 篇论文，并将其分为三组参与者：一般人群、混合门诊/住院样本和特定疾病患者。一般人群中 DDD 的患病率从 0%到 1.9%不等，门诊患者为 5-20%，住院患者为 17.5-41.9%。在特定疾病患者的研究中，患病率有所不同：1.8-5.9%（物质滥用），3.3-20.2%（焦虑症），3.7-20.4%（其他分离性障碍），16.3%（精神分裂症），17%（边缘型人格障碍），~50%（抑郁症）。在经历人际虐待的人群中，患病率最高（25-53.8%）。DDD 的患病率在一般人群中约为 1%，与之前的研究结果一致。DDD 在青少年和年轻人以及精神障碍患者中更为普遍。人际虐待与 DDD 之间也可能存在关联，值得进一步研究。
