The Dissociative Experiences Measure, Oxford (DEMO) is a recently developed measure that reflects the current conceptualization of dissociation. However, psychometric investigations of the DEMO are still limited. The current study examined the factor structure and psychometric properties of the Hong Kong Chinese version of the DEMO (HKC-DEMO). Online survey data on 914 community-dwelling adults in Hong Kong was extracted from a primary preregistered study on sleep and dissociation. Confirmatory factor analyses revealed that a five-factor structure, identified as "unreality," "numbness and disconnectedness," "memory blanks," "zoned out," and "vivid internal world," fit the data adequately. The five-factor structure fit significantly better than a four-factor structure, which combined "zoned out" and "vivid internal world" as a single factor of "absorption." Furthermore, the HKC-DEMO demonstrated excellent reliability, and satisfactory convergent, and divergent validity. The current study was the first to translate the DEMO to other language and showed that the HKC-DEMO is reliable and valid for use in Hong Kong Chinese adults. Further validation of the HKC-DEMO with a clinical sample and samples with a wider age range would enhance the generalizability of the HKC-DEMO.
牛津解离体验量表（DEMO）是最近开发的一种量表，它反映了当前对解离的概念化理解。然而，对DEMO的心理测量学研究仍然有限。本研究考察了牛津解离体验量表中文版（HKC-DEMO）的因子结构和心理测量学特性。关于香港914名社区居住成年人的在线调查数据，取自一项关于睡眠和解离的预先注册的初步研究。验证性因素分析表明，一个五因素结构，即“非现实感”、“麻木与脱节”、“记忆空白”、“注意力分散”和“生动的内心世界”，能较好地拟合数据。该五因素结构的拟合度显著优于四因素结构，后者将“注意力分散”和“生动的内心世界”合并为一个单一的“专注”因素。此外，HKC-DEMO表现出出色的信度，以及令人满意的聚合效度和区分效度。本研究首次将DEMO翻译成其他语言，并表明HKC-DEMO在香港成年华人中使用是可靠且有效的。使用临床样本和更广泛年龄范围的样本对HKC-DEMO进行进一步验证，将提高HKC-DEMO的可推广性。
