This study attempted to estimate the prevalence of dissociative symptoms and disorders in a Canadian adult psychiatric inpatient population and also attempted to determine the extent to which dissociative disorders were recognized by the attending clinical staff.
All appropriate and consenting adult psychiatric inpatients at the Kingston Psychiatric Hospital in Kingston, Ontario, were given the Dissociative Experiences Scale. Patients scoring 25 or greater were interviewed with the Dissociative Disorders Interview Schedule and the Structured Clinical Interview for DSM-IV Dissociative Disorders. Admission or discharge diagnoses data were used to determine whether or not dissociative disorders were being recognized.
A total of 48 patients completed the Dissociative Experiences Scale and 14 (29%) scored 25 or greater. The prevalence of dissociative disorders in this hospital population was estimated to be 17%. Dissociative identity disorder was found in six percent, dissociative amnesia in eight percent and dissociative disorder not otherwise specified in two percent of the population. These disorders tended to be under-recognized.
Research on more extensive populations is required to establish the true prevalence of dissociative symptoms and disorders in psychiatric inpatients.
本研究试图估算加拿大成年精神科住院患者中分离症状及障碍的患病率，并确定主治临床工作人员对分离障碍的识别程度。
安大略省金斯顿市金斯顿精神病院所有符合条件且同意参与的成年精神科住院患者均接受了分离体验量表测试。得分25分及以上的患者接受了分离障碍访谈量表和《精神疾病诊断与统计手册》第四版（DSM-IV）分离障碍结构化临床访谈。采用入院或出院诊断数据来确定分离障碍是否被识别。
共有48名患者完成了分离体验量表测试，其中14名（29%）得分25分及以上。据估计，该医院人群中分离障碍的患病率为17%。分离性身份障碍的患病率为6%，分离性遗忘症为8%，未另行规定的分离障碍为2%。这些障碍往往未得到充分识别。
需要对更广泛的人群进行研究，以确定精神科住院患者中分离症状及障碍的真实患病率。
