Delusional misidentification syndromes (DMS) are beginning to be well described clinically but little is known about their epidemiology. To try and obtain an estimate of their prevalence, a survey was performed of all admissions to a locked psychiatric inpatient unit from April 1983 to June 1984. 26 patients satisfied clinical criteria for DMS during this time and overall 835 patients were admitted to the unit. Thus, a crude prevalence of 3.1% was found. The median age of the patients was 29 years. The overwhelming majority had a principal psychiatric diagnosis of paranoid schizophrenia and only 2 of an affective disorder. By a small margin, most patients were male. The implications and limitations of these findings are discussed.
妄想性身份识别障碍（DMS）在临床上开始得到充分描述，但对其流行病学情况却知之甚少。为了尝试估算其患病率，对1983年4月至1984年6月期间一家封闭的精神科住院单元的所有入院患者进行了一项调查。在此期间，有26名患者符合DMS的临床标准，该单元共收治了835名患者。因此，发现其粗患病率为3.1%。患者的年龄中位数为29岁。绝大多数患者的主要精神科诊断为偏执型精神分裂症，只有2例为情感障碍。男性患者略占多数。讨论了这些发现的意义和局限性。
